DUCT CONNECTORS
NOTE:
The electric heat accessory should be installed before
the supply air duct is attached to the supply air openings.
Refer to the electric heater kit instructions for proper installa-
tion.
Air supply and return may be handled in one of several ways
best suited to the installation. See Figure 5 for dimensions for
duct inlet and outlet connections.
The vast majority of problems encountered with combination
heating and cooling systems can be linked to improperly
designed or installed duct systems. It is therefore highly
important to the success of an installation that the duct sys-
tem be properly designed and installed.
Use flexible duct collars to minimize the transmission of vibra-
tion/noise into the conditioned space. If electric heat is used,
non-flammable material must be used.
Where return air duct is short, or where sound may be a prob-
lem, sound absorbing glass fiber should be used inside the
duct. Insulation of duct work is a must where it runs through
an unheated space during the heating season or through an
uncooled space during the cooling season. The use of a
vapor barrier is recommended to prevent absorption of mois-
ture from the surrounding air into the insulation.
The supply air duct should be properly sized by use of a tran-
sition to match unit opening. All ducts should be suspended
using flexible hangers and never fastened directly to the
structure. This unit is not designed for non-ducted (freeblow)
applications. Size outlet plenum or transition to discharge
opening sizes shown in Figure 5.
Duct work should be fabricated and installed in accordance
with local and/or national codes. This includes the standards
of the National Fire Protection Association for Installation of
Air-Conditioning and Ventilating Systems, NFPA No. 90B.

Use 1/2" screws to connect ductwork to bottom of
unit. Longer screws will pierce the drain pan and
cause leakage. If pilot holes are drilled, drill only
though field duct and unit bottom flange.
