FILTERS

A 1-inch throwaway filter is supplied with each unit.

The filter slides into position making it easy to service.

This filter can be serviced from the outside by removing

the service door. A 1-inch washable filter and 2-inch

pleated filter are also available as optional accessories.

The internal filter brackets are adjustable to

accommodate the 2-inch filter by loosening two (2)

screws on each bracket assembly and sliding the

brackets apart to the required width and retightening the

four (4) screws.

FRESH AIR INTAKE

All units are built with fresh air inlet slots punched in

the service door.

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.

CONDENSATE DRAIN

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.
