ntt:: Refer to local building codes for proper

installation. All installation must comply
with local building codes.

Horizontal Units

N

No

otte

ess::

For complete step by step instructions on
how to install a Horizontal Conversion Kit,
please refer to ACCSVN159*- EN.

For units with optional Condensate
Overflow Switch (COF) , 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. 16

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.
