Test run
Before test run
• Before turning on the circuit breaker, carry out the
following procedure.
1) By using insulation tester (500V Megger), check
that resistance of 1 M
Ω
or more exists between the
terminal block L to N and the earth (grounding).
If resistance of less than 1 M
Ω
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 for operating.
• Before starting a test run, be sure to set addresses
following the Installation Manual supplied with the
outdoor unit.
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.
CAUTION
CAUTION
• Do not use the forced test run for cases other than the
test run because it applies an excessive load to the
devices.
