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 conditioning 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 controls, 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, vandalism, 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 combination of features including Bryant’s Puron refrigerant, unique scroll compressor, and advanced heat transfer surfaces. Efficiency ratings are 13 SEER (Seasonal Energy Efficiency Ratio) with enhanced ratings of up to 14.5 SEER. Sophisticated 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 provided by the 550A provide end users with lower costs of operation 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 superior design of the system and componentry. The reliability of the 550A models has been proven to provide the lowest incidence 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 condition 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 compressor, and an exclusive laminated plate beneath the compressor 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 systems. 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 standard guidelines. Bryant Coils and Fan Coils to Complete the System—Bryant specially designs both the outdoor product and indoor coil products 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 potentially damaging circumstances. A special liquid line filter drier designed to trap nearly 4 times the v...
