forgot to add these airwells have lg COMPS
Sounds like non-condensibles in the systems.
Sorry, forgot to ask, was the leak fixed and the unit vacced out again before recharge?
Hi thebigcheese,
I suggest that you put the unit in cooling mode and take all he readings. Then put it in heating mode then take the readings again.
LP , HP, SH , SC, Ait temp. in and out of the indoor unit, ambient temperature.
These can help to diagnose the fault.
Cheers:)
think i got it sorted there is a flow device fitted on the licquid line ithink for on heating, checked it today and there was some dirt in the inside if it , as for the other unit it only ever runs on heating so just left it alone
thanks for all the replys ps leaking from flare and blew through with nitro then vacced
