Before You Install this Unit
The cooling load of the area to be conditioned
must be calculated and a system of the proper
capacity selected. It is recommended that the
area to be conditioned be completely insulated
and vapor sealed.
Check the electrical supply and verify the
power supply is adequate for unit operation.
If there is any question concerning the power
supply, contact the local power company.
All units are securely packed at the time of
shipment and upon arrival should be carefully
inspected for damage prior to installing the
equipment at the job site. Verify coil fi ns are
straight. If necessary, comb fi ns to remove
fl attened or bent fi ns. Claims for damage
should be fi led immediately with the carrier.
Please consult your dealer for maintenance
information and availability of maintenance
contracts. Please read all instructions before
installing the unit.
Locating the Heat Pump
• Survey the job site to determine the best
location for mounting the outdoor unit. Select
a solid, level position, preferably on a concrete
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 heat pump 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
confi ned space. See Figure 9 & Table 4 (page
13) for unit dimensions.
• Suffi cient clearance for unobstructed airfl ow
through the outdoor coil must be maintained
in order to achieve rated performance. See
Figure 2 (page 5) for minimum clearances to
obstructions.
• Consideration should also be given to
availability of electric power, service access,
noise, and shade.
