CAUTION
• Attach the cable clamp firmly by holding the connection cable, and make sure that the
clamp is fixed securely.
Incomplete attachment of the cable clamp might cause a malfunction of the open
panel.
• Match the terminal block numbers and connection cable colors with those of the
outdoor unit or branch box.
Erroneous wiring may cause burning of the electric parts.
• Connect the connection cables firmly to the terminal block. Imperfect installation may
cause a fire.
• Always fasten the outside covering of the connection cable with the cable clamp.
(If the insulator is chafed, electric discharge may occur.)
• Always connect the ground (earth) wire.
• Do not use the ground (earth) screw of the indoor unit for the connection other than a
specified outdoor unit.

3.5. Remote controller installation
• Check that the indoor unit correctly receives the signal from the remote controller, then
install the remote controller holder.
CAUTION
Do not install the remote controller holder in the following conditions:
• Any places exposed in direct sunlight
• Positions affected by the heat from a stove or heater
3.5.1. Remote controller holder installation
•
Install the remote controller a maximum distance of 22 ft (7 m) m from the remote con-

3.5.2. Remote controller custom setting
■
Custom code setting
By setting custom code of indoor unit and remote controller, you can specify the air condi-
tioner which the remote controller controls.
When two or more air conditioners are in the room and you wish to operate them sepa-
rately, set the custom code (4 selections possible).
NOTE:
If custom codes is different between the indoor unit and the remote controller,
the indoor unit cannot receive a signal from the remote controller.
How to set the remote controller custom code
(1) Press
until the indicators on the remote controller turn off.
(2) Press down [MODE] for more than 5 seconds.
The current custom code will be displayed (initially set to ).
(3) Press [TEMP./SELECT (
)] to change the custom code between
A (
) ↔ B ( ) ↔ C (
/
) ↔ D (
).
* Match the custom code on the display to the air
conditioner custom code.
(4) Press [MODE] again.
The custom code will be set.
The display will return to the original display.
• To change the air conditioner custom code, contact an authorized service
personnel (initially set to ).
• If you do not press any buttons for 30 seconds after the custom code is displayed,
the display returns to the original display. In this case, repeat the setting from step 2.
• Depending on the remote controller, the custom code may return to when
replacing the batteries. In this case, reset the custom code as necessary. If you
do not know the air conditioner custom code, try each code until you find the code
which operates the air conditioner.
4. OPTIONAL INSTALLATION WORK
