How to install the remote controller
(Optional Controller)
CAUTION
●
Do not twist the control
wiring with the power
wiring or run it in the
same metal conduit,
because this may cause
malfunction.
●
Install the remote con-
troller away from sources
of electrical noise.
●
Install a noise filter or
take other appropriate
action if electrical noise
affects the power supply
circuit of the unit.
The mounting position for the remote controller
should be located in an accessible place for control.
Never cover the remote controller or recess it into the
wall.
(1) When you open the decorative cover, you will see 2
gaps under the remote controller. Insert a coin into
these gaps and pry off the back case. (Fig. 6-1)
6-1. When Using a Wall Box for Flush Mounting
●
If local codes allow, this remote controller can be
mounted using a conventional wall box for flush
mounting.
(2) Attach the back case with the 2 small screws pro-
vided. Using a screwdriver, push open the cut-outs
on the back case. These holes are for screws.
Use the spacers and take care not to tighten the
screws excessively. If the back case will not seat
well, cut the spacers to a suitable thickness.
(Fig. 6-1)
(3) Connect the remote controller wiring (2 wires) cor-
rectly to the corresponding terminals in the electri-
cal component box of the indoor unit.
(4) To finish, fit the back tabs of the case into the
remote controller and mount it.
CAUTION
When wiring, do not con-
nect the remote controller
wires to the adjacent termi-
nal block for the power
wiring. Otherwise, the unit
will break down.
CAUTION
Do not supply power to the
unit or try to operate it until
the tubing and wiring to the
outdoor unit is completed.
