11-2. Primary Judgment

To diagnose the troubles, use the following methods.

(1)Judgment by flashing LED of indoor unit

(2)Self-diagnosis by service check remote controller

(3)Judgment of trouble by every symptom

Firstly use the method (1) for diagnosis. Then, use the method (2) or (3) to diagnose the details of troubles.

For any trouble occured at the outdoor unit side, detailed diagnosis is possible by 5-serial LED on the inverter P.C. board.
