Section 1 – General Information
QUIETPACT™ 75D Recreational Vehicle Generator
1.2 GENERATOR 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.
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.
1.3 SAFETY
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.
1.4 GENERATOR 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.

1.5 SPECIFICATIONS
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
