The Rheem Prestige Series™ High Efficiency Two-Stage RARL/RASL-JEZ 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 RARL/RASL- JEZ condensing units are the result of an ongoing development program for improved efficiencies. With system SEER’s as high as 18.5, these units continue a tradition of delivering high efficiency. These units also contain the most advanced alternate refrigerant which contains no chlorofluorocarbons (CFCs), or hydro-chlorofluorocarbons (HCFCs), or other compounds that may leak from air conditioning systems and potentially harm the protective ozone layer of the Earth’s atmosphere. Additional Benefits The Comfort Control System™ The Comfort Control System™ provides on-board diagnostics and fault history by detecting system and electrical problems. It can also communicate system fault information to enabled thermostats. The integrated diagnostics with Active Protection™ prevents compressor operation when potentially harmful conditions are detected. Comfort Alert™ Diagnostics comes installed in each Rheem Prestige Series™ model. The 7-Segment LED Display is exclusive only to Rheem products. The information-display quickly and accurately shows technicians the source of malfunctions, to reduce time required for a repair. Operation A compressor sound blanket is standard to provide your unit with quieter unit operation. Units are equipped with a reliable Two-Stage operation for reliable, precise temperature control providing ultimate comfort. Air is discharged upward away from bushes and shrubs. The discharge pattern of the top grille provides minimum air restriction, resulting in quieter fan operation. Low Profile The industries lowest profile design at just 33 inch [864mm] maximum height makes the unit less noticeable in your yard and is easily installed leaving room for optional equipment and optimal access for maintenance. Cabinet and Design 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 all weather protection. The units are constructed with painted galvanized steel cabinets for added reliability and durability. All controls are accessible by removing one service panel. Removable top grille provides access to the condenser fan motor and condenser coil, for an easier time with service-ability. 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. Durability All models meet or exceed a 1000-hour salt spray test per ASTM B117 Standard Practice for Operating Salt Spray Testing Apparatus, to make sure they can withstand tough weather conditions.
