Special cautions on wiring.
Use shielded wires for inter-unit control wiring
(c) and ground the shielded on both sides.
All wiring except inter-unit control wiring (c) has
polarity.
Otherwise misoperation due to noise may be
generated at times.
When connecting each power wire to the corresponding terminal, follow instructions “How to connect wiring to the terminal” and
fasten the wire securely tight with the fixing screw of the terminal plate.

HOW TO INSTALL THE REMOTE CONTROLLER
(OPTIONAL CONTROLLER)
Remote controller wiring can be extended to max. 500m.
6. HOW TO INSTALL THE REMOTE CONTROLLER (OPTIONAL PART)
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 controller 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 over the
remote controller or recess it into the wall.
(1)
When you open the decorative cover, you will see two
gaps under the remote controller. Insert a coin into
these gaps and pry off the back case.
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 provided.
Using a screwdriver, push open the cutouts 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.
(3)
Connect the remote controller wiring (3 wires) correctly
to the corresponding terminals in the indoor unit’s
electrical component box.
CAUTION
• When wiring, do not connect the remote controller
wires to the adjacent terminal 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.
(4)
To finish, fit the back case’s tabs into the remote
controller and mount it.
