(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
1) Exposed fiting
a) Open the remote control case.
• Put a screw driver (flat-head) into the con-
cavity 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 rmote
control unit’s bottom casing, and then re-
move burrs with a file or the like.
c) Fix the remote control unit’s bottom casing
onto a wall with two wood screws supplied
as accessories.
d) Connect the remote control to the terminal
block. Connect the terminals of the remote
control to the indoor unit with the same num-
bers. Because the terminal block has polar-
ity, the device becomes inoperative if there
are wrong connections.
