TEST RUN
Before test run
• Before turning on the power supply, carry out the
following procedure.
1) Using 500V-Megger, check that the resistance
of 1MΩ or more exists between the terminal
block of the power supply and the earth

If resistance of less than 1MΩ 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.
