freight bill. Damage claims should be filed with carrier
immediately. Claims of shortages should be filed with the
seller within 5 days.
NOTE: If any damages are discovered and reported to the
carrier, do not install the unit because your claim may be
denied.
 Location
 The blower section should be centered in its locations and
may be installed in a closet, alcove, utility room, base-
ment, crawl space or attic. Minimum clearances must be
met.
 If the unit is installed in an unconditioned space such as
an attic or crawl space, you must ensure that the area
provides sufficient air circulation to prevent moisture
collections on the cabinet during high dew point condi-
tions.
 Ductwork
 Install the conditioned air plenum, ducts and air filters
(not provided) in accordance with NFPA 90B Standard for
the installation of Warm Air Heating and Air-Conditioning
Systems (latest edition).
 Air filters must be listed as Class 2 furnace air filters.
 Supply and return ductwork must be adequately sized
to meet the system’s air requirements and static
pressure capabilities. Ductwork should be insulated
with a minimum of 1” thick insulation with a vapor
barrier in conditioned areas or 2” minimum in uncondi-
tioned areas.
 If installing the blower section without an evaporator
coil, the supply plenum should be the same size as the
flanged opening provided around the blower outlet and
should extend ideally at least 3 ft. from the blower
section before turning or branching off plenum into duct
runs. The plenum forms an extension of the blower
housing and minimizes air expansion losses from the
blower.
