10-2. 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 control

(3)Judgment of trouble by every symptom

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