Bryant’s Air Conditioners with Puron® refrigerant provide a col-
lection of features unmatched by any other family of equipment.
The 550A family has been designed utilizing Bryant’s Puron
refrigerant. The environmentally sound refrigerant allows you to
make a responsible decision in the protection of the earth’s
ozone layer. Bryant’s 550A system meets the Energy Star®
guidelines for energy efficiency.
FEATURES
Puron Environmentally Sound Refrigerant —Is Bryant’s
refrigerant designed to help protect the environment. Puron is
an HFC refrigerant which does not contain chlorine that can
harm the ozone layer. The most important advantage of Puron
refrigerant is that it has not been banned in future air condition-
ing systems as the traditional refrigerant R-22 has been. Puron
refrigerant is in service in thousands of systems proving highly
reliable, environmentally sound performance.
Bryant’s Evolution™ Controls —These industry-leading con-
trols, when installed with Bryant’s Perfect Humidity™ variable-
speed furnaces or fan coils, provide the homeowner with:
–unparalleled control of temperature, humidity, indoor air quality,
and zoning
–unprecedented ease of use
–simple operation through on-screen, text-based service
reminders
Optional remote access through telephone or Internet is also
available when combined with a remote connectivity kit.
Heavy Duty Inlet Grille —The DuraGuard™ coil protector,
made of a coated steel wire grid with vertical 3/8 in. spacing, is
designed to help protect the coil from inclement weather, van-
dalism, and incidental damage. It provides protection while not
restricting airflow and maintaining ease of coil inspection and
cleaning.
High Efficiency Performance —Is delivered through a combi-
nation of features including Bryant’s Puron refrigerant, unique
scroll compressor, and advanced heat transfer surfaces. Effi-
ciency ratings are 13 SEER (Seasonal Energy Efficiency
Ratio) with enhanced ratings of up to 14.5 SEER. Sophisti-
cated heat transfer surfaces utilized in Bryant’s 550A design
allow heat to easily be transferred to the outdoor air and
require less energy. The unique scroll compressor found in the
550A design performs quietly and adds to the overall efficiency
of the system. For improved serviceability, all models are
equipped with a compressor terminal plug. Finally, Bryant’s
Puron refrigerant operates more efficiently than ordinary R-22
refrigerant found in other systems. The efficiency levels pro-
vided by the 550A provide end users with lower costs of opera-
tion than traditional air conditioning systems.
Assured Future Service —By utilizing the environmentally
sound refrigerant, Puron, 550A models will remain serviceable
well into the future. The Clean Air Act of 1990 has placed a cap
on production of most other refrigerants which has scheduled
reductions beginning in 2004. The resulting cap in production
ultimately results in a complete ban on many other refrigerants
in new equipment by the year 2010. These changes required by
federal law, mean the supply of other refrigerants may be limited
in the near future making Puron refrigerant the correct choice
when considering long term serviceability.
Highly Reliable Performance —Is delivered through the supe-
rior design of the system and componentry. The reliability of
the 550A models has been proven to provide the lowest inci-
dence of warranty service of any product in the Bryant family
in the past three years of service. Long term reliability is
assured through the use of both high and low pressure
switches which will not allow the system to operate in the
event of a significant change in operating pressure. In doing
this, the system is protected from damage if an unusual condi-
tion arises. Finally, Bryant includes a special liquid line filter
drier designed to trap moisture and contaminants which could
otherwise shorten the life of the system.
Bryant’s AeroQuiet System —Is one of the most sought after
features of the 550A family. Extremely low operating sound is the
result of special attention to the air moving through the outdoor
unit, a specially designed sound enclosure surrounding the com-
pressor, and an exclusive laminated plate beneath the compres-
sor to eliminate sound transmission to the rest of the system.
Application Versatility —Bryant’s systems utilizing Puron
refrigerant have the same application guidelines as other sys-
tems. Applications which include long line sets (50 to 175 ft) or
applications which require the system to operate at low outdoor
temperatures (below 55°F) are approved under Bryant’s stan-
dard guidelines.
Bryant Coils and Fan Coils to Complete the System —Bryant
specially designs both the outdoor product and indoor coil prod-
ucts to operate with assured reliability and performance. A wide
range of indoor coil options are listed in the ratings sections of
this publication.
Special Protective Devices —High and low pressure switches
and internal protection in the compressor including temperature
and current sensing overloads prevent operation under poten-
tially damaging circumstances. A special liquid line filter drier
designed to trap nearly 4 times the volume of contaminants of
standard driers provides superior protection from moisture
trapped in the system.
Electrical Range —208/230v, single phase.
Wide Range of Sizes —Available in six sizes; 2, 2-1/2, 3, 3-1/2,
4, and 5 ton.
Cabinet —Galvanized steel is coated with powder paint to pro-
vide superior long-lasting protection and appearance.
Totally Enclosed Fan Motor —Protected from adverse weather
conditions.
Unit Design —Enhanced copper and aluminum heat transfer
surfaces with vertical air discharge to direct air up and away
from the area.
External Service Valves —Both service valves are back seating
type valves which are externally located. These unique valves
allow service technicians to evacuate or charge the system in
less time than standard service valves.
Easy Serviceability —Removal of one panel provides access to
both electrical and refrigerant carrying components simplifying
installation and service.
Agency Approvals —550A models are listed with UL (U.S. and
Canada), ARI, and CEC. Special endorsements have also been
awarded these products by Energy Star® which recognizes
energy efficient products.
Limited Warranty —A standard five year warranty on parts
with extended warranty coverage on the compressor for a
total of 10 years. A five year warranty is offered on the out-
door coil. Optional warranties are available through your
Bryant distributor.
