DESCRIPTION
The heat pump condensing unit is the outdoor part of a versatile
system of heating and air conditioning. It is designed to be cus-
tom-matched with one of UPG's complete line of evaporator
sections, with each serving a specific function. Matching Air
Handlers are available for upflow, downflow, or horizontal appli-
cations 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
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 pres-
sure relief valve and a temperature sensor which protects the
compressor if undesirable operating conditions occur. A liq-
uid 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 finish insure
less fading when exposed to sunlight.
• LOWER INSTALLED COST - Installation time and costs are
reduced by easy power and control wiring connections.
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 landscaping.
This allows compact location on multi-unit applications.
• 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. Iso-
lator mounted compressor and the rippled fins of the con-
denser 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 controls
make for easy servicing of the unit.
