Ventilation Control
NOTE: Two shipping screws 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 these two
screws in place.
The ventilation control lever is located at
the middle left side of the Zoneline unit,
behind the room cabinet.
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
To change the air direction, remove the room
cabinet. Remove the 7 louver screws that hold
the louver insert in place. Flip the louver insert 180°,
replace the screws and the room cabinet. Remove the room cabinet and flip the louver
insert to change the air direction.
