ADJUSTING THE AIRFLOW DIRECTION

ADJUSTING THE AIRFLOW DIRECTION

1. Horizontal

CAUTION

The horizontal airflow can be adjusted by moving the vertical vanes with your hands to the left or right.

When the humidity is high, the vertical vanes should be in the front position during the cooling or dehumidifying operation. If the vertical vanes are positioned all of the way to the right or left, condensation may begin to form around the air vent and drip down.

2.Vertical The vertical airflow can be adjusted by moving the flap with the remote controller. Do not move the flap with your hands. Confirm that the remote controller has been turned on. Use the FLAP button to set either the sweep function or one of the six airflow direction settings.

A. Sweep function

The flap starts moving up and down to deliver air over the sweep range.

C. Auto flap function

The flap is set to the recommended position.

B. Setting the airflow manually

Referring to the above illustration, use the FLAP button to set the airflow direction within the range used during the cooling or dehumidifying operation.

NOTE

CAUTION

The flap automatically closes when the unit is off.

Use the FLAP button on the remote controller to adjust the position of the flap. If you move the flap by hand, the flap position according to the remote controller and the actual flap position may no longer match. If this should happen, shut off the unit, wait for the flap to close, and then turn on the unit again; the flap position will now be normal again.

Do not have the flap pointed down during cooling operation. Condensation may begin to form around the air vent and drip down.
