removed after they are joined. The exception to this rule is
for size 35-50 stacked units. For these sizes, the gussets
should be left in place for the lower level unit unless they
are installed in a shipping split that contains a coil. The
other exception is when access to install or change out
front-loaded filters is restricted or blocked.

Section-to-Section Assembly

Air handlers ship with all necessary assembly hardware
and gasket material. The hardware should be packaged in
either a clear plastic envelope or yellow bag inside the fan
section, access section, or mixing box.
The number of sections to be assembled often makes it
necessary to use more than one section to ship the
assembly material; therefore, check all sections
thoroughly before contacting your Trane sales
representative to report missing items.
Sections are joined with gasketing applied to one of the
mating surfaces and hardware to bolt the sections
together. The gasketing for section-to-section joints is a
closed cell foam with adhesive backing.
To assemble the unit:
1. Locate the mounting hardware and gasket material.
2. All shipping supports and crating on the face of the
sections must be removed and discarded to permit
proper fit-up and sealing of the surfaces. Remove any
30
shipping bolts located on the mounting surfaces of the
sections (see
