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 designoffers SEER
(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.

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.
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.
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.

High and Low Pressure Switches provide added reliability for the
compressor.
Indoor and Outdoor coils are computer--designed for optimum
heat transfer and 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.
Low sound ratings ensure a quiet indoor and outdoor
environment with sound ratings as low as 75dBA.
Easy to service cabinets provide easy 3--panel accessibility to
serviceable components during maintenance and installation. The
basepan with integrated drain pan provides easy ground level
installation with a mounting pad. A nesting feature ensures a
positive basepan to roof curb seal when the unit is roof mounted. A
convenient 3/4--in. (19.05 mm) wide perimeter flange makes frame
mounting on a rooftop easy.
Horizontal metal duct covers are standard 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.
Integrated Gas Control (IGC) board provides safe and efficient
control of heating and simplifies trouble--shooting through its
built--in diagnostic function.
Cabinets are constructed of heavyduty, phosphated, zinc--coated
prepainted steel capable of withstanding 500 hours in salt spray.
Interior surfaces of the evaporator/heat exchanger compartment 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 andAir
Conditioning Engineers 62.2.) The sloped drain pan minimizes
standing water in the drain. An external drain is provided.

NOTES:
1. Roof curb must be set up for unit being installed.
2. Seal strip must be applied, as required, to unit being installed.
3. Roof curb is made of 16-- gauge steel.
4. Attach ductwork to curb (flanges of duct rest on curb).
2. Select uni t based on required cooling capacity.
Enter Net Cooling Capacities table at condenser entering
temperature of 95°F(35°C). Unit 036 at 1200 CFM and 67°F
(19°C) ewb (entering wet bulb) will provide a total capacity of
34,400 Btuh and a SHC of 25,900 Btuh. Calculate SHC correction,
if required, using Note 4 under Cooling Capacities tables.
574D-- --A
3. Select heating capacity of unit to provide design
condition requirement.
In the Heating Capacities and Efficiencies table, note that the unit
036090 will provide 72,000 Btuh with an input of 90,000 Btuh.
4. Determine fan speed and power requirements at
design conditions.
Before entering the air delivery tables, calculate the total static
pressure required. From the given example, the Wet Coil Pressure
Drop Table, and the Filter Pressure Drop Table:
External Static Pressure0.30 in. W.C.
Filter0.13 in. W.C.
Wet Coil Pressure Drop0.10 in. W
Total Static Pressure0.53 in. W.C
Enter the table for Dry Coil Air Delivery—Horizontal and
Downflow Discharge. At .53 in. W.C. ESP, the closest speed to
1200 CFM is Med--High (orange wire), which delivers 1316 CFM
at .6 in ESP.

5. Select unit that corresponds to power source
available.
The Electrical Data Table shows that the unit is designed to operate
at 230--1--60.
