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 ter-
minal block.) Doing so may cause electric shock or fire.
• Be sure to install an earth leakage breaker. (One that can handle higher harmonics.)
(This unit uses an inverter, which means that an earth leakage breaker capable of handling harmonics must be used, in order
to prevent malfunctioning of the earth leakage breaker 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.
<Wiring procedure>
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.
3) Be sure to match the symbols for wiring and
piping.
4) Pull the wire lightly to make sure that it does not
disconnect.
5) Pass the wiring through the cutout on the bottom of
the protection plate and attach the protection plate.
6) After completing the work, reattach the service lid to its original position.
