DESCRIPTION

The HRA 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
applications to provide a complete system. Electric Heaters
are available if required. Add-On coils are available for use
with upflow, downflow or horiz ont al fur naces and ai r handle rs.

FEATURES

• QUALITY CONDENSER COILS - The coil is constructed
of enhanced copper tube and aluminum fins.

• COIL PROTECTION - Coils are protected from dam age 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
protects the compressor if undesirable operating condi­tions occur. A liquid line filter-drier further protects the
compressor.

• 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.
Special primer formulas and matted-textured finish insure
less fading when exposed to sunlight.

• LOWER INSTALLED COST - Installation time and costs
are reduced by e asy p ower and contro l wi ring c onnec tions.
Discharge line heat exchanger knockouts are provided, 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 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 mou nted c ompre ssor a nd the ripple d fins of
the condenser coil muffle the normal fan motor and com­pressor operating sounds.

• LOW MAINTENANCE - Long life perm anently lubricated
motor-bearings need no annual servicing.

• EASY SERVICE ACCESS - Fully exposed refrigerant c on­nections, a single panel covering the electrical controls
and the molex plug in the control box connecting the con­denser 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.

• FACTORY TESTED - to verify system operation and con-
trol functioning before shipment.

Cooling 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 blower motor.
EER (Energy Efficiency Ratio) is the total cooling output in BTU’s at a 95°F outdoor ambient divided by the total electric power in watt-hours at

those conditions.
SEER (Seasonal Energy Efficiency Ratio) is the total cooling output in BTU’s during a normal annual usage period for cooling divided by the

total electric power
input in watt-hours during the same period.

1.

TXV = Thermal Expansion Valve kit required. Use 1TV700 series kit.

2.

Single phase units require single phase 2HK heaters — Three phase units require three phase 2HK heaters. (29) indicates 460 volt use only.

3.

G2FD coils available with a factory installed horizontal drain pan. Replace “S” with “H” in the model number.
