DESCRIPTION
The heat pump condensing unit is the outdoor part of a versa-
tile system of heating and air conditioning. It is designed to be
custom-matched with one of UPG's complete line of evapora-
tor sections, with each serving a specific function. Matching
Air Handlers are available for upflow, downflow, or horizontal
applications 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 han-
dlers.
WARRANTY
Single Phase Units:
5-year limited parts warranty.
5-year limited compressor warranty.
FEATURES
• QUALITY CONDENSER COILS - The coil is constructed
of copper tubing and enhanced aluminum fins for
increased efficiency and corrosion protection.
• PROTECTED COMPRESSOR - The compressor is inter-
nally protected against high pressure, temperature, and
externally by a factory installed high pressure switch. This
is accomplished by the simultaneous operation of high
pressure relief valve and a temperature sensor which pro-
tects the compressor if undesirable operating conditions
occur. A liquid line filter-drier further protects the compres-
sor.
• 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 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. Available in sweat connect models only. The unit
contains enough refrigerant for matching indoor coils and
15 feet of interconnecting piping. The small base dimen-
sion 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 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, and a single panel covering the electrical con-
trols 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.
