AIR CONDITIONER INSTALLATION

General Information

The *SA1BF4M2SN series air conditioner is designed only 

for outdoor rooftop or ground level installations. 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. The system must be wired 

and provided with circuit protection in accordance with 

local building codes. If there is any question concerning 

the power supply, contact the local power company.

  The indoor section (air handler, furnace, etc) should be 

installed before routing the refrigerant tubing. Refer to the 

indoor unit's installation instructions for installation details.

  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.

•  The outdoor unit should be installed no closer than 18 

inches from the outside walls of the facility and in an area 

free from overhead obstructions to ensure unrestricted 

airflow through the outdoor unit.

•  Sufficient clearance for unobstructed airflow through the 

outdoor coil must be maintained in order to achieve rated 

performance. See 

Figure 1

 for minimum clearances to 

obstructions.

•  Overhead obstructions (

Figure 1

), poorly ventilated areas, 

and areas subject to accumulation of debris should be 

avoided.

•  Consideration should be given to availability of electric 

power, service access, noise, and shade.

Packaging Removal

NOTE: 

To prevent damage to the tubing connections, carefully 

remove the carton and user’s manual from the equipment. 
Discard the shipping carton.

Ground Level

Ground level installations must be located according to local 

building codes or ordinances and these requirements:

•  Clearances must be in accordance with those shown in 

Figure 1

.

•  A suitable mounting pad (

Figure 1

) must be provided and 

separate from the building foundation. The pad must be 

level and strong enough to support the weight of the unit. 

The slab height must be a minimum of 2” (5 cm) above 

grade and with adequate drainage.

Roof Mount

•  The method of mounting should be designed so that it 

does not overload roof structures or transmit noise to 

the interior of the structure. The roof must be structurally 

capable of handling the weight of the unit.

•  Full perimeter support is required under the unit. Support 

must be made of weather resistant materials and installed 

prior to unit installation.

•  The support must be built to raise the unit 6" above the 

roof.

Connecting Refrigerant Tubing Between the Indoor 

& Outdoor Unit

 CAUTION:

When servicing, cover or seal openings to 

minimize the exposure of the refrigerant system 

to air to prevent accumulation of moisture and 

other contaminants.

After outdoor and indoor unit placement has been determined, 

route refrigerant tubing between the equipment in accordance 

with sound installation practices.
