These units offer comfort, energy conservation and dependability for single, multi-family and light commercial applications. The Rheem Classic XD RAMA- Condensing Units are the result of an ongoing development program for improved efficiencies. With 's ranging to 12.4, these units continue a tradilion of high efficiency 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. 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 o^ the discharge grille. The grille protects the motor windings and bearings from ram and snow All controls are accessible by removing one service panel. Removable top grille provides access to the condenser fan motor and condenser coil. Single speed motor designed for low speed, quiet. energy-saving operation 'CERTIFIED UNDER THE A R I CERTIFICATION PROGRAM A. R I STANDARD 210"

Scroll compressor is hermetically sealed and incorporates interna! high temperature motor overload protection, and durable insulation on the motor windings It is internally spring mounted and 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 wraparound louvered grille protects the coil from damage 5. Copper Tube Aluminum Fin coils are used on all models 6. The control box is located in the top corner of the cabinet providing for easy access through a service panel. 7. Service valves are standard on all models. 8. Power and control wiring are kept separate. 9. Every unit is factory charged and tested. 10. Separate compressor compartment for easy service access. 11. Drawn, painted base pan for extra corrosion resistance and sound reduction 12. RAMA- Series has a 10 year compressor limited warranty, factory installed low pressure control, high pressure control, compressor sound enclosure, and a liquid line filter drier 13. Anti-Short cycle time delay control Field Installed Accessories Low Ambient Switch Cycles outdoor fan to maintain adequate condensing pressures assuring liquid refrigerant flow to the coil. Allows indoor cooling with outdoor temperatures down to 0 o F. (Model No RXAD-A04) It is recommended that this control be installed in units to be operated at outdoor ambient temperatures under 70 o F.
