Test run
Before test run
• Before turning on the power supply, carry out the
following procedure.
1. Using 500 V-megger, check that resistance of 1
M
Ω
or more exists between the terminal block of
the power supply and the earth (earthing).
If resistance of less than 1 M
Ω
is detected, do not
run the unit.
2. Check all 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.
• Do not 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, set addresses following
the Installation Manual supplied with the outdoor
unit.
How to execute a test run
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
continuous 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.
Wired remote controller (NRC-01HE)
