ADJUSTING THE AIR DEFLECTORS

Adjustment of the conditioned air in the upward and

1

downward directions. According to “Dehumidifying” or “Cooling” operation, the horizontal air deflector is automatically set to the proper angle suitable for each operation. The deflector can be swung up and down and also set to the desired angle using the “ (AUTO SWING)” button. (If the angle of the deflector is changed, it will not return to the auto-set position after operations start unless the operation mode is switched.)

● If the “ (AUTO SWING)” button is

pressed once, the horizontal air deflector swings up and down. If the button is pressed again, the deflector stops in its current position. Several seconds (about 12 seconds) may be required before the deflector starts to move.

● If the deflector is not used at fixed angle, set

the horizontal air deflectors within range of blue mark on the side plate for “Dehumidifying” and “Cooling” operations.

● Swinging the air deflector is effective to reduce

unevenness of the temperature in the room.

● In “Cooling” operation, do not set the horizontal

air deflector out of the range of blue mark on the side plate and do not keep the horizontal air deflector swinging for a long time. Some dew may form on the horizontal air deflector and the dew may fall from it.

● When the “ (AUTO SWING)” button is

pressed while the operation is stopped, the horizontal air deflector moves and stops at the position where the air outlet closes.

● When the auto swing operation is performed, if

the horizontal air deflector is moved manually, the swinging range may drift. However, it will return to the original operation range after a short time.
