CAH-SVX01A-EN 11
• Personnel should be positioned
overhead and on the ground to
guide the crane or helicopter
operator in positioning the
sections.
• The air handler is not designed
to be lifted, rigged or ceiling
suspended from the top of the
unit.
• Never stack the pipe cabinet and
inlet hoods on the unit as the
unit is being lifted.
• Do not attach the intake/exhaust
hoods to the unit prior to lifting
the unit. Doing so may damage
the equipment. Attach the hoods
to the unit only after all sections
are in place.
Unit Assembly
Note: If the unit is shipped as a
complete assembly, go to “Coil
Piping and Connections” on
page 28.
Prior to unit assembly, refer to the
unit submittal drawings and unit
tagging for correct placement of
sections. Failure to review the
submittal drawings could result in
performance or assembly problems.
If there are any discrepancies,
contact your local Trane sales
representative before proceeding.
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.
Units may be mounted on the roof
with a roof curb or pier mount. Units
may be mounted indoors on
housekeeping pads. Refer to
submittals for unit dimensions and
openings.
Note: For proper operation, the unit
must be supported around the entire
unit base perimeter. If the unit is
shipped in sections, the entire
section perimeter must be
supported, as well as at the base
channels of the unit splits.
Provide clearance around the unit to
allow adequate free air and
necessary service access. Also,
allow room for supply and return
piping, ductwork, electrical
connections, and coil removal.
The building roof must be able to
support the entire weight of the unit,
roof curb and accessories. See
submittals for approximate unit
weights.
• Preparation of the roof curb or
pier mount and roof openings
should be completed prior to
lifting the unit to the roof.
• Check that the gasketing or
sealant on the roof curb is intact
and provides an airtight seal with
the unit base.
• Complete all ductwork, piping
and electrical connections only
after mounting the unit.
Assembly Hardware
Air handlers ship with all necessary
assembly hardware and gasket
material. This hardware is packaged
in either a clear plastic envelope or
cardboard box and can be found
inside one of the sections. If space
inside a section is not adequate, a
crate or pallet will be loaded onto
the bed of the truck. Check the Parts
List on the Field Assembly drawing
against the contents of the crate. Do
not proceed with unit assembly until
verification that all materials are
present. The number of sections to
be assembled often makes it
necessary to use more than one
section to ship the material. Please
check all sections thoroughly before
contacting your local Trane sales
engineer to report missing
hardware.
