Your Bryant Packaged Heat Pump rooftop unit (RTU) was designed by custome rs for customers. Wi th 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 Legacy Linet units are field-- convertible to horizontal air flow; no special adapter curbs or kits are necessa ry.
Convertible airflow design makes it easy to adjust to unexpected job--site complications. Lighter units make easy
replacement. Bryant 3 --8.5 ton 548J 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 readi ngs without affecting the condenser a irflow.
Easy to use:
The newly de signed, master terminal board by Bryant puts al l your connec tions and troubleshooting poi nts in one
convenient place, standard. Most low voltage connections are made to the same board and make i t 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.

FACTORY OPTIONS AND/OR ACCESSORIES (cont.)
Economizer (dry--bulb or enthalpy)
Economizers save money. They bring in fresh, outside air
for ventilation; and provide cool, outside air to cool your
building. This is the preferred method of low--ambient
cooling. When c oupled to CO
2
sensors, Economizers ca n
provide even more savings by coupling the ventilation air
to only that amount required.
Economizers are available, installed and tested by the
factory, with either enthalpy or dry--bulb temperature
inputs. There are also models for electrome chanical as
well as direct digital controllers. Additional sensors are
available a s accessories to optimize the economizers.
Economizers include gravity controlled, barometric relief
equalizes building pressure and ambient air pressures.
This can be a cast effective solution to prevent building
pressurization.
CO
2
Sensor
Improves productivity and saves money by working with
the economizer to i ntake only the correct amount of
outside air for ventilation. As occupants fill your building,
the CO
2
sensor detects their presence through increasing
CO
2
leve ls, and opens the economizer appropriately.
When the occupants leave, the CO
2
levels decrease, and
the sensor appropriately closes the economizer. This
intelligent control of the ventilation air, called Demand
Control Ventilation (DCV) reduces the overall load on the
rooftop, saving money.
Smoke Detectors
Trust the experts. Smoke det ectors make your application
safer and your job easier. Bryant smoke detectors
immediately shut down the rooftop unit when smoke is
detected. They are available, installed by the factory, for
supply air, return air, or both.
Louvered Hail Guards
Sleek, louvered panels protect the condenser coil from
hail damage, foreign objects, and incidental contact.
Convenience Outlet (powered or un--powered)
Lower service bills by including a convenience outlet in
your specification. Bryant will install this service feature
at our factory, powered. Provides a convenient, 15 amp,
115V GFCI receptacle.
Non--fused Disconnect
This OSHA --compliant, factory--installed, sa fety switch
allows a service technician to locally secure power to the
rooftop.
Power Exhaust Pr essure Relief
Superior internal building pressure control. This
field-- installed accessory may eliminate the need for
costly, external pressure control fans.
RTU--MP, Multi--protocol Controller
Connect the rooftop to an existing BAS without ne eding
complicated translators or adapter modules using the
RTU--MP controller. This new controller speaks the 4
most common building automation system languages
(Bacne t, Modbus, N2, and Lonworks). Use this controller
when you have an existing BAS.
Time Guard II Control Circuit
This accessory protects your compressor by preventing
short--cycling i n the event of some other fa ilure, prevents
the compressor from restarting for 30 seconds after
stopping. Not required with RTU--MP or authorized
commercial thermostats.
Filter or Fan Status Switches
Use these differential pressure switches to detect a filter
clog or indoor fan motor failure. When used in
conjunc tion with a compatible unit controller/thermostat,
the switches will activate an alarm to warn the appropriate
personnel.
Motorized 2--Position Damper
The new Bryant 2--position, motorized outdoor air damper
admits up to 100% outside air. Using reliable, gear-- driven
technology, the 2--position damper opens to allow
ventilation air and closes when the rooftop stops, stopping
unwanted infiltration.
Manual OA Damper
Manual outdoor air dampers are an economical way to
bring in ventilation air. The dampers are available in 25%
and 50% versions.

FACTORY OPTIONS AND/OR ACCESSORIES (cont.)
Motormaster Head Pressure Controller
The Motormaster motor controller is a low ambient, head
pressure controller kit that is designed to maintain the
unit’s condenser head pressure during periods of low
ambient cooling operation. Thi s device should be used as
an alternative to economizer fre e cooling not when
economizer usage is either not appropriate or desired. The
Motormaster will either cycle the outdoor--fan motors or
operate them at reduced speed to maintain the unit
operat ion, depending on the model.
Alternate Motors and Drives
Some appli cations need larger horsepower motors, some
need more airflow, and some need both. Regardless of the
case, your Bryant expert has a factory installed
combination to meet your application. A wide selection of
motors and pulleys (drives) are available, factory
installed, to handle nearly any application.
Thru--the--Base Connections
Thru--the--base connections, available as either an
accessory or as a factory option, are necessary to ensure
proper connection and seal when routing wire and piping
through the rooftop’s basepan and curb. The se couplings
eliminate roof penetration and should be considered for
gas lines, main power lines, as well as control power.
Electric Heaters
Bryant offers a full--line of field--installed accessory
heaters. The heaters are very easy to use, install and are
all pre --engineered and certified.
