Your new 15 to 25 Ton Legacy Linet Bryant rooftop unit (RTU) was designed by customers for customers. With a newly
designed cabinet that integrates “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:
These new Legacy Line units are designed for dedicated factory--supplied vertical or horizontal air flow duct
configurations. No special field kits are required. Designed to fit on pre--installed curbs by another manufacturer, these
units also fit on past designed Bryant installed curbs with an adapter curb. This new cabinet design also integrates a large
control box that 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 system pressures with panels in place as compressors are strategically
located to eliminate any air bypass.
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--in (51mm)
filters standard.
Reliable:
Each unit comes with precision sized and tested scroll compressor that is internally protected from over temperature and
pressures. In addition, each refrigerant circuit is further protected with a high pressure and low pressure switch as well as
containing a liquid line filter drier. Each unit is factory tested prior to shipment to help ensure unit operation once properly
installed.
