6.1. 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.
