following procedure.
1) By using 500 V-megger, check that resistance
of 1 MΩ or more exists between the terminal
block L to N and the ground.
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.
• Before starting a test run, set addresses by following
the Installation Manual supplied with the outdoor
unit.
 Execute a test run
Operate the unit with the wired remote control as usual.

attached to the outdoor unit Owner's Manual.
A forced test run can be executed in the following
procedure even if the operation stops by turning the
thermostat - OFF.
In order to prevent a serial operation, the forced test
run is released after 60 minutes have passed and
