Single-Package Rooftop Products with Energy-Saving Features
and Puron® refrigerant.
• Direct Spark Ignition
• Low Sound Levels
• Up to 81% AFUE
• 12 SEER
AVAILABLE OPTIONS
One-piece heating and cooling units with low sound levels, easy
installation, low maintenance, and dependable performance.
Puron® Environmentally Sound Refrigerant is Bryant’s
unique refrigerant designed to help protect the environment.
Puron is an HFC refrigerant which does not contain chlorine that
can harm the ozone layer. The most important advantage of
Puron refrigerant is that it has not been banned in future air con-
ditioning systems as the traditional refrigerant R-22 has been.
Puron refrigerant is in service in thousands of systems proving
highly reliable, environmentally sound performance.
EASY INSTALLATION —Factory-assembled package is a com-
pact, fully self-contained, combination gas heating/electric cool-
ing unit that is pre-wired, pre-piped, and pre-charged for
minimum installation expense.
These units are available in a variety of standard and optional
heating/cooling size combinations with voltage options to meet
residential and light commercial requirements. Units are light-
weight and install easily on a rooftop or at ground level. The high
tech composite basepan eliminates rust problems associated
with ground level applications.
CONVERTIBLE DUCT CONFIGURATION —Unit is designed
for easy use in either downflow or horizontal applications. Each
unit is easily converted from horizontal to downflow with addition
of two duct covers.
EFFICIENT OPERATION
High-efficiency design offers SEER (Seasonal Energy Effi-
ciency Ratios) of 12.0 and AFUE (Annual Fuel Utilization Effi-
ciency) ratings as high as 81%.
Energy-saving, direct spark ignition saves gas by operating
only when the room thermostat calls for heating. Standard units
are furnished with natural gas controls. A low-cost field-installed
kit for propane conversion is available for all units.
583B units with an “N” in the thirteenth position of model #
are dedicated Low NOx units designed for California installa-
tions. These models meet the California maximum oxides of ni-
trogen (NOx) emissions requirement of 40 nanograms/joule or
less as shipped from the factory and MUST be installed in Cali-
fornia Air Quality Management Districts where a Low NOx rule
exists.
DURABLE, DEPENDABLE COMPONENTS
Compressors are designed for high efficiency. Each compres-
sor is hermetically sealed against contamination to help promote
longer life and dependable operation. Each compressor also has
vibration isolation to provide quieter operation. All compressors
have internal high pressure and overcurrent protection.
Monoport inshot burners produce precise air-to-gas mixture,
which provides for clean and efficient combustion. The large
monoport on the inshot (or injection type) burners seldom, if
ever, requires cleaning. All gas furnace components are acces-
sible in one compartment.
Turbo-tubular™ heat exchangers are constructed of alumi-
nized steel for corrosion resistance and optimum heat transfer
for improved efficiency. The tubular design permits hot gases to
make multiple passes across the path of the supply air.
In addition, dimples located on the heat exchanger walls force
the hot gases to stay in close contact with the walls, improving
heat transfer.
Direct-drive multi-speed, PSC (permanent split capacitor)
blower motor is standard on all 583B models.
Direct-drive, PSC condenser-fan motors are designed to help
reduce energy consumption and provide for cooling operation
down to 40°F outdoor temperature. Motormaster® II low ambient
kit is available as a field-installed accessory.
Corporate thermostats include the Time Guard® II anti-short
cycle protection circuitry. If an Original Equipment Manufacture
(OEM) thermostat is used the Time Guard II field installed anti-
short cycle kit must be used.
Refrigerant system is designed to provide dependability. Liquid
filter dryers are used to promote clean, unrestricted operation.
Each unit leaves the factory with a full refrigerant charge. Refrig-
erant service connections make checking operating pressures
easier.
