GENERAL DESCRIPTIONThe Rheem RRCF-, RREF- and RRGF- series rooftops are designed foroutdoor installation. Their cabinets and condenser base pans are powdercoat painted. Cabinets are fully insulated and gasketed to resist all types ofweather conditions. All models are shipped ready for downflow duct appli-cation requiring no additional labor to remove panels. For sideflow ducting,duct cap panels are easily repositioned in the field. Economizer and freshair damper accessories are designed for use in either duct configuration.The units are evacuated to remove moisture from the refrigeration system,precisely charged with the refrigerant and run tested at the factory prior toshipment.

RRGF-The combination rooftops provide comfort conditioning in all seasons. Twoseparate cooling circuits supply cool air to meet the demands of hot sum-mer days. One cooling circuit operates independently to satisfy the needson warm spring and fall days. The gas furnace furnishes two stages ofheat during cold winter weather. For those cool nights when full capacity isnot needed, the first stage heat operates to produce the right amount ofwarm air.

RREF-The electric heat models offer the same cooling characteristics and fea-tures as the gas heat models but factory installed electric heating elementswarm the building supply air. The electric heaters are designed for twostages of heat and are wired to balance the electrical load across the threephase power. Unit mounted terminal blocks and internal branch fusingallow single point external power wiring which eliminates the need for sep-arate power circuits to the electric heater and the cooling sections, thusreducing installation costs.

RRCF-The cooling only models deliver high efficiency cooling in two capacitysteps. A wide range of electric heat accessories can be field installed inthe unit to satisfy heating requirements. All operating parts of the unit areaccessible through exterior panels. The control components are mountedin one conveniently located control box. The control box and compressoraccess panel can be removed for servicing without interfering with con-denser air flow.

ACCESSORY DIMENSIONSROOFCURB (RXRK-E56)The roofcurb frames the roof openings and is designed to providea watertight connection between the unit and the roof. The curb isdesigned so that roof flashing and ducts may be installed prior toplacing unit.

The curb complies with the NationalRoofing Contractors Associationrequirements when installedas shown.

ECONOMIZER (RXRQ-FM56Z)This fully modulating economizer can introduce up to 100% of suit-able outdoor air to help satisfy cooling requirements. During theeconomizer cycle, the first stage compressor will be locked out totake advantage of free outdoor air cooling. If required, the secondstage room thermostat can cycle one compressor to maintainspace temperature. When the blower motor cycles off, the econo-mizer motor will close the low leak fresh air dampers to stop out-door air entry into the building.

Economizer is designed for use in either bottom or side ductapplications.

MANUAL FRESH AIR DAMPER(RXRF-CA56)The manual fresh air damper has a fixed damper that can beadjusted to allow 0% to 25% outside air into the unit to satisfyrequirements for minimum fresh air. Outside air enters the rainhood through cleanable filters and is regulated by an adjustabledamper mounted on a fixed panel.

RELIEF DAMPER (RXRP-E56)The relief damper is used to relieve positive building pressure. Arelief damper is normally used in conjunction with the economizeraccessory. It has a barometric type damper constructed of alu-minum with gasketed sealing edges. When the blower is off orrelief is not required, gravity forces the damper to close. Mountrelief damper in return duct on side return applications.

Note: For CSA approvedeconomizer voltage mustbe specified as follows:C—208/230 voltsD—460 voltsY—575 volts

SELECTION PROCEDURETo select an RRCF- Cooling unit, an RREF- Cooling and Electric Heating unit or RRGF- Cooling and Gas Heating unit to meet a jobrequirement, follow this procedure, with example, using data supplied in this specification sheet.

1. DETERMINE COOLING AND HEATING REQUIREMENTS AND SPECIFIC OPERATING CONDITIONS FROM PLANS AND SPECS.

Example: *Total cooling capacity— 135,000 BTUH [39.56 kW]*Sensible cooling capacity— 104,000 BTUH [30.48 kW]*Heating capacity— 195,000 BTUH [57.15 kW]*Condenser Entering Air— 95°F [35°C] DB*Evaporator Mixed Air Entering 65°F [18.3°C] WB; 78°F [25.6°C] DB*Indoor Air Flow (vertical) 4500 CFM [2124 L/s]*External Static Pressure .50 in. WG

2. SELECT UNIT TO MEET COOLING REQUIREMENTS.

Since total cooling is within the range of a nominal 12.5 ton [44 kW] unit, enter cooling performance table at 95°F [35°C] DB condenserinlet air. Interpolate between 63°F [17.2°C] and 67°F [19.4°C] to determine total capacity and power input for 65°F [18.3°C] FWB evap inletair at 5000 CFM [2360 L/s] indoor air flow (table basis):

Total Capacity = 143,150 BTUH [41.95 kW]Power Input (Compressor and Cond. Fans) = 13,900 Watts

Interpolate between 75°F [24°C] and 80°F [27°C] to determine sensible capacity at 78°F [25.6°C] FDB evaporator entering air:

Sensible Capacity = 115,000 BTUH [33.70 kW]

3. CORRECT CAPACITIES OF STEP 2 FOR ACTUAL AIR FLOW.

Select factors from airflow correction table at 4500 CFM [2124 L/s] and apply to data obtained in step 2 to obtain gross capacity:

Total capacity, 143,150 x .98 = 140,287 BTUH [41.11 kW]Sensible Capacity, 115,000 x .95 = 109,205 BTUH [32.00 kW]Power Input 13,900 x .99 = 13,761 Watts

These are Gross Capacities, not corrected for blower motor heat or power.

4. DETERMINE BLOWER SPEED AND WATTS TO MEET SYSTEM DESIGN.

Enter Indoor Blower performance table at 4500 CFM [2124 L/s]. Total ESP (external static pressure) per the spec of .50 in. includes the sys-tem duct and grilles. Add from the table “Component Air Resistance,” .065 for wet coil, .14 for vertical air flow, for a total selection static pres-sure of .705 inches of water, and determine:

RPM = 640WATTS = 1,020DRIVE = K (standard 2 H.P. motor)

5. CALCULATE INDOOR BLOWER BTUH HEAT EFFECT FROM MOTOR WATTS, STEP 4.

BTUH [L/s] = 1,020 x 3.412 = 3,480

6. CALCULATE NET COOLING CAPACITIES, EQUAL TO GROSS CAPACITY, STEP 3, MINUS INDOOR BLOWER MOTOR HEAT.

Net Total Capacity = 140,287 – 3,480 = 136,807 BTUH [40.09 kW]Net Sensible Capacity = 109,205 – 3,480 = 105,725 BTUH [30.98 kW]

7. CALCULATE UNIT INPUT AND JOB EER.

Total Power Input = 13,761 (step 3) + 1,020 (step 4) = 14,781 Watts

EER = Net Total BTUH [L/s] (step 6) = 136,807 = 9.26Power Input, Watts (above) 14,781

8. SELECT UNIT HEATING CAPACITY.

From Physical Data Table read that gas heating output (input rating x efficiency) is:

Heating Capacity = 200,000 BTUH [58.61 kW]

*NOTE: These operating conditions are typical of a commercial application in a 95°F [35°C]/79°F [26.1°C] design area with indoor design of 76°F [24.4°C]DB and 50% RH and 10% ventilation air, with the unit roof mounted and centered on the zone it conditions by ducts.
