! GENERAL HAZARDS !
• For safety reasons, the manufacturer recommends
that this equipment be installed, serviced and
repaired by an Authorized Service Dealer or other
competent, qualified electrician or installation technician who is familiar with applicable codes, standards
and regulations. The operator also must comply with
all such codes, standards and regulations.
• Installation, operation, servicing and repair of this
(and related) equipment must always 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, operated and serviced in accordance
with the manufacturer’s instructions and recommendations. Following installation, do nothing that might
render the unit unsafe or in noncompliance with the
aforementioned codes, standards, laws and regulations.
• The engine exhaust fumes contain carbon monoxide
gas, which can be DEADLY. This dangerous gas, if
breathed in sufficient concentrations, can cause
unconsciousness or even death. For that reason, adequate ventilation must be provided. Exhaust gases
must be piped safely away from any building or
enclosure that houses the generator to an area where
people, animals, etc., will not be harmed. This
exhaust system must be installed properly, in strict
compliance with applicable codes and standards.
• 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 prevent buildup of explosive gases
and to ensure correct generator operation. Do not
alter the installation or permit even partial blockage
of ventilation provisions, as this can seriously affect
safe operation of the generator.
• Keep the area around the generator clean and uncluttered. Remove any materials that could become hazardous.
• When working on this equipment, remain alert at all
times. Never work on the equipment when physically
or mentally fatigued.
Important Safety Instructions
Liquid-cooled 15 kW, 20 kW and 25 kW Generators
• Inspect the generator regularly, and promptly repair
or replace all worn, damaged or defective parts using
only factory-approved parts.
• 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
• All generators covered by this manual produce dangerous electrical voltages and can cause fatal electrical
shock. Utility power delivers extremely high and dangerous voltages to the transfer switch as well as the
standby generator. Avoid contact with bare wires, terminals, connections, etc., on the generator as well as
the transfer switch, if applicable. Ensure all appropriate covers, guards and barriers are in place before
operating the generator. If work must be done 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.
• If people must stand on metal or concrete while
installing, operating, servicing, adjusting or repairing
this equipment, place insulative mats over a dry
wooden platform. Work on the equipment only while
standing on such insulative mats.
• The National Electrical Code (NEC), Article 250
requires the frame and external electrically conductive parts of the generator to be connected to an
approved earth ground and/or grounding rods. This
grounding will help prevent dangerous electrical
shock that might be caused by a ground fault condition in the generator set or by static electricity. Never
disconnect the ground wire.
• Wire gauge sizes of electrical wiring, cables and cord
sets must be adequate to handle the maximum electrical current (ampacity) to which they will be subjected.
• Before installing or servicing this (and related) equipment, make sure that all power voltage supplies are
positively turned off at their source. Failure to do so
will result in hazardous and possibly fatal electrical
shock.
• Connecting this unit to an electrical system normally
supplied by an electric utility shall be by means of a
transfer switch so as to isolate the generator electric
system from the electric utility distribution system
when the generator is operating. Failure to isolate the
two electric system power sources from each other by
such means will result in damage to the generator
and may also result in injury or death to utility power
workers due to backfeed of electrical energy.
• Generators installed with an automatic transfer
switch will crank and start automatically when normal (utility) source voltage is removed or is below an
acceptable preset level. To prevent such automatic
start-up and possible injury to personnel, disable the
generator’s automatic start circuit (battery cables,
etc.) before working on or around the unit. Then,
place a “Do Not Operate” tag on the generator control
panel and on the transfer switch.
• 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 dry 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
• Keep a fire extinguisher near the generator at all
times. Do NOT use any carbon tetra-chloride type
extinguisher. Its fumes are toxic, and the liquid can
deteriorate wiring insulation. Keep the extinguisher
properly charged and be familiar with its use. If there
are any questions pertaining to fire extinguishers,
consult the local fire department.
EXPLOSION HAZARDS
• Properly ventilate any room or building housing the
generator to prevent build-up of explosive gas.
• 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.
• This generator set may operate using one of several
types of fuels. All fuel types are potentially FLAMMABLE and/or EXPLOSIVE and should be handled with
care. Comply with all laws regulating the storage and
handling of fuels. Inspect the unit’s fuel system frequently and correct any leaks immediately. Fuel supply lines must be properly installed, purged and leak
tested according to applicable fuel-gas codes before
placing this equipment into service.
• Diesel fuels are highly FLAMMABLE. Gaseous fluids
such as natural gas and liquid propane (LP) gas are
extremely EXPLOSIVE. Natural gas is lighter than air,
and LP gas is heavier than air; install leak detectors
accordingly.

1.3
AUTOMATIC SYSTEM OPERATION
This equipment is a liquid-cooled, engine-driven generator set. The generator is designed to supply electrical power that operates critical electrical loads
during utility power failure. The unit has been factory-installed in a weather resistant, all metal enclosure
and is intended for outdoor installation only. Use this
generator as a source of electrical power for the operation of 120 and/or 240 volts, single phase loads.
When this generator, along with its transfer switch, has
been installed and interconnected, a circuit board in
the generator panel constantly monitors utility power
source voltage. Should that voltage drop below a preset value, and remain at such a low state for a preset
amount of time, the generator cranks and starts. After
the generator starts, the transfer switch transfers load
circuits so the generator can power them.
These models are available. They are rated as follows:
When utility source voltage has been restored, the
switch re-transfers back to the utility source voltage
and the generator then shuts down.
Model 004742-0: Provides 15,000 watts (15 kW) of 1 phase power.
Model 004744-0: Provides 20,000 watts (20 kW) of 1 phase power.
Model 004746-0: Provides 25,000 watts (25 kW) of 1 phase power.
!
1.2
If this generator is used to power electrical load
circuits normally powered by a utility power
source, it is required by code to install a transfer switch. The transfer switch must effectively
isolate the electric system from the utility distribution system when the generator is operating
(NEC 701). Failure to isolate an electrical system
by such means results in damage to the generator and may also result in injury or even death
to utility power workers due to backfeed of
electrical energy.
TRANSFER SWITCH
Please reference the transfer switch manual for specific information.
1.4
GENERATOR AC CONNECTION
SYSTEMS
The generator was shipped from the factory with its
stator AC output leads connected in a single-phase,
3-wire generator AC connection system (Figure 1.1).
The stator assembly in this system consists of a pair
of stationary windings, with two leads brought out of
each winding. Each single winding can supply 120
volts AC, 60 Hertz. When the two windings are connected in series, a 240 volts, 60 Hertz AC output
results. Typically the two “hot” leads in the circuit are
Wires No. 11 and 44. The “Neutral” leads are the
junction of Wires 22 and 33.
Figure 1.1 - Generator AC Connection System
This generator system may include a matched automatic transfer switch which is intended to be used in
conjunction with the generator. It is supplied in either
a NEMA 1 enclosure or a NEMA 3R enclosure. The
NEMA 1 enclosure is intended for indoor use only.
The NEMA 3R enclosure is weather proof and can be
used indoors or outdoors. Follow these rules:
• Install the transfer switch on a firm, sturdy supporting structure.
• To prevent switch distortion, level the switch if necessary. This can be done by placing washers
between the switch enclosure and the mounting
surface.
• Never install the switch where water or any corrosive substance might drip onto the enclosure.
• Protect the switch at all times against excessive
moisture, dust, dirt, lint, construction grit and corrosive vapors.
If a transfer switch is not included, one may be purchased separately from an Authorized Dealer.
1.5
MAIN CIRCUIT BREAKER
The generator’s main circuit breaker is included with
the unit as shipped from the factory. The breaker for
each unit is described in Figure 1.2 at the top of page
5.
1.6
GENERATOR FUEL SYSTEM
This unit has been factory tested and adjusted using
a natural gas fuel system. If propane (LP) gas is preferred, contact an authorized service dealer.

* Amp Rating of C/B structured
Gaseous fuels such as natural and LP (propane)
gas are highly explosive. Even the slightest
spark can ignite such fuels and cause an explosion. No leakage of fuel is permitted. Natural
gas, which is lighter than air, tends to collect in
high areas. LP gas is heavier than air and tends
to settle in low areas.
ENGINE PROTECTIVE DEVICES
The engine has several safety switches which cause
the engine to automatically shut down under the following conditions: low oil pressure, high coolant temperature, engine overspeed, low coolant level or overcrank (Figure 1.3).

LOW OIL PRESSURE SWITCH
This switch is normally-closed (N.C.) but is held open
by engine oil pressure during engine running. Should
operating oil pressure drop below about 8-10 psi
(55-68 kPa), the switch contacts close and the engine
shuts down automatically (Figure 1.4).
Figure 1.4 - Low Oil Pressure Switch
‹ 1.7.2 HIGH COOLANT TEMPERATURE SWITCH
Normally open (N.O.) thermostatic switch has sensing tip which is immersed in captive coolant. Should
coolant temperature exceed about 230°F (110°C), the
switch contacts close, which causes the engine to
shut down automatically (Figure 1.5).
Figure 1.5- High Coolant Temperature Switch
‹ 1.7.3
LOW COOLANT LEVEL SWITCH
Should engine coolant level drop below the level of
the high coolant temperature switch, it is possible for
the engine to overheat without automatic shutdown.
To prevent such overheating without automatic shut
down, the engine has a low coolant level sensor. If the
engine coolant drops too low, the engine automatically shuts down (Figure 1.6 on page 6).

‹ 1.7.7
‹ 1.7.4
OVERSPEED SHUTDOWN
The pre-pack circuit board on liquid cooled units
receives AC frequency (rpm) signals directly from the
stator AC power windings, via sensing leads S15 and
S16. Should AC frequency exceed about 72 Hz, circuit board action will automatically shutdown the
engine (Figure 1.7).
*Rated power of generator is subject to and limited by such factors as ambient temperature, altitude, engine condition, and other factors. Engine
power will decrease about 3.5% for each 1000 feet
above sea level and will decrease an additional 1%
for each 10°F above 60°F. Maximum output power
of the generator is limited by maximum engine
power.

1.16 BEFORE INSTALLATION
Before installing this equipment, check the ratings of
both the generator and the transfer switch. Read
“Emergency Isolation Method” and “Total Circuit
Isolation Method” in the installation manual (Part No.
079699).
The generator’s rated wattage/amperage capacity
must be adequate to handle all electrical loads that
the unit will power. Group the critical (essential)
loads together and wire them into a separate “emergency” distribution panel.
This generator can be installed in conjunction with a
standard “GTS” type transfer switch, if desired.
The standard transfer switch has no sensing or controlling circuit boards. Instead, the generator control
console houses a “Printed Circuit Board Assembly”,
which controls all phases of operation, including
engine start up and load transfer.
2.1
!
Any attempt to crank or start the engine before
it has been properly serviced with the recommended oil may result in an engine failure.
1.15 COOLANT RECOMMENDATIONS
Use a mixture of half low silicate ethylene glycol base
anti-freeze and half soft water. Cooling system capacity is about 8 U.S. quarts (7.6 liters). Use only soft
water and only low silicate anti-freeze. If desired, add
a high quality rust inhibitor to the recommended
coolant mixture. When adding coolant, always add
the recommended 50-50 mixture.
!
Do not use any chromate base rust inhibitor
with ethylene glycol base anti-freeze or chromiumhydroxide (“green slime”) forms and will
cause overheating. Engines that have been
operated with a chromate base rust inhibitor
must be chemically cleaned before adding ethylene glycol base anti-freeze. Using any high silicate anti-freeze boosters or additives will also
cause overheating. DO NOT use any soluble oil
inhibitor for this equipment.
STANDBY GENERATOR
INSTALLATION
DANGER
Connecting this generator to an electrical system
normally supplied by an electric utility shall be by
means of a transfer switch, so as to isolate the
electric system from the utility distribution system when the generator is operating. Failure to
isolate the electric system by these means will
result in damage to the generator and may also
result in injury or death to utility workers due to
backfeed of electrical energy.
If an open bottom is used, the engine-generator is to be installed over non-combustible
materials and should be located such that combustible materials are not capable of accumulating under the generator set.
Only qualified, competent installation contractors or
electricians thoroughly familiar with applicable
codes, standards and regulations should install this
standby electric power system. The installation must
comply strictly with all codes, standards and regulations pertaining to the installation.
After the system has been installed, do nothing
that might render the installation in noncompliance with such codes, standards and regulations.

2.2
GENERATOR LOCATION
Install the generator set, in its protective enclosure
outdoors, where adequate cooling and ventilating air
always is available. Consider these factors:
• Install the generator as close as possible to the
transfer switch. This reduces the length of wiring
and conduit.
• Install the generator as close as possible to the fuel
supply, to reduce the length of piping. HOWEVER,
REMEMBER THAT LAWS OR CODES MAY REGULATE THE DISTANCE.
2.3
GENERATOR MOUNTING AND
SUPPORT
Retain the generator compartment to a concrete slab
with 1/4-inch masonry type anchor bolts. Be sure the
bolts are long enough to retain the compartment. The
slab should be at least 6 inches thick and should
extend beyond the enclosure to a distance of at least
3 inches on all sides. See pages 54-55 for generator
major dimensions.
2.4
BASIC STANDBY ELECTRIC
SYSTEM
Figure 2.1 shows a schematic diagram of a basic
standby electric system. Both the UTILITY power
supply and the STANDBY (generator) output are connected to an approved transfer switch. The transfer
switch is required by electrical code and serves the
following functions:
• Permits the LOAD circuits to be connected to only
one power supply at a time.
• Prevents electrical backfeed between the generator
and the UTILITY power circuits.
Notice that both the STANDBY and the UTILITY
power supplies to the transfer switch are protected
against overload by a main line circuit breaker.
NOTE:
The manufacturer recommends the use of a “GTS”
type transfer switch in conjunction with this generator.
Figure 2.1 – Basic Standby Electric System
• Install the unit where air inlet and outlet openings
will not become obstructed by leaves, grass, snow,
etc. If prevailing winds will cause blowing or drifting, consider using a windbreak to protect the unit.
• Install the generator on high ground where water
levels will not rise and endanger it.
• Allow sufficient room on all sides of the generator
for maintenance and servicing. A good rule is to
allow 5 feet of space on all sides.
• Where strong prevailing winds blow from one
direction, face the generator air inlet openings into
the prevailing winds.

2.5
EMERGENCY CIRCUIT ISOLATION
METHOD
This prevents overloading the generator by keeping
electrical loads below the wattage/amperage capacity
of the generator. If the generator is powering only critical loads, within the wattage/amperage capacity, during utility power outages, consider using the emergency circuit isolation method.
Proper grounding helps protect personnel against
electrical shock in the event of a ground fault condition in the generator or in connected electrical
devices. In addition, grounding helps dissipate static
electricity that often builds up in ungrounded
devices.
Figure 2.2 – Generator Grounding Lug (typical)
Critical electrical loads are grouped together and
wired into a separate “Emergency Distribution
Panel.” Load circuits powered by that panel are within the wattage/amperage capacity of the generator set.
When this method is used, it is difficult to overload
the generator. The transfer switch must meet the following requirements:
• It must have an ampere rating equal to the total
amperage rating of the emergency distribution
panel circuit.
• Have it installed between the building’s main distribution panel and the emergency distribution
panel.
2.6
TOTAL CIRCUIT ISOLATION
METHOD
When a generator capable of powering all electrical
loads in the circuit is to be installed, use the “Total
Circuit Isolation Method.” It is possible for the generator to be overloaded when this isolation method is
employed. The following apply to the transfer switch
in this type of system.
2.8
GENERATOR AC NEUTRAL
CONNECTIONS
• Ampere rating of the transfer switch must equal
the ampere rating of the normal incoming utility
service.
• The transfer switch is installed between the utility
service entrance and the building distribution
panel.
The manufacturer uses an UNGROUNDED AC neutral. Grounding is recommended only at the main
service entrance. If the neutral wire is grounded and
one of the phase loads becomes grounded, the excessive current opens the load circuit breaker or collapses the generator field. The actual result depends
on the electrical characteristics of the particular
installed generator.
2.7
2.9
GROUNDING THE GENERATOR
The National Electrical Code requires the frame and
external electrically conductive parts of this equipment to be properly connected to an approved earth
ground and/or grounding rods. For that purpose, a
GROUND LUG (Figure 2.2) is provided on the generator mounting base. Consult a qualified electrician
for grounding requirements in the area. Grounding
procedures must meet local regulations.
DANGER
Do not connect the ground wire to any pipe
that carries a flammable or explosive substance
– FIRE or an EXPLOSION may result.
10
TRANSFER SWITCH START SIGNAL
CONNECTIONS
If the generator is to be installed with an automatic
transfer switch, such as a GTS-type switch, it will be
necessary to connect the two-wire start control system.
Connect the two-wire start signal from the automatic
transfer switch to the automatic start connection,
which is located in the right hand corner inside the
control panel. Match wires 178 and 183 in the transfer switch to 178 and 183 on the terminal strip in the
control panel. The conductors for the two-wire start
circuit must be in their own conduit.
Section 2 — Installation
Liquid-cooled 15 kW, 20 kW and 25 kW Generators
2.10 BATTERY INSTALLATION
DANGER
!
Standby generators installed with automatic
transfer switches will crank and start automatically when normal (utility) source voltage is
removed or is below an acceptable preset level.
To prevent such automatic start-up and possible
injury to personnel, do not connect battery
cables until certain that normal source voltage
at the transfer switch is correct and the system
is ready for operation.
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.
!
!
Battery electrolyte fluid is an extremely caustic
sulfuric acid solution that can cause severe
burns. Do not permit fluid to contact eyes, skin,
clothing, painted surfaces, etc. Wear protective
goggles, protective clothing and gloves when
handling a battery. If fluid is spilled, flush the
affected area immediately with clear water.
Do not dispose of the battery in a fire. The battery is capable of exploding.
Do not open or mutilate the battery. Released
electrolyte can be toxic and harmful to the skin
and eyes.
The battery represents a risk of high short circuit current. When working on the battery,
always remove watches, rings or other metal
objects, and only use tools that have insulated
handles.
‹ 2.10.1 VENTED BATTERIES
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 one pound (500 grams) bicarbonate of soda to one gallon (4 liters) of 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.
Lead acid batteries present a risk of fire
because they generate hydrogen gas. The following procedure are to be followed:
• DO NOT SMOKE when near batteries,
• DO NOT cause flame or spark in battery area, and
• Discharge static electricity from body before touching batteries by first touching a grounded metal
surface.
Servicing of batteries is to be performed or supervised by personnel knowledgeable of batteries and
the required precautions. Keep unauthorized personnel away from batteries.
For recommended batteries, see “Specifications.” All
batteries must be at 100 percent state-of-charge
before they are installed on the generator.
When using maintenance-free batteries, it is not necessary to check the specific gravity or electrolyte level.
Have these procedures performed at the intervals
specified in Section 4, “Maintenance.” A negative
ground system is used. Battery connections are
shown on the wiring diagrams. Make sure all batteries are correctly connected and terminals are tight.
Observe battery polarity when connecting batteries
to the generator set.
NOTE:
Damage will result if the battery connections are
made in reverse.
2.11 PREPARATION BEFORE START-UP
The instructions in this section assume that the standby generator has been properly installed, serviced,
tested, adjusted and otherwise prepared for use by a
competent, qualified installation contractor. Be sure to
read the “Safety Rules” on Pages 2 and 3, as well as all
other safety information in this manual, before
attempting to operate this (and related) equipment.
‹ 2.11.1 PRIOR TO INITIAL START-UP
Prior to initially starting the generator, it must
be properly prepared for use. Any attempt to
crank or start the engine before it has been
properly serviced with the recommended types
and quantities of engine fluids (oil, coolant,
fuel, etc.) may result in an engine failure.
Before starting the generator for the first time, the
installer must complete the following procedures. For
follow-up maintenance information and/or service
intervals, please refer to Section 4, “Maintenance.”

Liquid-cooled 15 kW, 20 kW and 25 kW Generators
‹ 2.11.2 TRANSFER SWITCH
If this generator is used to supply power to any electrical system normally powered by an electric utility,
the National Electrical Code requires that a transfer
switch be installed. The transfer switch prevents electrical backfeed between two different electrical systems. (For additional information, see the applicable
transfer switch manual for this unit.) The transfer
switch, as well as the generator and other standby
components, must be properly located and mounted
in strict compliance with applicable codes, standards
and regulations.
‹ 2.11.3 FUEL SYSTEM
Make sure the fuel supply system to the generator (a)
delivers the correct fuel at the correct pressure and
(b) is properly purged and leak tested according to
code. No fuel leakage is permitted. See
“Specifications” (Page 7) for more information.
‹ 2.11.4 GENERATOR SET LUBRICATION
Check the engine crankcase oil level before operating
and add oil to the proper level – the dipstick “FULL”
mark. Never operate the engine with the oil level
below the dipstick “ADD” mark. See “Specifications”
(Page 7) and “Engine Oil Recommendations” (Page 8).
NOTE:
This engine is shipped from the manufacturer
with 15W-40 oil. This oil should be changed after
30 hours of operation.
‹ 2.11.5 ENGINE COOLANT
Have the engine cooling system properly filled with
the recommended coolant mixture. Check the system
for leaks and other problems. See “Specifications”
and “Coolant” (Page 7).
‹ 2.11.6 BELT TENSION
Check the engine fan belt tension and condition prior
to placing the unit into service and at recommended
intervals. Belt tension is correct when a force of
approximately 22 pounds (10 kg), applied midway
between pulleys, deflects the belt about 3/8- to 5/8inch (10 to 16 mm).
‹ 2.11.7 ELECTRICAL SYSTEM
Make sure the generator is properly connected to an
approved earth ground and/or ground rod.
3.1
USING A STANDARD “GTS”
TRANSFER SWITCH
When required, the pre-packaged standby generator
can be installed with a standard “GTS” type automatic transfer switch.
When using a standard GTS type transfer switch, it
controls automatic operation and automatic transfer
as follows:
• Solid state circuits in the transfer switch monitor
utility power source voltage.
• When utility source voltage drops below a pre-set
level, transfer switch action closes the circuit. The
engine then cranks and starts as controlled by the
pre-packaged generator’s Control Module circuit
board.
• After the engine starts and when the generator AC
output voltage and frequency have reached a
pre-set value, transfer switch circuits signal the
transfer switch main contacts to actuate to the
“Standby” power source side. Generator AC output
then powers load circuits.
• When the utility power source voltage is restored
above a pre-set level, transfer switch solid state
circuits signal the switch main contacts to move
back to their utility power source side.
• Following re-transfer back to the utility power
source side, transfer switch circuit board action
opens the circuit. Engine then shuts down.
NOTE:
If the generator is installed in conjunction with a
standard GTS type transfer switch, refer to the
applicable transfer switch manual for exact operating parameters and timing sequences.

‹ 4.5.7
DANGER
!
Do not attempt to adjust the governor. Only
qualified service facilities should adjust the
governor. Excessively high operating speeds are
dangerous and increase the risk of personal
injury. Low speeds impose a heavy load on the
engine when adequate engine power is not
available and may shorten engine life. Correct
rated frequency and voltage are supplied only
at the proper governed speed. Some connected
electrical load devices may be damaged by
incorrect frequency and/or voltage. Only qualified service technicians should adjust the governed speed.
‹ 4.5.10 CHANGING ENGINE OIL
Refer to maintenance performed by authorized service facilities for engine oil and filter change frequencies.
Drain the oil while the engine is still warm from running. This means warm up the engine, shut it down
and drain immediately as follows:
1. Remove OIL DRAIN HOSE from its retaining clip.
2. Loosen and remove OIL DRAIN HOSE CAP.
Drain oil completely into suitable container.
3. When all oil has drained, install and tighten OIL
DRAIN HOSE CAP, and re-install into its retaining
clip.
4. Turn OIL FILTER (Figure 4.2) counterclockwise
and remove. Dispose of old filter.

4.6
MISCELLANEOUS MAINTENANCE
‹ 4.6.1
CLEANING THE GENERATOR
Keep the generator as clean and as dry as possible.
Dirt and moisture that accumulates on internal generator windings have an adverse effect on insulation
resistance.
(Doors Removed for Clarity)
See the “Service Schedule,” Section 6, for air cleaner
maintenance.
‹ 4.5.12 SPARK PLUGS
Reset the spark plug gap or replace the spark plugs
as necessary. See Section 6.
1. Clean the area around the base of the spark plugs
to keep dirt and debris out of the engine. Clean by
scraping or washing using a wire brush and commercial solvent. Do not blast the spark plugs to
clean.
2. Remove the spark plugs and check the condition.
Replace the spark plugs if worn or if reuse is
questionable. See the “Service Schedule,” Section
6, for recommended inspection.
3. Check the spark plug gap using a wire feeler
gauge. Adjust the gap to 0.5-0.6 mm (0.020-0.025
inch) by carefully bending the ground electrode
(Figure 4.4).
Periodically clean generator exterior surfaces. A soft
brush may be used to loosen caked on dirt. Use a
vacuum system or dry, low pressure air to remove
any accumulations of dirt. The generator is housed
inside an all-weather enclosure, clean the enclosure
with a soft, damp cloth or sponge and water.
Once each year have the generator cleaned and
inspected by an Authorized Service Dealer. That dealer will use dry, low pressure air to clean internal
windings. Parts inside the control console should be
cleaned and inspected at this time as well.
Finally, have the insulation resistance of stator and
rotor windings checked. If insulation resistances are
excessively low, the generator may require drying.
‹ 4.6.2
BATTERY
All lead-acid storage batteries discharge when not in
use. Refer to specific instructions and warnings that
accompany the battery. If such information is not
available, observe the following precautions when
handling a battery:
• DO NOT use jumper cables and a booster battery
to crank or start the generator engine.
• DO NOT recharge a weak battery while it is
installed in the generator. Remove battery from
generator and recharge in a well-ventilated area,
away from fuel vapors, sparks, heat or flames.
• Battery electrolyte fluid is an extremely caustic
17
Section 4 — Maintenance
Liquid-cooled 15 kW, 20 kW and 25 kW Generators
sulfuric solution that can cause severe burns. DO
NOT permit fluid to contact eyes, skin, clothing,
painted surfaces, wiring insulation, etc. If any battery fluid is spilled, flush the affected area with
clear water immediately.
• Always wear safety glasses, rubber apron and
gloves when handling a battery.
• Batteries give off explosive hydrogen gas while
charging. The gas can form an explosive mixture
around the battery for several hours after charging.
Any spark, heat or flames can ignite the gas and
cause an explosion which can shatter the battery,
causing blindness or other serious injury.
‹ 4.6.4
‹ 4.6.3
When replacing batteries, use the same number and
the type of battery that follows:
BATTERY MAINTENANCE
The battery should be inspected per the “Service
Schedule,” Section 6. The following procedure
should be followed for inspection:
1. Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
2. Check the battery fluid level of unsealed batteries
and, if necessary, fill with DISTILLED WATER
ONLY. DO NOT USE TAP WATER IN BATTERIES.
3. Have the state of charge and condition checked.
This should be done with an automotive-type battery hydrometer.
DANGER
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.
!
Battery electrolyte fluid is an extremely caustic
sulfuric acid solution that can cause severe
burns. Do not permit fluid to contact eyes, skin,
clothing, painted surfaces, etc. Wear protective
goggles, protective clothing and gloves when
handling a battery. If fluid is spilled, flush the
affected area immediately with clear water.
!
Do not use any jumper cables or booster battery to crank and start the generator engine. If
the battery has completely discharged, remove
it from the generator for recharging.
18
!
Be sure the Auto/Off/Manual switch is set to
the OFF position before connecting the battery
cables. If the switch is set to AUTO or MANUAL,
the generator can crank and start as soon as
the battery cables are connected.
Be sure the utility power supply is turned off,
or sparking may occur at the battery posts as
the cables are attached and cause an explosion.

CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board (CARB) and Generac Power Systems, Inc. (Generac) are pleased to explain the Emission
Control System Warranty on your new engine.* In California, new utility, and lawn and garden equipment engines must be
designed, built and equipped to meet the state’s stringent anti-smog standards. 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 system and exhaust system. 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 1995 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 due to 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 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.
If you have any questions regarding your warranty rights and responsibilities, you should contact Generac at the following address:

Section 10 – Warranty
Liquid-cooled 15 kW, 20 kW and 25 kW Generators
EMISSION CONTROL SYSTEM WARRANTY
Emission Control System Warranty (ECS Warranty) for 1995 and later model year engines:
(a) Applicability: This warranty shall apply to 1995 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 CARB pursuant to its
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 owner. Such use shall not reduce Generac
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.
