3.6.2 Tochecktheinsulationresistanceofthe
compressor
NOTICE
If, after installation, refrigerant accumulates in the
compressor, the insulation resistance over the poles can
drop,but ifitis atleast1 MΩ,thenthe unit willnotbreak
down.
▪ Usea500Vmegatesterwhenmeasuringinsulation.
▪ Donotuseamegatesterforlowvoltagecircuits.
1 Measuretheinsulationresistanceoverthepoles.
If Then
≥1MΩ InsulationresistanceisOK.Thisprocedure
isfinished.
<1MΩ InsulationresistanceisnotOK.Gotothe
nextstep.
2 TurnONthepowerandleaveitonfor6hours.
Result: The compressor will heat up and evaporate any
refrigerantinthecompressor.
3 Measuretheinsulationresistanceagain.
