• When the airflow is set to “ ”, indoor unit quiet operation will start and the noise
from the unit will become quieter.
• In indoor unit quiet operation, the airflow rate is set to a weak level.
• In DRY operation, the airflow rate setting is not variable.
• Always use a remote controller to adjust the angles of the louvers. If you attempt to move the louvers and fins forcibly with hand when they are
swinging, the mechanism may be broken.
• Be careful when adjusting the fins. Inside the air outlet, a fan is rotating at a high speed.
• At smaller airflow rates, the cooling (heating) effect is also smaller.
Note on airflow rate setting
• If the air conditioner is HEAT or DRY operation with the louvers kept stopped in the downward direction, the louvers will automatically start
operating in approximately an hour in order to prevent dew condensation.
