Test run
■
Before test run
• Before turning on the power supply, carry out the
following procedure.
1) By using insulation tester (500VMΩ), check that
resistance of 1MΩ or more exists between the
terminal block L to N 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 remote controller as usual.
For the procedure of the operation, refer to the
attached Owner's Manual to the outdoor unit.
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, 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 discharge.
In addition, stop the operation before replacing the
High-effi ciency fi lter or opening the service panel.
