procedure.
1) Using 500V-megger, check that resistance of 1M
Ω
or more exists between the terminal block 1 to 3 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 before operating.

For the procedure of the operation, refer to the attached
Owner’s Manual.

In order to prevent a serial operation, the forced test run is
released after 60 minutes have passed and returns to the
