Primepact 50 & 50LP RV Owner's Manual D7431 - Electric Generators

Section 1 – General InformationPRIMEPACT 50 Recreational Vehicle Generator!Generac does not recommend using anygasoline containing alcohol (such as “gasohol”).If you use any gasoline containing alcohol, itmust not contain more than 10 percent ethanol,and it must be removed from the generatorduring storage. Do NOT use any gasolinecontaining methanol. If you use gasoline withalcohol, inspect more frequently for fuel leaksand other abnormalities.◆ 1.5.2 OPTIONAL PROPANE FUEL SYSTEMThe PRIMEPACT 50LP series generator is equippedwith a liquid propane (LP) gas fuel system. LP gas isusually supplied as a liquid in pressure tanks.PRIMEPACT series generators require a vapor withdrawaltype fuel system. This type of gaseous fuel systemuses the vapors forming above the liquid fuel inthe storage tank. Air temperature around the storagetank must be high enough to sustain adequate fuelvaporization. In colder climates, you may need to usean independent heat source to be sure the fuel sufficientlyvaporizes in the storage tank.LP gas may consist of propane, butane or a mixtureof the two gases. Propane vaporizes at temperaturesas low as -20° F (-29° C), but butane returns to its liquidstate when the temperature drops below about32° F (0° C). For that reason, a higher ratio ofpropane is desired in the gas mixture when temperaturesdrop below freezing.◆1.5.3 FUEL CONSUMPTIONModel No Load 1/2 Load Full LoadPRIMEPACT 50 0.32 0.46 0.76(02010-2)PRIMEPACT 50 LP 0.47/17.05 0.72/3.06 1.25/45.35(04164-2)Gasoline is in gal/h.LP is in gal/h and cf/h.◆1.5.4 ENGINE OIL REQUIREMENTSUse only high quality detergent oil rated withAmerican Petroleum Institute (API) ServiceClassification SF, SG or SH. The recommended oilweights include the following:• During summer months: SAE 30. An acceptablesubstitute is SAE 10W-30.• During winter months: SAE 5W-30. DO NOT USESAE 10-W40.Crankcase and oil filter capacity is approximately1,400 mL or 1.5 U.S. quarts. Do NOT use specialadditives. See Sections 3.1 and 3.2 (Page 12) for oillevel check and fill procedures.6 Generac ® Power Systems, Inc.1.5.5 ENGINE◆Type of Engine ....................................GN-410, Single-cylinderCooling Method..........................................................Air-cooledRated Horsepower ..........................................15 @ 4,200 rpmDisplacement....................................................................407ccCylinder Block ..........................Aluminum w/Cast Iron SleeveType of Governor ..............................Mechanical, Fixed SpeedAir Cleaner..........................Paper Element w/Foam PrecleanerStarter..........................................................12-volt DC ElectricIgnition System........................Solid-state w/Flywheel MagnetoRecommended Spark PlugChampion ..................................................................RC12YCAC....................................................................................R45SFram Autolite ......................................................................65Spark Plug Gap ........................................0.030 inch (76 mm)Recommended Minimum Battery ..............400 Cold-crankingAmperes◆ 1.5.6 GENERATORRated Maximum ContinuousAC Output (Gasoline) ............................4,800 Watts (4.8 kW)AC Output (LP Fuel) ..............................4,500 Watts (4.5 kW)Rated Voltage ......................................................120 Volts AC*Rated Maximum ContinuousAC Current (Gasoline) ......................................40 Amperes**AC Current (LP Fuel) ....................................37.5 Amperes**Phase ................................................................................SingleRotor RPM ........................................................................3,600Number of Rotor Poles ............................................................2Engine RPM ......................................................................2,571Rated AC Frequency ........................................................60 HzBattery Charge Voltage............................................14 Volts DCBattery Charge Current..................................2 Amperes (max)WeightGasoline................................................................198 PoundsLP Fuel..................................................................200 PoundsLength ....................................................25.5 inches (648 mm)Width....................................................18.88 inches (479 mm)Height ..................................................16.75 inches (425 mm)*All units are reconnectable to 120- and/or 240-volt, dual voltageoutput.
