Wiring
WARNING
• Do not use tapped wires, extension cords, or starburst connections, as they may cause overheating, electric 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 a ground fault circuit interrupter. (One that can handle higher harmonics.)
(This unit uses an inverter. Therefore, a ground fault circuit interrupter capable of handling higher harmonics must be used in
order to prevent the ground fault circuit interrupter malfunctioning.)
•
Use an all-pole disconnection type circuit breaker with at least 1/8 inch (3mm) between the contact point gaps.
•
When carrying out wiring, take care not to pull at the conduit.
• Do not connect the power wire to the indoor unit. Doing so may cause electric shock or fire.
•
Do not turn on the circuit breaker until all work is completed.
1) Strip the insulation from the wire (3/4 inch (20mm)).
2) Connect the inter-unit wires between the indoor and outdoor units so that the terminal numbers match. Tighten the
terminal screws securely. It is recommended that a flathead screwdriver be used to tighten the screws.
The screws are packed with the terminal block.

[Method of mounting conduit]
• A protection plate is fixed for protection from the high-voltage section.
1) Dismount the stop valve cover by removing the screw.
2) Dismount the protection plate by removing the 2 screws.
3) Dismount the conduit mounting cover by removing the 2 screws.
4) Pass wires through the conduit and secure them with a lock nut.
5) After completing the work, reattach the stop valve cover, the conduit mounting cover, and the protection plate to its
original position.
