(b) Installation of wired remote control (Optional
parts)
(i) Selection of installation location
Avoid the following locations
1) Direct sunlight.
2) Close to heating device.
3) Highly humid or water splashing area.
4) Uneven surface.
(ii) Installation procedure
1) Exposed fiting
a) Open the remote control case.
• Put a screw driver (flat-head) into the concavity
made on the upper part of a remote control unit
and twist it lightly to open the casing.
b) The cord of a remote control unit can only be
pulled out in the upward direction.
• Cut off with nippers or a knife a thin walled part
made on the upper end of the remote control unit's
bottom casing, and then remove burrs with a file
or the like.
c) Fix the remote controller unit's bottom casing onto
a wall with two wood screws supplied as accesso-
ries.
d) Connect the remote control to the terminal block.
Connect the terminals of the remote control to the
indoor unit with the same numbers. Because the
terminal block has polarity, the device becomes
inoperative if there are wrong connections.
Terminals: xRed wire, YWhite wire, ZBlack wire
• Use a cord of 0.3mm
(maximum) for a remote control unit cord. Re-
move a sheathe of the remote control unit cord for
the section laid within the remote control unit
casing.
The length of each wire that should be left after a
sheath is removed is as follows:
Black: 195mm, White: 205mm, Red: 215mm
e) Replace the top casing as before.
f) Use a cord clamp to attach the remote control cord
to the wall.
g) Set the functions according to the types of indoor
unit. See Section "Function Setting''.
