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. 558J558J TABLE OF CONTENTS PAGE PAGE FEATURES AND BENEFITS .................... 3 MODEL NUMBER NOMENCLATURE ............ 4 FACTORY OPTIONS & ACCESSORIES ........... 5 ARI CAPACITY RATING ....................... 8 SOUNDPERFORMANCE ...................... 10 PHYSICALDATA ............................. 11 BASEUNITDIMENSIONS ..................... 16 APPLICATIONDATA ......................... 18 COOLINGTABLES ........................... 20 STATICPRESSURETABLES ................... 24 FANPERFORMANCE ......................... 25 OUTDOOR AIR INTAKE & EXHAUST PERF ..... 33 ELECTRICALINFO ........................... 34 MCA/MOCP ................................ 36 TYPICALWIRINGDIAGRAM .................. 45 GUIDESPECIFICATIONS ...................... 47 Your Bryant 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 easy to love. Easy to install: All 558J units are horizontal. No special adapter curbs are necessary. Convertible airflow design makes it easy to adjust to unexpected job- --site complications. Lighter units make easy replacement. Bryant 3- --6 ton 558J rooftops fit on existing Bryant curbs. Also, our large control box gives you room to work and room to mount Bryant accessory controls. Easy to maintain: Bryant’s easy access handles 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: Bryant rooftops have high and low pressure switches, a filter drier, and 2” filters standard. Bryant’s terminal board puts all your connections and troubleshooting points in one 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. 2 FEATURES AND BENEFITS S Up to 28% lighter than similar industry units. Lighter rooftops make easier replacement jobs. S 3- --6 ton units fit on existing Bryant small rooftop curb. 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 Field convertible airflow (3- --6 tons). Being able to convert a unit from vertical airflow to horizontal makes it easy to overcome job site complications. S Easy- --adjust, belt- --drive motor available. Bryant provides a factory solution for most points in the fan performance table. There’s no need for field- --supplied drives or motors. S Provisions for bottom or side condensate drain. S Capable of thru- --the- --base or thru- --the- --curb electrical routing. 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 Color- --coded wiring. S Large, laminated wiring and power 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- --strip” screw system guides screws into the panel and captures them tightly without stripping the screw, the panel, or the unit. S Exclusive, newly- --design indoor refrigerant header for easier maintenance and replacement. S Mechanical cooling (115_F--25_F/ 46_C--4_C) on Direct Digital Controller (DDC) (RTU- --MP controller). S Mechanical cooling (115_F--25_F/ 46_C--4_C) on Electro- --Mechanical (E/M) models, with winter start kit. S Bryant’s naturally draining heat exchanger, unlike positive pressure heat exchangers, do not need to be periodically, manually drained. This saves labor and maintenance expense. S 2” throw away filters on all units. S Refrigerant filter- --drier. S High and low pressure switches. Added reliability with high pressure switch and low pressure switch. the environmentally sound refrigerant This product has been designed and manufactured to meet Energy Star® criteria for energy efficiency.
