CAUTION
Regarding the Airflow of the Indoor Unit
The air that is pulled in by the fan (the “return air”) enters the
grille and is passed through the filter. It is then
cooled/dehumidified/heated through the heat exchanger.
The direction of the air output is manipulated up and down by the
motorized louver, and left to right via manually controlled vertical
deflectors. Some models may come with “dual-swing” capability,
which offers both a horizontal and vertical motorized air flow swing.
Controlling the System’s Airflow
1. Pressing the SWING buttons activates the louver.
• Press the Swing button to trigger the horizontal
flaps to swing up and down. Press this button again
to stop swing movement at the current angle.
• Press the Swing button to trigger the vertical
flaps to swing left and right. Press this button again
to stop swing movement at the current angle.
2. If the vertical deflectors (which are located
underneath the flaps) are adjusted manually,
they can be used to fix the airflow in a certain
vertical position before turning the system on.
