Recreational Vehicle Generator

1.2GENERATOR APPLICABILITY

These generators have been designed and manufac- tured for supplying electrical power for recreational vehicles. Do not modify the generator or use it for any application other than for what it was designed. If there are any questions pertaining to its applica- tion, write or call the factory. Do not use the unit until advised by a competent authority.

1.4GENERATOR AC

CONNECTION SYSTEM

This generator set is equipped with dual stator AC power windings. These two-stator windings sup- ply electrical power to customer electrical loads by means of a two-wire connection system. Note, how- ever, that the neutral is bonded to the frame of the engine-generator.

DANGER

For fire safety, the generator must have been properly installed in compliance with ANSI 119.2-1975/NFPA 501C-1974, “Standard for Recreational Vehicles, Part III – Installation of Electrical Systems.” The generator also must have been installed in strict compliance with the manufacturer’s detailed installation instructions. After installation, do nothing that might render the unit in noncompliance with such codes, stan- dards and instructions.

Use this generator to supply electrical power for operating 120-volt, single-phase, 60 Hertz, AC elec- trical loads. These loads can require up to 3,400 watts (3.4 kW) of power, but cannot exceed 28.3 AC amperes of current at 120 volts.

Do not overload the generator. Some installa- tions may require that electrical loads be alter- nated to avoid overloading. Applying exces- sively high electrical loads may damage the generator and may shorten its life. Add up the rated watts of all electrical lighting, appliance, tool and motor loads the generator will power at one time. This total should not be greater than the wattage capacity of the generator. If an electrical device nameplate gives only volts and amps, multiply volts times amps to obtain watts (volts x amps = watts). Some electric motors require more watts of power (or amps of cur- rent) for starting than for continuous operation.

1.3SAFETY

Before attempting to use the generator set, care- fully read the “Safety Rules” section of this manual. Comply strictly with these rules to prevent accidents and damage to equipment and/or property. We sug- gest copying and posting the “Safety Rules” in poten- tial hazard areas of the vehicle. Stress safety to all operators and potential operators of this equipment.

The generator may have been installed so that it pow- ers 120-volt AC loads (Figure 1.1).

1.5SPECIFICATIONS

‹1.5.1 FUEL REQUIREMENTS

These generators are equipped with a liquefied petro- leum (LP) gas fuel system. LP gas is usually aupplied as a liquid in pressure tanks.

These generators require a “vapor withdrawal” type fuel system. This type of gaseous fuel system uses the vapors forming above the liquid fuel in the storage tank. Air temperature around the storage tank must be high enough to sustain adequate fuel vaporization. In colder climates, use of an independent heat source may be needed to be sure the fuel sufficiently vapor- izes in the storage tank.

LP gas may consist of propane, butane, or a mixture of the two gases. Propane vaporizes at tempertures as low as -20°F (-29°C), but butane returns to its liquid state when the temperature drops below about 32°F (0°C). For that reason, a higher ratio of propane is desired in the gas mixure when temperatures drop below freezing.
