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 over 100,000 systems proving
highly reliable, environmentally sound performance.
Perfect Humidity™ Technology featuring Variable Speed
Blower motors provides better comfort and energy efficiency.
You can expect up to 30 times better dehumidification; economi-
cal 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,
heat pump unit that is pre-wired, pre-piped, and pre-charged for
minimum installation expense. 604B units are available in a va-
riety of standard capacity ranges with voltage options to meet
residential and light commercial requirements. Units install eas-
ily on a rooftop or at ground-level.
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. Vibration isolation pro-
vides quiet operation. Compressors have internal high-pressure
and overcurrent protection.
Convertible duct configuration Unit is designed for easy use
in either downflow or horizontal applications. Each unit is easily
converted from horizontal to downflow and include horizontal
duct covers.
Direct-drive variable speed blower motor is standard on all
604B models.
Direct-drive, PSC condenser-fan motors are designed to help
reduce energy consumption and provide for cooling operation
down to 55°F outdoor temperature. Motormaster® II low ambient
kit is available as a field-installed accessory.
Corporate thermostats designed to work as a system with
Bryant’s small packaged product.
Refrigerant system is designed to provide dependability. Liquid
refrigerant filter driers are used to promote clean, unrestricted
operation. Each unit leaves the factory with a full Puron® refrig-
erant charge. Refrigerant service connections make checking
operating pressures easier.
Indoor and Outdoor coils are computer-designed for optimum
heat transfer and cooling 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. Copper fin coils and pre-coat-
ed fin coils are available from the factory by special order. These
coils are recommended in applications where aluminum fins are
likely to be damaged due to corrosion. They are ideal for sea-
coast applications.
Thermostatic Expansion Valve — A hard shutoff, balance port
TXV maintains a constant superheat at the evaporator exit (cool-
ing cycle) resulting in higher overall system efficiency.
High and Low Pressure Switches give added safety and reli-
ability to the compressor.
Low sound ratings ensure a quiet indoor and outdoor environ-
ment with sound ratings as low as 72 dB.
(See page 3.)
Easy to service cabinets provide easy single-panel accessi-
bility to serviceable components during maintenance and in-
stallation. The basepan with integrated drain pan provides
easy ground level installation with or without a mounting pad.
