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,
electric cooling unit that is pre--wired, pre--piped, and
pre--charged for minimum installation expense. 704C units are
available in a variety of standard capacity ranges with voltage
options to meet residential and light commercial requirements.
Units install easily on a rooftop or at ground level.
Durable, dependable components
Compressors 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.
Convertible duct configuration
Unit is designed for easy use in either downflow or horizontal
applications. Each unit is easily converted from horizontal to

Puron
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. 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 over 100,000 systems
proving highly reliable, environmentally sound performance.
PerfectHumidityt Technology featuring Evolutiont control
and Variable--Speed Blower motor that provides greater
comfort, humidity control, and energy efficiency.
Variable--Speed Blower motors provide better comfort and
energy efficiency. You can expect up to 30 times better
dehumidification; economical constant fan which provides
improved indoor air quality and more even temperatures from
Environmentally--Sound Refrigerant is Bryant’s
downflow and includes horizontal duct covers.
Direct--drive, variable--speed blower motor is standard on all
704C 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
low--ambient kit is available as a field --installed accessory.
Evolutiont User Interface designed to work as a system with
Bryant’s single--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
refrigerant 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--coated 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 seacoast applications.
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.
High-- and Low--Pressure Switches give added safety and
reliability to the compressor.
Low sound ratings ensure a quiet indoor and outdoor
environment with sound ratings as low as 72 dB. (See page 3.)
Easy to service cabinets provide easy single--panel accessibility
to serviceable components during maintenance and installation.
The basepan, with integrated drain pan, provides easy ground
level installation with or without a mounting pad. Convenient

handholds are provided to manipulate the unit on the job site. A
nesting feature ensures a positive basepan to roof curb seal when
the unit is roof mounted. A convenient 3/4--in. wide perimeter
flange makes frame mounting on a rooftop easy.
Louvered grille provides hail and vandalism protection for the
coil.
Downflow operation is easily provided in the field to allow
vertical ductwork connections. The basepan utilizes knockout
style seals on the bottom openings to ensure a positive seal in the
horizontal airflow mode.
Cabinets are constructed of heavy--duty, phosphated,
zinc--coated, pre--painted steel capable of withstanding 500 hrs of
salt spray. Interior surfaces of the evaporator and electric heater
compartments are insulated with cleanable semi--rigid insulation
board, 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 No. 62P.) The sloped drain pan
minimizes standing water in the drain, which is provided with an
external drain.
Standard 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.
Limited Warranty—Standard 5--year limited warranty on all
parts, 10--year limited warranty on compressor.
