GENERAL INFORMATION

This packaged air conditioner is designed only for outdoor 
ground level 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. 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 
mechanical skills and tools.

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 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.

  Please consult your dealer for maintenance information 

and availability of maintenance contracts. Please read 
all instructions before installing the unit.

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 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 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 9 (page 12) for unit 
dimensions.

•  Sufficient clearance for unobstructed airflow through 

the outdoor coil must be maintained in order to achieve 
rated performance.

•  Consideration should also be given to availability of 

electric power, service access, noise, and shade.

Minimum Clearance Requirements

Sufficient clearance for unobstructed airflow through the 
outdoor coil must be maintained in order to provide room 
for proper servicing and achieve rated performance. See 
Figure 1 for minimum clearances to obstructions.

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 the Air 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 2 (page 5).
