Simple Remote Control Installation Manual
Read together with indoor unit's installation manual.
● Fasten the wiring to the terminal securely and hold the cable securely so as not to apply
unexpected stress on the terminal.
Loose connection or hold will cause abnormal heat generation or fire.
● Make sure the power source is turned off when electric wiring work.
Otherwise, electric shock, malfunction and improper running may occur.
● Do not install the remote control at the following places in order to avoid malfunction.
(1) Places exposed to direct sunlight
(2) Places near heat devices
(3) High humidity places
● Do not leave the remote control without the upper case.
In case the upper cace needs to be detached, protect the remote control with a packaging box
or bag in order to keep it away from water and dust.
Accessories Remote control, wood screw (φ3.5×16) 2 pieces
Prepare on site Remote control cord (2 cores) (Refer to [2. Installation and wiring of remote control])
[In case of embedding cord] Electrical box, M4 screw (2 pieces)
[In case of exposing cord] Cord clamp (if needed)
1. Installation procedure
In case of embedding cord
⑴ Make certain to remove the screw on the bottom
surface of the remote control.
⑵ Remove the upper case of the remote control.
Insert a flat-blade screwdriver to a concave portion of the bottom
surface of the remote control and slightly twist it, and the case is
removed.
⑶ Pre-bury the electrical box and remote control cord.
⑷ Prepare two M4 screws (recommended length: 12 – 16mm), and install the lower case to the electrical box.
Do not use a screw whose screw head is larger than the height of the wall around the screw hole.

⑸ Connect the remote control cord to the terminal block.
Connect the terminals (X and Y) of the remote control and the terminals (X and Y) of the indoor
unit. (No polarity of X and Y)
⑹ Mount the upper case for restoring to its former state so as not to crimp the remote control cord,
and secure with the removed screw.
6. Function setting
Each function of the remote control and the indoor unit is automatically set to the initial setting, which is the standard use, on the occasion of connecting the remote control with the indoor unit. In the case of the standard
use, the setting change is unnecessary. However, if you whould like to change the initial setting " ○ ", change the setting for only the item of the function number. Record the setting contents and stored them.

In case of exposing cord
⑴ Make certain to remove a screw on the bottom surface of the
remote control.
⑵ Remove the upper case of the remote control.
Insert a flat-blade screwdriver to a concave portion of
the bottom surface of the remote control and slightly
twist it, and the case is removed.
⑶ The remote control cord can be extracted from the
upper center.
After the thin part in the upper side of the remote
control upper case is scraped with a nipper or knife,
remove burr with a file.
⑷ The lower case of the remote control is mounted to
a flat wall with two accessory wood screws.
⑸ Connect the remote control cord to the terminal block.
Connect the terminals (X and Y) of the remote control and
⑴
the terminals (X and Y) of the indoor unit. (No polarity of X and
Screw
Y)
The wiring route is as shown in the right.
The wiring in the remote control case should be 0.3 mm
maximum.
Further, peel off the sheath.
The peeling length of each wiring is as follows:
X wiring : 160mm
Y wiring : 150mm
⑹ Mount the upper case for restoring to its former state so as not to
crimp the remote control cord, and secure with the removed screw.
⑺ In the case of exposing installation, secure the remote control cord to the wall surface with a
cord clamp so as not to loosen the remote control cord.
2. Installation and wiring of remote control
⑴ Wiring of remote control should use 0.3mm
⑵ Maximum prolongation of remote control wiring is 600 m.
If the prolongation is over 100m, change to the size below.
But, the wiring in the remote control case should be 0.3mm
Change the wire size outside of the case according to wire connecting. Waterproof treatment is
necessary at the wire
connecting section. Be careful about contact failure.
100 - 200m･････････････････0.5mm
Under 300m･････････････････0.75mm
Under 400m･････････････････1.25mm
Under 600m･････････････････2.0mm
