Adjusting airflow direction
For best cooling, adjust the louvers (adjustment plates
of up/down wind direction) appropriately. Cold air
descends, so to, and to cool a room tilt them
horizontally.
•
When the air conditioner is not working, the louvers
are directed horizontally automatically.
Wireless remote controller
To set the airflow direction
1
FIX button
•
The louver angle does not change immediately
after the FIX button is pushed. Check the louver
status, and push FIX button after a while.
•
In subsequent operations, the vertical airflow is
automatically set in the direction to which you
adjusted the louver using the FIX button.
To automatically swing the airflow
direction
Perform this function when the air conditioner is in
operation.

SWING button
Press the SWING button on the remote controller.
•
To stop the function, press the SWING button.
CAUTION
•
The FIX and SWING buttons will be disabled when the
air conditioner is not in operation (including when the
ON timer is set).
•
The louver angle does not change if the FIX button is
pushed during SWING operation. Stop the SWING
operation before changing the louver angle.
•
Do not operate the air conditioner for long hours with
the airflow direction set downward during the cooling
or dry operation.
Otherwise, condensation may occur on the surface of
the vertical airflow louver and cause dew dripping.
•
Do not move the vertical airflow louver manually.
Always use the FIX button.
If you move the louver manually, it may malfunction
during operation.
If the louver malfunctions, stop the air conditioner
once, and restart.
•
When the air conditioner is started immediately after it
was stopped, the vertical airflow louver might not
move for 10 seconds or so.
•
Louver operation is limited when performing group
control.
For cooling (COOL)
Direct the louvers horizontally.

NOTE
•
When other electric appliances are used at the same time, to avoid triggering the circuit breaker, power saving mode is
recommended. Of course power saving mode can be used to save energy as well.
•
Power saving mode consumes less energy, but may not cool the room as much as normal mode. (The maximum current is
limited to approximately 75 % (factory default) of the normal mode.)
•
Even when operation start / stop, operation mode change, or power reset is performed during the power saving mode, the
power saving mode is retained until the next operation.
