Safety Rules
PRIMEPACT 66G and 66LP Recreational Vehicle Generators
ELECTRICAL HAZARDS | FIRE HAZARDS |
•The generator covered by this manual produces dangerous electrical voltages and can cause fatal electrical shock. Avoid contact with bare wires, ter- minals, connections, etc., while the unit is running. Ensure all appropriate covers, guards and barriers are in place before operating the generator. If you must work around an operating unit, stand on an insulated, dry surface to reduce shock hazard.
•Do not handle any kind of electrical device while standing in water, while barefoot, or while hands or feet are wet. DANGEROUS ELECTRICAL SHOCK MAY RESULT.
•During installation onto the vehicle, properly ground (bond) the generator either by solid mount- ing to the vehicle frame or chassis, or by means of an approved bonding conductor. DO NOT connect the bonding conductor to any generator part that might be removed or disassembled during routine maintenance. If the grounding conductor must be replaced, use only a flexible conductor that is of No. 8 American Wire Gauge (AWG) copper wire minimum.
•If the vehicle electrical circuits can be powered by any other source of electricity (such as a “dock- side” power receptacle), there must be no possibil- ity of connecting the different power sources to the vehicle circuits at the same time. The dockside (utility) power source must be positively isolated from the vehicle circuits whenever the generator is operating. Failure to isolate the vehicle circuits from the dockside power supply when the genera- tor is running may result in damage to the genera- tor or serious injury or death to dockside (utility) power workers due to backfeed of electrical ener- gy.
•In case of accident caused by electric shock, imme- diately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor. AVOID DIRECT CONTACT WITH THE VICTIM. Use a nonconducting imple- ment, such as a rope or board, to free the victim from the live conductor. If the victim is uncon- scious, apply first aid and get immediate medical help.
•Never wear jewelry when working on this equip- ment. Jewelry can conduct electricity resulting in electric shock, or may get caught in moving com- ponents causing injury.
•For fire safety, the generator must be installed and maintained properly. Installation always must comply with applicable codes, standards, laws and regulations. Adhere strictly to local, state and national electrical and building codes. Comply with regulations the Occupational Safety and Health Administration (OSHA) has established. Also, ensure that the generator is installed in accordance with the manufacturer’s instructions and recommendations. Following proper installa- tion, do nothing that might alter a safe installation and render the unit in noncompliance with the aforementioned codes, standards, laws and regu- lations.
•Keep a fire extinguisher in the vehicle at all times. Extinguishers rated “ABC” by the National Fire Protection Association are appropriate for use on the recreational vehicle generator electrical system. Keep the extinguisher properly charged and be familiar with its use. If you have any question per- taining to fire extinguishers, consult your local fire department.
EXPLOSION HAZARDS 
•Do not smoke around the generator. Wipe up any fuel or oil spills immediately. Ensure that no com- bustible materials are left in the generator com- partment, or on or near the generator, as FIRE or EXPLOSION may result. Keep the area surround- ing the generator clean and free from debris.
•Gasoline is extremely FLAMMABLE and its vapors are EXPLOSIVE. Do not permit smoking, open flame, sparks or any source of heat in the vicinity while handling gasoline. Comply with all laws gov- erning the storage and handling of gasoline.
•Fuel lines must be properly installed and fastened, and free of leaks. There must be no possibility of gasoline vapors entering the vehi- cle interior.
•You are required to install an approved, flexible, nonconductive fuel line between the generator fuel connection point and rigid fuel lines.
•If the generator is equipped with a liquid propane (LP) gas fuel system, install the unit so it complies with all codes, standards and regulations pertain- ing to such systems. LP gas is highly explosive. The gas tends to settle in low areas where even the slightest spark can ignite it and cause an explo- sion. Do not allow gas vapors to enter the vehicle.
