Proper maintenance and care of your generator ensure a minimum number of problems and keep operating expenses at a minimum. See your Generac Authorized Service Dealer for service aids and acces- sories. HOW TO OBTAIN SERVICE...
Many accidents are caused by failing to follow simple and fundamental rules or precautions. Generac cannot possibly anticipate every possible cir cumstance that might involve a hazard. The warn- ings in this manual, and on tags and decals affixed to the unit, are, therefore, not all-inclusive.
Never work on the equipment when you are physically or mentally fatigued. • Inspect the generator regularly, and contact your nearest Generac Authorized Service Dealer immedi- ately for parts needing repair or replacement. • Before performing any maintenance on the genera- tor, disconnect its battery cables to prevent acci- dental start up.

This rule applies whether inlet air is brought in through an opening in the compartment door, an opening in the vehicle skirt, through duct- work, or by any other means. 26 Generac ® Power Systems, Inc. NOTE: Screening, louvers or expanded metal that cover air openings restrict airflow.
Section 2 – Installation PRIMEPACT 50 Recreational Vehicle Generator 2.3.4 TESTING THE INSTALLATION Generac recommends testing the installation to be sure adequate cooling airflow is available to the unit before placing the unit into service. If the unit shows signs of overheating, you will need to enlarge the air openings.
If the generator is to share the vehicle engine's tank, separate fuel pickup tubes are required for the engine and the generator. Generac recommends that you make the fuel pickup tube 2 to 3 inches (51 to 76 mm) shorter than the vehicle engine's pickup tube.
A lever attached to the diaphragm opens a valve to permit gas glow through the carburetor. Figure 2.16 – LP Gas Carburetion Diagram Generac NOTE: ® Power Systems, Inc. 29...
To test the system, you need a separate source of 12 volts DC to open the gaseous fuel solenoid valve. 30 Generac ® Power Systems, Inc. The leak test must comply fully with NFPA, Paragraph 318.
