Lateral Duct Kit
NOTE: Recommended for use on models with remote
thermostat. Not recommended for models with built-in
thermostat.
Fresh Air Vent and Lateral Duct Kit
Fresh Air Vent
The optional fresh air vent control allows outside
air to be drawn into the conditioned area at 72 CFM
during fan operation. This outside air can provide
ventilation when the blower is operating, but it will
increase the heating or cooling load and operating
costs. The vent operation is fully automatic and
closes when no fan is running.
Lateral Duct Kit
The Lateral Duct kit allows the air from one PTAC
unit 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 in the
following configurations:
50:50 split, room 1:room 2
60:40 split, room 1:room 2
70:30 split, room 1:room 2
The kit consists of a main duct for the room of
origin and an extension duct to reach the adjoining
room and a terminal discharge grille.
