NOTICE
Equipment Damage!
Failure to comply with temperature requirements could
result in equipment damage. The internal sections of
this unit containing electrical components must not
o
exceed 104 F operating temperature. Internal sections
of the unit which do not contain electrical components
o
must not exceed 200 F temperature.
WARNING
Risk of Unit Dropping!
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. Always place, assemble, and
suspend modules/subassemblies one at a time.
NOTICE
Microbial Growth!
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. The floor or
foundation must be level and the condensate drain at
the proper height for proper coil drainage and
condensate flow.
If a unit arrives in sections, then each section must be
individually hoisted, set on the housekeeping pad, roof
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. 38 for specific instructions.
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 Figure 22
Figure 22. Piers located in each corner and spaced evenly
every four feet

Note: Piers beneath shipping splits must be structurally
sound to support the weight of the unit.

Note: Piers beneath shipping splits must be structurally
sound to support the weight of the unit.
For proper operation, the unit must be installed level (zero
tolerance) in both horizontal axes. For vertical discharge
units, allow space under the unit for supply air ductwork
connections.
Note: Air handlers often include optional factory-
provided casing penetration entry points for field-
provided wiring. Consider overall unit
serviceability and accessibility before mounting,
running wires (power), making cabinet
penetrations, or mounting any components to the
cabinet.
