Test Run

Before test run
• Before turning on the circuit breaker, carry out the
following procedure.
1) By using 500 V-megger, check that resistance of
1 MΩ or more exists between the terminal block L
to N and the earth (grounding).
If resistance of less than 1 MΩ 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.
• Before starting a test run, be sure to set addresses
following the Installation Manual supplied with the
outdoor unit.
Execute a test run
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 thermo.-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.
