1.19. Airflow control
The airflow control holds the two upper and lower louvers at special
positions during operation to prevent discharged air from directly blow-
ing onto people in the room.
1.19.1 Cooling/dehumidifying operation
1) When the airflow button is pressed
The upper louver is set at an upward angle to send the air along the
ceiling.
1.19.2 Heating
1) When the airflow button is pressed
The lower louver is positioned straight downward to send the air along
the wall.
The upper louver is set at a downward angle.
1.19.3 Adjustment of Coanda-effect angle from remote
control
The louver direction can be finely adjusted to create a Coanda airflow
when the upper and lower louvers are set to "
dehumidifying operation, or to "
If it is difficult to produce a Coanda airflow along the ceiling in cooling
operation because the air conditioner is not installed close to the ceil-
ing or there is a beam or lighting fixture on the ceiling, or if it is difficult
to produce a Coanda airflow along the wall in heating operation
because furniture is located below the air conditioner, perform fine
adjustment of the louver direction by following the procedure
described below and obtain a desirable airflow.
1) Adjustment of Coanda airflow direction in heating oper-
ation
1) Set the operation mode to Heating and the Airflow Up/Down to
" " using the remote control, and operate the air conditioner.
2) With the remote control pointed away from the main unit to disallow
signals from reaching the main unit, press the Stop button.
3) When the Airflow Up/Down button is held down for more than 5
seconds, the display shows "
4) Now, the air conditioner is ready for adjustment of the Coanda air-
flow direction. Each pressing of the Airflow Up/Down button
changes the display on the main unit in the order shown in the table
below, and the louver direction changes accordingly. Adjust the
direction while checking the actual louver angle and airflow direc-
tion.
5) After the adjustment is completed, press the Stop button on the
remote control.

1.20. Difference of operation in Auto and Manual modes
In the Auto mode, the temperature setting is automatically determined
based on the outside air temperature. In addition, the air conditioner
operation differs from the operation in the Manual mode as explained
below.
1.20.1 Difference relating to set temperature

1.21. Limitation on operating frequency in heating opera-
tion
If any of the following conditions is met 1 minute after operation star-
tup, the operating frequency is decreased to 90% in order to reduce
the operating sound and save energy in exchange for room warming
speed.
1) First operation after power ON
2) Outside air temperature is 3°C or higher
3) Room temperature is 10°C or higher, or difference between set
temperature and room temperature is 15°C or less
4) Current time is between 20:00 and 7:00
Note that the limitation is effective only for 60 minutes after operation
startup.
