FEATURES/BENEFITS

One-- piece heating and cooling units with low sound levels, easy

installation, low maintenance, and dependable performance.

Puron Environmentally Sound Refrigera nt 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 conditioning systems as the

traditional refrigerant R -- 22 has been. 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 can be converted from horizontal to

downflow and includeds 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 14.2 to 14.5, 12.0 EER,

and AFUE (Annual Fuel Utilization Ef ficiency) 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

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 .

Direct--drive high efficiency brushless DC blower motor is

standard on all 577C----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.

Thermostat controls

Time Guardr II anti--short cycle protection circuitry. If a

non--corporate thermostat without anti--short cycle protection is

used the Time Guard II field--installed anti-- short cycle kit is

recommended.
