Indoor Unit Installation
4.
Wiring
1) Strip wire ends (15mm).
2) Match wire colours with terminal numbers on indoor and outdoor unit’s terminal blocks and firmly screw wires to the
corresponding terminals.
3) Connect the earth wires to the corresponding terminals.
4) Pull wires to make sure that they are securely latched up, then retain wires with wire retainer.
5) Shape the wires so that the service lid fits securely, then close service lid.
WARNING
• Do not use tapped wires, stranded wires, extension cords, or starburst connections, as they may cause overheating, electri-
cal 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.
• Do not connect the power wire to the indoor unit. Doing so may cause electric shock or fire.
• Use an all-pole disconnection type breaker with at least 3mm between the contact point gaps.

4)When extending the drain hose, use a commercially
available extension hose with an inner diameter of
16mm. Be sure to thermally insulate the indoor section
of the extension hose.
5)When connecting a rigid polyvinyl chloride pipe
(nominal diameter 13mm) directly to the drain hose
attached to the indoor unit as with embedded piping
work, use any commercially available drain socket
(nominal diameter 13mm) as a joint.
