549J Preferred Single-Packaged Heat Pump Rooftop Units, High Efficiency, with Puron® (R-410A) Refrigerant

Bryant Preferred™ Series 3 to 10 Ton rooftop unit (RTU) was designed by customers for customers. With “no-strip” screw collars,
handled access panels, and more, we’ve made your unit easy to install, easy to maintain, easy to use and reliable.
Easy to install:
All Preferred™ Series units are field-convertible to horizontal air flow with no special kit required on 04-09 models. Supply duct kit
is required for size 12 only. Convertible airflow design makes it easy to adjust to unexpected job site complications. Lighter units
make easy replacement. Bryant 3 to 10 ton 549J rooftops fit on existing Bryant curbs dating back to 1989. Also, our large control box
gives you room to work and room to mount Bryant accessory controls.
Easy to maintain:
Easy access handles by Bryant provide quick and easy access to all normally serviced components. Our “no-strip” screw system has
superior holding power and guides screws into position while preventing the screw from stripping the unit’s metal.
Easy to use:
The central terminal board puts all your connections and troubleshooting points in one convenient place, standard. Most low voltage
connections are made to the same board and make it easy to find what you’re looking for and easy to access it.
Reliable:
Each unit comes with precision sized and tested scroll compressor that is internally protected from over temperature and pressures.
Each refrigerant circuit is further protected with a high pressure, loss of charge and freeze protection switch. In addition, a liquid line
filter drier and suction line accumulator protects each circuit. Each unit is factory tested prior to shipment to help ensure units operation once properly installed.

Key features are:
• Up to 28% lighter than similar industry units. Lighter rooftops make easier replacement jobs.
• SEER up to 15.8, EER up to 12.8.
• IEER up to 14.0 with single speed indoor fan motor and up to 15.6 with 2-speed/VFD indoor fan motor.
• 3 to 10 ton units fit on existing Bryant rooftop curbs, which saves time and money on replacement jobs.
• Standardized components and layout. Standardized components and controls make service and stocking parts easier.
• Scroll compressors on all units. This makes service, stocking parts, replacement, and troubleshooting easier.
• Crankcase heater on all models (except 04 size) provides added protection in all applications.
• Precision-sized refrigerant suction line accumulator provides high reliability by preventing liquid from entering the compressor
during low ambient conditions and reverse cycle switch over.
• Field convertible from vertical to horizontal airflow on all models. No special kits required on 04-09 models. Supply duct kit
required for 12 size model only.
• 4-way reversing valve rapidly changes the flow of refrigerant to quickly changeover from cooling to heating and heating to cooling.
• Easy-adjust, belt drive motor available on all sizes. Bryant provides a factory-solution for most points in the fan performance
table. There’s no need for field-supplied drives or motors.
• 3 to 5 ton models come standard with a Direct Drive X13, 5 speed/torque motor to provide exact performance in many applications. Belt drive motor optional on all three phase voltage models.
• Provisions for bottom or side condensate drain.
• Capable of thru-the-base or thru-the-curb electrical routing.
• Dependable time/temperature defrost logic provides a defrost cycle, if needed, every 30, 60, 90 or 120 minutes and is adjustable.
• Single-point electrical connection.
• Sloped, composite drain pan sheds water; and won’t rust.
• Standardized controls and control box layout. Standardized components and controls make stocking parts and service easier.
• Clean, large, easy to use control box.
• Standard coils are copper round tube, aluminum plate fin with optional coil coatings and copper fin design.
• Large, laminated wiring and power wiring drawings which are affixed to unit make troubleshooting easy.
• Single, central terminal board for test and wiring connections.
• Fast-access, handled, panels for easy access to the blower and blower motor, control box, and compressors.
• “No-strip” screw system guides screws into the panel and captures them tightly without stripping the screw, the panel, or the unit.
• Exclusive, newly-designed indoor refrigerant header for easier maintenance and replacement.
• Standard mechanical cooling (125°F to 30°F or 52°C to –1°C).
• 2-in. (51mm) disposable filters on all units.
• High capacity refrigerant filter drier and TXV metering device on each circuit.
• High pressure switch, loss of charge switch and freeze protection adds greater unit reliability.
• Optional 2-Speed Indoor Fan Motor System utilizes a Variable Frequency Drive (VFD) to automatically adjust the indoor fan
motor speed between cooling stages. Available on 2-stage cooling model sizes 07-12 with electro-mechanical controls or
RTU Open controller 549J.
