•
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.

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
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.
