installation
7.1 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.

INFORMATION
Cooling is only applicable in case of reversible models.
8.1 Overview: Configuration
This chapter describes what you have to do and know to configure
the system after it is installed.
NOTICE
This chapter explains only the basic configuration. For
