FORM NO. P22-754 REV. 1 Supersedes Form No. P11-729 Rev. 8 HEAT PUMPS UPKB- SERIES Seven Models 10 SEER with efficiencies ranging up to 10.30 SEER in certain matched systems. Nominal Sizes 1 1 /2 to 5 Tons [5.28 to 17.58 kw] The Ruud Achiever Series UPKB- Heat Pump Outdoor units can provide year-round heating and cooling comfort for residential, multi-family and light commercial applications. They are designed to operate with Ruud indoor units with cooling and heating capacities certified in compliance with the ARI Certification program. The Ruud UBHC- Air Handler equipped with auxiliary heating elements for supplementary heat was designed especially for use with the UPKB- Heat Pump. Together they provide systems capable of delivering S.E.E.R. as high as 10.30 and HSPF s to 7.75. The following additional features, plus its energy-saving characteristics, make the UPKB- Heat Pump outdoor unit an excellent choice for new construction or upgrading your present system. Full wrap-around powder-painted louvered grille protects the coil from yard hazards and weather extremes. 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 fan motor to the underside of the discharge grille. The grille protects the motor windings and bearings from rain and snow. All models meet or exceed a 1000-hour salt spray test per ASTM B117 Standard Practice for Operating Salt Spray Testing Apparatus. *Patented. ENER UIDE Seasonal Energy Efficiency Ratio - SEER THIS MODEL 10.00 10.0 USES LESS ENERGY 17.0 ** CERTIFIED UNDER THE A.R.I. CERTIFICATION PROGRAMS A.R.I. STANDARD 240-81 **575V MODELS ARE NOT A.R.I.

All controls and compressor are accessible for servicing by removal of the service panel. Drawn Painted Base Pan. COPELAND SCROLL The Copeland scroll compressor is the key to efficiency for this Ruud 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 Copeland Scroll also has low start torque, eliminating start problems in the field. And its unique design enables the UPKB- Heat Pump unit to perform more efficiently. Engineering Features UPKB- Series Remote Heat Pumps 1. Scroll CompressorsIncorporate internal high temperature motor overload protection and durable insulation on the motor windings. They are externally mounted on rubber grommets to reduce vibration and noise. 2. Copper Tube/Aluminum Fin CoilsImproved heat transfer and corrosion resistance. 3. Strong, Attractive CabinetConstructed of powder painted steel providing protection to the condenser coil and a durable finish. 4. Demand Defrost Controls (featured on odd numbered models.) 5. Non-Cycling Reversing ValveEliminates discharge noises on each heating cycle. 6. Hot Gas MufflerReduces noise in heating cycle. 7. Suction Line AccumulatorProvides protection for the compressor. 8. Service Valves are standard on all models. 9. Refrigerant MeteringFlowcheck distributor. 10. Drawn, painted base pan reduces noise and vibration, and provides extra corrosion resistance. Accessories Low Ambient ControlAllows low temperature operation in the cooling cycle down to 0 F [ 18 C] outdoor temperature. It is recommended that this control be installed in units to be operated for cooling at outdoor ambient temperatures under 65 F [18 C]. (Model No. RXPZ-C01) Heat Pump MonitorIndicates inefficient operation or malfunction of heat pump. (Model No. RXPM-B01) Outdoor Thermostats RXPT-A01One outdoor thermostat in box.

Example 1: A 5 ton [17.58 kw] heat pump with a total line length of 100 feet [30.48 m] with a vertical separation of 93 feet [28.35 m] utilizing a 3 /8" [9.53 mm] liquid line: Table = 72 feet [21.95 m] maximum vertical separation for 100 feet [30.48 m] run. Separation exceeds table by (93-72) = 21 feet [6.40 m]. Therefore, reduce the indoor coil flow-check piston 2 + 2 = 4 sizes (For example, a #89 piston would reduce to a #85 piston). Increase the outdoor flow-check piston 2 + 2 = 4 sizes (For example, a #56 would increase to a #60). ➂ Do not exceed 120 feet [36.58 m] maximum vertical separation. ➃ No changes are required for expansion valve coils. ➄ Do not exceed table values for capillary tube coils. ➅ Always use the smallest liquid line possible to minimize system charge. ➆ For heat pumps with vertical separation: Route liquid line outside building Do not insulate liquid line. ➇ Chart may be used to size horizontal runs. NOTES: ➀ This chart is applicable for heat pumps. Heat pumps with any vertical separation require the use of standard line sizes only, due to the possibility of charge imbalance between heating and cooling modes. Example 1: A 3 ton [10.55 kw] heat pump with a total line length of 50 feet [15.24 m] can have a maximum vertical separation of 19 feet [5.79 m]. Do not increase line size to 3 /8" [9.53 mm]. ➁ This chart may also be used to size horizontal runs. Example 2: A 1.5 ton [5.28 kw] heat pump can have a total horizontal line length of 150 feet [45.72 m] when using the 5 /16" [7.94 mm] liquid line size. No vertical separation allowed. ➂ Do not exceed vertical separation as indicated on the chart. ➃ Always use the smallest liquid line possible to minimize system charge. ➄ No changes required for flow-check pistons or expansion valve coils.
