4.6.3 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
≥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.
