DESCRIPTION
The 12 SEER Series condensing unit is the outdoor
part of a versatile system of air conditioning. It is
designed to be custom-matched with one of UPG’s
complete line of evaporator sections, each designed to
serve a specific function. Matching Air Handlers are
available for upflow, downflow or horizontal applica-
tions to provide a complete system. Electric Heaters
are available if required. Add-On coils are available for
use with upflow, downflow or horizontal furnaces and
air handlers.
WARRANTY
5-year limited parts warranty.
10-year limited compressor warranty.
FEATURES
• QUALITY CONDENSER COILS - The coil is constructed
of enhanced copper tube and aluminum fins.
• COIL PROTECTION - Coils are protected from damage by
a polymer mesh applied between the coil face, and a PVC
coated steel coil guard.
• PROTECTED COMPRESSOR - The compressor is inter-
nally protected against high pressure and temperature.
This is accomplished by the simultaneous operation of
high pressure relief valve and a temperature sensor which
protects the compressor if undesirable operating condi-
tions occur. A liquid line filter-drier further protects the
compressor.
• DURABLE FINISH - The cabinet is made of pre-painted
steel. The pre-treated galvanized steel provides a better
paint to steel bond, which resists corrosion and rust creep.
Special primer formulas and matted textured champagne
finish insure less fading when exposed to sunlight.
• LOWER INSTALLED COST - Installation time and costs
are reduced by easy power and control wiring connec-
tions. Discharge line heat exchanger knockouts are pro-
vided, if required. Available in sweat connect models only.
The unit contains enough refrigerant for matching indoor
coils and 15 feet of interconnecting piping. The small base
dimension means less space is required on the ground or
roof.
• TOP DISCHARGE - The warm air from the top mounted
fan is blown up away from the structure and any landscap-
ing. This allows compact location on multi-unit applica-
tions.
• LOW OPERATING SOUND LEVEL - The upward air flow
carries the normal operating noise up away from the living
area. The rigid top panel effectively isolates any motor
sound. Isolator mounted compressor and the rippled fins
of the condenser coil muffle the normal fan motor and
compressor operating sounds.
• LOW MAINTENANCE - Long life permanently lubricated
motor-bearings need no annual servicing.
• EASY SERVICE ACCESS - Fully exposed refrigerant con-
nections, a single panel covering the electrical controls
and the molex plug in the control box connecting the con-
denser fan, make for easy servicing of the unit.
• SECURED SERVICE VALVES - Secured re-usable ser-
vice valves are provided on both the liquid and vapor
sweat connections for ease of evacuating and charging.
• U.L. and C.U.L. listed - approved for outdoor application.
Certified in accordance with the Unitary Small Equipment cer-
tification program, which is based on ARI Standard 210/240.
