GENERAL INFORMATION
This single package gas heating / electric cooling unit is
designed only for outdoor rooftop or ground level slab
installations and can be readily connected to the high static duct
system of a home. This unit has been tested for capacity and
efficiency in accordance with AHRI standards and will provide
many years of safe and dependable comfort, providing it is
properly installed and maintained. With regular maintenance,
this unit will operate satisfactorily year after year. Abuse,
improper use, and/or improper maintenance can shorten the
life of the appliance and create unsafe hazards.
To achieve optimum performance and minimize equipment
failure, it is recommended that periodic maintenance be
performed on this unit. The ability to properly perform
maintenance on this equipment requires certain tools and
mechanical skills.
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. Consideration should be given
to availability of electric power, service access, noise, and
shade. 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. Claims for damage
(apparent or concealed) should be filed immediately with
the carrier.
√ Survey the job site to determine the best location for setting
the unit. Choose an appropriate location that minimizes the
length of the supply and return air ducts.
√ Please consult your dealer for maintenance information
and availability of maintenance contracts. Please read all
instructions before installing the unit.
Locating the Equipment
• Clearance in accordance with local installation codes, the
requirements of the gas supplier and the manufacturer's
installation instructions.
• Dégaugement conforme aux codes d'installation locaux,
aux exigences du fournisseur de gaz et aux instructions
d'installation du fabricant.
• A clearance of at least 36 inches from the blower access
panel and from the louvered control access panel is
recommended for servicing and maintenance. Where
accessibility to combustibles clearances are greater
than minimum clearances, accessibility clearances
must take preference.
• Select a solid, level position, preferably on a concrete slab,
slightly above the grade level, and parallel to the home. DO
NOT PLACE UNIT UNDER THE HOME.
• Overhead obstructions, poorly ventilated areas, and areas
subject to accumulation of debris should be avoided. Do not
place the unit in a confined space or recessed area where
discharge air from the unit to re-circulate into the condenser
air inlet, through the coil.
• Sufficient clearance for unobstructed airflow through the
louvered control access panel and outdoor coil must be
maintained in order to achieve rated performance. See
Figure 1
for minimum clearances to obstructions.
• The hot condenser air must be discharged up and away from
the home, and if possible, in a direction with the prevailing
wind.
• 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.
Heating Load
This unit should be sized to provide the design heating
load requirement. Heating load estimates can be made
using approved methods available from Air Conditioning
Contractors of America (Manual J); American Society of
Heating, Refrigerating, and Air Conditioning Engineers; or other
approved engineering methods. For installations above 2,000
ft., the unit should have a sea level input rating large enough
that it will meet the heating load after deration for altitude.
