This is especially critical for heat pump systems to assure proper refrigerant charge balance between the cooling and heating modes. The recommended approach is to select an air-handler model that has an AHRI match with the outdoor unit. Refer to the AHRI directory at www.ahridirectory.org to confirm the air-handler and outdoor unit are a certified combination in the AHRI Directory. 2.7 IMPORTANCE OF QUALITY INSTALLATION A quality installation is critical to assure safety, reliability, comfort, and customer satisfac- tion. Strict adherence to applicable codes,the information in this installation manual, the outdoor unit installation manual, and the thermostat installation manual are key to a quality installation. Read the entire instruction manuals before starting the installation. IMPORTANT.This product has been designed and manufactured to meet certified AHRI capacity and efficiency ratings with the appropriate outdoor units. However, proper refrigerant charge, proper airflow, and refrigerant line sizing are critical to achieve opti- mum capacity and efficiency and to assure reliable operation. Installation of this prod- uct should follow the manufacturer's refrigerant charging and airflow instructions located in the outdoor unit installation instructions and the charging chart label affixed to the out- door unit. Failure to confirm proper charge and airflow may reduce energy efficiency and shorten equipment life. The equipment has been evaluated in accordance with the Code of Federal Regulations, Chapter XX, Part 3280. Install the unit in accordance with applicable national, state, and local codes. Latest edi- tions are available from: "National Fire Protection Association, Inc., Batterymarch Park, Quincy, MA 02269."These publications are: •ANSI/NFPA No.70-(Latest Edition) National Electrical Code. • NFPA90A Installation of Air Conditioning and Ventilating Systems. • NFPA90B Installation of warm air heating and air conditioning systems. Install the unit in such a way as to allow necessary access to the coil/filter rack and blower/control compartment. i 11 3.0 INSTALLATION 3.1 TOOLS & REFRIGERANT 3.1.1 TOOLS REQUIRED FOR INSTALLING AND SERVICING R-410A MODELS Manifold Sets: Ambient and Tube • Up to 800 PSIG High-Side Thermometers Crescent Wrench • Up to 250 PSIG Low-Side •550 PSIG Low-Side Retard Manifold Hoses: Allen Wrench • Service Pressure Rating of 800 PSIG Manifold - Gauge Recovery Cylinders: set •400 PSIG Pressure Rating Brazing Recovery • Dept. of Transportation Rods Cylinders 4BA400 or BW400 A NOTICE R-41 OA systems operate at higher pressures than R-22 systems. Do O O not use R-22 service equipment or compo- nents on R-410A equip- ment. Torch Reclaimer Nitrogen 3.1.2 SPECIFICATIONS OF R-410A Application: R-410A is not a drop-in replacement for R-22 Equipment designs must accommodate its higher pressures.It cannot be retrofitted into R-22 heat pumps. Physical Properties: R-41 OA has an atmospheric boiling point of-62.9°F [-52.7°C] and its saturation pressure at 77°F[25°C]is 224.5 psig. Composition: R-410A is a near-azeotropic mixture of 50% by weight difluoromethan� (HFC-32)and 50%by weight pentafluoroethane(HFC-125). Pressure:The pressure of R-410A is approximately 60%(1.6 times)greater than R- 22. Recovery and recycle equipment, pumps, hoses, and the like must have design pressure ratings appropriate for R-410A. Manifold sets need to range up to 800 psig high-side and 250 psig low-side with a 550 psig low-side retard. Hoses need to have a service pressure rating of 800 psig. Recovery cylinders need to have a 400 psig service pressure rating, DOT 4BA400 or DOT BW400. Combustibility: At pressures above 1 atmosphere, a mixture of R-410A and air can become combustible. R-410A and air should never be mixed in tanks or supply lines or be allowed to accumulate in storage tanks Leak checking should never be done with a mixture of R-410A and air. Leak-checking can be performed safely with nitrogen or a mixture of R-41 OA and nitrogen. 3.1.3 QUICK-REFERENCE GUIDE FOR R-410A • R-410A refrigerant operates at approximately 60% higher pressure (1.6 times) than R-22. Ensure that servicing equipment is designed to operate with R-41 OA. • R-41 OA refrigerant cylinders are light rose in color. • R-41 OA,as with other HFCs,is only compatible with POE oils. • Vacuum pumps will not remove moisture from POE oil used in R-41 OA systems. • R-410A systems are to be charged with liquid refrigerants. Prior to March 1999, R- 41 OA refrigerant cylinders had a dip tube. These cylinders should be kept upright for equipment charging. Post-March 1999 cylinders do not have a dip tube and should be inverted to ensure liquid charging of the equipment. • Do not install a suction line filter drier in the liquid line. • A factory-approved outdoor liquid line filter drier is shipped with every unit and must be installed in the liquid line at the time of installation. If only the air-handler is being replaced on an existing system,the existing filter drier must be replaced at the time of installation with a field supplied filter drier. IMPORTANT:A bi-flow filter drier must be used for heat pump applications. Filter driers must be rated for minimum working pressure of 600 psig.The filter drier will only have adequate moisture-holding capaci- ty if the system is properly evacuated. • Desiccant(drying agent)must be compatible for POE oils and R-410A refrigerant. 12 3.2 APPLICATIONS AND ORIENTATION 3.2.1 VERTICAL UPFLOW & HORIZONTAL LEFT DISCHARGE • Vertical Upflow & Horizontal Left Discharge is the factory configuration for all models (see Figure 4). • The return air plenum must be large enough to supply unit and strong enough to sup- port unit weight. • If return air is to be ducted through the floor, install duct flush with floor. Use fireproof. resilient gasket 1/8 to 1/4 in. thick between duct, unit and floor. Set unit on floor over opening. IMPORTANT. Do not cut the side out of air-handler cabinet for a side return duct as this will result in the return air bypassing the coil. Instead, install air-handler on top of a field supplied sheet metal or wooden box and run the side return duct into the side of the box.

To make this conversion, remove the coil door and slide the indoor coil out of the cabinet. When converting the air-handler for vertical down and horizontal right discharge applica- tions, an additional set of 2 coil support rails must be installed before the coil can be reinstalled. These additional rails are supplied with the air-handler and are packaged with the duct flanges. Six screws are also provided for mounting the rails and can be found in the installation hardware bag. Clearance holes must be drilled in the sides of the cabinet for the mounting screws using the provided dimples as guides. Note that the shorter coil support rail with no notch must be mounted on the left-hand side to provide clearance for the drainpan condensate connection boss. The vertical down/horizontal right coil support rails were not installed at the factory so the insulation under them would not be compressed which could result in exterior cabinet sweating in humid environments due to that location being in the cold downstream side of the indoor coil in vertical up and horizontal left discharge applications.The coil support rails installed at the factory should be left in place to help retain the cabinet insulation. They will be located on the warmer return side of the air-handler for down and horizontal right discharge applications and will therefore not pose a risk for cabinet sweating. Once the additional coils support rails are installed,slide the coil back into the cabinet 1800 from its original position, ensuring the retaining channel is fully engaged with the coil rail. (See Figure 6, Detail A.)Leave the coil door off until after the refrigerant tubing is brazed to the refrigerant stubs to allow TXV to be wrapped with a wet rag or heat sink compound during the brazing process. If the air-handler is not already in position, it can now be posi- tioned so the blower discharge is either down or to the right depending on the application. 13 FIGURE 5 . ROTATING CIRCUIT BREAKER i y ' DRIP LOOP NOTE: When installing the unit in down or horizontal right discharge app cations, make sure the wires going to the blower motor form a proper drip loop to forc any condensate that might form on the wires to drip off the lowest point of the wirin instead of entering the motor or motor control. This may require cutting the wire-tie an installing a new wire-tie to form a new drip loop.

(See Sections 3.3 and 6.3.) Failure to install over- flow plan can result in property damage. 3.2.3 INSTALLATION IN AN UNCONDITIONED SPACE The exterior cabinet of an air handler has a greater risk of sweating when installed in an unconditioned space than when it is installed in the conditioned space. This is primarily due to the temperature of the conditioned air moving through the air handler and the air circulating around the unit where it is installed. For this reason, the following is recom- mended for all air handler applications, but special attention should be paid to those installed in unconditioned spaces: • Duct sizing and airflow are critical and must be based on the equipment selected. • Supply and return duct attachment: If other than the factory flanges are used, the attachment of ducting must be insulated and tight to prevent sweating. 15 • No perimeter supply flanges are provided. If a full perimeter supply duct is used, it the responsibility of the installer to provide duct flanges as needed,to secure and sl the supply duct to prevent air leakage and the sweating that will result. • Apply caulking around all cabinet penetrations such as power wires, control wir( refrigerant tubing and condensate line where they enter the cabinet. Seal the povl wires on the inside where they exit conduit opening. Sealing is required to prevent leakage into the unit which can result in condensate forming inside the unit, cont box, and on electrical controls.Take care not to damage, remove or compress insu tion when applying the caulk. • In some cases, the entire air handler can be wrapped with insulation. This can done as long as the unit is completely enclosed in insulation, sealed and servil access is provided to prevent accumulation of moisture inside the insulation wrap. • An auxiliary overflow pan is recommended to protect the structure from excessi, cabinet sweating or a restricted coil drain line. (See Section 3.3) • If an electric heater kit is installed, be sure the breaker or disconnect cover is seall tightly to the door panel. 3.2.4 INSTALLATION IN MOBILE/MANUFACTURED HOMES 1. Air handler must be secured to the structure using"L"brackets or pipe strap. 2. Allow a minimum of 24 inches(610 mm)front clearance required to access doors. 3. Recommended method for securing air handler: A. If air handier is against the wall; secure top of air handler to wall stud using tv 16ga thick angle brackets one on each side.Attach brackets with No. 10 self-ta ping 1/2" long screws to air handler and use 5/16"lag screws 11/2" long to wall stu Secure bottom of unit with two 16ga"L"brackets with No. 10 self-tapping 1/2" for screws to air handler and use 5/1s"lag screws 11/2"long to floor. B. If air handier is away from wall attach pipe strap to top of air handler using No. 1 1/2"long self-tapping screws on both sides.Angle strap down and away from bac 1 of air handler, remove all slack, and fasten to wall stud of structure using 5/16" IE screws 11/2" long. Secure bottom of unit with two 16ga "L" brackets with No. 1 self-tapping screws to air handler and use 5/16"lag screws 11/2"long to floor.

In addition to exposure to the exterior of the cabinet, chemical contaminants inside the building that can be drawn into the unit from the return air grille and attack structural metal parts, electrical components and the IA,Mj- indoor coil, causing premature failure of the unit. If the unit is to be installed in an area ' where contaminants are likely to be a problem, special attention should be given to iso- late the unit and return grille from contaminants. 3.3 AUXILIARY OVERFLOW PAN In compliance with recognized codes, an auxiliary overflow pan must installed under all equipment containing evaporator coils that are located in any area of a structure where damage to the building or building contents may occur as a result of an overflow of the coil drain pan or a stoppage in the primary condensate drain piping:See Section 6.3 of this manual for information regarding the recommended auxiliary horizontal overflow pan (model RXBM)for this air-handle. 3.4 CLEARANCES • All units are designed for"0" inches clearance to combustible material on all cabinet surfaces except for downf low application with higher kW electric heat as noted below. • Some units require a combustible floor base depending on the heating kW if installed in the downflow configuration on a combustible surface.The-following table should be used to determine these requirements. Model Cabinet Size 1 17 1 21 1 24 Maximum Model Designation kW 1 15 1 18 1 20 • Units with electric heating kW equal to or less than the values listed in the table do not require a combustible floor base.See Section 6.5 for Combustible Floor Base RXHB-XX. Units with electric heat require a one inch clearance to combustible material for the first three feet of supply plenum and ductwork. • Vertical downflow applications require clearance on at least one side of the'unit for electrical connections. Refrigerant and condensate drain connections are made on the front of the unit. • All units'require 24 inches minimum access to the front of the unit for service. • These units may be installed in either ventilated or nonventilated spaces. 3.5 DUCT FLANGES Duct flanges(4 pieces)are shipped with the unit and are to be field installed on the top of the air-handler using the following procedure and referring to Figure 9. 1. Loosen the screws attaching the heat barrier to the cabinet. 2. Form a"900 bend with the short leg length at approximately 9.9"from the end where the slot is cut in the flange to facilitate bending.The duct flanges are shipped sized for the 24.5" wide cabinet. For the 17.5" and 21" wide cabinets, cut the long leg as shown in Figure 9 to match the cabinet width. 3..Side the duct flanges onto the screws loosened in step one above. Tighten the. screws to secure the flanges.. FIGURE 9 DUCT FLANGE INSTALLATION! 21•CABINET CUT HERE 17"CABINET CUT HERE DUCT FLANGE i (2)REQUIRED NEAT BARRIER BEND." Y C:) .. 4Q lie 17 3.6 DUCTWORK Field ductwork must comply with the National Fire Protection Association NFPA NFPA 90B and any applicable local ordinance. WARNING Do not, under any circumstances, connect return ductwork to any othe heat producing device such as fireplace insert, stove, etc. Unauthorize use of such devices may result in fire, carbon monoxide poisoning,explc sion, personal injury or property damage. Sheet metal ductwork run in unconditioned spaces must be insulated and covered wi vapor barrier. Fibrous ductwork may be used if constructed and installed in accorda with SMACNA Construction Standard on Fibrous Glass Ducts. Ductwork must con with National Fire Protection Association as tested by U/L Standard 181 for Class I Ducts.Check local codes for requirements on ductwork and insulation. • Duct system must be designed within the range of external static pressure the un designed to operate against. It is important that the system airflow be adequate. M sure supply and return ductwork, grills, filters, accessories, etc. are accounted fc total resistance. Refer to the airflow performance tables in this manual to determine available external static pressure for the particular air-handler model being installed. • Design the duct system in accordance with"ACOA"Manual"D"Design for Resider Winter and Summer Air Conditioning and Equipment Selection. Latest editions available from: "ACCA"Air Conditioning Contractors of America, 1513 16th Str N.W.,Washington, D.C. 20036. If duct system incorporates flexible air duct, be pressure drop information (straight length plus all turns) shown in "ACCA" Mar "D"is accounted for in system. • Supply plenum is attached to the duct flanges supplied with the unit. See Section • IMPORTANT: If an elbow is included in the plenum close to the unit, it must not ' smaller than the dimensions of the supply duct flange on the unit. • IMPORTANT. The front flange on the return duct if connected.to the blower ca; must not be screwed into the area where the power wiring is located. Drills or sl- screw Fscrew points can damage insulation on wires located inside unit. • Secure the supply and return ductwork to the unit flanges,using proper fasteners for type of duct used and tape or caulk the duct-to-unit joint as required to prevent air le-, 3.7 RETURN AIR FILTER An internal filter rack is not provided with this air-handler. Therefore, an external me of filtering the return air is required. External filters should be sized for a maximun 300 feet/min air velocity or the maximum velocity recommended by the type of.f installed. One or more return air filter grilles, a filter rack attached to unit return intake, or a filter rack installed between a sealed return air platform and the return c are all acceptable means of filtration. All return ducts must be filtered, either at e return grille or at a common filter near the unit. Important: Do not install a return air filter grille and a filter rack at the unit and do install a filter in the supply duct system. Filter type,sizing,and placement are critical to heating and cooling system performar Reduced air-flow can shorten the life of system components such as the compres indoor coil, heater elements, over limits, and relays.As filters near the of their useful life, the pressure drop through them increases. Therefore, it is import to factor the"end of life"(dirty)pressure drop of filters into the external static pressun the duct system when selecting blower speeds and designing ductwork to assure system is operating at the design CFM and system reliability is not compromis Always verify that the system's air-flow is within specifications by performing a temp( ture rise(heating mode) and/or temperature drop(cooling mode)with all filters in plat Important: High efficiency pleated filters and electronic air cleaners typically have nificantly higher pressure drop than standard efficiency fiberglass filters,especially wl they get dirty. Do not use high efficiency filters or electronic air cleaners unless a quate filter area is provided to lower the filter pressure drop to an acceptablelevel. A WARNING Do not.operate the system without filters.A portion of the dust entrained in th air may temporarily lodge in the duct runs and at the supply registers.Any ci culated dust particles could be heated and charred by contact with the heatin elements. This residue could soil ceilings, walls, drapes, carpets and oth( articles in the house. Operating the system without a filter will also allow lir and dirt particles to accumulate on the indoor coil fin and restrict air-flo through the coil. Soot damage may occur even with filters in place when ce tain types of candles,oil lamps or standing pilots are burned. 18 3.8 ORIFICE SIZE The piston model air handier comes standard with a flow check piston installed.The pis- ton may need to be changed to a different orifice size depending upon the outdoor unit. The following table lists the recommended orifice size for various outdoor units: *Piston size installed at factory. Correct piston for other tonnages will be included with the matching outdoor unit. Indoor Nominal Tons Refrigerant Piston 2417 1'/2 Ton R-41 OA .049 2 Ton .057* 1/2 3617 23 Ton R-41 OA .062 .067* 4821 T3i4 Tonn R-41 OA :��$ 3.9 REFRIGERANT LINE CONNECTIONS & CHARGING 3.9.1 PREPARATION The coil is shipped with a low pressure (5-10 psig) charge of dry nitrogen which will be released when the rubber plugs are removed. Leave the rubber plugs in the refrigerant con- nection stubs on the air-handler until the refrigerant lines are ready to be brazed to the refrig- erant connection stubs to prevent contaminants from entering the coil. Clean the ends of the tubing and coil connection stubs(inside and outside)with an alcohol wipe before insert- ing the line set tubes into the coil connection stubs to assure a quality leak-free braze joint. Refer to the outdoor unit installation instructions for details on refrigerant line sizing and installation. Be sure to follow long line length guidelines if they apply. Route the refrigerant tubing in a manner than does not block service access to the front of the air-handler. 3.9.2 LIQUID LINE FILTER DRIER A new liquid filter drier must be installed every time any part of the system has been open to the atmosphere, even if it's for a short period of time. The filter drier should be installed close to the air-handler for a system started up in the cooling mode and near the outdoor unit for a heat pump system started up in the heating mode. This allows the filter drier to catch any contaminants in the liquid line before they can enter the indoor or outdoor TXV inlet screen. 3.9.3 BRAZING Air inside the tubing and coil should be displaced with dry nitrogen prior to the brazing process to prevent the formation of harmful copper oxide inside the tubing. It is very important not to pressurize the system with nitrogen while brazing or pin-hole leaks will form in the braze joint.This is accomplished by removing the gauge port valve core on one of the outdoor unit service valves to allow the pressure to be relieved as the heated nitrogen expands. Fill the system with dry nitrogen through the other service valve gauge port and then turn the nitrogen flow off dust before brazing is begun. Protect the TXV, copper to aluminum suction header joint,.and outdoor unit service valves from overheating using a wet rag or heat sink compound. Leave the wet rag or heat sink material in place until the joint and surrounding tubing cools down to a safe temperature. Double tip torches can help minimize brazing time and heat conduction to the heat sensitive components if the flame is turned down and held on the joint just long enough to make the braze joint. With both single and double tip torches, turning the flame up too much and keeping the flame on the joint too long will damage the heat sen- sitive components even when a wet rag or heat sink compound is used. Use a sheet metal shield to protect the cabinet's paint from the torch flames during the braz- ing process. The vapor line insulation should be pushed back on the line about 12 inches from the joint and retained to prevent it from igniting or melting during the brazing process. After the refrigerant brazed connections are made at the air-handier and the tubing has cooled down sufficiently, replace the coil section access panel if it has been removed and seal the air gap around the connection stubs with the foam rubber gasket included in the air-handler parts bag. Peel the self-adhesive backing off of the foam gasket and position it around the stubs with the adhesive side toward the cabinet,then press it firm- ly against the cabinet. The gasket is split to allow it to go over the stubs after the refrig- erant tubes are brazed to the stubs. (See Figure 11 in Section 3.10) After the foam gasket has been installed,the vapor line insulation should be pulled back in place so it contacts the air-handier cabinet to prevent condensate from form'ng on the cold tube and dripping off. A loosely fitting zip-tie placed around the insulation 1/2"from the end can be used to hold it in place so it doesn't move away from the cabinet. For air- °� handlers with TXV's, a section of the insulation will need to be cut out to make room for the externally mounted TXV bulb. (See Section 3.10) Once the bulb is mounted, insu- late the bulb with the foam insulation included in the air-handler parts bag, making sure none of the vapor line is uninsulated. 19 3.9.4 LEAK TESTING After all braze joints are completed, replace the valve core removed when purging w nitrogen and then leak test the system by pressurizing to 150 psig with dry nitrogen a allow the system to sit for at least 15 minutes (longer if possible) to assure the pressL does not drop. 3.9.5 EVACUATION If no leaks are detected, evacuate the system down to 500 microns or below befc charging the system or opening the service valves on the outdoor unit which will relea the charge stored in the outdoor unit into the line set and air-handler coil. Failure reach 500 microns of vacuum is a sign of a leak or excessive moisture inside the systel 3.9.6 REFRIGERANT CHARGING Once the evacuation process is completed, break the vacuum with the refrigerant from refrigerant cylinder or with refrigerant stored in the outdoor unit by opening the outdo unit service valves. The charging process cannot be completed until the remainil steps in the installation process are completed and the indoor air-flow is adjusted to tl proper level. See Section 4.7 for further details. 3.10 TXV SENSING BULB ATTACHMENT IMPORTANT: DO NOT perform any brazing with the TXV bulb attached to the vap line. After brazing operations have been completed and the tubing has cooled to tl touch, clamp the TXV.bulb securely on the vapor line at the 10 to 2 o'clock position (SE Figures 10 and 11) with the strap provided in the parts bag. Insulate the TXV sensir bulb and suction line with the provided pressure sensitive insulation (size 4"x 7") ar secure with provided wire ties. IMPORTANT: TXV sensing bulb should be located on a horizontal section of sup tion line,just outside of coil box. The copper sensing bulb must never be place on any aluminum tube as this will result in galvanic corrosion and eventualfailul of the aluminum tube. FIGURE 10 BULB LOCATION 10 O'CLOCK 2 O'CLOCK TXV TXV BULB BULB VAPOR LINE 3.11 CONDENSATE DRAIN Consult local codes or ordinances for specific requirements. IMPORTANT:When making drain fitting connections to the drain pan, use a thin layer o Teflon paste,silicone or Teflon tape and install hand tight. IMPORTANT: When making drain fitting connections to drain pan, do not overtighten Overtightening fittings can split pipe connections on the drain pan. • Install drain lines so they do not block service access to front of the unit. Minimurr clearance of 24 inches is required for filter,coil or blower removal and service access. • Although the condensate drain pan is designed is designed to be self draining, it is recommended that the air-handler cabinet be pitched slightly downward toward the pri. mary drain connection to assure the condensate drains completely from the drain pan The downward pitch should be approximately 1/8"per foot and in both axes. 20 FIGURE 11 TXV BULB&FOAM GASKET LOCATION FOAM GASKET TXV BULB ST-A1278-01 FIGURE 12 CONDENSATE DRAIN TRAP 3.000,MIN. 3.000 MIN. ST-A1244-01-01 • Do not reduce drain line size less than connection size provided on condensate drain pan. • All drain lines must be pitched downward away from the unit a minimum of 1/8" per foot of line to ensure proper drainage. • Do not connect condensate drain line to a closed or open sewer pipe. Run conden- sate to an open drain or outdoors. • The drain line should be insulated where necessary to prevent sweating and damage due to condensate forming on the outside surface of the line. • Make provisions for disconnecting and cleaning of the primary drain line should it become necessary. Install a 3 in. trap in the primary drain line as close to the unit as possible. Make sure that the top of the trap is below connection to the drain pan to allow complete drainage of pan(See Figure 12). • The auxiliary drain line should be run to a place where it will be noticeable if it becomes operational. The building occupant should be warned that a problem exists if water should begin running from the auxiliary drain line.An.auxiliary drain shut-off switch can be installed in lieu of an auxiliary drain line.The shut-off switch should be wired into the control circuit so the outdoor unit shuts down should the switch detect water. • Plug the unused drain connection with the plugs provided in the parts bag, using a thin layer of teflon paste,silicone or teflon tape to form a water tight seal. • Test the condensate drain pan and drain line after installation is complete. Pour water into drain pan, enough to fill drain trap and line. Check to make sure drain pan is draining completely, no leaks are found in drain line fittings, and water is draining from the open end of the primary drain line. 21 3.12 THERMOSTAT See instructions for the condensing unit or heat pump for recommended room thermostats. • On units with one electric heat sequencer (TDi) (see wiring diagram for electric heater), heat anticipator setting should be.16. • On units with two electric heat sequencers (TDi &TD2) (see wiring diagram for ele tric heater), heat anticipator setting should be.32 if both are connected to same sta on thermostat. Setting should be .16 if(TDi &TD2)are connected to separate stages. NOTE: Some thermostats contain a fixed, non-adjustable heat anticipator.Adjustment is not permitted. • The thermostat should be mounted 4 to 5 feet above the floor on an inside wall of the living room or a hallway that has good air circulation from the other rooms being con- trolled by the thermostat. It is essential that there be free air circulation at the location of the same average temperature as other rooms being controlled. Movement of air should not be obstructed by furniture, doors, draperies, etc. The thermostat should not be mounted where it will be affected by drafts, hot or cold water pipes or air ducts in walls, radiant heat from fireplace, lamps, the sun, T.V. or an outside wall. See instruction sheet packaged with thermostat for mounting and installation instructions. 3.13 ELECTRICAL WIRING Field wiring must comply with the National Electric Code (C.E.C. in Canada) and any applicable local ordinance. 3.13.1 CONFIGURING UNIT FOR 208 VOLT POWER The control transformer in 208/240V air-handlers must be configured in the field to oper- ate on a 208 volt electrical supply to assure adequate control voltage (24+volts)with the reduced supply voltage. The units are shipped from the factory for 220-240 volt applica- tions. For 208 volt applications, disconnect electrical power to the unit and remove the blower access panel and then the control box cover-located on the blower housing. Then remove the insulated cap from the 208 volt transformer terminal and move the BLACK wires that are connected to the 240 volt transformer terminal to the 208 volt transformer terminal. Plug the insulated cap onto the transformer 240V terminal. The indoor blower motor in 208/240V versions of the (-)HIP air-handlers must also be configured for 208 volt applications to assure full air-flow delivery at the reduced voltage. This step is not required on (-)HIT air-handlers since they have constant torque ECM motors. To configure the PSC motor in (-)HIP air-handlers for 208 volt applications unplug the PURPLE motor lead connected to the insulated terminal on the end of t. ORANGE wire coming from the transformer. Pull the cap out of the insulated terminal o end of the YELLOW motor lead and plug the cap into the terminal on the end of the PURPLE motor lead to eliminate the possibility of an electrical short. Plug the YELLOW motor lead into the terminal on the end of the ORANGE wire from the transformer. Secure the indoor blower motor wiring with zip ties to assure they can't come in contact with the blower wheel. Replace the control box cover and blower access panel. 3.13.2 GROUNDING • This product must be sufficiently grounded in accordance with National Electrical Code(C.E.C. in Canada)and any applicable local ordinance. j ® WARNING The unit must be permanently grounded. Failure to do so can result in electri- cal shock causing personal injury or death. • Grounding may be accomplished by grounding metal conduit when installed in accor- dance with electrical codes to the unit cabinet. • Grounding may also be accomplished by attaching ground wire(s) to ground lugs) provided in the unit wiring compartment. • Ground lug(s) are located close to wire entrance on left side of unit (upflow). Lug(s) may be moved to marked locations near wire entrance on right side of unit(upflow), if alternate location is more convenient. • Use of multiple supply circuits require grounding of each circuit to lug(s)provided in unit. 3.13.3 POWER WIRING It is important that proper electrical power is available for connection to the'unit model being installed.

National Electric Code (Section 424-22b) and UL standards allow subdividing heating element circuits, of less than 48 amps, using breakers of not more than 60 amps.Additionally per NEC 424-3b, a rat- ing not less than 125 percent of the load and NEC 424-22c, which describes the supplementary overcurrent protection required to be factory-installed within, or on the heater. The breakers in the heater kit are not, and have never been intended to protect power wiring leading to the air handler unit. The breakers in the heating Wit are for short circuit protection and to provide a disconnect. All internal unit wiring, where the breakers apply, has been UL approved for short circuit protection. i Am p Y acit , (not breaker size), determines supply circuit wire size. The ampacity listed on the unit rating plate and the Maximum and Minimum circuit breaker size (noted above) or in the units specification sheet or installation instructions provides the information to properly select wire and circuit breaker/protector size. The National Electric Code (NEC) specifies that the supply or branch circuit must be protected at the source. 30 3.13.8 CONTROL WIRING IMPORTANT- Class 2 low voltage control wire should not be run in conduit with power wiring and must be separated from power wiring, unless class 1 wire of proper voltage rating is used. • Low voltage control wiring should be 18 Awg. color-coded. For lengths longer than 100 ft., 16 Awg.wire should be used. j • Low voltage control connections are made to low voltage pigtails extending from top of air handler (upflow position - see Figure 3). Connections for control wiring are made with wire nuts. Control wiring knockouts (5/8 and 7/8) are also provided on the right and left side of the unit for side connection. • See Section 3.13.9 below for control wiring connections. • Make sure, after installation, separation of control wiring and power wiring has been maintained. • See Section 3.13.1 for how to reconfigure transformer for 208 volt applications. 3.13.9 THERMOSTAT&CONTROL WIRING CONNECTIONS i NOTE:These low voltage application diagrams are generic.Your WIRE COLOR CODE: indoor/outdoor units may not have all the characteristics shown or may BK-BLACK G-GREEN P-PINK W-WHITE not wire exactly as shown.Refer to the diagrams and information sent BR-BROWN GY-GRAY PR-PURPLE Y-YELLOW with your indoor/outdoor sections.

The (-)HIP and (-)HIT air-handlers must be configured in the field to assure proper air- flow is delivered for the particular application it is being used in. Refer to the AIR-FLOW PERFORMANCE DATA in Section 3.14.3 to determine which speed tap is appropriate for the application. Important: The pressure drop through the required external filter is not included in the external static pressure shown in the Air-Flow Performance Tables in Section 3.14.3. The filter pressure drop must•be added to the duct system pres- sure drop to determine total external static pressure. Filter pressure drop increas- es as the filter becomes dirty and must be considered when calculating worst case external static pressure. 3.14.2.1 (-)H1 P MODELS (PSC MOTOR) (-)HIP models are designed to be matched to a specific capacity outdoor unit, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, or 5.0 tons. They have PSC motors with 2 blower motor speed taps, low speed for applications with an external static pressure of up to 0.5" W.C. and high speed for applications with an external static pressure above 0.5"W.C. All models are shipped from the factory wired for high speed operation. Note: The external filter.pres- sure drop must be included in the external static pressure when selecting a blower motor speed. 115V &2081240V Models: The speed selection is made on the Blower Control Board. To change from high speed to low speed, remove the BLACK motor lead from the COM terminal, remove insulated cap from the end of the RED motor lead located in the control box and plug it into the terminal on the end of the BLACK motor lead to prevent it from shorting to ground. Attach RED wire to the COM terminal on the Blower Control Board. 480V Models: The speed selection is made on the Blower Relay. To change from high speed to low speed, remove the BLACK motor lead from terminal 3 on the Blower Relay and remove the cap from the terminal on the end of the RED motor lead. Connect the RED motor lead to terminal 3 on the Blower Relay. For 3-4 ton models only, connect the BLACK and YELLOW motor leads together. Note: There is no YELLOW motor lead on 5 ton models, so plug the cap that was removed from the RED motor lead into the terminal on the end of the BLACK motor lead to prevent it from shorting to ground. s 3.14.2.2 (-)HIT MODELS (CONSTANT TORQUE ECM MOTOR) Each (-)HIT model can be matched with 2 different outdoor unit capacities, 1.5 - 2.0 tons, 2.5 - 3.0 tons, 3.5 - 4.0 tons, & 4.0 - 5.0 tons depending on the model. (-)HIT Y models have constant torque ECM motors with 5 blower motor speed taps, labeled T1 through T5. Speed selections are made on a terminal block located on the motor hous- ing. Speed tap T1 is always dedicated to continuous fan operation and delivers approxi- mately 50%of the speed tap T4 air-flow. Speed taps T2&T4 are for applications with an external static pressure up to 0.5"W.C. (speed tap T2 for lower tonnage&speed tap T4 for higher tonnage). Speed taps T3 &T5 are for applications with an external static pressure above 0.5" W.C. (speed tap T3 for lower tonnage & speed tap T5 for higher tonnage). All models are shipped from the factory with speed tap T5 selected except for the (-)HiT4824S which is shipped with speed tap T3 selected. For optimum perfor- mance, efficiency, dehumidification, and the lowest possible noise level, select the appropriate speed tap for the specific application at the time of installation. Note: The external filter pressure drop must be included in the external static pressure when selecting a blower motor speed. To change the indoor blower speed on (-)HIT air-handlers, move the BLUE wire con- nected to terminal T5 (or T3 on (-)HiT4824S) located on the motor housing to the appropriate terminal(T2—T5)on the same terminal block. 32 3.14.3.1 240V AIRFLOW PERFORMANCE DATA: (-)HlP (PSG MOTOR) Ot �p MH CFM 681[321] 636[300] 606[286] 567[268] 523[247] — 10x6 Low RPM 541 601 670 714 768 1817ST High 523[705 CFM 1/5HP[149] Watts 193 181 173 164 157 No heater 240 V [247/333 US] 2 Speed CFM — 705[333] 650[307] 599[283] High RPM — 815 861 989 Watts — 239 227 204 CFM 651[307] 606[286] 576[272] 537[253] 493[233] — — 1817ST 1 OxIS Low RPM 571 631 700 744 798 — — with High 493/655 CFM 1/5HP(l 49] Watts 184 172 164 155 148 — I — 13kw heater 240 V [233/309 Us] 2 Speed CFM — 655[309] 600[283] 549[259] High RPM — 840 886 1014 Watts — 228 216 193 CFM 875[413] 806[380] 787[371] 739[349] 682[322] — — 10x6 1Ox6 Low RPM 648 700 745 794 827 — — 2417ST High 682/897 CFM 115HP[1491 Watts 259 255 243 234 227 . — — No heater 240 V [322/423 Us] 2 Speed CFM — 897[423] 851[402] 765[361] High RPM — 906 925 955 Watts — 332 318 306 CFM 845[399] 776[366] 757[357] 70913351 652[308] — — 2417ST 1 0x6 Low RPM 678 730 775 824 857 — — with High 652/847 CFM 1/5HP[l 49] — Watts 250 246 234 225 218 — — 13kw heater 240 V [308/400 Us] 2 Speed CFM — — — — 847[400] 801[378] 715[337] High RPM — — — — 931 950 980 Watts — — — — 321 307 295 CFM 1038[490] 1010[477] 976[461] 925[437] 883[417] — — 10x8 1Ox8 LOW RPM 721 771 799 848 — 880 - — — 3017ST High 883/1015 CFM 1/4HP[186] Watts 325 314 303 290 286 — — No heater 240 V [417/479 Us] 2 Speed CFM — 1015[479] 963[454] 890[420] High RPM — 928 955 974 Watts — 356 341 329 CFM 988[466] 960[453] 926 1437] 875[413] 833[393] 3017ST 1 Ox8 Low RPM. 771 821 849 898 930 — — with High 833/915 CFM 1/4HP[I 86] Watts 305 294 283 270 266 — — 18kw heater 240 V [393/432 Us] 2 Speed CFM — 915[432] 863[407] 790[373] High RPM — 953 980 999 Watts — 326 311 299 CFM 1229[580] 1201[567] 1170[552] 1141[538] 1104[521] — — 10x8 1OX8 LOW RPM 788 833 872 909 951 — — — 3617ST/-3621 ST High 1104/1194 CFM 1/3HP12491 Watts 466 — 462 427 - 406 395 — — No heater 240 V [521/563 Us] 2 Speed CFM — 1248[589] 1194[563] 1133[535] High RPM — 1008 1028 1042 Waft — 488 475 454 CFM 1179[556] 1151[543] 1120[529] 1091[515] 1054[497] LOW RPM 838 883 922 959 1001 3617ST/3621ST High 1054/1094 CFM 1 Ox8 Watts 446 442 407 386 375 — with 240 V [497/516 Us] 1/3HP[249] CFM — — — — 1148[542] 1094[516] 1033[487] 18kw heater 2 Speed High RPM — — 1033 1053 1067 Watts — — 458 445 424 CFM 1526[720] 1474[696] 1427[673] 1307[617] 1241[586] — — Low RPM 834 870 902 948 968 — — 4221ST High 1211/1514 CFM 1OXIO Watts 560 549 535 476 462 — — — No heater 240 V [5711714 Us] 1/2HP[373] — CFM — — — — 1537[725] 1418[669] 1334[630] 2 Speed High RPM — — — — 1072 1077 , 1085 Watts — — — — 860 835 820 CFM 1456[687] 1404[663] 1357[640] 1237[584] 1171[553] — — 4221ST loxio Low RPM 886 906 925 959 992 — — High 1225/1500 CFM Watts 542 524 505 468 431 — — with 1/2HP[373] 20kw heater 240 V [538/667 Us] 2 Speed CFM — — — 1437[678] 1318[622] 1234[582] High RPM — — 1080 1 1090 1 1105 t 33 3.14.3.1 24OV AIRFLOW PERFORMANCE DATA: (-)H1 P (PSC MOTOR) - continued , ' a ` �. at townSiza/ y :yif sryELM _ �;

O NO start-upRefer to outdoor unit installation instructions for system instructions and refrigerant charging instructions. 4.2 SYSTEM START-UP AND OPERATIONAL CHECK-OUT After the air-handler and other system components have been installed and the Pre-Start Checklist has been completed,the system should be started up and an operational check- out should be performed.The operational check-out includes checking sequence of opera- tion of the controls, air-flow,and refrigerant charge. If the controls are not found to be func- tioning properly,or the air-flow or refrigerant charge are not within specifications,corrective action must be taken. The following sections are provided to assist the installer with the operational check-out. ' 4.3 SEQUENCE OF OPERATION 4.3.1 COOLING MODE When the thermostat calls for cooling, the G terminal on the blower control board is 9 energized which in turn energizes the indoor blower motor.This causes the indoor blow- er . er to circulate air through the air-handler and duct system during the cooling cycle. For $ (-)HIT air-handlers, the Y terminal on the blower control board is also energized which tells the blower control board to energize the cooling speed on the motor instead of the reduced CFM continuous fan speed. When the thermostat call is satisfied or the thermostat is turned to the off position.The G and Y terminals on the blower control board are de-energized.A time delay programmed into the (-)HIP blower control board or(-)HIT motor keeps the blower motor energized " for an additional 30 seconds to extract the residual cooling from the cold indoor coil. y 4.3.2 ELECTRIC HEAT MODE When the thermostat calls for the 1 st stage of heat;the W1 terminal on the blower con- trol board is energized. This energizes the indoor blower motor and all of the electric heater elements for heater kits with 10kW of heat or less and the 1 st stage elements for n... 13kW heater kits and higher. If W1 and W2 thermostat pigtails at the air-handler are wired together on 13kW heater kits and higher, all of the elements to be energized. For 13kW heater kits and higher, a 2-stage heat thermostat can be used to energize the W2 fi. 41 terminal on the blower control board upon a call for a 2nd stage of heat which will in turn will energize the 2nd stage heater elements. The heater kit will cycle between the 1st and 2nd stages of heat at the direction of the thermostat. When the thermostat call for heat is satisfied or the thermostat is turned to the off posi- tion, the W1 terminal on the blower control board is de-energized which will de-energize the heating elements in a few seconds as the bimetallic disc in the sequencer cools.The blower motor will be de-energized 75 seconds after the call for heat ends. 4.3.3 HEAT PUMP HEATING MODE When the heat pump thermostat is set to "heat" mode, the `B"terminal on the outdoor unit is energized which energizes the reversing valve and switches it to the heating posi- tion. When the thermostat calls for heat, the G terminal on the blower control board is energized which in turn energizes the indoor blower motor.This causes the indoor blow- er to circulate air through the air-handler and duct system during the heating cycle. For (-)H1T air-handlers, the Y terminal on the blower control board is also energized which tells the blower CFM continuoustrol speed.ard to heating gize the speedd on the motoeed on the rs is or instead of the rethe same as the cooling speed. Should the room temperature continue to fall when the system is operating in the heat pump heating mode, the thermostat energizes the W2 terminal on the blower control board which energizes supplemental electric heat. For 13kW heater kits and larger,the W1 and W2 pigtails can be connected together for maximum supplemental heat for 2nd stage or wired to the W1 and W2 terminals on the thermostat separately to provide a 3rd stage of heat as needed. When the thermostat call for heat is satisfied,the G and Y terminals on the blower con- trol board are de-energized. A time delay programmed into the (-)H1 P blower control board or(-)H1T motor keeps the blower motor energized for an additional 30 seconds to extract the residual heat from the warm indoor coil. 4.3.4 SUPPLEMENTAL ELECTRIC HEAT DURING DEFROST Supplemental electric heat during the defrost cycle can be provided by running a wire from the purple pigtail wire (from D terminal on defrost control) on the outdoor heat pump unit to the W1 pigtail on the air-handler.This will energize the electric heat during the defrost cycle to prevent cold air from being discharged from the supply registers in the home. For the most economical operation and if cold discharge air is not a concern, do not run the wire from the purple pigtail on the outdoor unit to the W1 pigtail on the air-handler. In this case, supplemental heat will only be energized if the thermostat energizes the 2nd stage of heat during the defrost cycle due to a significant drop in room temperature. t 4.3.5 EMERGENCY HEAT (HEAT PUMP) If heat pump thermostat is set to the "Emergency Heat' mode, the outdoor unit will be prevented from operating and heat will be provided solely by the electric heater. The electric heater elements and indoor blower.motor will be energized any time there is a call for heat with no compressor and outdoor fan operation. A jumper should be installed between the W1 and E terminals on the thermostat sub-base so a call for emer- gency heat will be transferred to the 1st stage of heat of the thermostat. The indoor blower will cycle on and off with the electric heater elements when the thermostat fan setting is set to the"auto"mode, although there will be a 75 second delay off period for the blower motor after the call for heat ends. 4.3.6 THERMOSTAT FAN SETTING If the thermostat "FAM' setting is adjusted to the "AUTO" position, the indoor blower motor will only operate when there is a call for cooling or heating. If the setting is adjusted to the "ON" position, the indoor blower motor will operate continuously. On (-)H1T models, the indoor blower motor will operate at a reduced speed when there is no call for cooling and heating to reduce power consumption and noise. 4.4 CORRECTING ELECTRIC HEAT kW FOR VOLTAGE The actual electric heat kW varies with the supply voltage. Use the following formula to correct the heater rated kW at voltages other than rated voltage. Actual kW= Rated kW x (Actual Voltage2 / Rated Voltage2). 4.5 CALCULATING ELECTRIC HEAT CAPACITY IN BTU Use the following formula to convert heater kW to heating capacity in BTUH. BTUH Capacity=kW x 3412 I (Where 3412=BTUH per kW) i 42 4.6 CHECKING INDOOR AIR-FLOW 4.6.1 ESTIMATING CFM USING EXTERNAL STATIC PRESSURE A common method of checking indoor is to measure the external static pressure that the__ air-handler is working against and then referring to the air-flow data in Section 3.13.r Measuring external static pressure to a high degree of precision in the field is challen, ing, so keep in mind that the CFM determined by this method is an estimate, but is accu- rate enough for all practical purposes. To determine external static pressure, the static pressure should be measured in inches of water column across the air-handler using an incline manometer, digital static pres- sure meter, or a Magnahelic. The static pressure inside the return plenum should be measured as close to the air-handler as possible and must be measured between any external filter rack and the unit so the pressure drop across the filter is accounted for. The static pressure inside the supply plenum should be measured at a point about halfway between the air-handler and the first elbow or the end of the plenum. Total external static pressure is the sum of the return and supply plenum static pressures. Even though the return plenum static pressure is a negative pressure, it must be added to the supply plenum static pressure, ignoring the negative sign. The supply and return plenum static pressure tubing can also be connected to both pressure ports of the pres- sure measuring device which will automatically add the two pressures together. y:.. 4.6.2 ESTIMATING CFM USING ELECTRIC HEAT TEMPERATURE RISE r If the air-handler is equipped with an electric heater, the CFM can be estimated using Fu: the air temperature rise across the air-handler with the heater and blower both ener- gized once the unit has run long enough for the temperatures to stabilize. As with �r determining CFM using external static pressure, the CFM determined by this method is an estimate, but is accurate enough for all practical purposes. Measure the return air ? ' temperature as close to the unit as possible and the supply air temperature about half way from the air-handler to the first elbow or end of the supply plenum. Use the follow- Ing formula to calculate CFM once the temperature rise is determined. CFM=Heating BTUH/(Elevation Factor x Temp Rise°F) • Note: Refer to Section 4.5 to determine Heating BTUH and the following chart for Elevation Factor. ' Elevation (Feet) Elevation Factor Sea Level 1.08 500 0.98 1000 0.96 1500 0.95 2000 0.93 2500 0.91 3000 0.90 3500 0.88 4000 0.86 5000 0.83 6000 0.83 7000 0.77 8000 0.74 9000 0.72 10000 0.69 4.7 CHECKING REFRIGERANT CHARGE System refrigerant charging should only be performed after the indoor air-flow is con- firmed to be correct for the application. Once the air-flow is confirmed, refer to the man- ufacturer's outdoor unit charging chart and installation manual for the proper charging ?: procedure for the system. Note: The charging method for systems with a fixed orifice (piston) will likely be differ- ent than systems with TXV's. J l v� 43 5.0 COMPONENTS & CONTROLS 5.1 BLOWER MOTOR All(-)H1 P models have 2-speed single-phase permanent split capacitor(PSC)style motors. • The 208/240 volt models also have voltage taps that allow the motor to be configured to restore full air-flow performance in 208 volt applications. • The low speed tap is for applications with duct system external static pressures up to 0.5" W.C. and the high speed tap is for applications with external static pressures from 0.5—0'.7"W.C. • A run capacitor is required for the PSC motors which is mounted on the blower hous- ing. Speed and voltage change instructions are detailed in Sections 3.13.1 &3.14.2 of this manual. All (-)HIT models have 5-speed constant torque electronically commutated (ECM) style motors that are significantly more efficient than PSC motors. • The 208/240 volt models do not require the motor to be reconfigured for 208 volt applications, although the control transformer must still be reconfigured for 208 volt applications. • The motor has a control module mounted on the end of the motor opposite the shaft end which is replaceable should only the control module itself fail. • Constant torque ECM motors do not require a run capacitor. • A terminal block on the motor shell is provided for the 5 speed taps, labeled Ti —T5. The speed taps are 24VAC inputs. Do not connect line voltage to these speed taps. T1 provides the slowest speed and is dedicated to continuous fan operation. T2—T5 are for cooling & heating operation and are selectable at the terminal block using a single wire with an insulated terminal that plugs onto the terminals in the ter- minal block. Speed change instructions are detailed in Section 3.14.2. • The constant torque motor has a built in soft start that will ramp the motor up to speed gradually. • An off-delay is built into the control of the motor that keeps the motor energized for 30 seconds after 24 volts is removed from all speed tap terminals. • If two of the speed tap terminals (T1 —T5) are energized with 24 volts simultaneously, the motor will operate at the higher of the 2 speeds. An example of this is when the G and Y thermostat inputs are both energized in the cooling or heat pump heating mode. In this case, T1 (continuous fan) and a higher numbered speed tap will both be energized resulting in the motor operating at the higher speed to support the cool- ing or heat pump heating air-flow requirement. • The air-flow delivery rate for a constant torque ECM motor will not decrease as much as it does with a PSC motor as external static pressure increases. 5.2 MOTOR RUN CAPACITOR Only the (-)HIP models have a run capacitors due to the fact they have PSC motors. The capacitor is mounted on the blower housing using a sheet metal strap. The micro- farad (mfd) &voltage ratings vary depending on the blower motor and must be replaced with one with the same rating, except 370V rated capacitors can always be replaced with a 440V rated capacitor. I , 5.3 BLOWER CONTROL l� An electronic blower control is provided to control blower motor&electric heat operation and is located inside the control box attached to the blower housing. The blower control I; in the(-)H1 P and(-)HlT operate differently as described below. i (-)Hi P Blower Control • The contacts in the on-board relay(BR) are used to connect line voltage to the motor speed tap when there is a call for motor operation. Motor speed changes are made by switching motor speed taps at this relay. • The control has an on-board 3 amp automotive style fuse to protect the control circuit. • A plug on the electric heater kit wiring harness plugs into a 4 pin plug receptacle on the blower control to allow control of the electric heater by the blower control based on thermostat input. d There is a 5-pin connector for the thermostat pigtail harness to connect to. Wires j I from the thermostat do not connect directly to the blower control, but rather to the pig- tails that are routed to the exterior of the air-handler cabinet. • There is a 2 second on-delay for blower operation when there is a call for blower operation. • There is a 30 second blower off-delay when a call for cooling or heat pump heating ends. • There is a 75 second blower off-delay when a call for electric heating ends. This t allows time for the contacts in the bi-metallic disc type heating sequencer to open which de-energizes the heater elements. �` 44 �Y (-)HIT Blower Control • There are two 24V outputs on the blower control for controlling the motor, one for con- tinuous fan and one for cooling&heating operation. • Motor speed changes are made at the motor speed terminal block instead of on the blower control. • The control has an on-board 3 amp automotive style fuse to protect the control circuit. • A plug on the electric heater kit wiring harness plugs into a 4 pin plug receptacle on the blower control to allow control of the electric heater by the blower control based on thermostat input. • There is a 6-pin connector for the thermostat pigtail harness to connect to. Wires from the thermostat do not connect directly to the blower control, but rather to the pig- tails that are routed to the exterior of the air-handler cabinet. • There is no on-delay for blower operation when there is a call for blower operation. • There is no blower off-delay provided by the blower control when a call for cooling or heat pump heating ends since a 30 second off-delay is programmed into the constant torque ECM motor. • There is a blower off-delay programmed into the blower control when a call for electric heating ends.The delay is 45 seconds for the White-Rodgers control and 30 seconds }3 for the UTEC control. This off-delay is added to the 30 second off delay programmed ` into the motor for a total off-delay of 75 or 60 seconds. This allows time for the con- "" tacts in the bi-metallic disc type heating sequencer to open which de-energizes the heater elements. 5.4 BLOWER The blower utilizes a forward curved centrifugal wheel.The blower housing is construct- ed from galvanized sheet metal. The motor is attached with a 4-arm belly band type mount that screws into the side of the blower housing. The control box attaches to the �,.;• front of the blower housing for assess through the blower access door. The blower slides into place on a track and is secured by 4 sheet metal screws. °1 5.5 TRANSFORMER A 40VA transformer is located inside the control box attached to the blower housing F which provides 24V control voltage for both the air-handler & the outdoor unit. The transformer in 208/240V models is wired from the factory for 240V applications, but has a separate 208V tap for 208V applications. The black wires connected to the 240V tap must be moved to the 208V tap when installing the air-handier in 208V applications to assure full 24V+control voltage for reliable operation of the system controls. 4k 5.6 INDOOR COIL ASSEMBLY • The indoor coil slabs are a fin&tube design with enhanced aluminum fins&internally grooved aluminum tubing. Most models have 3 coil slabs in an "N" configuration, but some models have 2 coil slabs in an"A"configuration. All (-)H1 P air-handlers have non-'bleed thermal expansion valves(TXV) for refrigerant control. (-)HIT air-handlers can have either a non-bleed TXV or a fixed orifice (piston). The orifice may have to be changed when the air-handler is matched to certain outdoor units. The correct orifice will be supplied with the outdoor unit in cases where the ori- fice requires changing. (See Section 3.8) • The 10th character in the model number indicates which type of metering device the air-handler is equipped with, "T"for TXV and "P"for piston. (See Section 2.3 for the model number nomenclature). All models have a self-draining polypropylene condensate drain pan to eliminate • standing water&a painted &insulated sheet metal drip pan to catch any water drips �. from the coil when the air-handler is oriented in the horizontal position. All models have built-in sheet metal channels in various locations designed to man- age condensate when the air-handler is oriented in the horizontal position, thus pre- ; .• venting water"blow-off". • Copper stubs are provided for field tubing connections. • The coil assembly slides into the air-handler on sheet metal rails. The coil is installed in the factory for upflow&horizontal left orientations. The coil must be removed and re- installed into the air-handler cabinet 1800 from its factory orientation.An additional set �`„• of coil support rails must be installed before the coil can be re-installed.The additional set of rails are included with the air-handier for field installation. (See Section 3.2.2) • The TXV sensing bulb is shipped unattached & must be securely attached to the vapor line with the supplied clamp and insulated with the supplied foam insulation. (See Section 3.10) t 45 6.0 ACCESSORIES & KITS 6.1 ELECTRIC RESISTANCE HEATER KITS • All (-)H1 P&(-)HIT models are shipped without electric resistance heat. • Electric heat kits ranging from 3kW to 30kW are available for field installation. • Refer to Sections 3.13.5, 3.13.6, & 3.13.7 for electric heat kit model numbers avail- able for specific air-handler models along with electrical ratings & additional informa- tion regarding the heater kits. • Heater kit installation instructions are provided with the heater kit. • All heater kits utilize open wire nickel chromium heating elements. • An automatic reset over-temperature limit is provided to shut off the heater elements should air-flow become too restricted or if the blower motor fails. • 13kW kits and larger are designed to operate in 2-8tage heat mode if so desired or can be operated as single stage if the W1 & W2 thermostat pigtails are wired together. • 208/240V single-phase ("J" Voltage), 208/240V 3-phase ("C" Voltage), & 480V 3- phase("D"Voltage)heater kits are available. • 115V("A"Voltage) heater kits are not available. • 208/240V 3-phase ("C" Voltage) heater kits must be installed in "J" Voltage air-han- dlers since there are no"C"Voltage air-handlers available. "C"voltage heater kits are for 3-phase applications and allow for smaller wire &fuse/breaker size compared to single-phase"J"Voltage heater kits. • The heater kit is controlled by the blower control based on thermostat inputs. • All heater kits are available with a circuit breaker style disconnect. • 1 OkW heater kits and smaller are also available with either a pull-out style disconnect or with no disconnect. • Incoming electric power is connected directly to the heater kit power terminals. • The heater kit is provided with 2 power wires that connect to the air-handler power terminal block, providing power to operate the blower motor and controls. • The heater kit is also provided with a 4-pin connector that plugs into a mating plug on the blower control to allow the control of the heater based on thermostat inputs. 6.2 JUMPER BAR KITS • Jumper Bar Kit 3 Ckt.to 1 Ckt.

Consult your local dealer as to the proper frequency of maintenance and the availability of a maintenance contract. a IMPORTANT: Before performing any service or maintenance procedures, see the 1 "Safety Information"(Section 1.0)at the front of this manual. A WARNING Units with circuit breaker(s) meet requirements as a service disconnect switch, however, if access is required to the line side (covered) of the circuit breaker, this side of the breaker(s) will be energized with the breaker(s) de- energized. Contact with the line side can cause electrical shock resulting in personal injury or death. 7.1 AIR FILTER Check the system filter every ninety days or as often as found to be necessary and if obstructed, clean or replace at once. A qualified installer, service agency or HVAC professional should instruct the homeown- er on how to access filters for regular maintenance. IMPORTANT:Do not operate the system without a filter in place. • New filters are available from a local distributor or home supply retailer. 7.2 INDOOR COIL, DRAIN PAN, DRAIN LINE Inspect the indoor coil, drain pan, and drain line once each year for cleanliness and clean as necessary. In some cases, it may be necessary to remove the filter and check the return side of the coil with a mirror and flashlight. IMPORTANT. Do not use caustic household drain cleaners, such as bleach, in the con- densate pan or near the indoor coil. Drain cleaners will quickly damage the indoor coil. 7.3 BLOWER MOTOR AND WHEEL Inspect the blower motor and wheel for cleanliness. It should be several years before it would become necessary to clean the blower motor and wheel. ' • If it becomes necessary to remove the blower assembly from the unit,see instructions on removal and replacement of motor,blower,and blower.wheel in Sections 7.5-7.7 below. • The blower motor and wheel may be cleaned by using a vacuum with a soft brush K attachment. Remove grease with a mild solvent such as hot water and detergent. Be careful not to disturb the balance weights (clips) on the blower wheel blades. Do not drop or bend wheel as balance will be affected. 7.4 MOTOR LUBRICATION The blower motor sleeve bearings are pre-lubricated-by the motor manufacturer and do not have oiling ports. Motor should operate for an indefinite period of time without addi- tional lubrication. I 7.5 BLOWER ASSEMBLY REMOVAL&REPLACEMENT Removing the blower assembly is not normally required for normal service and mainte- nance. Removal is necessary for replacement of defective parts such as motor, blower wheel.After extended use, removal of the blower assembly may become necessary for a thorough cleaning of the blower motor and wheel. Q WARNING If removal of the blower assembly is required, all disconnect switches supply-. Ing power to the equipment must be de-energized and locked (if not in sight of unit)so the field power wires can be safely removed from the blower assembly. Failure to do so can cause electrical shock resulting in personal injury or death. • Mark field power supply wiring (for replacement) attached to terminal block or circuit } breaker(s)on blower assembly.Remove wiring from terminal block or circuit breaker(s). r" Mark low voltage control wiring (for replacement) where attached to unit control pig- tails on right side of blower housing.
