WARNING
• Donotusetappedwires,extensioncords,orstarburstconnections,astheymaycauseoverheating,electricshock,orre.
• 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re.
• 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re.
• 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atheadscrewdriverbeusedtotightenthescrews.
The screws are packed with the terminal block.

[Method of mounting conduit]
•Aprotectionplateisxed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.
