INTRODUCTION
INTENDED USES
The EC18000VE engine generator set has been designed primarily
for heavy duty commercial use. A 240 volt receptacle is provided in
the control panel to plug in your loads. The EC22000VE is hard-wire
connectible only. These units are dual wound generators, therefore
the 120 volt loads must be equally split with 1/2 of the rated capacity
available on each of the two 120 volt circuits.
These units require large quantities of fresh air for cooling the engine
and generator. For safety, long life and adequate performance, these
units should never be run in small compartments without positive fresh
air ow.
RESTRICTED USES
DO NOT install and operate this generator in a small compartment.,
i.e. generator compartments of vehicles, motor homes or travel
trailers. These compartments will not allow enough free ow of fresh
air to reach the engine generator set for cooling and will cause the
unit to overheat, damaging both the engine and generator. Small
compartments will also develop hot spots where there is very little air
ow and may cause a re.
PLEASE NOTE There are 3rd party companies making enclosures for
generators that have been properly engineered. The use of these 3rd
party enclosures is acceptable as long as they have been certied and
meet current code.
DO NOT attempt to operate at 50 cycles. These units are designed and
governed to operate at 60 cycles only.
UNIT CAPABILITIES
GENERATOR CONNECTIONS
The diagram below represents this 15,000 watt (rated output)
generator. A & B represent the 120 volt output legs of this generator.
Up to 7500 watts at 120 volts (45 Amps) can be drawn from the
receptacles attached to either A or B output legs. This generator is
capable of producing 62.5 Amps of 240 volt current at C. Check the
appliance or tool nameplates for the current and voltage to insure
compatibility. Remember that power taken from C reduces the power
available at equally both A and B and vice versa.
Check the appliance or tool nameplates for the current and voltage
to ensure compatibility. Remember tha power utilized from C reduces
the power available from both A and B and vice versa. The EC22000
utilizes the same format with A and B being 9500 Watts and C being
19,000 Watts.
STARTING ELECTRIC MOTORS
Electric motors require much more current (amps) to start them than to
run them. Some motors, particularly low cost split-phase motors, are
very hard to start and require 5 to 7 times as much starting current as
running current. Capacitor motors are easier to start and usually require
2 to 4 times as much starting current as running current. Repulsion
Induction motors are the easiest to start and require only 1 1/2 to 2 1/2
times as much starting as running current.
Most fractional horsepower motors take about the same amount
of current to run them whether they are Repulsion Induction (RI),
Capacitor (Cap), or Split-Phase (SP) type.
If the electric motor is connected to a hard starting load such as an air
compressor, it will require more starting current. If it is connected to a
light load, or no load such as a power saw, it will require less starting
current. The exact requirement will also vary with the brand or design
of the motor.
Self-exciting generators respond to severe overloading differently than
utility power. When overloaded, the engine is not able to supply enough
power to bring the electric motor up to operating speed. The generator
responds with high initial starting current, but the engine speed drops
sharply. The overload may stall the engine. If allowed to operate at very
low speeds, the electric motor starting winding will burn out in a short
time. The generator winding might also be damaged.
CAUTION: EQUIPMENT DAMAGE
Running the generator set under these conditions may result in
damage to the generator stator as well as the motor winding.
The heavy surge of current required for starting motors is required for
only an instant. The generator will not be damaged if it can bring the
motor up to speed in a few seconds of time. If difculty is experienced
in starting motors, turn all other electrical loads off and if possible
reduce the load on the electric motor.

6REV D
60706-231
GASOLINE
When using gasoline, always use fresh, clean, unleaded fuel. The
engine is certied to operate on unleaded gasoline with a minimum
octane rating of 87 or higher. Gasoline containing no more the 10%
ethanol is acceptable.
CAUTION: EQUIPMENT DAMAGE
Do not use unapproved gasolines, such as E15 or E85. Do not mix
oil in the gasoline. Use of unapproved fuels will damage the engine
components and void the engine warranty.
Use of fuels with content of ethanol greater than shown above may
cause starting and/or performance problems. Always ensure that the
fuel is clean and free of all impurities.
WARNING: FIRE DANGER
Gasoline and its fumes are VERY explosive when proper precautions
are not taken.
Never use gasoline that has been stored for an extended period of
time as the fuel will lose its volatile properties and you will be left with
varnish residue. The varnish like substance will clog the carburetor and
will not burn properly.
The use of fuel additives, such as Sta-Bil, or an equivalent will minimize
the formation of fuel gum deposits. If a unit has been out of operation
for an extended period of time, it is best to drain old fuel from the
engine and replace with fresh fuel before attempting to start.
FUEL SUPPLY
The EC units provide exibility in where they get gasoline from.
Whether you are using our optional fuel tank, or supplying your own,
there are some important factors to consider. The fuel pump on the unit
is only capable of about 30” of lift in ideal circumstances. Tank size,
tank location, hose size, hose routing, and hot spots all play a role in
a successful fuel tank installation. Preferred fuel installations use 1/4”
hose that run straight to the engine with no drops or twists from an
adequately (15 gallons) sized fuel tank.
1. The fuel lift from the bottom of the tank to the fuel outlet on the
generator must not exceed 30”. If a greater lift is required, it
may be necessary to provide an additional electric fuel pump to
ensure the engine get a sufcient ow of fuel.
2. EPA regulations require the installation of a carbon canister on the
tank vent line. This is to prevent the escape of fuel vapors in to
the atmosphere.
3. You need to have a primer bulb in the fuel line to prime the fuel
from the tank to the fuel pump. The vacuum fuel pump on the
engine will not draw the fuel up from the tank until the line has
been properly primed.
4. In all cases the minimum fuel line size must be 1/4” or larger line.
And the fuel line must be certied for use with unleaded gasoline.
PREPARING THE UNIT
UNPACKING
CAUTION: EQUIPMENT DAMAGE
THIS UNIT HAS BEEN SHIPPED WITHOUT OIL. Failure to maintain
the engine oil at the proper level will result in serious engine damage.
When you unpack your engine-generator set be sure to remove all the
information sheets and manuals from the carton.
1. As you receive your unit, it is critical to check it for any damage. If
any damage is noted, it is always easiest to refuse the shipment and
let WINCO take care of the freight claim. If you sign for the unit, the
transfer of the ownership requires that you le the freight claim
2. Before proceeding with the preparations of your new generator
for operation, take a couple of minutes to ensure the unit you have
received is the correct model and review the specication pages in this
manual to ensure that this unit meets your job requirements.
VENTILATION
These engine generator sets use large amounts of fresh air for cooling.
When designing plans for your installation, special attention must be
paid to the ow of hot air from both the engine and the generator.
Both the engine and the generator must be supplied with a constant
ow of fresh air from the outside to ensure they don’t overheat. Some
provision must be made to remove the hot air out the enclosure.
Ambient temperature around the unit should not exceed 104°F.
Engine or generator failures resulting from inadequate ventilation
are considered abuse and not covered by the generator or engine
manufacturer’s warranty.
The engine exhaust from this engine must be vented to the outside.
When venting hot exhaust through any type of ammable wall be sure
to use exhaust thimbles to prevent res.
WARNING:
Failure to properly vent out the exhaust out of an enclosure can and will
kill you. Carbon monoxide is both invisible and orderless, it can build up
very rapidly in any enclosure not properly vented.

7REV D 60706-231
LUBRICATION
Before starting the engine, ll the crankcase to the proper level with
a good quality oil. The recommended grade oil and quantity of oil
required is listed in the engine operator’s manual and under the service
tab in this manual. This unit was shipped with most of the oil removed.
The engine normally holds 78 - 80 oz (2.4 - 2.5 qts) of oil. Since there
is some trapped in the engine, when lling the crankcase the rst time,
use the dipstick to ensure that you do not over ll the crankcase. The
full oil level mark on the dipstick is depicted in the following image.
Oil is added to the engine by removing the oil cap and adding oil at
this point. After lling the crankcase to the proper level, be sure you
properly tighten the oil ll cap.
NOTE: This engine generator must be on a level surface before you
check or add oil to the system.
The necessity of using the correct oil and keeping the crankcase full
cannot be overemphasized. Engine failures resulting from inadequate
or improper lubricant are considered abuse and not covered by the
generator or engine manufacturer’s warranty.
OIL RECOMMENDATIONS
Outdoor temperatures determine the proper oil viscosity for the
engines. Use the chart to select the best viscosity for the outdoor
temperature range expected.
OIL ALERT SYSTEM
This generator is equipped standard with the Briggs & Stratton low oil
pressure shutdown system. The low oil shutdown system is designed
to prevent severe damage caused by an insufcient amount of oil in
the crankcase. However, if the unit is repeatedly allowed to shutdown
on low oil pressure, progressive damage will be done to the engine,
shortening the engine’s life. The engine switch will remain in the “ON”
position when the unit is shutdown by the low oil pressure system.
CAUTION: EQUIPMENT DAMAGE
Allowing the engine to shutdown repeatedly on low oil level may cause
excessive wear which can be cumulative.
BATTERY INSTALLATION
You will need to connect this unit to a battery to operate it. Cables
have not been provided as length are going to vary depending on
your installation. These engines are all negative ground. The positive
battery cable must be connected to the open large terminal on the
start solenoid (This terminal may have a small 16 GA. wire on it for
the charging circuit). The negative cable should be attached to a good
ground on the engine. This is usually one of the starter mounting studs.
A twelve volt battery, rated at 300 CCA or larger is recommended for
this electric start generator set. Follow the battery manufacturer’s
recommendations for servicing and charging prior to use.
A 12 Volt battery, BCI group 26 rated at 500 CCA or larger is
recommended for this electric start engine-generator set. Follow the
battery manufacturers recommendations for servicing and charging
prior to use. Connect the battery to the electric start system using the
cables provided.
CAUTION: EQUIPMENT DAMAGE
These electric start engines are NEGATIVE GROUND. Use extreme
caution when connecting the battery. Connect the NEGATIVE battery
terminal to GROUND.
For your safety, always connect the positive battery cable to the “bat+”
terminal rst. Then connect the negative battery cable to the “Bat-”
terminal. Make sure all connections are clean an tight. Reverse the
sequence when disconnecting, disconnect the negative cable rst.
These engines produce enough direct current to keep the battery
charged under normal operating conditions, but were not intended to
be used as a battery charger.
WARNING: PERSONAL INJURY
Lead acid batteries produce explosive hydrogen gas when charging.
Keep sparks, ames, and burning cigarettes away from the battery.
Ventilate the area when charging or using the battery in an enclosed
space. Lead acid batteries contain sulfuric acid, which causes severe
burns. If acid contacts eyes, skin, or clothing, ush well with water. For
contact with the eyes, get immediate medical attention.
BATTERY CHARGING
Units have a small ywheel charger built into the engine ywheel
assembly for recharging the starting battery. This ywheel charger
generates a small AC current that passes through a diode assembly
to produce DC charging current of about 1 to 3 Amps. This circuit is
not designed to be used as a battery charging circuit to recharge dead
batteries.

8REV D
60706-231
STOPPING AND STORING
1. Move the key to the “OFF” position.
2. Turn off the fuel supply valve.
3. Before extended storage (over 30 days) certain precautions
must be taken to ensure the fuel doesn’t deteriorate and clog the
fuel system.
NOTE: The use of a fuel additive, such as Sta-Bil or equivalent will
minimize the formation of gum deposits during storage. The additive
may be added to gasoline in the engines fuel tank or to gasoline in a
storage container.
A. Add the fuel stabilizer to the fuel in the tank and run for 2 minutes
to circulate the stabilizer throughout the fuel system.
B. Remove the remaining fuel from the fuel tank, it must be drained
into an approved container.
C. Start the engine and allow it to run until all the fuel in the
carburetor and the fuel lines has been used up and the engine
stops.
NOTE: Running the engine to use up the fuel in the lines and
carburetor will still leave a small amount of fuel in carburetor. It is best
extended storage to treat the fuel before draining.
D. While the engine is warm, drain the oil and rell with fresh oil.
E. Remove the spark plug, pour approximately 1/2 oz. (15cc) of
engine oil into the cylinder and crank slowly to distribute the oil.
Replace the spark plug.
E. Clean dirt and chaff from cylinder, cylinder head ns, blower
housing, screen, and mufer areas.
F. Store in a clean and dry area.
OPERATING SPEED
The engine-generator must be run at the correct speed in order to
produce the proper electrical voltage and frequency.
CAUTION: EQUIPMENT DAMAGE
The output voltage should be checked to ensure the generator is
working properly prior to connecting a load to the generator. Failure to
do so could result in damage to equipment plugged into the unit and
possible injury to the individual.
All engines have a tendency to slow down when a load is applied.
When the electrical load is connected to the generator, the engine is
more heavily loaded, and as a result, the speed drops slightly. This
slight decrease in speed, together with the voltage drop within the
generator itself, results in a slightly lower voltage when the generator
is loaded to its full capacity than when running no load. The slight
variation in speed also affects the frequency of the output current.
This frequency variation has no appreciable effect in the operation of
motors, lights, and most appliances. However, electronic equipment
and clocks will be affected if correct RPM is not maintained. See Load
vs. Output chart.
Although individual units and models vary slightly, the normal voltage
and frequency of the engine-generator described in this manual are
approximately as follows, under varying loads:
INITIAL START UP
The throttle control on these generators is preset and locked to operate
at 3600 RPM (nominal) with no load speed set at 3690 RPM. Only
a trained service technician should be allowed to adjust this speed
setting.
NOTICE: ENGINE START LOCKOUT
This unit will not start if it is low on oil. The lubricating oil level must be
at the full mark before the engine will start and run.
BASIC OPERATION
CAUTION: EQUIPMENT DAMAGE:
Always start the unit with the circuit breaker open, never start with the
load applied. Always keep the battery charged, especially during cold
weather operation.
1. Turn on the fuel supply
2. Using the primer bulb, make sure the fuel is pumped up the the
fuel pump on the engine.
3. Move the choke to the full “ON” position for starting. A warm
engine will require less choking than a cold one.
4. Turn the key to the start postion. Thart starter life is improved
by using shorter start cycles. Do not operate the starter more than
15 seconds during each minute. Repeat as necessary.
5. When the engine starts, release the key and open the choke
gradually.
6. The engine should promptly come up to operating speed.
CAUTION: EQUIPMENT DAMAGE
Never permit the choke to remain on after the engine has run for a
short time. It is not necessary to choke the engine when it is warm.
Avoid over-choking.
STARTING HINTS
1. COLD WEATHER
A. Use the proper oil for the temperature expected.
B. Use fresh winter grade fuel. Winter grade gasoline is blended to
improve starting. Do not use summer grade gasoline.
2. HOT WEATHER
A. Use the proper oil for the temperature expected.
B. Use only summer blended gasoline. Using gasoline left over from
winter may cause the unit to vapor lock.

The speed of the engine was carefully adjusted at the factory so that
the generator produces the proper voltage and frequency. For normal
usage, the speed setting should not be charged. If the generator is
being run continuously on a very light load, it is often advisable to lower
the operating speed slightly.
CAUTION: EQUIPMENT DAMAGE
SPEED ADJUSTMENTS SHOULD ONLY BE MADE BY A QUALIFIED
SERVICE TECH. Whenever making any speed adjustments, check the
unit with a voltmeter and a frequency meter or a tachometer and be
sure the voltage and speed are correct.
Lower voltage may damage both the generator and any load connected
to it. Running the engine at excessively high speeds results in high
voltage, which may signicantly shorten the life of appliances being
used.
Output voltage should be checked periodically to ensure continued
proper operation of the generating plant and appliances. If the
generator is not equipped with a voltmeter, it can be checked with a
portable meter. Frequency can be checked by using an electric clock
with a sweep second hand. Timed against a wrist watch or a stop
watch, the clock should be correct within +/- 2 seconds per minute.
CONNECTING THE LOADS
Failure to properly limit and balance the load applied to the generator
will cause the generator to produce low voltage and may damage
the engine generator set. It may also cause severe damage to the
loads connected to the generator at the time. Improper loading of the
generator set constitutes abuse and will not be covered by warranty.
A 60 Amp receptacle (NEMA 14-60) has been provided to allow
the connection of loads to the generator on the EC18000VE. This
receptacle is a 4-wire, full load receptacle protected by a 60 Amp
breaker mounted in the control box on top of the generator.
With the EC22000VE, the load wiring must be wired directly in the 80
Amp breaker mounted in the control box on top of the generator. When
wiring directly to the circuit breaker in the box, be sure to connect a
neutral wire and ground wire to the appropriate locations in the control
box.
Your individual loads must be protected by individual circuit breakers
mounted in some type of distribution panel. This location will also be
where you will install your neutral to ground bond. You must wire four
separate wires from the generator (2-hot, 1- neutral, and 1-ground) to
the distribution panel.
APPLYING THE LOADS
Allow the engine to warm up for two or three minutes before applying
any load. This will allow the engine to reach normal operating
temperature and oil to circulate throughout the engine. A shot warm-up
time will permit the engine to work more efciently when the load is
applied and will reduce the wear in the engine, extending its life.
Receptacles have been provided to allow loads to be connected to the
generator. The loads should be added one at a time. If a large motor
is being started: or multiple motors are being started, they should be
started individually and the largest should be started rst.
CAUTION: EQUIPMENT OVERLOAD
Keep the generator load within in the generator and receptacle
nameplate rating. Overloading may cause damage to the generator
and/or the loads.
Most electric tools and appliances will have the voltage and amperage
requirements on their individual nameplates. When in doubt, consult
the manufacturer or a local electrician. The nameplate amperage rating
for electric motors can be misleading. See “Starting Electric Motors” in
the Unit Capabilities.
These engine-generator sets are inherently self regulating based on
engine speed. The engine governor will automatically adjust itself to
the load. No harm to the generator will result if it is operated with no
load connected. The generator is a limited source of electrical power,
therefore, pay special attention to the receptacle and generator ratings.
GROUNDING
All units must be grounded. Different installations will require different
grounding requirements. Depending on your installation, ensure that
the ground meets your governing codes.
WIRING
For your safety, all wiring must be done by a qualied electrician
and conform to the National Electric Code and comply with all state
and local codes and regulations. Check with local authorities before
proceeding.
CAUTION: EQUIPMENT DAMAGE
Failure to properly limit and balance the load a[[lied to the generator
will cause the generator to produce low voltage and may damage
the engine generator set. It may also cause severe damage to the
loads connected to the generator at that time. Improper loading of the
generator set constitutes abuse and will not be covered by warranty.

ENGINE CARE
If major engine service or repair is required, contact
an authorized engine service center. The manufac-
turer of these engines has established an excellent
world-wide engine service organization. Engine ser-
vice is very likely available from a nearby authorized
dealer or distributor. Check the yellow pages of your
local telephone directory under “Engines-Gasoline”
for the closest engine repair center or ask the dealer
from whom you purchased the power plant.
1. Change the oil after the first 5 hours of operation
and yearly or 100 hours thereafter under normal op-
erating conditions. Change engine oil every 50 hours
of operation if the engine is operated under heavy
load, or in high ambient temperatures.
a. Start the engine and warm it up, stop the engine
and remove the spark plug wire to prevent it
from accidently being started.
b. Remove oil drain plug at base of the engine
(Ref “B”) and drain the oil into an approved
container.
c. Remove the oil filter (Ref “C”) and dispose of it
properly.
d. Before you install the new oil filter, lightly lubri-
cate the oil filter gasket with fresh clean oil.
e. Install the oil filter by hand until the gasket
contacts the oil filter adapter, then tighten the oil
filter 1/2 to 3/4 turns.
f. Replace oil drain plug.
g. Remove oil filler plug and refill with new oil.
Refer to the table on page 5 for the proper
grade of oil based on your operating
temperature.
NOTE: This engine requires 78 to 80 ounces of oil
if it is completely drained. Use caution when refilling
the engine as some residual oil may have remained
in the engine. Always use the dipstick when filling
the engine with oil to prevent overfilling.
h. Replace filler plug.
I. Start the engine and warm it up.
J. After warming up the engine, recheck the oil
level and refill as necessary to bring it to the
proper level. See page 5 for proper oil level.
2. Checking the Oil Level: The oil level must al-
ways be checked before the engine is started. Take
care to remove any dirt or debris from around the
oil fill plug before removing. Be sure the oil level is
maintained. Fill to the “FULL” mark on the dipstick.
3. Dual Element Air Filter: Clean and/or replace
foam pre-cleaner and air filter annually or every 100
hours. Service more often under dusty conditions.

GENERATOR CARE
Proper care and maintenance of the generator is necessary to ensure a
long trouble free life.
EXERCISING THE GENERATOR
The generator should be operated every three to four weeks. It should
be operated for a period of time sufcient to warm the unit up and to
dry out any moisture that has accumulated in the windings. If left, this
moisture can cause corrosion in the winding. Frequent operation of the
engine-generator set will also ensure that the set is operating properly
should it be needed in an emergency.
GENERATOR MAINTENANCE
Any major generator service, including the installation or replacement
of parts, should be performed only by a qualied electrical service
technician. USE ONLY FACTORY APPROVED REPAIR PARTS.
A. Bearing - The bearing used in these generators is a heavy duty,
double sealed ball bearing. They require no maintenance or
lubrication.
B. Receptacles - Quality receptacles have been utilized. If a
receptacle should become cracked or otherwise damaged,
replace it. Using damaged or cracked receptacles can be both
dangerous to the operator and destructive to the equipment.
CLEANING
Remove dirt and debris with a cloth or brush. DO NOT use high
pressure spray to clean either the engine or the generator. The high
pressure spray could contaminate the fuel system and the generator
components.
1. Keep the air inlet screen on both the engine and generator free of
any dirt or debris to ensure proper cooling. At least yearly, remove
the blower housing on the engine and clean the chaff and dirt out of
the engine cooling ns and y wheel. Clean more often if necessary.
Failure to keep these areas clean may cause overheating and
permanent damage to the unit.
2. Periodically clean mufer area to remove all grass, dirt, and
combustible debris to prevent a re.
3. On engine mufers equipped with spark arresters, the spark arrester
must be removed every 50 hours for cleaning and inspection. Replace
if damaged.
CARBON CANISTER
Designed to collect, store, and dispose of fuel vapors created in the
fuel tank/fuel system. The canister should last the life of the unit as long
as it stays dry.
