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.
[Method of Mounting Conduit]
•
When connecting indoor units for 3 rooms or more, open knockout holes without deforming the conduit mounting plate.
1) Dismount the service lid by removing the 2 screws.
2) Slide the protection plate up and remove it.
3) Pass wires through the conduit and secure them with a lock nut.
