Locating the Air Conditioner

• Survey the job site to determine the best location for
mounting the outdoor unit. Select a solid, level position,
preferably on aconcrete slab, slightly above the grade
level, and parallel to the home. If possible, select a site
for the unit that is as close as possible to the proposed
return grille location. DO NOT PLACE UNIT UNDER

THE HOME.

• The unit should be located with consideration of
minimizing the length of the supply and return ducts.

If practical, place the air conditioner and its ducts in
an area where they will be shaded from the afternoon
sun, when the heat load is greatest.

• The length of the supply and return ducts should be
kept to a minimum with no sharp radius bends.

• Overhead obstructions, poorly ventilated areas, and
areas subject to accumulation of debris should be
avoided. The hot condenser air must be discharged
up and away from the home, and if possible, in a
direction with the prevailing wind. Do not place the unit
in a confined space. See Figure 10 (page 13) for unit

dimensions.

Air Duct System
Air ducts must be installed in accordance with the standards

of the National Fire Protection Association "Standard for
Installation of Air Conditioning and Ventilation Systems"

(NFPA 90A), "Standard for Installation of Residence Type
Warm Air Heating and Air Conditioning Systems" (NFPA
90B), these instructions, and all applicable codes. NFPA
publications are available by writing to: National Fire
Protection Association, Batterymarch Park, Quincy, ME
02269 or visit www.NFPA.org on the web.

• Design the duct work according to methods described
by theAir Conditioning Contractors of America (ACCA).

• The supply duct system, including the number and
type of registers, will have much more effect on the
performance of the system than any other factor. The
duct must be sufficiently large to conduct an adequate
amount of air to each register. See Figure 3 (page 6).

SINGLE DUCT APPLiCATiON MULTIPLE DUCT APPLiCATiON

Figure 3. Single & Multiple Duct Applications

• Ductworkshould be attached directlytothe unitflanges
for horizontal applications,

• For highly resistive duct systems it may be necessary
to add an additional return air duct and or supply to
achieve maximum performance and prevent coil icing
and refrigerant flood back.

• The heat purnpsysternwill notcool or heatthe home
if air is lost to the outside through leaks in the duct
system. Ducts that are collapsed or restricted by
foreign objects will also prevent adequate air flow,

• All duct work passing through unconditioned space
must be properly insulated to minimize duct losses
and prevent condensation. Use insulation with an outer
vapor barrier. Refer to local codes for insulation material
requirements,
