Installation

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.
