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.
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 shipping bolts located on the
mounting surfaces of the sections (see Figure 16).
3. Apply the gasketing to one of the mating surfaces; see Figure 16, Figure 17, and Figure 18.
