Ventilation Control
NOTE: One shipping screw must be removed from the vent door
before use. See the Installation Instructions in the back of this
manual. If you do not plan to use the ventilation feature, leave the
one screw in place.
The ventilation control lever is located at the lower left side of the
Zoneline unit, behind the room cabinet. The position of the lever
can be adjusted with the wing nut.
When set at the closed position, only the air inside the room is
circulated and filtered.
When set at the open position, some outdoor air will be drawn
into the room. This will reduce the heating or cooling efficiency.
Energy Tip: Keep the vent control in the closed position. The room
air will be filtered and circulated.
Air Direction

4 louver screws that hold the louver insert in place. Rotate the
louver insert 180°, replace the screws and the room front
Remove the room front and rotate the louver
