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
1MΩ or more exists between the terminal
block of the power supply 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 be for
operating.
• 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.

WARNING
Execute a test run
Use the remote controller to check operations. For
the operation procedures, refer to the Owner's
Manual provided. You can do forced operations by
using the test mode function in the following
procedure, under conditions that the thermostat is
off.
This test mode function will automatically stop after
60 minutes, to prevent continuous forced operation,
and do normal operation (operation according to set
temperature).
* Thermostat off: When the temperature of the
room reaches the set temperature, the
compressor of the outdoor unit stops, and
operation switches from "Cool" or "Heat" to "Fan".
The indoor unit is operating, but the outdoor unit
repeatedly turns on/off in response to the room
temperature.
• This test mode function does forced operation
that ignores the set temperature, so be aware
of the room temperature and be sure to do a
stop / end operation when your work is finished.
• This test mode function puts a higher than
normal load on the equipment, so only use it for
inspections and to check operations.
