Unit Placement
WARNING
Heavy Objects!
Always place, assemble, and suspend sections/subassemblies one at a time. Placing, assembling,
and/or suspending more than one section/subassembly at a time could result in death, serious
injury, or equipment damage.
NOTICE
Microbial Growth!
The roof curb 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 may cause
odors and damage to the equipment and building materials.
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 “Pipe
Cabinet Installation” on page 40 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 11 and Figure 12 .
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.
