Puron 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. Puron
refrigerant is in service in millions of systems proving highly
reliable, environmentally sound performance.
Easy Installation
Factory--assembled package is a compact, fully self--contained,
combination gas heating/electric cooling unit that is prewired,
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
lightweight and install easily on a rooftop or at ground level. The
high tech composite base eliminates rust problems associated with
ground level applications.
Innovative Unit Base Design
On the inside a high--tech composite material will not rust and
incorporates a sloped drain pan which improves drainage and helps
inhibit mold, algae and bacterial growth. On the outside metal base
rails provide added stability as well as easier handling and rigging.
Convertible duct configuration
Unit is designed for use in either downflow or horizontal
applications. Each unit is converted from horizontal to downflow
and includes two horizontal duct covers. Downflow operation is
provided in the field to allow vertical ductwork connections. The
basepan seals on the bottom openings to ensure a positive seal in
the vertical airflow mode.
Efficient operation
High--efficiency design offers SEER (Seasonal Energy Efficiency
Ratios) of 15.0 to 16.0, 12.0 to 12.5 EER, and AFUE (Annual
Fuel Utilization Efficiency) 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.
Low NOx units are designed for California installations and meet
40 ng/J NOx emissions. Can be installed in air quality management
districts with a 40 ng/J NOx emissions requirement.
Durable, dependable components
Compressors have two stages of cooling and are designed for high
efficiency. Each compressor 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 accessible in one
Turbo--tubulart heat exchangers are constructed of aluminized
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
Stainless steel heat exchanger available as factory installed option.
Multi--speed ECM Blower Motor is standard on all models.
High Efficiency 2--Speed Inducer Motor on single phase models.
Direct--drive PSC (Permanent Split Capacitor) condenser--fan
motors are designed to help reduce energy consumption and
provide for cooing operation down to 40_F (4.4_C) outdoor
temperature. Motormasterr II low ambient kit is available as a
field--installed accessory.
Thermostatic Expansion Valve -- A hard shutoff, balance port
TXV maintains a constant superheat at the evaporator exit (cooling
cycle) resulting in higher overall system efficiency.
Refrigerant system is designed to provide dependability. Liquid
filter driers are used to promote clean, unrestricted operation. Each
unit leaves the factory with a full refrigerant charge. Refrigerant
service connections make checking operating pressures easier.
High and Low Pressure Switches provide added reliability for the
Indoor and Outdoor coils are computer--designed for optimum
heat transfer and efficiency. The indoor coil is fabricated from
copper tube and aluminum fins and is located inside the unit for
protection against damage. The outdoor coil is internally mounted
on the top tier of the unit.
Low sound ratings ensure a quiet indoor and outdoor
environment with sound ratings as low as 72dBA.
Dehumidification Feature
This unit has independent fan speeds for low stage cooling and
high stage cooling. In addition, 208/230 VAC models have the
field--selectable capability to run an enhanced dehumidification
(’DHUM’) speed on high stage cooling (as low as 320CFM per
ton). Coupled with the improved dehumidification associated with
low stage cooling, the DHUM speed allows for a complete
dehumidification solution independent of cooling stage. 208/230
VAC models also have independent fan speeds for low stage gas
heating and high stage gas heating. The dehumidification control
must open the control circuit on humidity rise above the
dehumidification set point.

Easy to service cabinets provide easy 3--panel accessibility to
serviceable components during maintenance and installation. The
basepan with integrated drain pan provides easy ground level
installation with mounting pad. A nesting feature ensures a positive
basepan to roof curb seal when the unit is roof mounted. A
convenient 3/4--in. (19.05 mm) wide perimeter flange makes frame
mounting on a rooftop easy.
Standard horizontal metal duct covers with insulation come
with the unit and cover the horizontal duct openings. These can be
left in place if the units are converted to downflow.
Integrated Gas Control (IGC) board provides safe and efficient
control of heating and simplifies trouble--shooting through its
built--in diagnostic function.
Cabinets are constructed of heavyduty, phosphated, zinc--coated
prepainted steel capable of withstanding 500 hours in salt spray.
Interior surfaces of the evaporator/heat exchanger compartment are
insulated with foil--faced insulation, which keeps the conditioned
air from being affected by the outdoor ambient temperature and
provides improved indoor air quality. (Conforms to American
Society of Heating, Refrigeration and Air Conditioning Engineers
