FEATURES AND BENEFITS (cont.)

569J

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 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

SAnti-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*condens- ing 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

aright-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 CO2 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.
