Step 4 — Provide Unit Support
ROOF CURB MOUNT
Accessory roof curb details and dimensions are shown in
Fig. 19-21. Assemble and install accessory roof curb in accor-
dance with instructions shipped with the curb.
NOTE: The gasketing of the unit to the roof curb is critical for a
watertight seal. Install gasket supplied with the roof curb as shown
in Fig. 19-21. Improperly applied gasket can also result in air leaks
and poor unit performance.
Curb should be level. This is necessary for unit drain to function
properly. Unit leveling tolerances are shown in Fig. 17. Refer to
Accessory Roof Curb Installation Instructions for additional infor-
mation as required.
Fig. 17 — Unit Leveling Tolerances
Install insulation, cant strips, roofing felt, and counter flashing as
shown. Ductwork must be attached to curb and not to the unit.
Thru-the-base power connection must be installed before the unit
is set on the roof curb.
If electric and control wiring is to be routed through the basepan,
remove knockouts in basepan located in control box area of access
panel, see Fig. 18. See Fig. 2-16 for basepan knockout locations
for location. Attach the service connections to the basepan.

Compressor Locations
SLAB MOUNT (HORIZONTAL UNITS ONLY)
Provide a level concrete slab that extends a minimum of 6 in.
(150 mm) beyond unit cabinet. Install a gravel apron in front of
condenser coil air inlet to prevent grass and foliage from obstruct-
ing airflow.
NOTE: Horizontal units may be installed on a roof curb if
required.
ALTERNATE UNIT SUPPORT
(IN LIEU OF CURB MOUNT)
A non-combustible sleeper rail can be used in the unit curb sup-
port area. If sleeper rails cannot be used, support the long sides of
the unit with a minimum of 4 equally spaced 4 in. x 4 in. (102 mm
x 102 mm) pads on each side. Locate pads so that they support the
rails. Make sure to avoid the fork openings.
