Cautions when Servicing · !WARNING: When the main supply is turned off, the voltage [340 V] in the main capacitor will drop to 20 V in approx. When servicing, make sure that LED1, LED2 on the outdoor circuit board goes out, and then wait for at least 1 minute. · Components other than the outdoor board may be faulty: Check and take corrective action, referring to the service manual. Do not replace the outdoor board without checking. NOTES: 1. Refer to the wiring diagrams of the indoor units for details on wiring of each indoor unit. Self-diagnosis function The indoor and outdoor units can be diagnosed automatically using the self-diagnosis switch (SW1) and LED1, LED2 (LED indication) found on the multi-controller of the outdoor unit. LED indication : Set all contacts of SW1 to OFF.
