Test run
Before test run
• Before turning on the power supply, carry out the
following procedure.
1) By using 500 V-megger, check that resistance
of 1 MΩ or more exists between the terminal
block 1 to 3 and the earth (grounding work).
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 before operating.
Execute a test run
Operate the unit with the wired remote controller 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 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.
