Section 9. Connecting the Ductwork

9.1 Duct Connection Considerations
Important: Due to the unique design of this unit,
which allows the electrical wiring to be routed within
the insulation, do not screw, cut, or otherwise puncture
the unit cabinet in any location other than the ones
illustrated in this Installer Guide or in an approved
accessory's Installer Guide.
Important: Under no conditions should metal
strapping be attached to the unit to be used as support
mechanisms for carrying or suspension purposes.
Important: On units with sheet metal returns: Return
air plenum must be flanged. Sheet metal drill point
screws must be 1/2" in length or shorter.
• The supply and return air ducts must be connected
to the unit with non flammable duct connectors.
• See the Outline drawing for sizes of the duct
connections.
• After the ducts are secured, seal around the supply
and return ducts to prevent air leakage.
• Insulate all duct work that will be outside of
conditioned spaces.
• Convertible Duct Flange Kits are available to connect
the supply plenum or for mounting on the discharge
opening to provide a "flush fit" for 1-1/2" duct board
applications.
• If front or rear return is required, the air handler must
be elevated - placed on a pedestal or plenum and
duct must be connected to this pedestal or plenum.
• If side return is required, the Side Return Kit #
BAYSRKIT100A accessory must be used. A remote
filter will be required.
• To ensure maximum efficiency and system
performance, the existing supply and return duct
system static pressures must not exceed the total
available static pressure of the air handler. Reference
ACCA Manual D, Manual S and Manual RS along
with the air handler Product Data and Service Facts
for additional information.
Note: Side return is not approved without Side Return
Kit # BAYSRKIT100. More than one Side Return Kit
may be necessary depending on the application.
Refer to the Installation Guide in BAYSRKIT100
for approved duct connections, sizing, number,
transitions, and accessory application.
Note: Duct work must be supported as appropriate.
See National and local codes for guidelines. Do not
depend on the unit to support duct work.
