N No otte ess::
• For units with optional Condensate
Overflow Switch (COF) accessory kit, the
switch will not work properly if unit is not
level or slightly sloped toward switch.
• To assure proper condensate flow during
operation the unit and the curb must be
level.
If the unit is installed at ground level, elevate it above
the snow line. Provide concrete footings at each
support location with a “full perimeter” support
structure or a slab foundation for support. Refer to
Table 1, p. 13 for the unit’s operating and point loading
weights when constructing a footing foundation.
If anchoring is required, anchor the unit to the slab
using hold down bolts or isolators. Isolators should be
installed to minimize the transmission of vibrations
into the building.
For rooftop applications, if anchoring is required,
anchor the unit to the roof with hold-down bolts or
isolators.
Check with a roofing contractor for proper
waterproofing procedures.
Ductwork
Elbows with turning vanes or splitters are
recommended to minimize air noise due to turbulence
and to reduce static pressure.
When attaching the ductwork to the unit, provide a
watertight flexible connector at the unit to prevent
operating sounds from transmitting through the
ductwork.
All outdoor ductwork between the unit and the
structure should be weather proofed after installation is
completed.
N No otte e:: For sound consideration, cut only the holes in the
roof deck for the ductwork penetrations. Do not
cut out the entire roof deck within the curb
perimeter.
If a Curb Accessory Kit is not used:
1. The ductwork can be attached directly to the
factory-provided flanges around the unit’s supply
and return air openings. Be sure to use flexible duct
connections at the unit.
2. For “built-up” curbs supplied by others, gaskets
must be installed around the curb perimeter flange
and the supply and return air opening flanges.

The checklist listed below is a summary of the steps
required to successfully install a commercial unit. This
checklist is intended to acquaint the installing
personnel with what is required in the installation
process. It does not replace the detailed instructions
called out in the applicable sections of this manual.
☐ Check the unit for shipping damage and material
shortage; file a freight claim and notify appropriate
sales representative.
☐ Verify correct model, options and voltage from
nameplate.
