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 leak detector. (One that can handle higher harmonics.)
(This unit uses an inverter, which means that it must be used an earth leak detector capable handling harmonics in order to
prevent malfunctioning of the earth leak detector itself.)
• Use an all-pole disconnection type breaker with at least 3mm 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 wire 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.
Shape wires so
that the service
cover and stop
valve cover fit
securely.
Make sure that the earth wire between the pull relief and terminal is longer than the other wires.
