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.
CAUTION
When connecting the connection wires to the
terminal board using a single core wire, be sure
to perform curling.
Problems with the work may cause heat and fires.
