547K Legacy Line 3 to 6 Ton Packaged Heat Pump w/ Axion Fan Technology

The New Bryant Legacy™ Line packaged heat pump rooftop units (RTU) with Axion™ Fan
Technology were designed by customers for customers and integrate new technology to provide value added benefits.

New major design features include:
• Patented, industry’s first indoor fan
system using Vane Axial fan with elec-
tric commutated variable speed motor
• Reliable fixed speed scroll compres-
sor on 3-5 ton sizes and 2 stage scroll
technology on 6 ton sizes
• Upgraded unit control board with intu-
itive indoor fan adjustment
• Reliable copper tube/aluminum fin
condenser coil with 5/16-in. tubing to
help reduce refrigerant charge versus
prior designs
• New outdoor fan system with rugged —
lightweight high impact composite fan
blade

547K Legacy™ Line units up to 6 tons are specifically designed to fit on Bryant roof
curbs that were installed back to 1989, which makes replacement easy and elimi-
nates the need for curb adapters or changing utility connections.

Single-stage units deliver SEERs up to 14.3. IEERs up to 15.0 and heating HSPFs up to 8.2. All models are capable of either
vertical or horizontal airflow.

The Bryant rooftop unit (RTU) was
designed by customers for customers.
With “no-strip” screw collars, handled
access panels, and more, the unit is easy to
install, easy to maintain, and easy to use.
Precisely sized Suction Line Accumulator
to help ensure reliable operation at unit
operation conditions.
Value-added features include:
• Puron® refrigerant (R-410A)
• single point electrical connections
• RTU Open controller for BACnet1,
LonWorks2, Modbus3 and Johnson
Controls N2
• 3 to 5 ton models use fixed refrigerant
metering devices and 6 ton models use
a TXV
• scroll compressors with internal line-
break overload protection
• easy access tool-less filter door. Filter
track tilts out for filter removal and replacement. All filters are the same size in each unitInstallation 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 replacement. Simple, fast plug-in
connections to the standard integrated unit
control board (UCB). Clearly labeled con-
nections points to reduce installation time.
Also, a large control box provides room to
work and room to mount Bryant acces-
sory 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.
