2-5 Test run
<Before test run>
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 measure 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.
