Fresh Air Vent
Fresh Air Vent
The vent control allows outside air to be drawn into the
conditioned area. This outside air can provide ventila-
tion when the blower is operating, but it will increase the
heating or cooling load and operating costs.
* IMPORTANT NOTES FOR PEFORMANCE TESTING!
1. The Activation Plate must be installed during Perfor-
mance Testing in order to obtain accurate test results.
2. DIP Switch 8 on the Main Board must be set to ON
(Constant Fan) position during testing (refer to Control
Board paragraph on page 41).
3. The DR. PTAC Activation Switch must be in the OFF
position when Activation Plate is installed.
To obtain access to the vent control:
1. Remove the cabinet front (see Front Removal).
2. Remove the shipping screw (if installed) from the
vent door.
3. Remove the label (if present) from over the vent con-
trol lever on the left side of the chassis. Remove the
vent door shipping screw.

thermostat. Not recommended for models with built-in
thermostats.

to be shared by an adjacent room. The kit mounts to the
top of the unit and can be configured for either right or
left discharge. The amount of air diverted to the second
room is adjustable.
The kit consists of a main duct for the room of origin
and an extension duct to reach the adjoining room and
terminal duct.
