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.

  If the compressor does not run, it could be due to an open contactor. Here's what you can do: 1. Restore power. 2. If there's a blown fuse, identify the cause, correct it, and replace the fuse with the correct size. 3. Check the control circuit breaker, and reset it if it has tripped, or replace it if it is defective. 4. Verify the thermostat settings. 5. Inspect the Time Guard II device. 6. Check for excessive compressor current draw. Reset the breaker; replace if defective. 7. Reset the lockout circuit at the thermostat or circuit breaker. 8. Check for refrigerant undercharge, obstruction of indoor airflow, or whether the compressor suction shutoff valve is fully open. 9. Check for refrigerant overcharge, obstruction of outdoor airflow, air in the system, or whether the compres...
