Installation Of Remote Controller (Option Parts); Recessed Fitting; Precation In Extending The Remote Controller Cord - Mitsubishi Heavy Industries FDC112KXEN6 Technical Manual

(2) Installation of remote controller
(Option parts)
(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 case.
• Put a screw driver (flat-head) into the concavity
made on the upper part of a remote controller and
twist it lightly to open the casing.
2) 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 controller
bottom casing, and then remove burrs with a file
or the like.
3) Fix the remote controller bottom casing onto a wall
with two wood screws supplied as accessories.
4) Connect the remote controller cord to the termi-
nal block. Connect between the remote controller
terminals (x, Y) and the indoor unit terminals
(x, Y). (x and Y have no polarity.)
Wiring path will be as shown below depending on
the direction to take out.

For all types : 0.3mm
Note 1) Use cables up to 0.5mm
inside the remote controller casing and connect to a
different size cable at a vicinity point outside the remote
