TEST RUN

7. Test run

7.1. Before test run

After completing installation and the wiring and piping of the indoor and out- door 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 M .

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 M.
