FEATURES AND BENEFITS (cont.)
Efficient operation
These air cooled condensing units will provide EER’s up
to 11.2 which meets both ASHRAE and Energy Star
efficiency levels.
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
2
sensors, the economizer admits
fresh outdoor air to replace stale, recirculated indoor air.
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.
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 3 /
8
-in. diameter copper tubes
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.
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.
