3.1.8.Before test run

After completing installation and the wiring and piping of the local application 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 1.0MΩ.
Warning:
Do not use the system if the insulation resistance is less than 1.0MΩ.
Caution:
Do not carry out this test on the control wiring (low voltage circuit) terminals.
