7. Test run
7.1. Before test run
After completing installation and the wiring and piping of the indoor and
outdoor units, check for refrigerant leakage, looseness in the power
supply or control wiring, wrong polarity, and no disconnection of one
phase in the supply.
Use a 500-volt megohmmeter to check that the resistance between the
power supply terminals and ground is at least 1.0 MΩ.
Do not carry out this test on the control wiring (low voltage circuit)
terminals.
Warning:
Do not use the air conditioner if the insulation resistance is less than 1.0 MΩ.
Insulation resistance.
