QUIETPACT™ 75D Recreational Vehicle Generator

1.2GENERATOR APPLICABILITY

These generators have been designed and manufac- tured for supplying electrical power to recreational vehicles. DO NOT modify the generator nor 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.

DANGER

For fire safety, the generator must have been properly installed in compliance with NFPA 70 (latest edition), “National Electrical Code”, Article 551, and NFPA 1192 (latest edition), “Standard for Recreational Vehicles”. The gen- erator 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 noncom- pliance with such codes, standards, and instruc- tions.

Use this generator to supply electrical power for operating 120/240-volt, single-phase, 60-Hertz, AC electrical loads. These loads can require up to 7,500 watts (7.5 kW) of power, but cannot exceed 62.5 AC amps of current at 120 volts, or 31.2 AC amps at 240 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 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 current) for starting than for continuous operation.

1.3SAFETY

Before attempting to use the generator set, carefully 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.

1.4GENERATOR AC

CONNECTION SYSTEM

This generator is equipped with dual-stator AC power windings. These two-stator windings supply electrical power to customer electrical loads by means of a dual, two-wire connection system. Note, however, that the neutral is grounded.

The generator may have been installed so that it pow- ers 120- and/or 240-volt AC electrical loads (Figure 1.1). It can be rewired to connect 120-volt AC electri- cal loads only. This procedure should be done by a Generac Authorized Service Dealer or other qualified installer. Refer to the installation portion of this man- ual for more information.

1.5SPECIFICATIONS

◆1.5.1 FUEL REQUIREMENTS

The generator is equipped with a diesel fuel system. Use clean, fresh No. 1D or No. 2D diesel fuel with minimum Cetane number of 40. The diesel fuel must also conform to American Society of Testing and Materials (ASTM) specifications. Never use any dirty or contaminated fuel. When adding fuel, DO NOT overfill the tank. Allow room at the top of the tank for fuel expansion. Depending on the installation, the generator may have either a separate fuel tank or “share” the vehicle’s engine fuel tank.

NOTE:

Some installations using a “shared” fuel tank may have a generator fuel pickup tube that is shorter than the vehicle’s engine pickup tube. Such an arrangement causes the generator engine to “run out of fuel”, while adequate fuel for the vehicle engine remains in the tank.

Also, appropriate care should be taken in applica- tions where extremely low ambient temperatures are possible, to ensure the temperature of the diesel fuel is not allowed to fall below levels where “gelling” could occur
