INSTALLING THE OUTDOOR UNIT

Auxiliary Circuit Breaker

Outdoor unit	Distribution
	board

Auxiliary power s/w

◆Auxiliary circuit breaker should be installed near outdoor unit so that each access is possible. Main/outdoor power supply cable are connected to upper/lower terminal of auxiliary circuit breaker.

◆It is necessary that the conduit kit for power supply to the outdoor unit be installed between auxiliary power S/W and the outdoor unit. (the conduit kit is optional)

❊The designs and shape are subject to change according to the model.

Electrical Work

1The supply voltage must be the same as the rated voltage of the air conditioner.

2Prepare the power souce for exclusive use with the air conditioner.

3Use 15 amperes time delay fuse or circuit breaker.
