DESCRIPTION
The HDA Series condensing unit is the outdoor part of a versatile system of air conditioning. It is designed to be custommatched 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
application to provid e a com plete syste m. Elec tric he aters a re
available if required.
FEATURES
• QUALITY CONDENSER COILS - The coil is con structed
of enhanced copper tube and aluminum fins.
• COIL PROTECTION - Coils are protected fro m dama ge by
a polymer mesh applied between the coil face, and a PVC
coated steel coil guard.
• PROTECTED COMPRESSOR - The compressor is internally protected against high pressure and temperature.
This is accomplished by the simultaneous operation of
high pressure relief valve and a temperature sensor which
protect the compressor if undesirable operating conditions
occur.
• DURABLE FINISH - Cabinet is made of pre-painted steel.
The pre-treated flat galvanized steel provides a better
paint to steel bond, which resists corrosion and rust creep.
Specia l pri me r form ulas and glossy earth tone finish insure
less fading when exposed to sunlight.
• LOWER INSTALLED COST - Installation time and costs
are reduced by easy power and control wiring connections. Discharge line heat exchanger knockouts are provided, if required. Both quick connect and sweat connect
models are availabl e. Bo th s erv ic e v al ve s a re fi rml y a ffixed
to the unit. The sweat 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 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 connections and a single pan el cov eri ng the electrical controls
make servicing easy.
• 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.
• FACTORY TESTED - to verify system operation and con-
trol functioning before shipment.

1 & 3 PHASE HDA WITH N1AH AIR HANDLER & G2FD COILS
MBH based on 80°F entering air temperature, 50% RH, and rated air flow.
KW includes compressor, outdoor fan and indoor blower motor watts. Add-on coils include 365 watts/1000 CFM for blo wer motor.
SEER (Seasonal Energy Efficiency Ratio) is the total cooling output in BTUs during a normal annual usage period for cooling divided
by the total electric power input inwatt-hours during the same period.
(EER) = Energy Efficiency Ratio-steady state total BTUH/electric power input.
