COMMERCIAL AIR-COOLED
CONDENSING UNITS WITH
524A AIR-HANDLING UNITS
FEATURES/BENEFITS
These dependable split systems match Bryant’s indoor-air han-
dlers and direct-expansion coils with outdoor condensing units
for a wide selection of commercial cooling solutions.
CONSTRUCTED FOR LONG LIFE — The569D(singlecir-
cuit, scroll compressor), 576C (single circuit semi-hermetic
compressor), 569F/566E (dual circuit, scroll compressor) and
566D (semi-hermetic compressor) models are designed and
built to last. The copper tube-aluminum fin outdoor coil
construction provides years of trouble-free operation. Where
conditions require them, E-coated coils and pre-coated fin coils
are also 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 con-
trols are used for enhanced system protection and reliability.
EFFICIENT OPERATION — Building owners will appreciate
the high unit EERs (Energy Efficiency Ratios) offered by these
condensing units. These units provide greater efficiency than
similar units in the marketplace, which translates into year-
round operating savings.
CONTROLS FOR PERFORMANCE DEPENDABILITY — The
condensing units offer the building owner operating controls
and components designed for performance dependability. The
highly efficient hermetic and semi-hermetic compressors are
engineered for long life and durability. The compressors
include overload protection and vibration isolation for enhance-
ment of quiet operation. The high-pressure switch protects the
entire refrigeration system from abnormally high operating
pressures. A low-pressure switch protects the system from
low-pressure conditions, including loss of charge.
The 569F120 and 566E150-240 units feature 2 scroll compres-
sors and 2 refrigerant circuits that provide continuous air
conditioning and design flexibility. These units also include
Cycle-LOC™ 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. Units with semi-hermetic compressors are also
equipped with an oil-level sight glass.
Latest safety standards are assured through UL and UL
Canada approvals.
INNOVATIVE BRYANT PACKAGED AIR HANDLERS ARE
CUSTOM MATCHED TO THE CONDENSING UNITS — The
524A Series has excellent fan performance, efficient direct-
expansion (DX) coils, a unique combination of indoor-air qual-
ity features, and easy installation. Its versatility and state-of-
the-art features help to ensure that your split system provides
economical performance now and in the future.
Indoor-Air Quality (IAQ) Features — The unique combination
of IAQ features in the 524A Series air handlers help to ensure
that only clean, fresh, conditioned air is delivered to the occu-
pied space.
Direct-expansion (DX) cooling coils prevent the build-up of
humidity in the room, even during part-load conditions. Unit
sizes of 10 tons and above feature dual-circuit coils for
improved temperature control.
Standard 2-in. disposable filters remove dust and airborne par-
ticles from the occupied space for cleaner air.
