Duct System Installation
Proper duct sizing and design is critical to te
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 fi gure 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 will 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 insure 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.
