Filter track tilts out for filter removal and replacement. All filters are the same size in each unit Installation ease All Legacy™ Line units are field- convertible to horizontal airflow, which makes it easy to adjust to unexpected job-
site complications. Lighter units make for easy replace. Simple, fast plug-in connec- tions to the standard integrated unit con- trol board (UCB). Clearly labeled connections points to reduce installation time. Also, a large control box provides room to work and room to mount Bryant accessory controls. Easy to maintain With the new Vane Axial fan system and direct drive ECM motor, there is no longer a need to adjust belts or pulleys as in past designs. This frees up maintenance and installation time. Easy access handles by Bryant provide quick and easy access to all normally ser- viced components. Our “no-strip” screw system has superior holding power and guides screws into position while prevent- ing the screw from stripping the unit’s metal. Sloped, corrosion resistant composite drain pan sheds water; and won’t rust. Easy to use The newly re-designed Unit Control Board by Bryant puts all connections and troubleshooting points in one convenient place. Most low voltage connections are made to the same board and make it easy to access it. Setting up the fan is simple by an intuitive switch and rotary dial arrangement. Bryant rooftops have high and low pressure switches, a filter drier, and 2-in. filters standard.
