Test run

Before test run
• Before turning on the power supply, carry out the
following procedure.
1) Using 500V-megger, check that resistance of
1MΩ or more exists between the terminal block of
the power supply and the earth (grounding).
If resistance of less than 1M 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 be for operating.
• Never press the electromagnetic contactor to forcibly
perform a test run. (This is very dangerous because
the protective device does not work.)
• Before starting a test run, be sure to set addresses
following the installation manual supplied with the
outdoor unit.
Executing a test run
Using the remote controller, operate the unit as usual.
For the procedure of the operation, refer to the
attached Owner's Manual.
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.
