Place the unit on a solid, level pad that is at least 2 in. (51 mm)
above grade. The pad should extend approximately 2 in. (51 mm)
beyond the casing on all 4 sides of the unit. Do not secure the unit
to the pad except when required by local codes.
Step 3 — Field Fabricate Ductwork
Secure all ducts to roof curb and building structure on vertical
discharge units. Do not connect ductwork to unit. For horizontal
applications, unit is provided with flanges on the horizontal
openings. All ductwork should be secured to the flanges. Insulate
and weatherproof all external ductwork, joints, and roof openings
with counter flashing and mastic in accordance with applicable
codes.
Ducts passing through an unconditioned space must be insulated
and covered with a vapor barrier.
If a plenum return is used on a vertical unit, the return should be
ducted through the roof deck to comply with applicable fire codes.
Read unit rating plate for any required clearances around ductwork.
Cabinet return- -air static shall not exceed - -.25 IN. W.C.
Step 4 — Provide Clearances
The required minimum operating and service clearances are shown
in Fig. 2 and 3.

(1219 mm).
Do not place the unit where water, ice, or snow from an overhang
or roof will damage or flood the unit. Do not install the unit on
carpeting or other combustible materials. The unit may be installed
on wood flooring or on Class A, B, or C roof covering materials.
