10 Finishing the outdoor unit installation
10.1 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.
10.2 To finish the outdoor unit installation
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.
INFORMATION
For the requirements of the refrigerant piping insulation, see "8.1.2 Refrigerant
piping insulation"[491].
