This Single Package Gas Heating / Electric Cooling

Unit is designed for outdoor rooftop or ground level

slab installations and can be readily connected to the

duct system of a home or building. 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. Verify

coil ﬁns are straight. If necessary, comb ﬁns to remove

ﬂattened or bent ﬁns. 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

• 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.

• Sufcientclearanceforunobstructedairow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.

• 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 clearances are greater than

minimumclearancestocombustibles,accessibility

clearancesmusttakepreference.

• 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.
