Installation

DUCT CONNECTIONS

Supply Duct

The supply ductwork must be attached to the outside
of the flange on the air discharge end of unit. Flexible
connectors may be used if desired.

Return Duct

The return ductwork should be attached to the air
return side (bottom or side) of unit using sheet metal
screws or other fasteners.

For side return air inlet installation see the Figures 3
and 4.

FILTER INSTALLATION

Internal filter rack and a 1 inch disposable filter are
standard on all models. Refer to the Specifications
section for dimensions.

AIR SYSTEM

Existing Ductwork

It is the responsibility of the installer to inspect all
previously installed air distribution systems to
determine its suitability for the new heating and/or
cooling system. Existing ductwork may have to be
modified and/or insulated to provide satisfactory air
distribution.

Ductwork Installation

Connect the supply-air duct over the outside of 3/4-in.
flange on the unit’s discharge side. Secure the duct to
the flange with proper fasteners for the type of duct
used. Support the duct independently.

Use flexible connectors (if desired between the
ductwork and the unit to prevent transmission of
vibration.

Use insulation with vapor barrier for ductwork passing

Attachment Methods Using Straps

Method 1

Use (4) #8 x 3/4 sheet metal screws for each strap.
Straps to be vertical against the unit’s sides and not
allowed to be pulled away from the sides.

Method 2

Fold all straps under the furnace and secure with (4)
#8 x 3/4 sheet metal screws (2 screws at the side and
2 screws at the bottom. (Care must be taken not to
drive the screw through the coil.)
