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.

Drain piping
1) Connect the drain hose, as described right.
2) Remove the air filters and pour some water into the drain pan to check the water
flows smoothly.
3) If drain hose extension or embedded drain piping is required, use appropriate
parts that match the hose front end.

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.
