580J
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 Legacy Liner units are field--convertible to horizontal air flow which makes it easy to adjust to unexpecte d job site
complications. Lighter units make easy replacement. Bryant 3--15 ton 580J 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).
Easy to use:
The newly designed, central 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.

FACTORY OPTIONS AND/OR ACCESSORIES
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
provide even more savings by coupling the ventilation air
to only that amount required.
Economizers are available, installed and tested by the
factory, with eit her enthalpy or dry--bulb temperature
inputs. There are also models for electromechanical as
well as direct digital controllers. Additional sensors are
available as accessories to optimize the economizers.
Economizers include gravity controlled, barometric relief
which equalizes building pressure and ambient air

Smoke Detectors
Trust the experts. Smoke detectors ma ke your application
safer and your job easier. Bryant smoke det ectors
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)
Reduce service and/or installation costs by including a
convenience outlet in your specification. Bryant will
install this service feature at our factory. Provides a
convenient, 15 amp, 115v GFCI receptacle with “Wet in
Use” cover. The “powered” option allows the installer to
power the outlet from the line side of the disconnect or
load side as required by code. The “un--powered” option is
to be powered from a separate 115/120v power source.
Power Exhaust with Barometric Relief
Superior internal building pressure control. This field
installed accessory may eliminate the need for costly,
external pressure control fans.
RTU Open, Multi --Protocol Controller
Connect the rooftop to an existing BAS without needing
complicated translators or adapter modules using the RTU
Open controller. This new controller speaks the 4 most
common building automation system languages (Bacnet,
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 in the event of some other failure, prevents
the compressor from restarting for 30 seconds after
stopping. Not required with RTU Open, or authorized
commercial thermostats.
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.
Optional Perfect Hum idity System
Bryant’s Perfect Humidity system is an all--inclusive
factory installed option that can be ordered with any
Legacy Line 580J--04--14 rooftop unit.
This system expands the envelope of operation of Bryant’s
Legacy Line rooftop products to provide unprecedented
flexibility to meet year round comfort conditions.
The Perfect Humidit y system has the industry’s only dual
dehumidification mode setting. The Perfect Humidity
system includes two new modes of operati on.
Non--fused Disconnect
This OSHA--compliant, factory installed, safety switch
allows a service technician to locally secure power to the
rooftop.

FACTORY OPTIONS AND/OR ACCESSORIES (cont.)
The Legacy Line 580J--04--14 rooftop coupled with the
Perfect Humidity system is capable of operating in normal
design cooling mode, subcooling mode, and hot gas reheat
mode. Normal design cooling mode is when the unit will
operate under its normal sequence of operation by c ycling
compressors to maintain comfort conditions.
Subcooling mode will operate to satisfy part load type
conditions when the space requires combined sensible and
a higher proportion of latent loa d control . Hot Gas Reheat
mode will operate when outdoor temperatures diminish
and the need for latent capacity is required for sole
humidity control . Hot Gas Reheat mode will provide
neutral air for maximum dehumidification operation.
Optional St ainless Steel Heat Exchanger
The stainless steel heat exchanger option provides the
tubular heat exchanger be made out of a minimum 20
gauge type 409 stainless steel for applications where the
mixed air to the heat exchanger is expected to drop below
45_F(7_C). Stainless steel may be specified on
applications where the presence of airborne contaminants
require its use (applications such as paper mills) or in
areas with very high outdoor humidity that may result i n
severe condensation in the heat exchanger during cooling
operation.
Flue Discharge Heat Shield
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. This device should be used as
analternativetoeconomizerfreecoolingwhen
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
operation, depending on the model.
Winter Start Kit
The winter start kit by Bryant extends the low ambient
limit of your rooftop to 25_F(--4_C). The kit bypasses the
low pressure switch, preventing nuisance tripping of the
low pressure switch. Other low ambient precautions may
still be prudent.
Propane Heating
Convert your gas heat rooftop from standard natural gas
operation to propane using this field installed kit.
High Altitude Heating
High altitudes have less oxygen, which means heat
exchangers need less fuel. The new gas orifices in this
field installed kit make the necessary adjustment for high
altitude applications. They restore the optimal fuel to air
mixture and maintain healthy combustion at altitudes
above 2000 ft (610m). Kits may not be required in all
areas.
Flue Discharge Deflector
The flue discharge deflector is a useful accessory when
flue gas recirculation is a concern. By venting the flue
discharge upwards, the deflector minimizes the chance for
a neighboring unit to intake the flue exhaust.
The flue discharge heat shield kee ps people from touching
the rooftop unit’s potentially hot flue discharge. This is
especially useful for ground level applications, where
more, untrained people could have access to the unit’s
exterior.
Alternate Motors and Drives
Some applicati ons need larger horsepower motors, some
need more airflow, and some need both. Regardless of the
case, yourBryant expert has afactory installe d
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--baseconnections,availableaseitheran
accessory or as a factory option, are necessary to ensure
proper connect ion and sea l when routing wire and piping
through the rooftop’s basepan and curb. These couplings
eliminate roof penetration and should be considered for
gas lines, main power lines, as well as control power.
Disconnect Switch Bracket
Provides a pre-- engineered and sized mounting bracket for
applications requiring a unit mounted fused disconne ct of
greater than 100 amps. Bracket assures that no damage
will occur to coils when mounting with screws and other
fasteners.
Supply Duct Cover
This supply duct cover is required when field converting
the factory standard vertical duct supply to horizontal duct
supply configuration. One required per unit. (16 size only)

In the USA the input rating for altitudes above 2000 ft (610m) must be derated by 4% for each 1000 ft (305 m) above sea
level. In Canada, the input rating must be derated by 10% for altitudes of 2000 ft (610 m) to 4500 ft (1372 m) above sea level.
1. Outdoor sound data is measure in accordance with
AHRI standard 270 --- 2008.
2. Measurements are expressed in terms of sound power.
Do not compare these values to sound pressure values
because sound pressure depends on specific environmental factors which normally do not match individual
applications. Sound power values are independent of
the environment and therefore more accurate.
3. A --- weighted sound ratings filter out very high and very
low frequencies, to better approximate the response of
