Top Discharge
On units that are in the top discharge conguration, it is the
installer’s responsibility to ensure there can be no leakage at
or around the duct collar, or the applied ductwork. Leak proof
sealant is applied at the factory, however, additional sealant or
waterproof tape should be added at installation to ensure no
leakage occurs.
Figure 129 below shows the duct collar of a top discharge unit
and surrounding joints and seams to be inspected and sealed.

Side Discharge
On units that are in the side discharge conguration, the same
rules as top discharge for unit leakage apply. It is the installer’s
responsibility to ensure there can be no leakage at or around
the duct collar, or the applied ductwork.
Additional support must be given to ductwork to avoid the
deformation of the duct collar and damage to the unit.
Figure 130 below shows the duct collar and surrounding area
of a side discharge unit.

CAUTION
Please be careful when removing shipping cover and installing duct work.
Damage to top panels in this area could cause leaks that could cause
damage to unit and building. Inspect all seams and apply sealant and/or
waterproof tape to seams prior to operation.
