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.
Before starting a test run, set addresses by

Execute a test run
■
When a fan operation is to be performed for an
•
individual indoor unit, turn off the power, short
circuit CN72 on the circuit board, and then turn
the power back on. (Set the operation mode to
"fan" to operate the unit.) When the test run has
been performed using this method, be sure to
release the short circuit of CN72 after the test
run is completed.
Operate the unit with the remote controller as usual.
For the procedure of the operation, refer to the
Owner's Manual attached 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.
Do not use the forced test run for cases
•
other than the test run because it applies an
excessive load to the devices.
