Your Bryant rooftop unit (RTU) was designed by customers for customers. With “no--strip” screw collars, handled access
panel s, 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. C onvertible 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 affecti ng the condenser ai rflow.
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.
