FEATURES/BENEFITS

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. 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.

Product Data

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 can be converted from horizontal to
downflow and includes 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
(Seasonal Energy Efficiency Ratios) of up to 13.5 and AFUE
(Annual Fuel Utilization Efficiency) ratings as high as 80.4%.
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. These
A09034
models meet the California maximum oxides of nitrogen (NOx)
emissions requirement of 40 nanograms/joule or less as shipped
from the factory and MUST be installed in California Air Quality
Management Districts and wherever a Low NOx rule exists.
Durable, dependable components Compressors 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
compartment.
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
transfer.
ECM Motor is standard on all 574D- -- -A 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.
