Note: Do not use a forklift on outdoor air handlers or
indoor air handlers/subassemblies that do not
have end cleat (see
A forklift may be used to lift a single section or small
subassembly, provided the forks extend under both ends
of the base frame, or as indicated in
should not contact the bottom of the air handler. Units
should only be lifted from the proper end identified by the
lifting label on the unit. A lifting crane or other means
should be used for larger units where forks cannot extend
under both base rails.

Unit Placement and Assembly
If the air handler ships in subassemblies or in individual
sections, some assembly is required, including:
•
Ceiling-suspended indoor unit assembly; see
Suspension," p.
17.
•
Section-to-section assembly; see
Assembly," p.
18.
WARNING
Toxic Fumes!
Keep open flame away from unit exterior or interior. Do
not weld or use cutting torch on the exterior or interior
of the unit. The unit contains polyurethane insulation.
Flame could produce toxic gas which could result in
death or serious injury.
NOTICE
Equipment Damage!
The internal sections of this unit containing electrical
components must not exceed 104
temperature. Internal sections of the unit which do not
contain electrical components must not exceed 200
temperature. Failure to comply with temperature
requirements could result in equipment damage.

Risk of Unit Dropping!
Always place, assemble, and suspend modules/
subassemblies one at a time. Placing, assembling, and/
or suspending more than one module/subassembly at
a time could result in module/subassemblies dropping
and crushing technicians which could result in death,
serious injury, or equipment damage.
Microbial Growth!
The floor or foundation must be level and the
condensate drain at the proper height for proper coil
drainage and condensate flow. Standing water and wet
surfaces inside the equipment can become an
amplification site for microbial growth (mold), which
could cause odors and damage to the equipment and
building materials.
If a unit arrives in sections, then each section must be
2 x 4
individually hoisted, set on the housekeeping pad, roof
block
curb, or pier mount and then assembled.
Refer to the unit submittals and unit tagging for correct
placement of all sections. If there are any discrepancies
between the submittals and the unit tagging, contact your
local Trane representative before proceeding.
Following the order of the sections on the unit submittals
and tagging, individually place each unassembled section
or subassembly in the appropriate installation location.
Note: Prior to placing fan section in the appropriate
installation location, verify shipping tie-downs
have been removed.
For outdoor units, the pipe cabinet must also be mounted
as an individual section. Refer to
Installation," p. 22
When mounting the unit on a roof curb, make sure the
gasketing between the roof curb and unit base provides an
airtight seal.
When mounting the unit on a pier mount, locate one pier
at each corner as a minimum, directly underneath any
shipping split (ensure full support under each side) and
then every four feet at equally spaced intervals around the
perimeter of the unit. Both the unit and the pipe cabinet
should be supported by their base around the entire
perimeter. See
