Methods of test run
◆
A test run is executed by using a
remote control
Operate the system normally to check the running
condition using the wired remote control. Follow the
instructions in the supplied owner’s manual when
operating the unit.
If a wireless remote control is used 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.
