FEATURES / BENEFITS
These dependable outdoor air cooled condensing units
match Bryant’s indoor-air handlers to meet a wide
selection of cooling solutions.
Constructed for long life
The 569J single circuit and 569J dual circuit, scroll
compressor models are designed and built to last. The
high efficient designed outdoor coil construction allows
for a more efficient design in a smaller cabinet size that
utilizes an overall reduction in refrigerant charge. Where
conditions require, special coil coating coil protection
option is available. Cabinets are constructed of prepainted
galvanized steel, delivering unparalleled protection from
the environment. Inside and outside surfaces are protected
to ensure long life, good looks, and reliable operation.
Safety controls are used for enhanced system protection
and reliability.
Each unit utilizes the Comfort Alert diagnostic and
troubleshoot control system. This protects the units
operation and provides valuable diagnostic information
when required.
FEATURES AND BENEFITS (cont.)
Factory-installed options (FIOPs)
Certified and pre--engineered factory-installed options
(FIOPs) allow units to be installed in less time, thereby
reducing installed cost. FIOPs include:
S low ambient controls which provide cooling operation
down to --20_F(--29_C) ambient temperatures
S non-fused disconnect
S 115-v GFI (ground fault interrupter) convenience outlet,
powered and non--powered available
S special coil coating coil protection
S louvered hail guard
Efficient operation
These air cooled condensing units will provide EER’s up
569J
to 11.5 which meets ASHRAE 90.1 efficiency levels. The
569J dual compressor models provide two (2) stages of
cooling for remarkable partial load performance.
This high efficiency will help reduce overall operating
cost and energy consumption.
Controls for performance dependability
The 569J condensing units offer operating controls and
components designed for performance dependability. The
high efficiency hermetic scroll compressor is engineered
for long life and durability. The compressors include
vibration isolation for quiet operation. The high-pressure
switch protects the entire refrigeration system from
abnormally high operating pressures. A low-pressure
switch protects the system from loss of charge. These
units also include anti-short-cycling protection, which
helps to protect the units against compressor failure.
All units include a crankcase heater to eliminate liquid
slugging at start-up. Each unit comes standard with the
Comfort Alertt control system. This provides:
S System Go LED indicator
S Fault LED indicator
S Compressor fault LED indicator
S Phase loss protection
S Phase reversal protection
S Safety pressure indicator
S Anti--short cycle protection
The latest safety standards for 569J* units are assured
through UL, Canada approvals.
Innovative Bryant 524J packaged air
handlers are custom matched to 569J*condensing units
Information on matching 524J DX packaged air handler
follows for convenience. See separate product data for
more details. The 524J Series has excellent fan
performance, efficient direct-expansion (DX) coils, a
unique combination of indoor-air quality features, and is
easy to install. Its versatility and state-of-the-art features
help to ensure economical performance of the split system
both now and in the future.
Indoor--air quality (IAQ) features
The unique combination of IAQ features in the 524J
Series air handlers help to ensure that only clean, fresh,
conditioned air is delivered to the occupied space.
Direct-expansion (DX) 4 row cooling coils prevent the
build-up of humidity in the room, even during part-load
conditions.
Standard 2-in. (51mm) disposable filters remove dust and
airborne particles from the occupied space for cleaner air.
The pitched, non-corroding drain pan can be adjusted for
a right-hand or left-hand connection to suit many
applications and provide positive drainage and prevent
standing condensate.
The accessory economizer can provide ventilation air to
improve indoor-air quality by using demand control
ventilation. When used in conjunction with Bryant
Comfort System and CO

Economy
The 524J Series packaged air handlers provide reduced
installation expense and energy-efficient performance.
Quick installation is ensured by the multipoise design.
Units can be installed in either the horizontal or vertical
configuration without modifications. Fan motors and
contactors are pre--wired and thermostatic expansion
valves (TXVs) are factory-installed on all 524J models.
High efficiency, precision-balanced fans minimize air
turbulence, surging, and unbalanced operation, cutting
operation expenses.
The economizer accessory precisely controls the blend of
outdoor air and room air to achieve comfort levels. When
the outside air enthalpy is suitable, outside air dampers
can fully open to provide “free” cooling without
energizing mechanical cooling.
Rugged dependability
The 524J series units are made to last. The die-formed
galvanized steel panels ensure structural integrity under
all operating conditions. Galvanized steel fan housings are
securely mounted to a die-formed galvanized steel fan
deck.
Rugged pillow-block bearings (524J14) are securely
fastened to the solid steel fan shaft with split collets and
clamp locking devices. Smaller unit sizes have spider-type
bearings.

FEATURES AND BENEFITS (cont.)
Coil flexibility
Model 524J direct- expansion coils have galvanized steel
casings; inlet and outlet connections are on the same end.
The coils are designed for use with Puron (R--410A)
refrigerant and have
mechanically bonded to aluminum sine-wave fins. The
coils include matched, factory-installed thermostatic
expansion valves (TXVs) with matching distributor
nozzles and offers a removable power element and
extended connections.

/8-in. diameter copper tubes
Easier installation and service
The multipoise design and component layout ensures
quick unit installation and operation. Units can be
converted from horizontal to vertical operation by simply
repositioning the unit. Drain pan connections are
duplicated on both sides of the unit. The filters, motor,
drive, TXVs, and coil connections are all easily accessed
by removing a single side panel.

E-coated aluminum-fin coils have a flexible and durable
epoxy coating uniformly applied to all coil surfaces.
Unlike brittle phenolic dip and bake coatings, E-coating
provides superior protection with unmatched flexibility,
edge coverage, metal adhesion, thermal performance, and
most importantly, corrosion resistance.
E-coated coils provide this protection since all coil
surfaces are completely encapsulated from environmental
contamination. This coating is especially suitable in
industrial environments.
Pre--coated coils (RTPF coils only) provide protection in
mild coastal environments.

locally at the condensing unit. This switch also includes a
power lockout capability to protect the service person.
This lockout switch saves the service person time and
effort because there is no need to access a distant
disconnect switch while servicing the unit.

Two-row hot water coils have5/8-in. diameter copper
tubes mechanically bonded to aluminum plate fins. Coils
have non-ferrous headers.
One-row steam coil has 1-in. OD copper tube and
aluminum fins. The Inner Distributing Tube (IDT) design
provides uniform temperatures across the coil face. The
IDT steam coils are especially suited to applications
where sub-freezing air enters the unit.
Electric resistance heat coils have an open-wire design
and are mounted in a rigid frame. Safety cutouts for high
temperature conditions are standard.
Economizer (enthalpy controlled) provides ventilation
air and provides “free” cooling if the outside ambient
temperature and humidity are suitable. The economizer
can also be used in conjunction with Bryant Comfort
System thermostats and CO
air quality requirements. The economizer can be used in
both vertical and horizontal positions.
Discharge plenum directs the air discharge into the
occupied space; integral horizontal and vertical louvers
enable redirection of airflow. This accessory is available
unpainted or painted.
Return-air grille provides a protective barrier over the
return-air opening and gives a finished appearance to units
installed in the occupied space. This accessory is available

UV-C germicidal lamps kill mold and fungus that may
grow on evaporator coil and condensate pan surfaces. The
use of UV-C germicidal lamps eliminates the foul odors
that result from mold and fungus growth. These lamps
also provide a self-cleaning function for the evaporator
coil and drain pan. Contact application engineer for info.

SELECTION PROCEDURE
Combination ratings for 569J* units matched with 524J
Series air handlers are in this book. If unit is used with an
air handler, use the Bryant Electronic Catalog AHU
(Air-Handling Unit) selection program to obtain combined
ratings.
I. Determine cooling load, evaporator-air
temperature, and quantity.
Given:
Total Cooling Capacity
Required (TC) 121,000 Btuh...................
Sensible Heat Capacity
Required (SHC) 95,000 Btuh...................
Compressor Type Scroll.........................
Temperature Air Entering
Condenser (Edb) 95_F.........................
Temperature Air Entering
Evaporator (db/wb) 80_F db, 67_Fwb............
Evaporator Air Quantity 4,000 cfm.................
External Static Pressure 0.4 in. wg.................
Length of Interconnecting
Refrigerant Piping 25 ft (Linear).................
Power Supply (V-Ph-Hz) 208/230-3-60.............
II. Select condensing unit air-handler combination.
For this example, select a 569J*12 matched with a
524J012 coil. This 569J*12/524J12 condensing unit
air-handler combination provides 122,000 Btuh of total
cooling capacity and 97,200 Btuh of sensible capacity at
the given conditions. If other temperatures or airflow
values are required, interpolate the values from the
combination ratings.
III. Determine sizes of liquid and suction lines.
Enter Refrigerant Piping Sizes table. The sizes shown
are based on an equivalent length of pipe. This
equivalent length is equal to the linear length of pipe
indicated at the top of each sizing column, plus a 50%
allowance for fitting losses. (For a more accurate
determination of actual equivalent length in place of
using the estimated 50% value, refer to Bryant System
Design Manual.) For this example, note in the linear
length column that the proper pipe size is

/2in. for the
IV. Determine fan rpm and bhp (brake horsepower).
Refer to the 524J Air Handler Catalog -- Fan
Performance table. Enter the Air Handler Fan
Performance table at 524J12 at 4000 cfm and move to
the External Static Pressure (ESP) column. Note that the
conditions require 803 rpm at 1.77 bhp.
V. Determine motor and drive.
Enter the Fan Motor Data tables and find the standard
motor for 524J12 unit rated at 2.4 Hp. Since the bhp
required is 1.77, a standard motor satisfies the
requirement and should be used.
Next, find the type of drive that satisfies the 803 rpm
requirement in the Drive Data tables. For the 524J012
unit, the Standard Drive table shows an rpm range of
666-863. Since the rpm required is 803, the standard
drive satisfies the requirement and should be used.
CONTROLS
Operating sequences
When the wall thermostat calls for cooling, terminals G
and Y1 are energized. As a result, the indoor fan contactor
(IFC) and the compressor contactor (C1) are energized,
causing the indoor fan motor (IFM), compressor #1, and
outdoor fans (OFM) to start. The field--supplied and
field--installed liquid line valve also opens, allowing the
system to function in Cooling mode.
If the unit has 2 stages of cooling, the wall thermostat will
additionally energize Y2. The Y2 signal will energize
compressor contactor #2 (C2), causing compressor #2 to
start.
Regardless of the number of stages, the field--supplied
liquid line valve shall opens and the outdoor fan
motors(OFM) runs continuously while unit is cooling.
When cooling demand decrease, the thermostat will
de--energize Y2. Y2 signal will de--energize compressor
contactor #2 (C2), causing compressor #2 to stop.
When cooling demand has been satisfied, the thermostat
will de--energize Y1, and G terminals. Y1 and G signal
will de--energize compressor contactor #1 (C1), causing
compressor #1 to stop. If the wall thermostat is set to
continuous (CONT), the indoor fan motor will continue
to operate. Otherwise, the indoor fan motor will stop.
The outdoor fan motors (OFM) will turn off and
field--supplied liquid line valve shall close , minimizing
the potential for refrigerant migration.
