8.1. Before test run
s 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.
s Use a 500-volt megohmmeter to check that the resistance between the power
supply terminals and ground is at least 1.0MΩ.
