TROUBLESHOOTING

6-1. Cautions on troubleshooting

(1) Before troubleshooting, check the followings:

1Check the power supply voltage.
2Check the indoor/outdoor connecting wire for mis-wiring.

(2) Take care the followings during servicing.

1 Before servicing the air conditioner, be sure to first turn off the remote controller to stop the main unit, and then turn

off the breaker.

2 When removing the indoor controller board, hold the edge of the board with care NOT to apply stress on the

components.

3 When connecting or disconnecting the connectors, hold the housing of the connector. DO NOT pull the lead wires.
