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.
NOTICE
It is recommended that the refrigerant piping between indoor and outdoor unit is
installed in a ducting or the refrigerant piping is wrapped with finishing tape.
