Safety Rules
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe
operation be copied and posted in potential hazard areas of the recreational vehicle.
Safety should be stressed to all operators and potential operators of this equipment.

!
!

WARNING:

The engine exhaust from this product
contains chemicals known to the state
of California to cause cancer, birth
defects or other reproductive harm.

WARNING:

This product contains or emits chemicals
known to the state of California to cause
cancer, birth defects or other reproductive harm.
Study these SAFETY RULES carefully before
installing, operating or servicing this equipment.
Become familiar with this manual and with the unit.
The generator can operate safely, efficiently and reliably only if it is properly installed, operated and
maintained. Many accidents are caused by failing to
follow simple and fundamental rules or precautions.
Generac cannot possibly anticipate every possible
circumstance that might involve a hazard. The warnings in this manual, and on tags and decals
affixed to the unit, are, therefore, not all-inclusive. If
you use a procedure, work method or operating technique Generac does not specifically recommend, you
must satisfy yourself that it is safe for you and others.
You also must make sure the procedure, work
method or operating technique that you choose does
not render the generator unsafe.

DANGER

Despite the safe design of this generator,
operating this equipment imprudently, neglecting its maintenance or being careless can cause
possible injury or death. Permit only responsible and capable persons to operate or maintain
this equipment.
Potentially lethal voltages are generated by
these machines. Ensure all steps are taken to
render the machine safe before attempting to
work on the generator.

Parts of the generator are rotating and/or hot
during operation. Exercise care near running
generators.

Generac® Power Systems, Inc.

! GENERAL HAZARDS !
• For safety reasons, Generac recommends
that the installation, initial start-up and maintenance of this equipment is carried out by a
Generac Authorized Service Dealer.
• The generator engine releases DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death.
Never operate the generator set with the vehicle
inside any garage or other enclosed area. DO NOT
OPERATE THE GENERATOR IF THE EXHAUST
SYSTEM IS LEAKING OR HAS BEEN DAMAGED.
SYMPTOMS OF CARBON MONOXIDE POISONING ARE (a) inability to think coherently, (b) nausea, (c) vomiting, (d) twitching muscles, (e) throbbing temples, (f) dizziness, (g) headaches, (h)
weakness, and (i) sleepiness. IF YOU EXPERIENCE ANY OF THESE SYMPTOMS, MOVE INTO
FRESH AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET MEDICAL HELP. Shut down the generator and do not operate it until it has been inspected and repaired.
• Never sleep in the vehicle while the genset is running unless the vehicle has a working carbon
monoxide detector. The exhaust system must be
installed in accordance with the genset installation
manual. Make sure there is ample fresh air when
operating the genset in a confined area.
• Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts. Never
remove any drive belt or fan guard while the unit is
operating.
• Adequate, unobstructed flow of cooling and ventilating air is critical to correct generator operation
and is required to expel toxic fumes and fuel
vapors from the generator compartment. Without
sufficient cooling airflow, the engine/generator
quickly overheats, which causes serious damage to
the generator. Do not alter the installation or permit even partial blockage of ventilation provisions,
as this can seriously affect safe operation of the
generator.
• When working on this equipment, remain alert at
all times. Never work on the equipment when you
are physically or mentally fatigued.
• Inspect the generator regularly, and contact your
nearest Generac Authorized Service Dealer immediately for parts needing repair or replacement.

Safety Rules
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

• Before performing any maintenance on the generator, disconnect its battery cables to prevent accidental start up. Disconnect the cable from the battery post indicated by a NEGATIVE, NEG or (–)
first. Reconnect that cable last.
• Never use the generator or any of its parts as a
step. Stepping on the unit can stress and break
parts, and may result in dangerous operating conditions from leaking exhaust gases, fuel leakage,
oil leakage, etc.

ELECTRICAL HAZARDS
• The generator covered by this manual produces
dangerous electrical voltages and can cause fatal
electrical shock. Avoid contact with bare wires, terminals, 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, have the generator properly grounded (bonded) either by solid
mounting to the vehicle frame or chassis, or by
means of an approved bonding conductor. DO
NOT disconnect the bonding conductor, if so
equipped. DO NOT reconnect 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.
• In case of accident caused by electric shock, immediately 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 implement, such as a rope or board, to free the victim
from the live conductor. If the victim is unconscious, apply first aid and get immediate medical
help.
• Never wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving components causing injury.

FIRE HAZARDS
• 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 installation, do nothing that might alter a safe installation
and render the unit in noncompliance with the
aforementioned codes, standards, laws and regulations.
• 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
pertaining to fire extinguishers, consult your local
fire department.

GENERATOR APPLICABILITY

These generators have been designed and manufactured for supplying electrical power for recreational
vehicles. You should 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
application, write or call the factory. Do not use the
unit until you have been advised by competent
authority.

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, standards and instructions.
You can use your generator set to supply electrical
power for operating one of the following electrical
loads:
• QUIETPACT 55G & LP: 120 and/or 240 volts, single phase, 60 Hz electrical loads. These loads can
require up to 5500 watts (5.5 kW) of total power,
but cannot exceed 45.8 AC amperes of current at
120 volts or exceed 22.9 AC amperes at 240 volts.
• QUIETPACT 65G & LP: 120 and/or 240 volts, single phase, 60 Hz electrical loads. These loads can
require up to 6500 watts (6.5 kW) of total power,
but cannot exceed 54.1 AC amperes of current at
120 volts or exceed 27 AC amperes at 240 volts.
• QUIETPACT 75G & LP: 120 and/or 240 volts, single phase, 60 Hz electrical loads. These loads can
require up to 7500 watts (7.5 kW) of total power,
but cannot exceed 62.5 AC amperes of current at
120 volts or exceed 31.2 AC amperes at 240 volts.

Do not overload the generator. Some installations may require that electrical loads be alternated to avoid overloading. Applying excessively 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 current) for starting than for continuous operation.

1.3

INSTALLATION

This Owner’s Manual has been prepared under the
assumption that a competent, qualified technician
installed the generator into a recreational vehicle. We
also assume the installer complied with all applicable
codes, standards and regulations pertaining to installation.
An INSTALLATION MANUAL was shipped with the
generator. That Manual contains manufacturer’s
instructions and recommendations for installing the
unit into an industrial vehicle. After installation,
installers should forward the Installation Manual to
Owners/Operators for their information.
Owners/Operators have the responsibility to make
sure that nothing is done that might render the installation unsafe or in non-compliance with applicable
codes, standards and instructions.

1.4

SAFETY

Before using the generator set, carefully read GENERAL SAFETY RULES inside the cover. Comply with
these RULES to prevent accidents and damage to
equipment and/or property. Generac suggests copying and posting the GENERAL SAFETY RULES to
potential operators of this equipment.

1.5

GENERATOR AC CONNECTION
SYSTEM

These air-cooled generator sets are equipped with
dual stator AC power windings. These two stator
windings supply electrical power to customer electrical loads by means of a dual 2-wire connection system.
Generators may be installed to provide the following
outputs:
1. 120 VAC loads only — one load with a maximum
total wattage requirement equal to the generator’s
rated power output (in watts), and 120V across
the generator output terminals. Figure 1.1, page
6, shows the generator lead wire connections for
120VAC ONLY.
2. 120/240 VAC loads — one load with a maximum
total wattage requirement equal to the generator’s
rated power output, and 240V across the generator output terminals; or two seperate loads, each
with a maximum total wattage requirement equal
to half of the generator’s rated power output (in
watts), and 120V across the generator output terminals. Figure 1.2, page 6, shows the generator
lead wire connections for 120/240 VAC loads.
Also refer to section 2.1.4 Line Breakers for circuit breaker ratings.
This procedure should be done by a Generac
Authorized Service Dealer or other qualified installer.

NOTE
Some installations using a “shared” fuel tank may
have a generator fuel pickup tube that is shorter
than the vehicle engine’s pickup tube. Such an
arrangement causes the generator engine to “run
out of gas” while adequate fuel for the vehicle
remains in the tank.
To reduce lead and carbon deposits use high quality
UNLEADED gasoline with the generator. Leaded
REGULAR grade gasoline is an acceptable substitute.
NOTE:
Using unleaded gasoline contributes to longer engine
valve life by reducing lead and carbon deposits.

Generac does not recommend using any
gasoline containing alcohol (such as “gasohol”).
If you use any gasoline containing alcohol, it
must not contain more than 10 percent ethanol,
and it must be removed from the generator
during storage. Do NOT use any gasoline
containing methanol. If you use gasoline with
alcohol, inspect more frequently for fuel leaks
and other abnormalities.

◆ 1.6.2 ENGINE OIL REQUIREMENTS

SPECIFICATIONS

◆ 1.6.1 FUEL REQUIREMENTS (GASOLINE)
This generator is equipped with a gasoline fuel system
as standard equipment. Specific installations may provide either a separate fuel tank for the generator, or the
generator may “share” the vehicle engine’s fuel tank.

Use only high quality detergent oil classified “For
Service SF” and with an oil viscosity rating of SAE
10W-30 oil. Do not pour in any additives to the recommended oil. Engine crankcase capacity is 1.8

◆ 1.6.5 EMISSIONS COMPLIANCE PERIOD
For nonhandled engines the Emissions Compliance
Period referred to on the Emissions Compliance
Label indicates the number of operating hours for
which the engine has been shown to meet Federal
emission requirements.
• For engines less than 225 cc displacement,
Category C=125 hours, B=250 hours, and A=500
hours.
• For engines of 225 cc or more, Category C=250
hours, B=500 hours, and A=1000 hours.

◆ 2.1.2 START/STOP SWITCH
To crank and start the engine, hold this switch in the
START position. Release the switch when the engine
starts. To stop an operating engine, press and hold
the switch in the STOP position until the engine shuts
off. The switch center position is the RUN position.

◆ 2.1.3 7.5 AMP FUSE
The fuse protects the engine’s DC control circuit
against electrical overload. If the fuse element has
melted open due to overloading, the engine cannot be
cranked. If you must replace the fuse, use only an
identical 7.5 amp replacement fuse.

◆ 2.1.4 LINE BREAKERS
Protects generator’s AC output circiut against
overload, i.e., prevents unit from exceeding
wattage/amperage capacity. The circuit breaker ratings are as follows:

NOTE:
If this generator has been reconnected for dual
voltage AC output (120/240 volts), you can install
line breakers having an amperage rating that is
different than that stated above. The replacement
line breakers consist of two separate breakers with
a connecting piece between the breaker handles
(so that both breakers will operate at the same
time). If the unit is reconnected for dual voltage,

OPTIONAL REMOTE
START/STOP PANEL

A remote mounted Start/Stop Panel (Figure 2.2) is
available that allows you to start and stop the generator engine conveniently from inside the vehicle. The
remote panel includes a Start/Stop switch, hourmeter, generator run lamp and a wire harness.

Figure 2.2 — Optional Remote Panel
(Models 004057 and 004184)

◆ 2.4.1 INSTALLATION
Generator installation must have been properly completed so it complies with all applicable codes, standards and regulations and with the manufacturer's
recommendations.

◆ 2.4.2 ENGINE LUBRICATION
Have the engine crankcase properly serviced with the
recommended oil before starting. Refer to Section
1.6.3 (Page 6) and Sections 3.1 and 3.2 (Page 11) for
oil servicing procedures and recommendations.

Any attempt to crank or start the engine before
you have properly serviced it with the recommended oil may result in an engine failure.

◆ 2.4.3 FUEL SUPPLY

2.3

AUTOMATIC CHOKE

This engine is equipped with an automatic choke that
consists of two main components: a choke solenoid
and prechoke.

◆ 2.3.1 CHOKE SOLENOID
During engine cranking (Start/Stop switch at
START), a solid-state choke module signals the
choke solenoid to activate and cycle (choke on/choke
off) until the engine starts. The choke solenoid thus
opens and closes the carburetor choke valve only
when the engine is cranking. When the engine starts,
the choke stops cycling.

◆ 2.3.2 PRECHOKE
The choke system also has a temperature-sensitive
metal strip that adjusts choke valve angle according
to ambient temperatures (i.e., in cold ambient temperatures, choke valve closes more). Once the engine
starts, an element heats the temperature-sensitive
strip to a normal operating condition, opening the
choke valve. This may take about three minutes in
cooler weather.

2.4

BEFORE STARTING THE ENGINE
NOTE:

Instructions and information in this manual
assume the generator has been properly installed,
connected, serviced, tested and adjusted by a
qualified installation technician or installation
contractor.

Generac® Power Systems, Inc.

The engine must have an adequate supply of proper
fuel to operate. Before starting it, check that sufficient
fuel is available.
NOTE:
Depending on the installation, the generator may
have either a separate fuel tank, or it may “share”
the vehicle engine’s fuel tank.

◆ 2.4.4 COOLING AND VENTILATING AIR
Air inlet and outlet openings in the generator compartment must be open and unobstructed for continued proper operation. Without sufficient cooling and
ventilating airflow, the engine/generator quickly overheats, which causes it to shut down and may damage
the generator.

◆ 2.4.5 ENGINE EXHAUST GAS
Before starting the generator engine, you should be
sure there is no way for exhaust gases to enter the
vehicle interior and endanger people or animals.
Close windows, doors and other openings in the vehicle that, if open, might permit exhaust gases to enter
the vehicle.

Section 2 – Operation
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

DANGER

The generator engine releases DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even
death. Never operate the generator set with
the vehicle inside any garage or other enclosed
area. DO NOT OPERATE THE GENERATOR IF THE
EXHAUST SYSTEM IS LEAKING OR HAS BEEN
DAMAGED. SYMPTOMS OF CARBON MONOXIDE POISONING ARE (a) inability to think coherently, (b) nausea, (c) vomiting, (d) twitching
muscles, (e) throbbing temples, (f) dizziness, (g)
headaches, (h) weakness, and (i) sleepiness. IF
YOU EXPERIENCE ANY OF THESE SYMPTOMS,
MOVE INTO FRESH AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET MEDICAL HELP. Shut down
the generator and do not operate it until it has
been inspected and repaired.

DANGER

2.5

Never sleep in the vehicle while the genset is
running unless the vehicle has a working carbon
monoxide detector. The exhaust system must be
installed in accordance with the genset installation manual. Make sure there is ample fresh air
when operating the genset in a confined area.

STARTING THE GENERATOR
NOTE:

Read the vehicle manufacturer’s instructions. The
owner/operator should become familiar with the
vehicle in which this generator is installed.
Differences exist between vehicles. For example,
some vehicles may use a transfer switch to isolate
dockside power from the generator, while other
vehicles may use an isolating receptacle. Some
vehicles may be equipped with a DC converter
which allows the generator to power certain DC
lighting and other DC loads.
To crank and start the generator engine, proceed as
follows:
1. Turn OFF electrical loads using the means provided in your vehicle (such as a main line circuit
breaker or transfer switch).
NOTE:

2. If you have not started the engine in more than
two weeks, press the Fuel Pump Primer switch
and hold it for about 10 seconds. However, if the
engine is warm, skip Step 2.
3. To crank and start the engine, hold the start/stop
switch at START. Release the switch when the
engine starts.

If the engine does not start after it has been
cranking for 15 seconds, release the Start/Stop
switch and wait 1 minute before trying again.
Holding the switch for longer than 15 seconds
can damage the starter motor.
4. Let the engine run at no-load for a few minutes to
stabilize and warm up.
5. Turn ON electrical loads using the means
provided (such as a main circuit breaker or
transfer switch).

2.6

STOPPING THE GENERATOR

1. Turn OFF all electrical loads using the means
provided (such as a main circuit breaker or
transfer switch).
2. Let generator run at no-load for a few minutes, to
stabilize internal engine generator temperatures.
3. Place the Start/Stop switch in its STOP position.
The engine will come to a complete stop.

2.7

APPLYING LOADS TO GENERATOR

When applying electrical loads to the generator,
observe these guidelines:
• Before applying electrical loads, let the generator
stabilize and warm up for a minute or two.
• DO NOT overload the generator.

◆ 2.7.1 LETTING THE ENGINE STABILIZE
The generator supplies correct rated voltage only at
the proper governed speed. Some electrical appliances may be extremely sensitive to voltage. Incorrect
voltages can damage such appliances.
If electrical loads are applied at reduced operating
speeds, such loads imposed on the engine when sufficient power is not available may shorten engine life.
Never turn ON electrical loads until after the generator engine has started and stabilized at no-load.

If starting from the generator control panel, turn
OFF loads by setting the generator’s main circuit
breaker to the OFF (or open) position. If starting
from a remote panel, turn OFF loads using the
means provided in the vehicle (such as a main circuit breaker). Electrical load circuits will be
turned ON after the generator has started, stabilized and warmed up.
Generac® Power Systems, Inc.

Section 2 – Operation
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

◆ 2.7.2 DO NOT OVERLOAD THE GENERATOR
You can read the rated wattage/amperage capacity of
your generator on the generator data decal (see
Section 1.1 on Page 4).
Applying electrical loads in excess of the unit’s rated
capacity will cause the engine/generator to automatically shut down.
To avoid overloading, add up the wattage of all connected electrical lighting, appliance, tool and motor
loads. This total should not be greater than the generator’s rated wattage capacity.
• Most lighting, appliance, tool and motor loads indicate their required watts on their nameplate or
data plate. For light bulbs, simply note the wattage
rating of the bulb.
• If a load does not show its rated wattage, multiply
that load’s rated VOLTS times AMPS to obtain
WATTS.
• Induction type motors (such as those that run the
vehicle’s furnace fan, refrigerator, air conditioner,
etc.) need about 2-1/2 times more watts of power
for starting than for running (for a few seconds
during motor starting). Be sure to allow for this
when connecting electrical loads to the generator.
First, figure the watts needed to start electric
motors in the system. To that figure, add the running wattages of other items that will be operated
by the generator.
• Do not apply heavy electrical loads for the first two
or three hours of operation.

2.8

PROTECTION SYSTEMS

◆ 2.8.1 LOW OIL PRESSURE SWITCH
This switch (Figure 2.3) has normally closed (N.C.)
contacts that are held open by engine oil pressure
during cranking and operating. Should oil pressure
drop below a preset level, switch contacts close, and
the engine automatically shuts down. The unit should
not be restarted until oil is added.

10 Generac® Power Systems, Inc.

◆ 2.8.2 HIGH TEMPERATURE SWITCH
This switch (Figure 2.3), which has normally open
(N.O.) contacts, is mounted near the oil filter. The
contacts close if the temperature should exceed
approximately 270º F (132º C) for gasoline models,
and 284° F (140° C) for LP models, initiating an
engine shutdown.

Figure 2.3 – Low Oil Pressure and
High Temperature Switches

◆ 2.8.3 FIELD BOOST
The Controller Circuit Board houses a field boost
diode and resistor that are not part of the automatic
choke circuit. These two components are part of a
“field boost” circuit (Figure 2.4). During engine
cranking only, a positive DC (battery) voltage is delivered through a diode, resistor, brushes, slip rings,
and the generator rotor. Application of this voltage to
the rotor “flashes the field” whenever it is started.
Flashing of the field each time the generator starts
makes sure that a sufficiently strong magnetic field is
available to produce “pickup” voltage in the stator
windings.

Figure 2.4 – Field Boost Circuit

Section 3 – Maintenance
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

◆ 2.8.4 OVERVOLTAGE PROTECTION
A solid-state voltage regulator (Figure 2.5) controls
the generator’s AC output voltage. This regulator supplies an excitation current to the rotor. By regulating
the rotor’s excitation current, the strength of its magnetic field is regulated and, in turn, the voltage delivered to connected electrical loads is controlled. When
the AC frequency is 60 Hertz, voltage is regulated at
115 volts.

Figure 2.5 – Solid State Voltage Regulator

◆ 2.8.6 25-HOUR CHECK-UP
After the 25-hour break-in period, contact a Generac
Authorized Service Dealer for the following maintenance. (The vehicle owner is responsible for any
charges relating to normal unit maintenance.)
•
•
•
•
•
•

Change the engine crankcase oil and oil filter.
Check all fluid levels.
Inspect the cooling and ventilation openings.
Check the engine ignition system.
Inspect the entire electrical system.
Inspect the engine exhaust system.

◆ 2.8.7 OPERATION IN HIGH GRASS

OR BRUSH

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

◆ 2.8.5 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 performance. During this 25hour break-in period, follow this procedure:
• Run the unit at varying electrical loads to help seat
the engine piston rings properly.
• Check the 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.
• For the 75-hour operation following the break-in
period, avoid light electrical loads. Load the
generator at 50 percent (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.
• After operating the unit for 25 hours, complete the
tasks recommended under Section 2.8.6.

Never operate the generator while the vehicle
is parked over high grass, weeds, brush,
leaves or any other combustible substance.
Such materials can ignite and burn from the
heat of the exhaust system. The generator
exhaust system becomes extremely hot during operation and remains hot for a long time
after it has shut down.

3.1

CHECKING THE ENGINE OIL
LEVEL

For oil capacities and requirements, see “Engine Oil
Requirements,” Section 1.6.2 (Page 6). Check the
engine crankcase oil level at least every eight hours of
operation, or before you use it. To check the engine
oil level, proceed as follows (see Figure 3.1):
1. Be sure the generator is as level as possible.
2. Remove the dipstick and wipe it dry with a clean,
lint-free cloth.
3. Install and tighten the dipstick cap; then, remove
it again. The oil level should be at the dipstick
“Full” mark.
4. If necessary, remove the oil fill cap on the rocker
cover and slowly add oil until it reaches the dipstick “Full” mark. DO NOT FILL ABOVE THE
“FULL” MARK.

Never operate the engine with the oil level
below the “Add” mark on the dipstick. Doing
this could damage the engine.
5. Install and tighten the oil fill cap and the dipstick
before operating the engine.

3.2

CHANGING THE ENGINE OIL
AND/OR OIL FILTER

9. Start the engine and check for leaks.

Figure 3.2 — Engine Oil Filter

• Change the engine oil after the first 25 hours of
operation (after the 25-hour break-in period, see
Section 2.8.5, Page 10). Thereafter, change the
oil every 100 operating hours. Change the oil more
frequently if operating consistently under heavy
load or at high ambient temperatures.
• Change the engine oil filter after the first 25 hours
of operation, and every 100 operating hours thereafter.
To change the oil and/or oil filter, proceed as
follows:
1. Run the engine until it is thoroughly warmed up
(at least five minutes) then shut OFF the engine.
2. With the engine still warm from running, remove
the oil drain plug (Figure 3.1). Drain the oil into
a suitable container.

MAINTAINING THE ENGINE
AIR CLEANER

◆ 3.3.1 CLEANING THE FOAM PRECLEANER
Clean and re-oil the foam precleaner every three
months or every 25 hours of operation, whichever
occurs first. Service the foam precleaner more frequently if operating the generator in extremely dusty
or dirty conditions. Use the following procedure
(Figure 3.3):

Oil Drain Hose
3. After the oil has drained, replace the oil drain
plug. (If only changing the oil, go to step 7.)
4. With the oil drained, remove the old oil filter by
turning it counterclockwise (Figure 3.2).
5. Apply a light coating of clean engine oil to the gasket of the new filter.
6. Screw the new filter on by hand until its gasket
lightly contacts the oil filter adapter. Then, tighten the filter an additional 3/4 to one turn.
7. Remove the dipstick and fill crankcase with the
proper type and amount of recommended oil (see
Section 1.6.2, Page 6). The engine crankcase can
hold about 1.8 liters or 1.9 quarts with oil filter
change. DO NOT FILL ABOVE THE “FULL”
MARK.
8. Install and tighten the dipstick before operating
the engine.
12 Generac® Power Systems, Inc.

1. Turn the knob counterclockwise to loosen.

CLEAN SPARK ARRESTOR

The engine exhaust muffler has a spark arrestor
screen. Inspect and clean the screen every 50 hours
of operation or once each year, whichever comes first.
NOTE:
If you use your generator on any forest-covered,
brush-covered or grass-covered unimproved land,
it must equipped with a spark arrestor. The spark
arrestor must be maintained in good condition by
the owner/operator.
Clean and inspect the spark arrestor as follows:
• Remove the screen retaining bracket by removing
the screw.
• Slide the spark arrestor screen out from the tail
pipe.
• Inspect screen and replace if torn, perforated or

CLEANING THE GENERATOR

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 insulation 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
windings. Salt (as from sea air) also will worsen the
problem since it tends to absorb moisture from the
air. Salt and moisture, when combined, form a good
electrical conductor.

!
3.8

Do NOT use a forceful spray of water to clean
the generator. Water will enter the generator
interior and cause problems, and may also contaminate the generator fuel system.

BATTERY MAINTENANCE

All lead-acid batteries will discharge when not in use.
The generator battery should be inspected as follows:

◆ 3.8.1 WEEKLY
• Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
• Check the battery fluid level of unsealed batteries
and, if necessary, fill with Distilled Water Only. Do
not use tap water in batteries.

◆ 3.8.2 EVERY SIX MONTHS
• Have the state of charge and condition checked.
This should be done with an automotive-type battery hydrometer.
NOTE:
Servicing of the battery is to be performed or
supervised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries.
Damage will result if the battery connections are
made in reverse.

14 Generac® Power Systems, Inc.

DANGER
Do not dispose of the battery in a fire. The
battery is capable of exploding. Storage batteries give off explosive hydrogen gas. This gas
can form an explosive mixture around the battery for several hours after charging. The
slightest spark can ignite the gas and cause an
explosion. Such an explosion can shatter the
battery and cause blindness or other injury.
Any area that houses a storage battery must be
properly ventilated. Do not allow smoking,
open flame, sparks, or any spark producing
tools or equipment near the battery. Discharge
static electricity from your body before touching the battery by first touching a grounded
metal surface.
A battery presents a risk of electrical shock
and high short circuit current. The following
precautions are to be observed when working
on batteries:
• Remove watches, rings or other metal objects;
• Use tools with insulated handles;
• Wear rubber gloves and boots;
• Do not lay tools or metal parts on top of the
battery;
• Disconnect any charging source prior to connecting
or disconnecting battery terminals; and
• Do not use any jumper cables or booster battery to
crank and start the generator engine. If any battery
has discharged, remove it for recharging.

Do not open or mutilate the battery. Released
electrolyte has been known to be harmful to
the skin and eyes, and to be toxic.
The electrolyte is a dilute sulfuric acid that is
! harmful to the skin and eyes. It is electrically
conductive and corrosive. The following
procedures are to be observed:
• Wear full eye protection and protective clothing;
• Where electrolyte contacts the skin, wash it off
immediately with water;
• Where electrolyte contacts the eyes, flush
thoroughly and immediately with water and seek
medical attention; and
• Spilled electrolyte is to be washed down with an
acid neutralizing agent. A common practice is to
use a solution of 1 pound (500 grams) bicarbonate
of soda to 1 gallon (4 liters) or water. The bicarbonate of soda solution is to be added until the
evidence of reaction (foaming) has ceased. The
resulting liquid is to be flushed with water and the
area dried.

was properly adjusted before the unit was shipped
from the factory. If you suspect that drive belt tension
is incorrect, contact a Generac Authorized Service
Dealer.

3.11 EXERCISING THE GENERATOR
Generac recommends that you start and operate the
generator at least once every seven days. Let
the unit run for at least 30 minutes to “exercise”
the engine.

3.12 OUT OF SERVICE PROCEDURE
◆ 3.12.1 REMOVAL FROM SERVICE
If you cannot exercise the generator every seven days,
and it is to be out of service longer than 30 days, prepare the generator for storage as follows:
1. Start the engine and let it warm up.
2. Close the fuel shutoff valve in the fuel supply line
and allow the unit to shut down.
3. While the engine is still warm from running,
drain the oil completely. Refill the crankcase with
SAE 5W-30 oil having API classification “For
Service SF.”
4. Attach a tag to the engine indicating the viscosity
and classification of the oil in the crankcase.
5. Remove the spark plug and pour two or three
tablespoons of clean, fresh engine oil into the
spark plug threaded openings. Reinstall and
tighten the spark plug.
6. Remove the battery and store it in a cool, dry
room on a wooden board. Never store the battery
on any concrete or earthen floor.
7. Clean and wipe the entire generator.

◆ 3.12.2 RETURN TO SERVICE
To return the unit to service after storage, proceed
as follows:
1. Check the tag on the engine for oil viscosity and
classification. Verify that the correct recommended oil is used in the engine (see Section 1.5.4,
Page 6). If necessary, drain and refill with the
proper oil.

18 Generac® Power Systems, Inc.

! GENERAL HAZARDS !
• For safety reasons, Generac recommends
that the installation, initial start-up and maintenance of this equipment is carried out by a
Generac Authorized Service Dealer.
• The generator engine releases DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death.
Never operate the generator set with the vehicle
inside any garage or other enclosed area. DO NOT
OPERATE THE GENERATOR IF THE EXHAUST
SYSTEM IS LEAKING OR HAS BEEN DAMAGED.
SYMPTOMS OF CARBON MONOXIDE POISONING ARE (a) inability to think coherently, (b) nausea, (c) vomiting, (d) twitching muscles, (e) throbbing temples, (f) dizziness, (g) headaches, (h)
weakness, and (i) sleepiness. IF YOU EXPERIENCE ANY OF THESE SYMPTOMS, MOVE INTO
FRESH AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET MEDICAL HELP. Shut down the generator and do not operate it until it has been inspected and repaired.
• Never sleep in the vehicle while the genset is running unless the vehicle has a working carbon
monoxide detector. The exhaust system must be
installed in accordance with the genset installation
manual. Make sure there is ample fresh air when
operating the genset in a confined area.
• Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts. Never
remove any drive belt or fan guard while the unit is
operating.
• Adequate, unobstructed flow of cooling and ventilating air is critical to correct generator operation
and is required to expel toxic fumes and fuel
vapors from the generator compartment. Without
sufficient cooling airflow, the engine/generator
quickly overheats, which causes serious damage to
the generator. Do not alter the installation or permit even partial blockage of ventilation provisions,
as this can seriously affect safe operation of the
generator.
• When working on this equipment, remain alert at
all times. Never work on the equipment when you
are physically or mentally fatigued.
• Before performing any maintenance on the generator, disconnect its battery cables to prevent accidental start up. Disconnect the cable from the battery post indicated by a NEGATIVE, NEG or (–)
first. Reconnect that cable last.

Safety Rules
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

• Never use the generator or any of its parts as a
step. Stepping on the unit can stress and break
parts, and may result in dangerous operating conditions from leaking exhaust gases, fuel leakage,
oil leakage, etc.
• Never insert any tool or other object through openings in the generator interior, even if the unit is not
running. You might seriously injure yourself or
damage the equipment.

ELECTRICAL HAZARDS
• The generator covered by this manual produces
dangerous electrical voltages and can cause fatal
electrical shock. Avoid contact with bare wires, terminals, 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 mounting 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 “dockside”
power receptacle), there must be no possibility 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 generator is running
may result in damage to the generator or serious
injury or death to dockside (utility) power workers
due to backfeed of electrical energy.
• In case of accident caused by electric shock, immediately 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 implement,
such as a rope or board, to free the victim from the
live conductor. If the victim is unconscious, apply
first aid and get immediate medical help.
• Never wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving components causing injury.

FIRE HAZARDS
• 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 installation, do nothing that might alter a safe installation
and render the unit in noncompliance with the
aforementioned codes, standards, laws and regulations.
• 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 pertaining 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 combustible materials are left in the generator compartment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surrounding 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 governing 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 vehicle 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 pertaining 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 explosion. Do not allow gas vapors to enter the vehicle.

EQUIPMENT DESCRIPTION

Instructions and information in this section pertain
to Generac air-cooled generators. These generators
are designed specifically for installing in recreational
vehicles. They operate 120-volt, single-phase, 60Hertz, AC electrical loads.

5.5

GENERATOR ENGINE
OPERATING SPEED

The generator’s revolving field (rotor) is driven by a
single-cylinder, four-cycle engine through a pulley and
drive belt arrangement. The generator supplies 120
volts AC at 60 Hertz when the rotor is operating at
3,600 rpm.The drive belt arrangement allows the
engine to operate at a lower speed than the rotor.

5.6

GENERATOR AC
CONNECTION SYSTEM

These air-cooled generator sets are equipped with dual
stator AC power windings. These two stator windings
supply electrical power to customer electrical loads by
means of a dual 2-wire connection system.
Generators may be installed to provide the following
outputs:
1) 120 VAC loads only — one load with a maximum
total wattage requirement equal to the generator’s
rated power output (in watts), and 120V across the
generator output terminals. (See Fig. 5.1 below)
2) 120/240 VAC loads — one load with a maximum
total wattage requirement equal to the generator’s
rated power output, and 240 V across the generator
output terminals; or two seperate loads, each with a
maximum total wattage requirement equal to half of
the generator’s rated power output (in watts), and
120 V across the generator output terminals. (See Fig.
5.3 on page 22)

and T3 (Black) to T2 (White), must not exceed ratings for your specific generator (see Section 1.6.3).
NOTE:
Do NOT connect loads in excess of circuit
breaker ratings.

6.1

LOCATION AND SUPPORT

◆ 6.1.1 GENERATOR LOCATION
The most desirable location for the generator set is
between the vehicle's main frame members. However,
this is seldom possible. Most units must be installed
on the side of the vehicle and are difficult to reinforce.
Many recreational vehicles have been factory
equipped with an area for the generator set. Some
vehicles may even have a generator compartment
provided by the vehicle manufacturer.
Plan the generator location based on the following:
• The generator set must be installed on a framework that is part of the recreational vehicle, as outlined in Section 6.1.2.
• The location must provide an access opening that
is large enough to permit generator removal
(unless the generator is to be removed from underneath the supporting framework).
• The location must provide easy access to frequently serviced components, such as filters, oil drains,
spark plugs and other common maintenance
parts.

22 Generac® Power Systems, Inc.

The generator must be securely attached to a metal
framework that has been made part of the vehicle
frame structure by bolting or welding. The metal
framework on which the generator will rest and
which will restrain the generator set should consist of
at least two horizontal beams. These beams should
consist of (a) 1-1/2-inch square, 11-gauge steel tubing
OR (b) 1-1/2-inch, 11-gauge angle iron. A typical supporting frame with horizontal support tubing, is
shown in Figure 6.1.
The generator can be installed so that it sits on top of
the horizontal support tubing if the vehicle design
permits. Another method is to suspend the generator
below the horizontal support tubing by means of suitable, structurally sound metal framework. The following general rules apply:
• Vehicle construction MUST be capable of supporting the weight of the generator.
• Whether the generator is mounted above the horizontal support tubing or suspended below the tubing, the supporting frame used must be structurally sound.
• If the generator cannot be bolted directly to
the supporting frame or support tubing, consider
using additional tubing, angle brackets or other
supports to give the supporting frame sufficient
strength.

Figure 6.1 – Typical Horizontal Support Frame

Section 6 – Installation
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

◆ 6.1.3 SUSPENDED MOUNTING
If you are going to suspend the generator below the
horizontal support tubing, the suspension method
you use with the vehicle frame members must (a) be
able to support the weight of the generator AND (b)
provide sufficient restraint for the generator. One typical suspended mounting system is shown in Figure
6.2. The location of a suspended mounting system
must be carefully planned, keeping the following general rules in mind:
• Protect the generator against road splash and debris.
Baffles or splash guards may be required to protect
certain areas of the generator. To make sure the generator is adequately protected, road test the installation through mud, water and slush.

Figure 6.2 – Typical Suspended Mounting System

6.2

GENERATOR COMPARTMENTS

Whether the generator set is being installed inside a
compartment specifically manufactured to house a generator or inside a compartment that the installer constructs, the compartment MUST meet certain specifications as outlined in the following sections:

◆ 6.2.1 COMPARTMENT SIZE
Plan the compartment size carefully. Provide a minimum clearance of 1/2 inch (13 mm) on the front and
top, 1 inch (25 mm) on the sides, and 1/2 inch (13
mm) from the back for air circulation AFTER the
compartment has been lined with metal and sound
insulation (Figure 6.4).
NOTE:
Refer to “Figure 5.2 – Major Features and
Dimensions” on Page 21.

• The installer must make certain that the selected
location will permit adequate cooling and ventilating airflow to be supplied.

◆ 6.1.4 GENERATOR RESTRAINT
Use four 3/8"-16 hardened steel bolts (Grade 5) to fasten the generator to the supporting frame or the support tubing. These bolts must pass through (a) the generator mounting base, (b) the compartment floor (if a
compartment is used) and (c) the supporting framework (Figure 6.3). All bolts must be long enough so that
when tight, at least three threads are visible past the
retaining lock nuts. Refer to Section 6.2 for the location
of the generator mounting holes.

Figure 6.3 – Typical Generator Restraint

◆ 6.2.2 COMPARTMENT CONSTRUCTION
• The generator compartment should be either constructed of, or lined with, 26-gauge galvanized
steel.
NOTE:
Aluminum is NOT an acceptable alternative
to galvanized steel due to aluminum’s low melting
point.
• If the compartment is lined with galvanized steel, it
may be constructed of any material. Generac recommends that the compartment be constructed of
1/2-inch thick plywood (not strandboard), with the
floor made of a double thickness of 1/2-inch plywood with the grain of the wood at cross section
for added strength (Figure 6.5).

Generac® Power Systems, Inc. 23

Section 6 – Installation
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

Figure 6.5 – Typical Compartment Construction

Figure 6.6 – Types of Lock Seams

• After the compartment has been metal lined and
vapor sealed, line the compartment interior walls
and ceiling with an approved, nonflammable
sound insulating material. See Section 6.2.3.
• If constructing a compartment, line the exterior
(underside) of the compartment floor with 26gauge galvanized steel.
• All seams, splices and joints of the compartment
walls (unless vapor tight by design) should be
caulked to prevent poisonous, flammable or explosive vapors from entering the vehicle interior.
NOTE:
Caulking must be done so that the caulking material will stay in place permanently. Pressing such
materials as putty tape onto joints and seams is
not acceptable. A high quality silicone rubber base
sealant is recommended.
• Holes and openings made in the compartment
walls to allow for the passage of electrical conduit,
conductors, hoses, cables, etc., into the vehicle living area must be sealed vapor tight with silicone
rubber base sealant.
• If flexible metal conduit is used, it must be sealed
internally at the end where it terminates inside the
compartment’s electrical junction box.
NOTE:
Flexible metal conduit, due to its unique construction, is NOT vapor tight along its entire
length.
• Seams and joints of the galvanized steel (whether
used as a liner or for the compartment itself) must
be lapped and mechanically secured. Such seams
may be manufactured, welded, bolted, riveted or
screwed. Manufactured lock seams are shown in
Figure 6.6. Installer constructed compartments
typically utilize a standard lap joint.

24 Generac® Power Systems, Inc.

DANGER
Do not install any flammable material directly
above or around the compartment. Heat,
transferred through the compartment structure,
may be sufficient to ignite, char or discolor
seat cushions, fiberboard and other flammable
materials. You may need to use approved
nonflammable insulating materials in high
temperature areas.

◆ 6.2.3 SOUND INSULATING MATERIALS
Once installers have determined that a compartment
is properly constructed and metal lined, they can add
acoustical material. This may include additional
sealant or insulating material, to reflect noise away
from the vehicle interior.
Sound insulating materials should be of a nonflammable type. One excellent insulating material is a 1inch (25 mm) thick fiberglass having a 2-pound density. When fiberglass is used, its coated side should
face toward the compartment interior.

DANGER
Do not install sound insulation or any
absorbent material on the compartment floor
interior. Such materials will become soaked
with combustible or explosive vapors and liquids and will become a fire hazard.
Using a combination of sound insulating materials
can often reduce noise more effectively than a single
material. For example, a sheet of lead or visco-elastic
material, along with a layer of other acoustical material, is more effective than when a single material is
used.

Section 6 – Installation
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

◆ 6.2.4 ACOUSTICS

◆ 6.2.5 COMPARTMENT FLOOR CUTOUTS

For additional noise abatement, the installer may
wish to consider the following:

You must provide openings in the generator compartment for the following items (Figure 6.8, Page 26):

• Using special sound insulating materials.
• Construction of a special noise abatement compartment.
NOTE:

• Engine exhaust and cooling air outlets
• Generator cooling air inlet
• Four holes for passage of generator mounting
bolts. See Section 6.1.4 (Page 23).

Any method used to reduce noise must not
adversely affect the flow of cooling and ventilating
air into or out of the compartment.

DANGER

In addition to the effective use of sound insulating
materials, construction of a special noise abatement
compartment might be considered to reduce noise
levels. Such a compartment might be constructed as
follows (Figure 6.7):
• Use 5/8-inch thick or 3/4-inch thick plywood in the
compartment.
• Construct the compartment floor of a double thickness of 5/8-inch or 3/4-inch plywood.
• Line the compartment interior walls and floor, as
well as the underside of the floor, with 26-gauge
galvanized steel.
• Vapor seal all compartment seams and joints.
• Over the galvanized steel lining, install a combination of acoustical materials as mentioned in
Section 6.2.3.

DANGER
To prevent fire or explosion, do not install any
insulation or other absorbent materials on the
interior or underside of the compartment floor.
• Seal all compartment door edges to prevent noise
leakage around the door perimeter.
• Line the compartment door interior (except for air
openings) with suitable, fireproof sound insulation
(such as 1-inch (25 mm) thick fiberglass with a 2pound density).

Figure 6.7 – Typical Noise Abatement

Fuel lines and exhaust piping must not pene-

! trate into the vehicle living area.
6.3 COOLING AND VENTILATING AIR
It is absolutely essential that an adequate flow of air
for cooling, ventilating and engine combustion be
supplied to the generator set. Without sufficient airflow, the engine/generator quickly overheats. Such
overheating can cause serious operating difficulties
and also may cause fire and personal injury. The
installer must make sure that sufficient air is available to the generator for cooling, ventilating and combustion. The installer also must provide for a path
for exhausting the cooling air to the exterior of a compartment, if so equipped.

DANGER
Never use discharged cooling air for heating or
permit such air to enter the vehicle interior. This
air contains deadly carbon monoxide gas and
other poisonous, flammable or explosive gases.

◆ 6.3.1 GENERATOR AIRFLOW
Engine operation drives cooling fans for the two-stage
cooling air system. A pressure fan draws cooling air
into the top of the generator (Figure 6.9). This airflow
cools the engine/generator and electronic components. The second part of the cooling system, a suction fan, draws air that is heated from a hot engine
into a collector pan at the base of the unit. This heated air (although cooler than exhaust muffler) is then
deflected out the bottom toward the ground.

sure adequate cooling airflow is available to the unit
before placing the unit into service. If the unit shows
signs of overheating, you will need to enlarge the air
openings. Never place a unit into service until
absolutely certain that cooling and ventilation is adequate.

The installation of a gasoline fuel system (Figure
6.14) for a recreational vehicle generator set must
comply with applicable codes, standards and regulations. The entire fuel system must be completely free
of leaks. There must be no possibility of gasoline
vapors entering the vehicle interior.

inlet. Use a flexible length of approved fuel hose
between the fuel filter inlet connection and rigid fuel
lines.

◆ 6.4.1 FUEL TANK
Either the generator must share the vehicle engine's
fuel tank, or you must install a separate fuel tank for
the generator set. All fuel tanks installed on the vehicle must be constructed, installed and restrained so
they comply with applicable codes, standards and
regulations.
If the generator is to share the vehicle engine's tank,
separate fuel pickup tubes are required for the engine
and the generator. Generac recommends that you
make the fuel pickup tube 2 to 3 inches (51 to 76
mm) shorter than the vehicle engine's pickup tube.
This prevents the generator from depleting the entire
fuel supply during prolonged generator operating
periods.

Do NOT tee the generator fuel supply line into
the vehicle engine fuel supply line. If this is
done, the generator will be starved of fuel
when both engines are operating at the same
time. Also, while the vehicle engine is not running, generator operation may drain the vehicle engine supply line, making it difficult to
start the vehicle engine.

◆ 6.4.2 GENERATOR FUEL SUPPLY LINE

6.4.2.1 Rigid Fuel Lines
Those lines used to supply fuel from a tank to the
generator must comply with applicable codes, standards and regulations. The following general rules
apply to rigid fuel lines:
• Rigid lines should be of annealed, seamless, drawn
aluminum or steel.
• Lines and fittings must comply with SAE J512F,
“Standard Automotive Fittings,” or with ANSI
B126.26 (latest edition).
• Route the fuel line so that at least 2 inches (51 mm)
of clearance is maintained between the line and
any exhaust system parts.
• Do not attach electrical wiring to fuel lines. Route
the wiring so it cannot come into contact with any
fuel line.
• Route fuel lines so if they leak, fuel does not drip
onto any electrical or exhaust system parts.
• Use nonferrous metal straps without sharp edges
to secure fuel lines.

6.4.2.2 Flexible Fuel Line
Use an approved flexible length of fuel hose between
the generator fuel inlet connection and rigid fuel
lines. This prevents breaking of the line caused by
vibration, shifting, settling or movement. The following rules apply:
• The flexible hose must comply with SAE J30B,
“Standard for Fuel and Oil Hose.” It must be
approved for use with gasoline.
• The hose should be at least 6 inches (152 mm)
longer than is needed to prevent the hose from
rupturing if the generator shifts or settles.

6.5

LP GAS FUEL SYSTEM
DANGER

LP gas is highly EXPLOSIVE. The gas is heavier
than air and tends to settle in low areas. Even
the slightest spark can ignite it and cause and
explosion. Only competent, qualified people
should be allowed to install, test, adjust or service an LP gas fuel system. Install the optional
fuel system in compliance with applicable
codes, standards and regulations. After the
installation, do not do anything that might render the system in noncompliance with applicable codes and standards.
The LP powered range of generators are fitted with a
nonadjustable, factory set system. These systems are
tamper-proof to meet 1997 California Air Resources
Board requirements for engine emission.

◆ 6.5.2 PARTS NOT INCLUDED IN FUEL SYSTEM
The propane fuel system does NOT include such
items as (a) gas tank, (b) gas piping, (c) fittings, (d)
valves, and (e) primary regulator, used to store the
gaseous fuel and deliver it to the gaseous fuel solenoid (Figure 2.15, Page 29).

DANGER
Use only approved components in the fuel supply system. All components must be properly
installed in accordance with applicable codes.
Improper installation or use of unauthorized
components may result in fire or an explosion.
Follow approved methods to test the system
for leaks. No leakage is permitted. Do not allow
fuel vapors to enter the vehicle interior.
Generac® Power Systems, Inc. 27

Section 6 – Installation
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

Figure 6.15 – Typical Propane Gas Fuel System

◆ 6.5.5 PRIMARY REGULATOR
Gas pressure delivered to the solenoid valve must be
properly regulated by means of a primary gas regulator. Mount the primary regulator at the gas tank outlet or in the supply line from the gas tank. The following rules apply:
• For best results, the primary regulator supplies
gaseous fuel to the secondary regulator at 11 inches water column. Do NOT exceed 14 inches water
column.
• The installer must be sure the primary regulator is
rated at sufficient gas flow to operate the generator
plus all other gas appliances in the circuit.
NOTE:
Recommended MINIMUM gas flow rate for all aircooled PRIMEPACT series generators is 67 cubic
feet per hour.

◆ 6.5.3 SOME IMPORTANT CONSIDERATIONS
When installing an LP gas system, consider seriously
the following items:
• All fittings, lines, hoses and clamps must be tight
and free of leaks. Apply a pipe sealant to threads
when assembling threaded connections. This
reduces the possibility of leakage.
• Test the entire fuel system for leaks using approved
test methods.
• Optimum gas pressure at the inlet to the gaseous
fuel solenoid valve and secondary regulator is 11
inches water column.
• The installer’s fuel supply connection point is at
the gaseous fuel solenoid valve. This is a 3/4-inch
(female) connection. Provide a suitable 3/4-inch
NPT (male) connector to attach to the fuel supply
line.
• Use a length of approved flexible fuel hose between
the gaseous fuel solenoid valve and rigid gas piping. The flexible line should be at least 6 inches
longer than necessary.

◆ 6.5.4 VAPOR WITHDRAWAL
LP gas is stored in pressure tanks as a liquid. The
gas systems used with these generators were
designed only for vapor withdrawal type systems.
Vapor withdrawal systems use the gas vapors that
form above the liquid fuel in the tank. Do NOT
attempt to use the generator with any liquid withdrawal type system.

28 Generac® Power Systems, Inc.

If an existing primary gas regulator does not have
a sufficient flow capacity for the generator and
other gas appliances in the circuit, (a) install a primary regulator with adequate flow rate, or (b)
install a separate regulator only and rated at least
67 cubic feet per hour. The inlet side of any primary regulator that supplies the generator must
connect directly to a gas pressure tank. Do NOT
tee the generator line into a gas circuit feeding
other areas.

◆ 6.5.6 GASEOUS CARBURETION
LP gas vapors should be supplied to the secondary
regulator inlet at about 11 inches water column (positive pressure). The engine pistons draw air in during
the intake stroke (Figure 6.16). This air passes
through a carburetor venturi, which creates a low
pressure that is proportional to the quantity of air
being pumped. The low pressure from the carburetor
venturi acts on the regulator diaphragm to pull the
diaphragm toward the source of low pressure. A lever
attached to the diaphragm opens a valve to permit
gas glow through the carburetor.

Figure 6.16 – LP Gas Carburetion Diagram

Section 6 – Installation
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

The greater the airflow through the carburetor venturi, the lower the pressure at the venturi throat. The
lower the pressure at the venturi throat, the greater
the diaphragm movement, and the greater the movement of the regulator valve. The more the regulator
valve opens, the greater the gas flow that is proportional to airflow through the generator.
The following facts about the secondary regulator
must be emphasized:
• The regulator must be sensitive to venturi throat
pressure changes throughout the operating range.
• The regulator must be properly adjusted so it will
stop the flow of gas when the engine is not running
(no air flow through the carburetor).
• The slightest airflow (and vacuum in the venturi
throat) should move the regulator valve off its seat
and permit gas to flow.

◆ 6.5.7 FUEL SUPPLY LINES
• LP gas lines must be accessible, but protected
against possible damage.
• Do NOT connect electrical wiring to any LP gas fuel
line or run wiring alongside the lines.
• Route gas lines away from hot engine exhausts.
• Retain gas lines with metal clamps that do not have
sharp edges.
• Install an approved length of flexible hose between
the gaseous fuel solenoid valve and rigid fuel supply lines. The flexible line must be nonmetallic,
nonorganic and nonconductive. It must be
approved for use with LP gas.

◆ 6.5.9 LEAKAGE TESTS
Do not place the generator into service until you have
properly tested the gas system for leaks. To test the
system, you need a separate source of 12 volts DC to
open the gaseous fuel solenoid valve.
The leak test must comply fully with NFPA,
Paragraph 318. All connections, hoses, valve regulators, fittings, and other fuel system parts must be
tested under gas or air pressure of not less than 90
psi (620 kPa), while using soap and water or an
equivalent solution to check for leaks. Other
approved methods of testing for leaks may be used, if
appropriate. DO NOT USE ANY FLAME TO TEST
FOR LEAKS.

6.6

EXHAUST SYSTEM

The generator exhaust system must be safely and
properly installed. Only approved mufflers and other
exhaust system parts must be used. A properly
installed exhaust system must be vapor tight, quiet
and completely safe.

DANGER

The generator engine gives off DEADLY carbon
monoxide gas through its exhaust system. This
dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even
death. Never operate the generator set with
the vehicle inside any garage or other enclosed
area. DO NOT OPERATE THE GENERATOR IF THE
EXHAUST SYSTEM IS LEAKING OR HAS BEEN
DAMAGED. SYMPTOMS OF CARBON MONOXIDE POISONING ARE (a) inability to think coherently; (b) vomiting; (c) twitching muscles; (d)
throbbing temples; (e) dizziness; (f) headaches;
(g) weakness; and (h) sleepiness. IF YOU FEEL
ANY OF THESE SYMPTOMS, MOVE INTO FRESH
AIR IMMEDIATELY. IF SYMPTOMS PERSIST, GET
MEDICAL HELP. Do not operate the generator
until its exhaust system has been inspected and
properly repaired.

Never tee the generator engine exhaust pipe
into the vehicle engine exhaust piping. This
causes excessive back pressure on the generator engine. Also, water from one engine can
damage the other engine.

DANGER
Gaseous fuel lines between the tank and the
secondary regulator are under a positive pressure (about 11 inches water column). Gas pressure at the outlet side of the secondary regulator, however, is a negative pressure and can
draw flame inside a line or fitting and cause an
explosion.

◆ 6.5.8 EXCESS FLOW VALVE
LP gas tanks should have an excess flow valve,
according to NFPA 501C, Paragraph 3-4.4. This valve
and the gas lines must be carefully sized so the valve
will close when a fuel line is severed or broken.
Consult the Natural-LP Gas Association for information and limitations of excess flow valves.
Manual shutoff valves on the supply tank and elsewhere in the system must be fully open when operating the generator. The excess flow valve functions
properly only if all valves are fully open.

◆ 6.6.1 MUFFLERS AND SPARK ARRESTORS
This muffler meets code and standard requirements
of the U.S. Forest Service. Use only mufflers and
parts approved by Generac. Any person(s) installing
an unapproved muffler, or an unapproved exhaust
system part, or modifying an exhaust system in any
way that might cause a hazard, is liable for any damage, injury or warranty expense that might be caused
by such unapproved installation or modification.
Failure to provide and maintain a spark arrestor may
be in violation of the law. If this generator is used on
any forest covered, brush covered or grass covered
unimproved land, you must provide a spark arrestor.
The vehicle owner or operator must maintain this
device in good condition. In the state of California,
the preceding is required by law (Section 4442 of the
California Public Resources Code). Other states may
have similar laws. Federal laws apply on federal
lands.
When installing/replacing the tailpipe or spark
arrestor components, verify that the tailpipe has a
hole to securely fasten the spark arrestor components (see Figure 6.17). Use only Generac supplied
hardware. Substitution of parts may cause damage to
the screen or a loose fit to the tailpipe.

Figure 6.17 — Spark Arrestor Installation

• If there is any possibility of the tailpipe or muffler
being damaged, protect these damage-prone areas
by means of a protective device (such as a skid
bar).
• Install the generator exhaust system according to
safe automotive practices.
• Use enough exhaust system hangers to prevent any
part of the system from being dislocated.
• Use exhaust system parts recommended by
Generac. Using unapproved exhaust mufflers and
exhaust system parts is the responsibility of the
person(s) installing such unauthorized parts.
• Do not terminate the exhaust system under any
opening, window or vent that can be opened or is
not permanently sealed from the vehicle interior.
• Exhaust piping must be large enough to prevent
excessive back pressure on the generator engine.
• Never tee the generator engine exhaust pipe into
the vehicle engine exhaust piping. This causes
excessive back pressure on the generator engine.
Also, water from one engine can damage the other
engine.
• Plan exhaust system installation carefully. Comply
with all applicable codes, standards and regulations.

◆ 6.6.2 EXHAUST SYSTEM SAFETY
• Maintain a clearance of at least 3 inches (76 mm)
between exhaust system parts and any combustible material (such as wood, felt, cotton,
organic fibers or other like material). If you cannot
maintain the 3-inch (76 mm) clearance, locate,
insulate or shield the exhaust part(s) so that the
temperature of any combustible material is not
raised more than 117° F (65° C) above the ambient
air temperature.
• Extend the exhaust system at least 1 inch (25 mm)
past the outer edge of the vehicle. Do not terminate
the exhaust system under the vehicle.
• Terminate the exhaust tailpipe such that exhaust
gases will not be drawn back into the generator
compartment and recirculated.
30 Generac® Power Systems, Inc.

• Qualified electricians who are familiar with applicable codes, standards and regulations should
install electrical wiring.
• The wiring should comply with codes, standards
and regulations. The National Electrical Code
(NFPA 70), and state and local codes apply.
• Switches and circuit breakers should be of a type
approved for use in recreational vehicles and must
be mounted and installed to prevent damage from
road shock.
• Wiring must be of adequate size, have approved
insulative qualities and be properly supported.
• Conduit and wire openings into the generator compartment (if used) must be vapor-sealed to prevent
entry of flammable, explosive or poisonous gases
into the vehicle.

◆ 6.7.1 ELECTRICAL JUNCTION BOX
Install an approved, square electrical junction box
with a blank cover on the interior or exterior wall of
the area you plan to install the generator (NOT on the
generator). Route the generator's AC output leads
into this junction box through approved flexible conduit. This is the point of first termination for generator AC output leads.

Section 6 – Installation
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

◆ 6.7.2 WIRING
• Wiring should be of stranded copper to reduce the
chance that vibration may cause breakage.
• Wire gauge size should be large enough to handle
at least 115 percent of the installed generator's
rated maximum current.
• If neutral conductors are used, they must be the
same size as other leg wires.
• Route power supply conductors from generator AC
output leads T1 (red), T2 (white), T3 (black) and
the green ground wire through approved flexible
conduit to the electrical junction box on the compartment wall.
• If flexible metal conduit is used between the generator and the compartment junction box, the conduit end that terminates the compartment junction
box must be vapor-sealed. Flexible metal conduit
is NOT vapor tight along its entire length.
• From the junction box, route power supply wires
through approved conduit to either (a) doublepole, double-throw transfer switch, or (b)
approved isolation receptacle. Connecting to a
transfer switch or isolation receptacle must prevent vehicle electrical circuits from being connected to two different power supplies at the same time
(such as generator and dockside power).
• Conductors must be rated 221° F (105° C) or must
be of a larger conductor size.

◆ 6.7.3 GENERATOR AC CONNECTIONS
Generator AC output leads T1 (red), T2 (white) and
T3 (black) come out of the generator as shown in
Figure 6.18. Leads T1 (red) and T3 (black) are “hot,”
while T2 (white) is the grounded neutral lead. There
is also a green lead that connects to ground in the
junction box of the recreational vehicle.

Figure 6.18 – Generator AC Output Leads

Line T1 (red) to T2 (white) is protected against overload by a circuit breaker (CB1). Use this line-to-neutral connection separately to operate 120-volt, singlephase, 60 Hertz, AC loads. Line T3 (black) to T2
(white) also is protected against overload by a circuit
breaker (CB2). Use this line-to-neutral connection
separately to operate similar loads. However, be sure
the total unit load does not exceed the maximum rating of the generator. The neutral line (T2, white) on
all units is a grounded neutral.

Do NOT connect electrical loads in excess of
any circuit breaker rating or you will develop
problems with circuit breaker tripping, which
causes a loss of AC output. Also, do NOT
exceed the generator's rated wattage capacity.
Add the watts or amperes of all lighting, appliance, tool and motor loads the generator will
operate at one time. This total should be less
than the unit's rated wattage/amperage capacity.

◆ 6.7.4 CONDUIT
Route the connections between the generator and the
junction box through approved, flexible conduit. The
following general rules apply:
• Cut wiring to the required length and allow extra
wire for junction box connections.
• Carefully prepare conduit ends to prevent sharp
edges from cutting through wiring insulation.
• Route conduit so it does not interfere with generator movement.
• If you use metallic conduit, vapor seal the end of
the conduit where it enters the junction box. Do
this because flexible metallic conduit is not vaporproof along its entire length.

◆ 6.7.5 ISOLATING DIFFERENT POWER

SOURCES

use, you must be certain that both power sources are
NOT connected at the same time.

◆ 6.7.6 POWER SUPPLY CORD
The power supply cord must comply with all applicable codes, standards and regulations. It must be
large enough to handle the full amperage to which it
will be subjected. (See page 33 for illustration.)

BATTERY INSTALLATION

◆ 6.8.1 RECOMMENDED BATTERY
Install a battery that meets the following requirements:
• The battery must be a 12-volt, automotive type
storage battery.
• For prevailing ambient temperatures above 32° F
(0° C), use a battery rated 70 amp-hours and capable of delivering 400 cold-cranking amperes.
• For prevailing ambient temperatures below 32° F
(0° C), use a battery rated 95 amp-hours and capable of delivering 400 cold-cranking amperes.
NOTE:
If the battery is to be used to power other vehicle
accessories, as well as start the generator, you may
need a battery with a larger capacity.

1. Connect the battery cable from the battery post or
terminal indicated by a POSITIVE, POS or (+) to
the lug on the starter contactor (Figure 6.21).
NOTE:
Check to be sure the battery cable boot for the
starter cable has been installed.
2. Connect the battery cable from the battery post
indicated by a NEGATIVE, NEG or (-) to the

7.3

If a liquid propane (LP) gas fuel system has
been installed, it must be properly tested for
leaks before operating the system in compliance with ANSI A119.2/NFPA 501C. No leakage
is permitted. You must be sure no gasoline fuel
vapors enter the vehicle interior.

Do not make any unnecessary adjustments.
Factory settings are correct for most applications. When making adjustments, however, be
careful to avoid overspeeding the engine.

34 Generac® Power Systems, Inc.

1. Turn off all electrical loads. Do this by setting the
generator’s main circuit breakers to their “OFF”
(or open) position.
2. Refer to Part I, Section 2.5, “Starting the
Generator” (Page 8), for cranking and starting
instructions. The engine may require more
cranking for initial starting since the fuel lines
have to be primed (use of the primer switch will
shorten this time).
3. Let the engine warm up for about five minutes to
allow internal temperatures to stabilize.
4. Carefully inspect the engine/generator for fuel, oil
and exhaust system leaks. Before proceeding to
the next step, correct any leakage immediately.
5. When all tests and adjustments at no-load are
completed, apply electrical loads and check for
proper operation under load. See Section 7.4.
Run the unit at least 30 minutes with loads
applied.
6. Turn off all electrical loads by setting the generator’s main circuit breakers to their “OFF” (or

CALIFORNIA AND FEDERAL EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board (CARB) and the United States Environmental Protection Agency (EPA), together with
Generac Power Systems, Inc. (Generac), are pleased to explain the Emission Control System Warranty on your new engine.*
New utility, and lawn and garden equipment engines must be designed, built and equipped to meet stringent anti-smog standards for the state of California and the federal government. Generac will warrant the emission control system on your
engine for the periods of time listed below provided there has been no abuse, neglect, unapproved modification or improper maintenance of your engine.
Your emission control system may include parts such as the carburetor, ignition and exhaust systems. Generac will repair
your engine at no cost to you for diagnosis, replacement parts and labor, should a warrantable condition occur.

MANUFACTURER’S EMISSION CONTROL SYSTEM WARRANTY COVERAGE:
Emissions control systems on 1997 and later model year engines are warranted for two years as hereinafter noted. If, during such warranty period, any emission-related component or system on your engine is found to be defective in materials or
workmanship, repairs or replacement will be performed by a Generac Authorized Warranty Service Facility.

PURCHASER’S/OWNER’S WARRANTY RESPONSIBILITIES:
As the engine purchaser/owner, you are responsible for the completion of all required maintenance as listed in your factory
supplied Owner’s Manual. For warranty purposes, Generac recommends that you retain all receipts covering maintenance
on your engine. However, Generac cannot deny warranty solely because of the lack of receipts or for your failure to ensure
the completion of all scheduled maintenance.
As the engine purchaser/owner, you should, however, be aware that Generac may deny any and/or all warranty coverage or
responsibility if your engine, or a part/component thereof, has failed due to abuse, neglect, improper maintenance or unapproved modifications, or the use of counterfeit and/or ‘grey market’ parts not made, supplied or approved by Generac.
You are responsible for presenting your engine to a Generac Authorized Warranty Service Facility as soon as a problem occurs. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.
Warranty service can be arranged by contacting either your selling dealer or a Generac Authorized Warranty Service Facility.
To locate the Generac Authorized Warranty Service Facility nearest you, call our toll-free number:

1-800-333-1322
IMPORTANT NOTE: This warranty statement explains your rights and obligations under the Emission Control System
Warranty (ECS Warranty), which is provided to you by Generac pursuant to California and federal law. See also the “Generac
Limited Warranties for Generac Power Systems, Inc.,” which is enclosed herewith on a separate sheet, also provided to you
by Generac. The ECS Warranty applies only to the emission control system of your new engine. If there is any conflict in
terms between the ECS Warranty and the Generac Warranty, the ECS Warranty shall apply except in circumstances where
the Generac Warranty may provide a longer warranty period. Both the ECS Warranty and the Generac Warranty describe
important rights and obligations with respect to your new engine.
Warranty service can be performed only by a Generac Authorized Warranty Service Facility. When requesting warranty service, evidence must be presented showing the date of the sale to the original purchaser/owner. The purchaser/owner shall
be responsible for any expenses or other charges incurred for service calls and/or transportation of the product to/from the
inspection or repair facilities. The purchaser/owner also shall be responsible for any and/or all damages or losses incurred
while the engine is being transported/shipped for inspection or warranty repairs.
If you have any questions regarding your warranty rights and responsibilities, you should contact Generac at the following address:

Section 12 – Warranty
QUIETPACT 55, 65, and 75 Recreational Vehicle Generators

EMISSION CONTROL SYSTEM WARRANTY
Emission Control System Warranty (ECS Warranty) for 1997 and later model year engines:
(a) Applicability: This warranty shall apply to 1997 and later model year engines. The ECS Warranty Period shall begin on
the date the new engine or equipment is purchased by/delivered to its original, end-use purchaser/owner and shall continue for 24 consecutive months thereafter.
(b) General Emissions Warranty Coverage: Generac warrants to the original, end-use purchaser/owner of the new engine or
equipment, and to each subsequent purchaser/owner, that each of its engines is ...
(1) Designed, built and equipped so as to conform with all applicable regulations adopted by the EPA and CARB pursuant
to their respective authority, and
(2) Free from defects in materials and workmanship which, at any time during the ECS Warranty Period, may cause a warranted emissions-related part to fail to be identical in all material respects to the part as described in the engine manufacturer’s application for certification.
(c) The ECS Warranty only pertains to emissions-related parts on your engine, as follows:
(1) Any warranted, emissions-related parts that are not scheduled for replacement as required maintenance in the Owner’s
Manual shall be warranted for the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall
be repaired or replaced by Generac according to Subsection (4) below. Any such part repaired or replaced under the ECS
Warranty shall be warranted for the remainder of the ECS Warranty Period.
(2) Any warranted, emissions-related part that is scheduled only for regular inspection as specified in the Owner’s Manual
shall be warranted for the ECS Warranty Period. A statement in such written instructions to the effect of “repair or replace
as necessary” shall not reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS Warranty
shall be warranted for the remainder of the ECS Warranty Period.
(3) Any warranted, emissions-related part that is scheduled for replacement as required maintenance in the Owner’s
Manual shall be warranted for the period of time prior to the first scheduled replacement point for that part. If the part
fails prior to the first scheduled replacement, the part shall be repaired or replaced by Generac according to Subsection
(4) below. Any such emissions-related part repaired or replaced under the ECS Warranty shall be warranted for the
remainder of the ECS Warranty Period prior to the first scheduled replacement point for such emissions-related part.
(4) Repair or replacement of any warranted, emissions-related part under this ECS Warranty shall be performed at no
charge to the owner at a Generac Authorized Warranty Service Facility.
(5) When the engine is inspected by a Generac Authorized Warranty Service Facility, the owner shall not be held responsible for diagnostic costs if the repair is deemed warrantable.
(6) Generac shall be liable for damages to other original engine components or approved modifications proximately caused
by a failure under warranty of any emission-related part covered by the ECS Warranty.
(7) Throughout the ECS Warranty Period, Generac shall maintain a supply of warranted emission-related parts sufficient
to meet the expected demand for such emission-related parts.
(8) Any Generac authorized and approved emission-related replacement part may be used in the performance of any ECS
Warranty maintenance or repairs and will be provided without charge to the purchaser/owner. Such use shall not reduce
Generac’s ECS Warranty obligations.
(9) Unapproved, add-on, modified, counterfeit and/or ‘grey market’ parts may not be used to modify or repair a Generac
engine. Such use voids this ECS Warranty and shall be sufficient grounds for disallowing an ECS Warranty claim.
Generac shall not be held liable hereunder for failures of any warranted parts of a Generac engine caused by the use of
such an unapproved, add-on, modified, counterfeit and/or ‘grey market’ part.

For a period of 3 (three) years or 2,000 (two thousand) hours of operation from the date of original sale, whichever occurs

Generac RV generators manufactured prior to December 31, 1997, DO NOT have a transferable warranty. Generac RV generators manufactured after January 1, 1998, have a transferable warranty to the second owner ONLY for the remainder of
the three-year limited warranty. Proof-of-purchase is required and must be presented to a Generac Authorized Warranty
Service Facility prior to the performance of any warranty service.
All warranty expense allowances are subject to the conditions defined in Generac’s SUPER SERV ICE INFORMATION MANUAL.
THIS WARRANTY SHALL NOT APPLY TO THE FOLLOWING:
• Generac Guardian generators that utilize non-Generac replacement parts.
• Costs of normal maintenance, adjustments, installation and start-up.
• Failures caused by any contaminated fuels, oils, coolants or lack of proper fluid amounts.
• Failures due, but not limited, to normal wear and tear, accident, misuse, abuse, negligence or improper installation. As with
all mechanical devices, the Generac engines need periodic part(s) service and replacement to perform well. This warranty
will not cover repair when normal use has exhausted the life of a part(s) or engine.
• Failures caused by any external cause or act of God, such as collision, theft, vandalism, riot or wars, nuclear holocaust, fire,
freezing, lightning, earthquake, windstorm, hail, volcanic eruption, water or flood, tornado or hurricane.
• Damage related to rodent infestation.
• Products that are modified or altered in a manner not authorized by Generac in writing.
• Any incidental, consequential or indirect damages caused by defects in materials or workmanship, or any delay in repair or
replacement of the defective part(s).

THIS WARRANTY IS IN PLACE OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED. SPECIFICALLY, GENERAC MAKES
NO OTHER WARRANTIES AS TO THE MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Some states do not
allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.
GENERAC'S ONLY LIABILITY SHALL BE THE REPAIR OR REPLACEMENT OF PART(S) AS STATED ABOVE. IN NO EVENT
SHALL GENERAC BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES, EVEN IF SUCH DAMAGES ARE A
DIRECT RESULT OF GENERAC'S NEGLIGENCE. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation may not apply to you.
This warranty gives you specific legal rights. You also have other rights from state to state.
