Always lit

● During normal operation

The LED indicates the drive state of the controller in the outdoor unit.

●

When fault requiring inspection has occurred

　The LED alternately indicates the inspection code and the location of the unit in which

the fault has occurred.

NOTES:

1.Refer to the wiring diagrams of the indoor units for details on wiring of each indoor unit.

2.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.

• Use copper supply wires.

Cautions when servicing

Caution for electrical work

WARNING: When the main supply is turned off, the voltage [340 V] in the main capacitor will drop to 20 V in approx. 2

minutes (input voltage: 230 V). 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.
