● After installing, wiring, and piping the indoor and outdoor units, check for refrigerant leakage, looseness in power supply or
control wiring, and mistaken polarity.
● Use a 500-volt megohmmeter to check the resistance between the power supply terminal block and ground to make sure
that it is at least 1.0MΩ.
Attention:
Do not use the air conditioner if resistance is less than 1.0MΩ.

Measure an impedance between the power supply terminal block
on the outdoor unit and the ground with a 500 V Megger and
check that it is equal or greater than 1.0M
