Installation Instructions

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 the

two screws in place.

The ventilation control lever is located at the lower left side of the

Zoneline unit, behind the room cover. 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 in an 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 to prevent

unconditioned air from entering the room.

* Not on Make Up Air Module

Air Direction

To change the air direction, remove the room cover. Remove the

4 louver screws that hold the louver insert in place. Rotate the

louver 180°, reinstall and replace the screws and the room cover.
