Simple Remote Control Installation Manual
Read together with indoor unit's installation manual.
● F asten 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.
● M ake sure the power source is turned off when electric wiring work.
Otherwise, electric shock, malfunction and improper running may occur.
● D o 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
● D o not leave the remote control without the upper case.
I n 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 ( 3.5×16) 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 M ake certain to remove the screw on the bottom
surface of the remote control.
⑵ Remove the upper case of the remote control.
I nsert 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 P repare 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.
Lower case
Wiring outlet
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 M ount 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.
