Installation of this product should follow all manufacturer’s refrigerant charging and air flow instructions. Failure to confirm proper charge and air flow may reduce energy efficiency and shorten equipment life. 548J548J TABLE OF CONTENTS PAGE PAGE FEATURES AND BENEFITS .................... 3 MODEL NUMBER NOMENCLATURE ............ 4 FACTORY OPTIONS & ACCESSORIES ........... 5 ARI CAPACITY RATING ....................... 8 SOUND PERFORMANCE ....................... 9 PHYSICALDATA ............................. 10 WEIGHTS&DIMENSIONS .................... 18 APPLICATIONDATA ......................... 24 COOLINGTABLES ........................... 26 STATICPRESSURETABLES ................... 35 FANPERFORMANCE ......................... 36 OUTDOOR AIR INTAKE & EXHAUST PERF ..... 46 ELECTRICALINFO ........................... 47 MCA/MOCP ................................ 49 TYPICALWIRINGDIAGRAMS ................ 61 GUIDESPECIFICATIONS ...................... 68 Your Bryant Packaged Heat Pump 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 and easy to use. Easy to install: All Legacy Linet units are field- --convertible to horizontal air flow; no special adapter curbs or kits are necessary. Convertible airflow design makes it easy to adjust to unexpected job- --site complications. Lighter units make easy replacement. Bryant 3- --8.5 ton 548J 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. Take accurate pressure readings by reading condenser pressure with panels on. Simply remove the black, composite plug, route your gauge line(s) through the hole, and connect them to the refrigeration service valve(s). Now, you can take refrigeration system pressure readings without affecting the condenser airflow. Easy to use: The newly designed, master terminal board by Bryant 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. Bryant rooftops have high and low pressure switches, a filter drier, and 2” (51mm) filters standard. 2 FEATURES AND BENEFITS S Up to 28% lighter than similar industry units. Lighter rooftops make easier replacement jobs. S 3- --8.5 ton units fit on existing Bryant rooftop curbs making the utility connections the same. This saves time and money on replacement jobs. S Standardized components and layout. Standardized components and controls make service and stocking parts easier. S Scroll compressors on all units. This makes service, stocking parts, replacement, and trouble- --shooting easier. S Crankcase heater on all models (except 04 size) provides added protection in all applications. S Precession sized suction line accumulator provide high reliability by preventing liquid from entering the compressor during low ambient conditions and reverse cycle switch over. S Field convertible airflow (3- --8.5 tons). Being able to convert a unit from vertical airflow to horizontal makes it easy to overcome job site complications. S 4- --way reversing valve rapidly changes the flow of refrigerant to quickly changeover from cooling to heating and heating to cooling. S 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. S 3- --5 ton models come standard with an Electric Drive X13, 5 speed/torque motor to provide exact performance in many applications. Belt drive motor optional. S Provisions for bottom or side condensate drain. S Capable of thru- --the- --base or thru- --the- --curb electrical routing. S Dependable time/temperature defrost logic provides a defrost cycle, if needed, every 30, 60, 90 or 120 minutes and is adjustable. S Single- --point electrical connection. S Sloped, composite drain pan. Sloped, composite drain pan sheds water; and won’t rust. S Standardized controls and control box layout. Standardized components and controls make stocking parts and service easier. S Clean, easy to use control box. S Standard coils are copper round tube, aluminum plate fin with optional coil coatings and copper fin design. S Color- --coded wiring. S Large, laminated wiring and power wiring drawings which are affixed to unit make troubleshooting easy. S Single, central terminal board for test and wiring connections. S Fast- --access, handled, panels for easy access to the blower and blower motor, control box, and compressors. S “No- --s...
