After installation of indoor and outdoor units, and piping and electric wiring work, recheck that the unit is free from leaks of refrigerant, loosened connections, and incorrect polarity.

Measure an impedance between the power supply terminal block (L, N, ) on the units and the ground with a 500 V Megger and check that it is equal to or greater than 1.0 MΩ.

9.2.1. For wireless remote controller (Fig. 9-1)

Measure an impedance between the power supply terminal block on the outdoor unit and the ground with a 500 V Megger and check that it is equal to or greater than 1.0 MΩ.

• Before performing the test run, recheck for any wrong wiring. Wrong wiring prevents normal operation or results in blown fuse disabling operation.
