Wiring

WARNING

1) Do not use tapped wires, stand wires, extensioncords, or starbust connections, as they may cause overheating, electrical shock, or fire.

2) Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc., from the

terminal block.) Doing so may cause electric shock or fire.

3) Be sure to install an earth leak detector. (One that can handle higher harmonics.)

(This unit uses an inverter, which means that it must be used an earth leak detector capable handling harmonics in order to

prevent malfunctioning of the earth leak detector itself.)

4) Use an all-pole disconnection type breaker with at least 3 mm between the contact point gaps.

• Do not turn ON the safety breaker until all work is completed.

1) Strip the insulation from the wire (20mm).

2) Connect the connection wires between the

indoor and outdoor units so that the terminal

numbers match. Tighten the terminal screws

securely. We recommend a flathead screw-

driver be used to tighten the screws. The

screws are packed with the terminal board.

3) Pull the wire and make sure that it does not disconnect. Then fix the wire in place with a wire stop.
