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 MΩ or more exists between the terminal
block 1 to 3 and the earth (grounding).
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
Using the wired remote controller, operate the unit 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
Do not use the forced test run for cases other than the
test run because it applies an excessive load to the
devices.

▼ Periodic maintenance
• For environmental conservation, it is strongly recommended that the indoor and outdoor units of the air
conditioner in use be cleaned and maintained regularly to ensure efficient operation of the air conditioner.
When the air conditioner is operated for a long time, periodic maintenance (once a year) is recommended.
Furthermore, regularly check the outdoor unit for rust and scratches, and remove them or apply rustproof
treatment, if necessary.
As a general rule, when an indoor unit is operated for 8 hours or more daily, clean the indoor unit and outdoor
unit at least once every 3 months. Ask a professional for this cleaning / maintenance work.
Such maintenance can extend the life of the product though it involves the owner's expense.
Failure to clean the indoor and outdoor units regularly will result in poor performance, freezing, water leakage,
and even compressor failure.
• When a drain pump kit (sold separately) is installed.
If it is used in a place full of dust or oil mist, the pump will be clogged and proper drainage is disabled.
Clean the drain pump periodically. For how to clean the drain pump, contact the dealer.
