1.5.2 Installation of wired remote controller

(a) 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.
(b) Installation procedure
a) Exposed fiting
1) Open the remote controller cover and unscrew
the screw located beneath the switch.
2) Open the remote controller case.
• Put a screw driver (flat-head) into the concav-
ity made on the upper part of a remote control-
ler and twist it lightly to open the casing.
3) The cord of a remote controller 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 rmote con-
troller bottom casing, and then remove burrs
with a file or the like.
4) Fix the remote controller bottom casing onto
a wall with two wood screws supplied as ac-
cessories.
5) Connect the remote controller to the termi-
nal block. Connect the terminals of the re-
mote controller 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
