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 1M
Ω
or more exists between the terminal
block 1 to 3 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.
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.

When a test run is not
performed properly
• When a test run is not performed properly, refer to
the error code and the part to be checked on
“Troubleshooting”.
• When a test run is executed before installing the
external duct, a protection control may be activated
and lets the unit stop and the code P12 may be
displayed. (This is not due to a malfunction but to the
current control function of the DC motor in this unit.)
When a test run executed before installing the
external duct, select “Low” for the fan speed level or
cover the air outlet.
• In addition, stop the operation before replacing the
High-efficiency filter or opening the service panel.
After the test run, reset the circuit breaker of the
