Test run

Before test run

Confirm that the valve of the refrigerate pipe of the
outdoor unit is OPEN.
• Before turning on the power, confirm that the
resistance between the terminal block of power
supply and the earth is more than 2MΩ using a 500V
megohmmeter.
Do not run the unit if it is less than 2MΩ.
CAUTION
• Turn on the power and turn on the case heater of
the compressor.
To save the compressor when it is activated, leave
the power on for more than 12 hours.
Methods of test run
When executing a test run using
a remote controller
Operate the system normally to check the running
condition using the wired remote controller. Follow
the instructions in the supplied owner's manual when
operating the unit.
If you use a wireless remote controller for operations,
follow the instructions in the installation manual
supplied with the indoor unit.
To execute a test run forcibly under the condition that
the thermostat automatically turns the unit off due to
the indoor temperature, follow the procedure below.
The forcible test run will automatically stop after
60 minutes to prevent continuous forcible running and
return to normal running.
CAUTION
Do not use forcible running except for a test run as it
overloads the unit.
