Generac NP-50LPG Recreational Vehicle Generator

The voltage regulator also incorporates a “voltage surge pro- tection circuit.” This circuit prevents troublesome surges in the generator AC output voltage. Voltage surge is a common cause of damage to electronic equipment.

25-HOUR BREAK IN PERIOD

The first 25 hours of operation is the break-in period for the generator. Properly breaking in the generator is essential to minimize fuel consumption and provide maximum engine per- formance. During this 25-hour break in period, follow this procedure:

•Run the unit at varying electrical loads, to help seat engine piston rings properly.

•For the 75-hour operation following the break in period, avoid light electrical loads. Load the generator at 50% (or more) of its rated wattage capacity. Repeated light loads during these 75 hours can cause improper seating of engine piston rings, resulting in blowby and high oil consumption.

•Check engine oil level frequently. Add oil if needed. It is normal for the generator engine to consume more oil than is normal until the piston rings have properly seated.

ATTENTION REQUIRED AFTER SUB- MERSION

If the recreational vehicle generator has been submerged in water, it must NOT be started or operated. Following any sub- mersion in water, have an authorized Generac Service Facility thoroughly clean and dry the generator.

OPERATING PRECAUTIONS

Never operate the generator set while the vehicle is parked over dry leaves, dry grass or any other combustible substance. The generator’s exhaust system becomes extremely hot and can cause fire if it is too close to combustible materials.

The generator’s exhaust system gives off DEADLY carbon monoxide gas. this dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness and even death. never operate the generator set with the vehicle inside any garage or enclosed area. Never operate the generator if it has a leaky exhaust system. Close windows in the vicinity of the generator exhaust outlet and take any other steps to prevent exhaust gases from entering rooms or areas occupied by people or animals.

•After operating the unit for 25 hours, complete the tasks rec- ommended under “25-Hour Check Up.”

25-HOUR CHECK UP

After the 25-hour break-in period, contact an authorized ser- vice facility for the following maintenance. The vehicle owner is responsible for any charges:

•Change engine crankcase oil and oil filter. Check oil level.

•Inspect cooling and ventilation openings. Check engine carburetor.

•Check engine ignition system.

•Inspect entire electrical system.

•Inspect the engine exhaust system.

EFFECTS OF MOISTURE AND DIRT

Keep the generator set as clean and dry as possible. Protect the unit against excessive dust, dirt, corrosive vapors, road splash, etc. Permitting dirt and moisture to accumulate on generator windings will have an adverse effect on the insula- tion resistance of those windings.

When moisture is allowed to remain in contact with windings, some of the moisture will be retained in voids and cracks in the insulation. This causes a reduced insulation resistance and will eventually cause problems. Dirt will make the problem worse, since dirt tends to hold moisture in contact with wind- ings. Salt (as from sea air) will also worsen the problem since it tends to absorb moisture from the air. Salt and moisture, when combined, form a good electrical conductor.

OPERATION IN HIGH GRASS

OR BRUSH

WARNING: NEVER OPERATE THE GENERATOR

WHILE THE VEHICLE IS PARKED IN HIGH GRASS,

WEEDS, BRUSH OR LEAVES. SUCH MATERIALS

CAN IGNITE AND BURN FROM THE HEAT OF THE

EXHAUST SYSTEM. THE GENERATOR EXHAUST

BECOMES EXTREMELY HOT DURING OPERATION

AND REMAINS HOT FOR A LONG TIME AFTER IT

HAS SHUT DOWN.
