TEST RUN
n
Before test run
• Before turning on the power supply, carry out
the following procedure.
1) Using 500V-megger, check that resistance
of 1M
Ω
or more exists between the termi-
nal 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 protec-
tive device does not work.)
• Before starting a test run, be sure to set
addresses following the installation manual
supplied with the outdoor unit.
n
How to execute 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 follow-
ing 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.
