FRAME-MOUNTED INSTALLATION
Frame-mounted applications generally follow the sequence for
a curb installation. Adapt as required to suit specific installa-
tion plan.
Step 3 — Inspect Unit
Inspect unit for transportation damage. File any claim with
transportation agency.
Confirm before installation of unit that voltage, amperage and
circuit protection requirements listed on unit data plate agree
with power supply provided.
On units with hinged panel option, check to be sure all latches
are snug and in closed position.
Locate the carton containing the outside air hood parts; see
Fig. 13 and 14. Do not remove carton until unit has been rigged
and located in final position.
Step 4 — Provide Unit Support
ROOF CURB MOUNT
Accessory roof curb details and dimensions are shown in
Fig. 4. Assemble and install accessory roof curb in accordance
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. 4. Improperly applied gasket can also result in air leaks and
poor unit performance.
Curb should be level. This is necessary for unit drain to func-
tion properly. Unit leveling tolerances are show in Fig. 5. Refer
to Accessory Roof Curb Installation Instructions for additional
information as required.
