VENT CONTROL (Units Without
Power Vent or Power Door Kits
Installed)
The vent control allows fresh air to
be drawn into the conditioned area.
This fresh air can provide ventilation
when the blower is operating, but it
will increase the heating or cooling
load and operating costs.
To obtain access to the vent control,
remove the cabinet front (see
Disassembly Procedures) and locate
the vent control lever on the left side
of the chassis.
Rotate the vent control lever to either
open or close the damper.
Hydronic Heat Installations
To avoid the risk of freezing the
steam or water coil during
prolonged shutdown periods, the
vent door must be left closed when
the outdoor temperature might fall
below freezing or a power door kit
must be installed.
Air Discharge Grille
The discharge grille can be adjusted
to expel air at either a 15° or 40°
angle.

Disconnect all electric power,
including remote disconnects before
servicing. Follow proper lockout/
tagout procedures to ensure the
power can not be inadvertently
energized. Failure to disconnect
power before servicing could result
in death or serious injury.
