FEATURES & BENEFITS OF THE COMFORT CONTROL SYSTEM ™ I The Rheem exclusive 7-Segment LED Display easily shows system operating status codes and diagnostic codes. I 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. I 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-ofrange conditions. In addition, high and low pressure-switch monitoring prevents the system from operating outside of its normal parameters. I 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. I Built-in short-cycle protection allows the compressor to restart easily without oil removal. I A 30-second minimum run-time for every compressor call enables the oil return to the compressor. I Active Protection monitors the system to prevent nuisance lockouts and prevents compressor operation when potentially harmful conditions are detected. I The compressor and fan are controlled independently, which reduces the starting load and light dimming. I A push-button is offered to operate the compressor and fan for 5 seconds to allow for an operation check. I In order to save time and money, replacement automotive fuses can be utilized instead of replacing the entire control board. STANDARD FEATURES RAPL- JEZ/RANL- JEZ Condensing Units 1. This unit contains a special scroll compressor that is designed specifically to operate with R-410A refrigerants and polyolester (POE) oils. The 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. 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. 3. Compressors have an internal pressure relief assembly to protect against excessive pressure differential. 4. All refrigerant connections are on the exterior of the unit, located close to the ground for neat appearing installations. 5. Cabinet is constructed of powder painted galvanized steel. The full wrap-around louvered grille protects the coil from damage. 6. Enhanced compressor sound blanket is standard. 7. Copper tube-aluminum fin coils are used on all models. 8.

Field connections for power and control wiring are kept separate. 11. Every unit is factory charged and run-tested. 12. Separate compressor compartment for easy service access. 13. Drawn, painted base pan for extra corrosion resistance and sound reduction. 14. The RAPL- JEZ and RANL- JEZ have a 10 year limited compressor warranty, plus a 5 year conditional unit replacement warranty. 15. Hard Start Kits-Standard on all JEZ models. 16. Control Box Cover. 17. Automatic reset high and low pressure controls are standard on all JEZ models. 18. Liquid line filter drier is standard on all models (shipped - not installed). SCROLL® COMPRESSOR The scroll 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 compressor also has low start torque, eliminating start problems in the field. And its unique design enables the RAPL- JEZ and RANL- JEZ condensing units to perform efficiently, quietly and dependably. All controls and compressor are accessible for servicing by removal of the service panel. 2 Rheem Manufacturing Company
