9 Test run
Before test run
y 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.
y To protect the compressor at activation time, leave
power-ON for 12 hours or more be for operating.
y Before starting a test run, be sure to set addresses
following the installation manual supplied with the
outdoor unit.
◆ Requirements for turning

Execute a test run
y 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.
