FRESH AIR INTAKE
All units are built with fresh air inlet slots punched in
the service panel.
If the unit is equipped with a fresh air damper assembly,
the assembly is shipped already attached to the unit.
The damper blade is locked in the closed position. To
allow the damper to operate, the maximum and
minimum blade position stops must be installed. See
Figure 2.
Capacity and efficiency is based upon the fresh air
blank-off plate in place and is recommended for
maximum energy efficiency.
The blank-off plate is available upon request from the
factory and is installed in place of the fresh air damper
shipped with each unit.

CONDENSATE DRAIN
This unit employs an automatic condensate disposal
system consisting of a base drain pan, drain valve and
fan blade with slinger ring. A plastic drain hose extends
from the evaporator drain pain at the top of the unit to
the base drain pan at the bottom. At temperatures above
40°, the drain valve located between the condenser coil
and fan shroud is closed allowing water to build up in
the base to a height of 5/8" to 3/4". The fan blade with
slinger then rotates in this water and throws the water
onto the condenser coil. This disposes of the water by
evaporating it on the hot condenser.
At temperatures below 40°, the drain valve opens
draining the base pan and preventing freeze ups that
could damage the coil or fan blade.
