Electrical Work

The electrical work should be performed by a specialist qualified for the work.

Use the single phase power supply, and be sure to install the sub power distributing board for exclusive use with the unit (separately purchased by the user).

※Avoid multiple connecting wiring as it can cause a drop in voltage, thus resulting in poor performance of the automatic control circuit.

Be sure to install circuit breaker (separately purchased by the user).Be sure to connect the grounding wire.

The indoor unit is powered by the outdoor unit by means of a H07 RN-F connection cable (or a more power model), with insulation in synthetic rubber and jacket in polychloroprene(neoprene), in accordance with the requirements of standard IEC 60335-2-40.

1.Remove the screw on the electrical component box and remove the cover plate.

2.Route the connection cord through the side of the indoor unit and connect the cable to terminals.

3.Route the other end of the cable to the outdoor unit through the ceiling & the hole on the wall.

4.Reassemble the electrical component box cover, carefully tightening the screw.
