TEST RUN
A wired remote controller is necessary for this function. This function cannot be operate with a wireless
remote controller.
Before test run
• Before turning on the power supply, carry out
the following procedure.
1) Using 500V-megger, check that resistance
of 1M
Ω
or more exists between the terminal
block of the power supply and the earth
(grounding).
If resistance of less than 1M
Ω
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.
WARNING
• Never press the electromagnetic contactor
to forcibly perform a test run. (This is very
dangerous because the protective device
does not work.)
• Before starting a test run, be sure to set
addresses following the installation manual
supplied with the outdoor unit.
How to execute a test run
Using the wired remote controller, operate the unit
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 thermo.-
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.
