Wiring

WARNING

• Do not use tapped wires, stranded wires, extension cords, or starburst connections, as they may cause overheating, electrical 

shock, or fire.

• 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.

• Be sure to install an earth leakage breaker. (One that can handle higher harmonics.)

(This unit uses an inverter, which means that it must be used an earth leakage breaker capable handling harmonics in order to 
prevent malfunctioning of the earth leakage breaker itself.)

• Use an all-pole disconnection type breaker with at least 3 mm between the contact point gaps.
• Do not connect the power wire to the indoor unit. Doing so may cause electric shock or fire.

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

1) Strip the insulation from the wire (20mm).
2) Connect the inter-unit wires between the indoor 

and outdoor units 

so that the terminal num-

bers 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.

Shape the wires so that 
there is no lifting of the 
service hatch or other 
structural parts.

Secure the branch wiring firmly using 

the 4 

included screws

, as shown in the figure.

Secure firmly, making sure no outside pressure is 
exerted on the terminals.

Use the specified wires and 
connect them securely.

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.
