This pump has been specially ����``�. •�'� / designed by Grundfos• for 'BAX1. The 1 pump body incorporates an automatic air bleeder' for 'venting the air from the boiler.

Fig.55 If the installation, be it new or old has not been flushed correctly the debris, Pump Wiring oil and flux in the system will damage Cover.,' the rotor and barings in the pump. We v recommend that the system be flushed A before opening the shut off valves to the boiler; this will prevent debris from being pushed through the boiler. Then 15 run the boiler to maximum temperature, drain and flush again. This will remove any oil and flux remaining in the Fig.56 system. Luna 310 & 1.31 Flushing procedure The procedure'for flushing the closed loop is as follows:, • Connect a hoseto the system drain tap • Close the boiler heating supply valve (this will allow clean water to be flushed through the boilenfirst), •,O;pen the drain,tap on the•closed loop •.Open the fill valve on-the boiler (the blue handle under the boiler)] When you see clear vyater coming from the hose, close the fill valve •Now open the,b.oilex heating supply valve and close the return valve Open the fill valve on the boiler (this will flush'the rest of the system) • When you,see clear,water coming from the hose, close the fill valve •,Close;the,drain.tap and remove the hose • Pressurize the system to the correct pressure on the pressure gauge { BAXI LUNA ,310 Fi Ttouble shooting Guide Before getting started, remember... Most of the faults experienced on start up are field issues associated with items external to the boiler. These are mostly simple problems, such as: • Venting installed incorrectly • Air in the system (system must-be fully purged) • Air in the gas line • Undersized gas line _ • System not"flushed (cold flush then hot flush) i • Incorrect connecti6n'of external equipment • Leaks-in the Heating-system-and pipe-work All BAXI LUNA boilers are tested during manufacture'for-correct operation and are shipped to you factory tested for correct operation.' Notwithstanding, while commissioning the boiler, a few items need to be checked: • '-Inlet-gas pressure (static-arid working irileti pressure of boiler running-at ; maximum output) • Maximum and minimum burner pressures • . Power supply-for polarity,and=ground ; When troubleshooting BAXI LUNA boilers, avoid changing parts prematurely do not jump to the-conclusion that a,boiler,component is,defective. For example: • Parts '8uch as the control•PCB are changed incorrectly, when it is another component supplying false information to,it:, r� , 1- ! • The pump- is sometimes changed unnecessarily, because it has stopped operating. A pump operational fault is normally the result of contamination from a dirty hydroiiic system - iii Vhi6h case, the'pump can be removed and cleaned (after which"the heating system must be flushed and cleaned), and then returned to normal operation. Get all the information before going to,.the job site.............. Get as much information from your customer before you go to the boiler: model of boiler; type of.venting;-,type ,a ype of-system_ nd-layout connected to the-boiler; how-long has the system been ,,installed, and is this an.isolated breakdown or"are they repeatedly resetting the boiler? Don't be afraid to ask the obvious questions! Does your customer.know how to reset the boiler? , (Just unplugging the lead and replacing it, or turning the boiler off and on again will not reset the logic board.) They have to turn the switch to "R" to restart the boiler. Is there any water in the system? Where is the needle on the pressufe gauge? This may save-an unnecessary trip to the job site. - BAXI LUNA 310 Pi troubleshooting guide a 7 8 8 10 11 ° �I Ae®awi,(j 11 11 ,fY>, } 0 ` T oiie `�•iIIYA l�i 30° 40° 50° 60° 70° 80° A 8 8B @ \F a 1 2 3 4 5 Fig 1 ° e Neon Indicators " 6: Flame Failure + 7.
