AIR ConDItIonER InStAllAtIon
General Information
The S5BP 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.
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.
• Overhead obstructions (Figure 1), poorly ventilated
areas, and areas subject to accumulation of debris
should be avoided.
• Sufficient clearance for unobstructed airflow through
the outdoor coil must be maintained in order to
achieve rated performance. For minimum clearances
to obstructions, see Figure 1.
• Consideration to minimum clearances should be
given to availability of electric power, service access,
noise, and shade.
Packaging Removal
Locate and remove all screws securing the unit to the
shipping skid.
notE: To prevent damage to the tubing
connections, carefully remove the carton and user’s
manual from the equipment. Discard the shipping carton.
Rigging & Hoisting
WARnInG:
to avoid the risk of property damage, personal
injury, or death, it is the rigger’s responsibility
to ensure that whatever means are used to hoist
the unit are safe and adequate:
• the lifting equipment must be adequate for
the load. Refer to table 3 (page 10) for unit
weights.
• the unit must be lifted from the holes in the
base rails using cables or chains.
• Spreader bars are required to protect the unit
and ensure even loading.
• Keep the unit in an upright position at all times.
• All panels must be securely in place during
rigging and hoisting.
Rooftop
Rooftop installations must be located according to local
building codes or ordinances and these requirements:
• Units may be installed on Class A, B, or C roof
covering material.
• The roof must be capable of handling the weight of
the unit. Reinforce the roof if necessary. Support
must be made of weather resistant materials and
installed prior to unit installation. For unit weights,
see Table 3 (pg. 10).
• Secure optional mounting pad or frame to roof using
acceptable mechanical methods per local codes.
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 must be provided and be separate
from the building foundation. The pad must be level and
strong enough to support the unit’s weight. The slab
height must be a minimum of 2” (5 cm) above grade and
provide adequate drainage. See Figure 1.
Connecting Refrigerant tubing Between the Indoor
& outdoor unit
CAutIon:
this system uses R-410A refrigerant with PoE
oil. 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.
