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 a ground fault circuit interrupter breaker. (One that can handle higher harmonics.)
(This unit uses an inverter, which means that it must be used a ground fault circuit interrupter breaker capable handling
harmonics in order to prevent malfunctioning of the ground fault circuit interrupter breaker itself.)
• Use an all-pole disconnection type breaker with at least 1/8 inch (3mm) between the contact point gaps.
• When carrying out wiring connection, 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 safety breaker until all work is completed.
1) Strip the insulation from the wire (3/4inch (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
screwdriver be used to tighten the screws.
