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, easy to use, and easy to love.
Easy to install:
All 558J units are horizontal. No special adapter curbs are necessary. Convertible airflow design makes i t easy to adjust to
unexpected job--site complications. Lighter units make easy replacement. Bryant 3--6 ton 558J rooftops fit on existing
Bryant curbs. Also, our large control box gives you room to work and room to mount Bryant accessory controls.
Easy to maintain:
Bryant’s easy access handles 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 readings without affecting the condenser airflow.
Easy to use:
Bryant rooftops have high and low pressure switches, a filter drier, and 2” filters standard. Bryant’s terminal board puts all
your connections and troubleshooting points in one 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.

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 coupled 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. T here are also models for electromechanical as
well as direct digital controllers. Additional sensors are
available as accessories to optimize the economizers.

Smoke Detectors
Trust the experts. Smoke detectors make your application
safer and your job easier. Bryant’s 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, safety switch
allows a service technician to locally secure power to the
rooftop.
Barometric Relief
Gravity controlled, barometric relief equalizes building
pressure and ambient air pressures. This can be a cast
effective solution to prevent building pressurization.
Power Exhaust with Barometric Relief.
Superiorinternalbuildingpressurecontrol.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 needing
complicated translators or adapter modules using the
RTU--MP 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 PC, 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
conjunction with a compatible unit controller/thermostat,
the switches will activate an alarm to warn the appropriate
personnel.
Motorized 2--Position Damper
Bryant’s new, 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 t he rooftop stops, stopping
unwanted infiltration.
Manual OA Damper
Manual outdoor air dampers are an economical way to
bring in ventilation air.
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
an alternative to economizer free 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
operation, depending on the model.
Winter Start Kit
Bryant’s winter start kit extends the low ambient limit of
your rooftop to 25_F(--9_C). The kit bypasses the low
pressure switch, preventing nui sance tripping of the low
pressure switch. Other low ambient precautions may still
be prudent.
UV--C Lights
Bryant’s commercial rooftop ultra--violet germicidal
lamps are designed to kill odor causing mold and fungus
that may develop in the cool and damp evaporator section
of an HVAC unit. The high output, low tempe rature
germicidal lamps are installed in the evaporator section of
the HVAC unit, and shine dire ctly on the evaporator coil
6
and condensate pan. The short wave length ultra--violet
band light inhibits and kills mold, fungus, and microbial
growth.
Alternate Motors and Drives
Some applications need larger horsepower motors, some
need more airflow, and some need both. Regardless of the
case, Bryant 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--baseconnections, availableas 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. These couplings
eliminate roof penetration a nd should be considered for
gas lines, main power lines, as well as control power.
Electric Heaters
Bryant offers a full--line of accessory heaters. The heaters
are very easy to use and install.
