Test run
Before test run
Before turning on the power supply, carry out the
following procedure.
1) By using 500V-megger, check that resistance of
1MΩ or more exists between the terminal block
1 to 3 and the earth (grounding).
If resistance of less than 1MΩ is detected, do not
run the unit.
2) Check the valve of the outdoor unit being opened
fully.
To protect the compressor at activation time, leave
power-ON for 12 hours or more before operating.
Execute a test run
Operate the unit with the wired remote controller as
usual.
For the procedure of the operation, refer to the
attached Owner's Manual.
A forced test run can be executed in the following
procedure even if the operation stops by
thermostat-OFF.
In order to prevent a serial operation, the forced test
run is released after 60 minutes have passed and
returns to the usual operation.
CAUTION
Do not use the forced test run for cases other than
the test run because it applies an excessive load
to the devices.
Wired remote controller
Be sure to stop the air conditioner before making
settings.
(Change the setup while the air conditioner is not
working.)
