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