The Rheem Prestige Series®High Efficiency Two-Stage RASLJEZ Condensing Unit was designed with performance in mind. These units offer comfort, energy conservation and dependability for single, multi-family and light commercial applications.

The Rheem Prestige Series

Two-Stage RASL- JEZ Condensing Units are the result of an ongoing development program for improved efficiencies. With system SEER’s ranging to 18.50, these units continue a tradition of high efficiency.

■ The Comfort Control System

™

provides on-board diagnostics and fault history for condensing units with single-phase compressors by detecting system and electrical problems without adding sensors. It can also communicate “fault codes” to enabled “L terminal” thermostats. The integrated diagnostics with Active Protection

™

prevents compressor operation when

potentially harmful conditions are detected.

■

7-Segment LED Display is exclusive only to Rheem products. The information-display quickly and accurately shows technicians the source of malfunctions.

■

Ten-year conditional unit replacement warranty.

■ Reliable Two-Stage Scroll™ Compressor for precise tempera-

ture control providing ultimate comfort.

■ Comfort Alert™ Diagnostics comes installed in each Rheem

Prestige Series model.

■ All controls are accessible by removing one service panel.

Removable top grille provides access to the condenser fan motor and condenser coil.

■ Attractive, louvered wrap-around jacket protects the coil from

yard hazards and weather extremes. Top grille is steel reinforced for extra strength. Cabinet is powder painted for allweather protection.

■ Air is discharged upward away from bushes and shrubs. The

discharge pattern of the top grille provides minimum air restriction, resulting in quiet fan operation.

■ Exclusive Combination Grille/Motor Mount secures the motor to

the underside of the discharge grille. The grille protects the motor windings and bearings from rain and snow.

■ For quiet operation and improved efficiency, the 3 ton model fea-

ture the GE

ECM two-speed motor with a 3-blade outdoor fan.

■ All models meet or exceed a 1000-hour salt spray test per ASTM

B117 Standard Practice for Operating Salt Spray Testing Apparatus.

■ On-demand dehumidification terminal, when matched with a

Prestige Series Air Handler or premium ECM Gas Furnace products, adjusts airflow to help control humidity for unsurpassed comfort in the cooling mode.

The Rheem exclusive 7-Segment LED Display easily shows system operating status codes and diagnostic codes.

■

A Sealed Switch replaces the standard

contactor and features optical control and latching mechanism. The sealed

switch prevents infiltration of insects and dust. A minimal switching arc, by the optical control, offers greater reliability. The latching mechanism consumes less power while reducing chatter.

■

The Status Indication and System Diagnostics feature thermostat communication capability, built-in diagnostics, high & low voltage monitoring and high & low pressure switch monitoring. The thermostat communication capability alerts the

homeowner to any necessary service requirements. Faster, more accurate service is provided by the built-in diagnostics, by providing the HVAC professional with dependable information. With the high and low voltage monitoring feature, the control provides alerts for out-of-range conditions. In addition, high and low pressure-switch monitoring prevents the system from operating outside of its normal parameters.

■

The fault recall feature will allow for the last six fault-codes to be displayed, and will retain these codes even if power failure occurs.

■

Built-in short-cycle protection allows the compressor to restart easily without oil removal.

■

A 30-second minimum run-time for every compressor call allows the oil to return to the compressor.

■

Active Protection monitors the system to prevent nuisance lockouts and prevents compressor operation when potentially harmful conditions are detected.

■

The compressor and fan are controlled independently, which reduces the starting load and light dimming.

■

A manual push-button is offered to operate the compressor and fan for 5 seconds to allow for an operation check.

■

In order to save time and money, replacement automotive fuses can be utilized instead of replacing the entire control board.

STANDARD FEATURES

RASL- JEZ Condensing Units

1. Scroll compressor is hermetically sealed and incorporates internal high temperature motor overload protection, and durable insulation on the motor windings. It is externally mounted on rubber grommets to reduce vibration and noise.

2. Compressors have an internal pressure relief assembly to protect against excessive pressure differential.

3. All refrigerant connections are on the exterior of the unit, located close to the ground for neat appearing installations.

4. Cabinet is constructed of powder painted galvanized steel. The full wrap-around louvered grille protects the coil from damage.

5. Sound Blanket-enhanced compressor sound blanket is standard.

6. Copper tube—aluminum fin coils are used on all models.

7. The control box is located in the top corner of the cabinet

providing for easy access through a service panel.

8. Service valves are standard on all models.

9. Field connections for power and control wiring are kept

separate.

10. Every unit is factory charged and run-tested.

11. Separate compressor compartment for easy service access.

12. Drawn, painted base pan for extra corrosion resistance and

sound reduction.

13. The RASL- JEZ has a 10-year limited parts warranty, plus a 10-year conditional unit replacement warranty.

14. Hard Start Kits—Standard on all JEZ models.

15. Control Box Cover.

16. The RASL- JEZ is shipped with a liquid line filter drier, and

also features factory-installed low and high pressure controls.

FEATURES & BENEFITS OF THE COMFORT CONTROL SYSTEM

™

2-STAGE SCROLL ULTRA TECH

™

COMPRESSOR

The 2-Stage Scroll UltraTech™compressor is the key to efficiency for this Rheem model. It’s the latest in high-efficiency compressor technology. The advanced scroll compressor offers low noise and vibration characteristics and features tolerance to liquid refrigerant and system contamination. The Scroll UltraTech

™

also has low start torque, eliminating start problems in the field. And its unique design enables the RASL- JEZ condensing unit to perform efficiently, quietly and reliably.

All controls and compressor

are accessible for servicing by

removal of the service panel.

Accessories

■

Low Ambient Control—Cycles outdoor fan to maintain adequate condensing pressures assuring liquid refrigerant flow to the coil. Allows indoor cooling with outdoor temperatures down to 0°F [–17.8°C]. (Model No. RXADA07). It is recommended that this control be installed in units to be operated at outdoor ambient temperatures under 70°F [21°C].

■

Thermostats

■

Compressor Crankcase Heater (Model No. 44-1740244CCH) Add to minimize refrigeration migration and to help eliminate any startup noise or bearing “wash out”.
