Duct System Installation
- Proper duct sizing and
design is critical to the performance of the unit. The
duct system should be designed to allow adequate
and even airfl ow through the unit during operation.
Air fl ow through the unit MUST be at or above the
minimum stated airfl ow for the unit to avoid equipment
damage. Duct systems should be designed for quiet
operation. Refer to Figure 3 for horizontal duct system
details or Figure 8 for vertical duct system details. A
fl exible connector is recommended for both discharge
and return air duct connections on metal duct systems
to eliminate the transfer of vibration to the duct
system. To maximize sound attenuation of the unit
blower, the supply and return plenums should include
internal fi berglass duct liner or be constructed from
ductboard for the fi rst few feet. Application of the unit
to uninsulated ductwork in an unconditioned space is
not recommended, as the unit’s performance may be
adversely affected.
At least one 90° elbow should be included in the
supply duct to reduce air noise. If air noise or excessive
air fl ow is a problem, the blower speed can be
changed. For airfl ow charts, consult submittal data for
the series and model of the specifi c unit.
If the unit is connected to existing ductwork, a
previous check should have been made to ensure that
the ductwork has the capacity to handle the airfl ow
required for the unit. If ducting is too small, as in the
replacement of a heating only system, larger ductwork
should be installed. All existing ductwork should be
checked for leaks and repaired as necessary.
