Wiring
WARNING
1) Do not use tapped wires, stranded wires, extension cords, or starburst 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 3mm 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.
Observe the notes mentioned below when wiring to the power supply terminal board.
Precautions to be taken for power supply wiring.
Use a round crimp-style terminal for connection to the power supply terminal board.
In case it cannot be used due to unavoidable reasons, be sure to observe the follow-
ing instruction.
Place the round crimp-style terminals on the wires up to the covered part and
secure in place.
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.
3) Pull the wire and make sure that it does not disconnect. Then fix the wire in place with a wire stop.

Use the specified wire type
and connect it securely.
Firmly secure wire retainer so wire
terminations will not receive external stress.
Shape wires so
that the stop valve
