Test run
Before test run
• Before turning on the power supply, carry out the
following procedure.
1) By using 500 V-megger, check that resistance
of 1 MΩ or more exists between the terminal
block 1 to 3 and the earth (grounding).
If resistance of less than 1 MΩ 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.

NOTE
• Be sure to operate the unit, following the instruction
manual
• Do not run the air conditioner in forced cooling mode
for a long time since it overloads the air conditioner.
• Forced heating is not available for trial runs. To
perform a test run, set the unit to heating mode with
the remote controller. The unit might not operate in
heating mode, however, depending on temperature
conditions.
1
Hold down the TEST button for over 10
seconds. With a beep sound, the unit is set
to the forced cooling mode.
In approximately three minutes, it is forced to start
in cooling mode. Determine that cool air comes out
of the unit. If the unit won't start, check the wiring.
2
Push the TEST button again (for about one
second) to stop a trial run.
The upper and lower wind direction changing
blades close, and the unit stops operation.
Checking remote transmission
1. Push the ON/OFF button on the remote controller to
determine that it works properly.
• Pushing the TEST button once (for about one
second) causes the unit to enter auto operation
mode. Hold down the TEST button for over 10
seconds to begin forced cooling.
• Even if you select cooling with a remote controller,
the unit does not always perform cooling operation,
depending on temperature conditions. Check the
wiring and piping of the indoor and outdoor units in
forced cooling mode.
