CONDENSATE DRAIN – EVAPORATOR

A plastic drain hose extends from the drain pan at the
top of the unit down to the unit base.  There are
openings in the unit base for the drain hose to pass
through.  In the event the drain hose is connected to a
drain system of some type, it must be an open or vented
type system to assure proper drainage.

CONDENSATE DRAIN – CONDENSER

A hole is provided in the unit base to accept a Drain
Connection Kit 8620-160.  This allows connection of
the unit base pan to a drain if so desired.  (See Figure 3
and instructions provided with the 8620-160 kit.)  In the
event the drain hose is connected to a drain system of
some type, it must be an open or vented type system to
assure proper drainage.

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.

All capacity, efficiency and cost of operation
information as required for Department of Energy
“Energyguide” Fact Sheets 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.
