• Install the remote controller at a height of 1 to 1.5 m from the floor so that the average temperature in the room
can be detected.
• Do not install the remote controller in a place exposed to direct sunlight or direct outside air, such as the side of
a window.
• Do not install the remote controller in a place behind something or to the rear side of an object, where air flow is
not sufficient.
• Do not install the remote controller in a freezing box or refrigerator, as the remote controller is not waterproof.
• Install the remote controller vertically to the wall.
◆Installation dimension

◆Remote control wiring and inter-unit wiring between remote controllers
Do not allow the wire for the remote controller (communication wire) and the wire for AC220-240 V to come into
contact or put them together in one electrical conduit; otherwise, the control system may have trouble due to noise.
◆Installation of multiple remote controllers
To install two or more adjacent remote controllers, follow the instructions in the Fig. 1 and 2.

1. Test mode
Set for the test operation after installation.
Before the test mode
• Perform the followings before turning on the power:
1) By using 500 V-megger, check that resistance of 1 MΩor more exists between the terminal block of the
power supply and the earth (earthing).
If resistance of less than 1 MΩis detected, do not run the unit.
2) Check all valve of the outdoor unit is opened fully.
• To protect the compressor at the time of startup, leave the power on for 12 hours or more before operation.
• Do not press the electromagnetic contactor to forcibly perform the test mode. (It is very dangerous because the
protective device does not work.)
Performing the test mode
For the procedure of the operation, refer to the supplied Owner’s Manual. A forced test mode can be performed
according to the following procedure when the room temperature rises / falls enough for the thermostat to turn off.
In order to prevent a continuous operation, the forced test operation is released after 60 minutes have passed and
returns to the normal operation.
CAUTION
Do not perform the forced test mode for purposes other than the test mode because it applies an excessive load to the
devices.
