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 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 MΩ.

►Do not carry out this test on the control wiring (low voltage circuit) termi- nals.

Warning:

Do not use the air conditioner if the insulation resistance is less than 1.0 MΩ.

7.2. Test run

Refer to the installation manual that comes with each remote controller for details.
