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 and easy to use.
Easy to install:
All Preferred Series
t
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 581J 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.
