Test run

■ Before test run
Confirm that the valve of the refrigerate pipe of the
outdoor unit is OPEN.
• Before turning on the power, confi rm that the
resistance between the terminal block of power
supply and the earth is more than 1MΩ using a
500V megohmmeter.
Do not run the unit if it is less than 1MΩ.
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.
