If using the factory-provided integral base frame for ceiling
suspension, individual sections and/or subassemblies will
have base frame shipping splits and base frame lifting
lugs. When using the base frame for ceiling suspension:
• Suspend the unit (on both sides of the unit) at each
shipping split lug as well as the four corners of the unit
(see
Figure 14 ). See submittal documentation for unit
lifting lug size.
• Bolt shipping splits together.
The hanger rods must extend through the bottom of the
base lug. It is the building engineer’s responsibility to
provide the appropriate hangers.
Shipping Gussets
Prior to pulling the shipping splits together, the shipping
gussets (see
Figure 15 ) should be removed to simplify
panel removal (except for hurricane units or units that
require OSHPD certification). If there is enough access
after joining the shipping splits, the gussets can be
removed after they are joined. The exception to this rule is
for stacked units where the first level is greater than 65
inches external height. For these units, 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.
Figure 15. Shipping gusset
Do not mistake the coil structural gusset (see Figure 16 )
used on larger units with the shipping gussets.

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 cardboard box 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.
