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

refrigerant 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.

Perfect Humidityt Technology featuring Evolutionr control

and Variable--Speed Blower motor and two--stages of cooling

and heating provide greater comfort, humidity control, and energy

efficiency.

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.

Variable--Speed Blower motors provide better comfort and

energy efficiency. Economical constant fan for less than $50 a year,

which provides improved indoor air quality and more even

temperatures from room to room; and reduced indoor noise due to

lower air velocity. In addition, you’ll realize improved installation

flexibility with 3 different airflow choices for best overall comfort.

Easy installation

Factory--assembled package is a compact, fully self--contained,

combination gas heating/electric cooling 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. Units are lightweight and install

easily on a rooftop or at ground level. The high tech composite unit

base eliminates rust problems associated with ground level

applications.

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 with SEERs (Seasonal Energy Efficiency

Ratio) of up to 15.5 and AFUE (Annual Fuel Utilization

Efficiency) ratings as high at 80.1%.

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.

Dedicated Low NOx units 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 or any other location where a Low

NOx rule exists.

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. Vibration isolation provides quiet operation.

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 409

stainless 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 577D----A models.
