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 sup-
ply 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 M .
7.2. Test run
Refer to the installation manual that comes with each remote controller for details.
7.3. Self-check
