CLEANING BEFORE AND AFTER SEASONAL USE
WHAT TO DO WHEN STARTING UP AFTER A LONG
PERIOD OF NO USE
Confirm the following.
•
Check that the air inlet and outlet of indoor and outdoor
units are not blocked.
Remove any obstacle.
Obstacles decrease the fan speed, and cause performance
decrease and may damage the unit.
Clean the air filter.
•
After cleaning the air filter, make sure to reinstall it.
(Refer to “
2. MAINTENANCE
” on page 1.)
For information on how to install, remove, or clean the
optional air filter, refer to the installation manual attached to
the air filter.
•
Turn off the filter sign displayed on the remote controller
after turning on the power.
•
For details, refer to the operation manual attached to the
remote controller.
The indication can be turned off whether in operation or at
stop.
Turn on the power circuit breaker at least 6 hours before
operation.
•
This is required in order to activate the air conditioner
smoothly, and to protect the air conditioner.
•
The display on the remote controller will be shown when
the power circuit breaker is turned on.
HEATING OPERATION within 6 hours after power is sup
-
plied to the air conditioner.
Some model series perform the following operation to protect
the equipment.
If the HEATING OPERATION is performed within 6 hours after
power is supplied to the air conditioner, the indoor fan stops for
about 10 minutes during the outdoor unit operation to protect
the equipment.
The above operation is performed not only for installation, but
every time the power circuit breaker is turned off/on.
For comfortable use, do not turn off the power circuit breaker
during seasonal use of the HEATING OPERATION.
WHAT TO DO WHEN STOPPING THE AIR
CONDITIONER FOR A LONG PERIOD
Turn on FAN OPERATION for a half day on a nice day and
dry the indoor unit.
•
This can prevent the causes of mold.
Turn off the power circuit breaker.
•
When the power circuit breaker is on, some electricity is
used even if the air conditioner is not operating.
Turn off the power circuit breaker to save energy.
•
When the power circuit breaker is off, there is no longer a
display on the remote controller.
Clean the air filter.
•
Be sure to reinstall the air filter after cleaning.

dation and water leakage.
Ask your local dealer for details on cleaning the inside of the
indoor unit. This operation requires a qualified service person.
