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 M

Ω

 or more exists between the terminal block of the 

power supply and the earth (earthing).
If resistance of less than 1 M

Ω

 is 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.)

• Peel off the protective sheet affixed when the remote controller was shipped before performing a test run.

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.
