7.8.3 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 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.
