from the unit will become quieter.
• In indoor unit quiet operation, the airflow rate is set to a weak level.

change the airflow rate setting.
• In DRY mode, the airflow rate setting is not variable.
• Always use a remote controller to adjust the angles of the flap. If you attempt to move the flap and louvers forcibly with hand when they are
swinging, the mechanism may be broken.
• Be careful when adjusting the louvers.
Inside the air outlet, a fan is rotating at a high speed.
• If the air conditioner is operated in COOL or DRY operation with the flap kept stopped in the downward direction, the flap will automatically
start operating in approximately an hour in order to prevent dew condensation.
Note on airflow rate setting
• At smaller airflow rates, the cooling (heating) effect is also smaller.
Notes on the angles of the flap
• The flap swinging range depends on the operation. (See the figure.)
