Bryant’s 556A with Puron
unmatched by any other family of equipment. The 556A is an
air conditioning system utilizing Bryant’s Puron refrigerant.
The environmentally sound refrigerant allows you to make a
responsible decision in the protection of the earth’s ozone
layer. Bryant’s 556A system with Puron refrigerant meet the
Energy Star® guidelines for energy efficiency.
®
Puron
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 impor tant 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 thousands of systems
proving highly reliable, environmentally sound performance.
Bryant’s Evolution™ Controls
controls, when installed with Bryant’s Perfect Humidity™
variable-speed furnaces or fan coils, provide the homeowner
with:
–unparalleled control of temperature, humidity, indoor air
quality, and zoning
–unprecedented ease of use
–simple operation through on-screen, text-based service
reminders
Optional remote access through telephone or Internet is also
available when combined with a remote connectivity kit.

556A
Sizes 024 thru 060
Heavy Duty Inlet Grille
made of a coated steel wire grid with vertical 3/8 in. spacing,
is designed to help protect the coil from inclement weather,
vandalism, and incidental damage. It provides protection
while not restricting airflow and maintaining ease of coil
inspection and cleaning.
High Efficiency Performance
bination of features including Bryant’s Puron refrigerant,
scroll compressor, and adv anced heat transfer surfaces. Efficiency ratings are 14 SEER (Seasonal Energy Efficiency
Ratio) with enhanced ratings of up to 15.75 SEER. Sophisticated heat transfer surfaces utilized in Bryant’s 556A design
allow heat to easily be transferred to the outdoor air and
require less energy. The scroll compressor found in the 556A
design performs quietly and adds to the overall efficiency of
the system. The efficiency levels provided by the 556A provide end users with lower costs of operation than traditional
air conditioning systems.
Assured Future Service
sound refrigerant, Puron, 556A models will remain serviceable well into the future. The Clean Air Act of 1990 has
placed a cap on production of most other refrigerants which
has scheduled reductions beginning in 2004. The resulting
cap in production ultimately results in a complete ban on
many other refrigerants in new equipment by the year 2010.
These changes, required by federal law, mean the supply of
other refrigerants may be limited in the near future making
Puron the correct choice when considering long term serviceability.
Highly Reliable Performance
superior design of the system and componentry. The reliability of the 556A model has been proven to provide the
lowest incidence of warranty service of any product in the
Bryant family. Long term reliability is assured through the
use of both high and low pressure switches which will not
allow the system to operate in the event of a significant
change in operating pressure. In doing this, the system is
protected from damage if an unusual condition arises.
Finally, Bryant includes a special liquid line filter drier
designed to trap moisture and contaminants which could
otherwise shorten the life of the system.
Bryant’s AeroQuiet System
sound is the result of special attention to the air moving
through the outdoor unit, and a specially designed sound
enclosure surrounding the compressor to eliminate sound
transmission to the rest of the systems.

specially designs both the outdoor product and indoor coil products to operate with assured reliability and performance. A wide
range of indoor coil options are listed in the ratings section of
this publication.
Special Protective Devices
and internal protection in the compressor including temperature
and current sensing overloads prevent operation under potentially damaging circumstances. A special liquid line filter drier
designed to trap nearly 4 times the volume of contaminants of

1.
Ball-Bearing Fan Motor
A fan motor with ball bearings which permits speed reduction while maintaining bearing lubrication.
Usage Guideline:
2.
Coastal Filter
A mesh screen inserted under the top cover and inside the base pan to protect the condenser coil from salt damage without restricting airflow.
3.
Compressor Start Assist – Capacitor and Relay
Start capacitor and relay gives a "hard" boost to compressor motor at each start up.
Usage Guideline:
4.
Compressor Start Assist — PTC Type
Solid state electrical device which gives a "soft" boost to the reciprocating compressor at each start-up.

ACCESSORY DESCRIPTION AND USAGE (continued)
5.
Crankcase Heater
An electric resistance heater which mounts to the base of the compressor to keep the lubricant warm during off cycles. Improves compressor lubrication
on restart and minimizes the chance of liquid slugging.
Usage Guideline:
6.
Evaporator Freeze Thermostat
An SPST temperature-actuated switch that stops unit operation when evaporator reaches freeze-up conditions.
Usage Guideline:
7.
Liquid-Line Solenoid Valve (LLS)
This device serves two purposes. It is an electrically operated shutoff valve which stops and starts refrigerant liquid flow in response to compressor operation. It maintains a column of refrigerant liquid ready for action at next compressor operation cycle. It also provides system protection against off-cycle
refrigerant migration.
Note:
When LLS is used with reciprocating compressors, Compressor Start Assist — Capacitor and Relay is required.
Usage Guideline:
8.
MotorMaster®—Low-Ambient Controller
A fan-speed control device activated by a temperature sensor, designed to control condenser fan motor speed in response to the saturated, condensing
temperature during operation in cooling mode only. For outdoor temperatures down to –20°F (–28.9°C), it maintains condensing temperature at 100°F ±
10°F (37.8°C ± –12°C).
Usage Guideline:
9.
Outdoor Air Temperature Sensor
Designed for use with Bryant Thermostats listed in this publication. This device enables the thermostat to display the outdoor temperature. This device also
is required to enable special thermostat features such as auxiliary heat lock out.
Usage Guideline:
10.
Sound Hood
Wraparound sound reducing cover for the compressor. Reduces the sound level by about 2 dBA.
Usage Guideline:
11.
Support Feet
Four stick-on plastic feet that raise the unit 4 in. above the mounting pad. This allows sand, dirt, and other debris to be flushed from the unit base, minimizing
corrosion.
Usage Guideline:
12.
Thermostatic Expansion Valve (TXV)
A modulating flow-control valve which meters refrigerant liquid flow rate into the evaporator in response to the superheat of the refrigerant gas leaving the
evaporator. Kit includes valve, adapter tubes, and external equalizer tube. Hard shut off types are available.
Note:
When using a hard shut off TXV with single phase reciprocating compressors, a Compressor Start Assist — Capacitor and Relay is required.
Usage Guideline:
13.
Time-Delay Relay
An SPST delay relay which briefly continues operation of indoor blower motor to provide additional cooling after the compressor cycles off.
Note:
Most indoor unit controls include this feature. For those that do not, use the guideline below.
Usage Guideline:
Required in low ambient applications.
Required in long line applications.
Suggested in all commercial applications.
Required when low ambient kit has been added.
Required in air conditioner long line applications with a piston indoor metering device to prevent off cycle refrigerant migration. A hard shut
off TXV can be used instead of an LLS in single flow air conditioner applications. See Long Line Application Guideline.
A MotorMaster®—Low-Ambient Controller or Low-Ambient Pressure Switch must be used when cooling operation is used at outdoor temperatures below 55°F (12.8°C).
Suggested for all commercial applications.
Suggested for all Bryant thermostats listed in this publication.
Suggested when unit is installed closer than 15 ft to quiet areas—bedrooms, etc.
Suggested when unit is installed between two houses less than 10 ft apart.
Suggested in the following applications:

Rooftop installations.
For improved sound ratings.
Required to achieve ARI ratings in certain equipment combinations. Refer to combination ratings.
Hard shut off TXV or LLS required in air conditioner long line applications
Required for use on all zoning systems.
For improved efficiency ratings for certain combinations of indoor and outdoor units. Refer to ARI Unitary Directory.
