INTRODUCTION
PRODUCT DESCRIPTION
The package standby system is designed to automatically
provide standby power to unattended loads during
electrical outages. Upon interruption of normal electrical
service, the packaged standby system electrical control
circuits will automatically start the engine. The generator
will produce electrical power and the Automatic Transfer
Switch (ATS) will automatically transfer the electrical loads
to the
engine-generator set. Upon restoration of normal electrical
service the emergency transfer switch will sense return of
the normal commercial power. The Automatic Transfer
Switch will transfer the load back
to the normal commercial power source. The engine
control circuits will begin a cool-down cycle, after which the
fuel supply will be shut off and the engine ignition system
disabled.
AUTOMATIC TRANSFER SWITCH (not included)
A wall mounted ASCO 185 Automatic Transfer Switch (ATS)
designed for inside or outside installation is recommended.
The transfer switch is UL1008 approved. A seven day
electronic exerciser circuit is installed
in the ATS as standard equipment. The ATS also contains
the power failure sensing circuitry necessary to start and
stop the engine generator set. The transfer switch is also
equipped standard with a 3 second start delay, and a 15
second transfer delay to allow the engine to warm up
before transferring the load to the generator. When the
line power is restored the ATS has a 5 minute transfer delay
to allow the incoming utility to stabilize before transferring
back to line power and then an additional 2 minute engine
cool down delay before the engine shuts down. Read
and understand the ATS owners manual before installing,
servicing or operating the transfer switch.

ENGINE / GENERATOR
The engine generator set consists of a Briggs & Stratton
Vanguard, twin cylinder, four cycle air cooled engine. The
engine is factory equipped to run on LP or NG fuel. The
engine operates at 3600 rpm and frequency regulation
is maintained by the engine governor within 4 cycles
variation (62.5 Hz - 58.5 Hz) from no load to rated load. The
generator is a brushless, single bearing, direct drive, rotating
field design. The generator is connected to the engine’s
tapered (quill) crankshaft extension. The engine generator
is mounted in a drip-proof enclosure for outside installation.
Connection boxes and terminal blocks are provided for all
customer connections (both AC output and DC control). A
customer supplied 12 volt 500 CCA (BCI group 26) battery
is required to complete the installation.
NOTICE:
This unit will automatically transfer if a power outage occurs
while running in an exercise mode.
TESTING POLICY
Before any generator is shipped from the factory, it is fully
checked for performance. The generator is loaded to its
full capacity, and the voltage, current, and frequency are
carefully checked.
Rated output of generator is based on engineering tests
of typical units, and is subject to, and limited by, the
temperature, altitude, fuel, and other conditions specified
by the manufacturer of applicable engines.

560706-211/F
PREPARING THE UNIT
UNPACKING
CAUTION: EQUIPMENT DAMAGE
When you unpack your new generator, be sure to remove
all of the information sheets and manual 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 file 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 specification pages in this manual to ensure that this
unit meets your job requirements.
CAUTION:
These units are shipped with oil. Be sure to check oil levels
before operating. See engine manufacturer’s instruction
manual for recommended oil requirements before initial
starting.
INSTALLATION
WARNING:
Before proceeding with installation, be sure the operation
selector switch is in the stop position.
These engine generator sets are designed to be mounted
on a pad outdoors only. The transfer switch is mounted
next to your electrical entrance or distribution panel
inside or outside the building. Consult a qualified, licensed
electrician or contractor to install and wire the transfer
switch. The installation must comply with all national, state
and local codes. Before beginning the installation process
check the rating of the generator set and its transfer
switch rating. Be certain they can handle the intended
load and are compatible with the entrance voltage,
phase and current ratings. Plans for installation should
be prepared with proper attention to mechanical and
electrical engineering detail to assure a satisfactory system
installation. The information in this manual is offered only as
a guide to finalizing your installation plans.
ENGINE-GENERATOR SET MOUNTING
WARNING: Personal Injury:
The enclosures on these units can become very hot
adjacent to the exhaust areas. Special care must be taken
when installing these units to insure that the risk of contact
by people is minimized.
The unit’s main frame should be bolted to a pad that meets
local code. Various materials, including concrete and
composites, are acceptable as long as they are structurally
sound supporting the weight of the unit and preventing
movement during operation. The mounting holes on the
base of this unit is 0.563” in diameter. The engine-generator
is mounted on a sub-frame which is isolated with special
shock mounts on the main frame. This allows the engine-
generator to vibrate without affecting the control panel on
the main frame.
Do not install any shock mounts between the base frame
and the pad. Engine vibration will be transmitted to the
control panel causing erroneous start/stop cycles and
premature control failure.
These units should be mounted a minimum of 24” from a
structure. This will allow for ample room to maintain and
work on the generator set.
Units must be installed in accordance with all local, state,
and national codes. Consult your local agency for specific
requirements.
FUEL INSTALLATION
The fuel supply should be as close as possible to the
engine. This will reduce the installation cost of fuel runs.
The information in this manual is offered to assist you in
providing the proper fuel for your engine. However, this
information is only provided to inform you of the engine’s
requirements and assist in making you aware of the
decisions you must make. In no case should the instructions
and information provided be interpreted to conflict with
any local, state or national codes. If in doubt, always consult
your local fire marshal, gas supplier or building inspector.
WARNING: FIRE HAZARD:
All fuel runs should be installed by a licensed fuel supplier.
To connect the fuel line to the generator set you will
connect your incoming fuel line to the 3/4 inch NPT fitting
located on the left side of the engine-generator set. This
fitting is shipped with a plastic plug installed to insure
the fuel system stays clean. For all vapor fuel systems the
delivery pressure of the fuel to the fuel solenoid on the unit
must be four to six ounces psi (per square inch) or 7 to 11
inches W.C. (water column). These fuel pressures are critical;
failure to provide the proper pressure can cause many
problems ranging from a unit that will not start to causing
damage to the fuel system.
These units are normally tested on Natural Gas and will
have a tag hanging on the fuel hose indicating on what
fuel your unit was factory tested. If you are running on LP
or have to change fuel types at any time, see information
on page 8 on NG/LP CONVERSION. INSTALLING THE FUEL
LINE.
NOTICE:
The engine generator sets are properly adjusted before they
leave the factory. A tag is attached to the unit that specifies
the fuel, natural gas (NG) or propane vapor (LP) that the
unit was set up and tested on.
NATURAL GAS or LP VAPOR PIPE SIZE
Size of pipe normally required for generators operating on
natural gas or LP vapor. Unit location will determine the
size of fuel line that is required to supply the engine with a
constant fuel pressure and volume.
LIQUID PROPANE VAPOR (LP)
Refer to the tables on the following pages for fuel line size
and recommended tank size. For distances of 50 feet or
over, a two regulator fuel system is recommended. This is
accomplished by installing a primary regulator at the tank
which will reduce the tank pressure down to 10 to 15
lbs. A low pressure regulator is installed to further reduce
the fuel pressure to the required four (4) to six (6) oz.

6
60706-211/F
operating pressure. This low pressure regulator must be
at least 10 feet from the engine generator set; any closer
installation will require a larger line be installed to provide
a fuel reservoir. This is also true for the single low pressure
regulator, it should also be a minimum of 10 feet from the
unit. If this is not done, the demand regulator on the unit
and the pressure regulator in the fuel line will interfere
with each other. When the two (2) regulator system is
used on LP, a fuel line size of 1/2 to 5/8 inch is generally
adequate for distances up to 300 feet from the primary to
the low pressure regulator. Consult your local fuel supplier
for your exact requirements . The appropriate line size from
the following table is then installed from the low pressure
regulator to the generator set.
Feet* Size of pipe
Up to 25 ft ¾” pipe
25 - 100 ft 1” pipe

NATURAL GAS (NG)
The primary regulator (fuel meter) on the building should
deliver the correct volume and pressure to the generator
set. This regulator must be sized to deliver the required
BTU’s to the generator set and all other appliances in the
building. If the primary regulator (fuel meter) is a high
pressure regulator, then a low pressure regulator must be
installed to bring the pressure down to 4-6 oz. (7-11 inches
water column) of pressure. This low pressure regulator must
be at least 10 feet from the engine generator set; any closer
installation will require a larger line be installed to provide
a fuel reservoir. If this is not done, the demand regulator
on the unit and the pressure regulator in the fuel line will
interfere with each other. This regulator must be sized to
accommodate the demand of the generator set and any
other appliance connected to it. See the following table for
the correct size of pipe to be installed.
Feet* Size of pipe
Up to 25 ft ¾” pipe
25 - 100 ft 1” pipe
Over 100 ft Use a two regulator system
*Allow an additional 3 feet for each standard elbow. DO
NOT use ‘street ells’ (restrictive).
WARNING: PERSONAL DANGER:
Do not use galvanized pipe in fuel line runs. The galvanized
coating can become eroded and flake off, causing possible
obstructions in the regulator or fuel valve. The results could
range from inoperative engine to hazardous fuel leaks.
CAUTION:
Be careful when sealing gas joints. Excessive sealing
compound can be drawn into the solenoid, regulator or
carburetor causing an engine malfunction.
FUEL PRESSURE
Correct fuel pressure cannot be stressed enough. The most
common cause for inoperative systems is an inadequate
or incorrect fuel pressure. Performance of the engine is in
direct relation to the correctness of the fuel system. Shown
below is a diagram of a typical LP vapor fuel installation.
Notice the following tables give two different units of
measuring fuel pressure. The first and most accurate is
the use of a simple water manometer. A manometer is
calibrated in inches of water column . The second is with a
pressure gauge calibrated in ounces per square inch.
Reference numbers 1 through 3 in the diagram above are
system parts supplied by the customer. Reference number 4
is on the generator.

NG/LP FUEL CONVERSION
These generator sets are factory tested on Natural Gas
and will require no modifications for normal operation on
Natural Gas. The carburation system has been preset and
anti-tamper plugs have been installed in the carburetor as
required by the EPA.
If you are operating on LP fuel you will have to make the
following modifications: On the left side of the engine,
above the starter there is a small two wire white connector
lying loose. The wires will be labeled 1 and 21. This
connector has to be plugged into the mating two-wire
white connector coming out of the carburetor area on the
left side of the unit. This connection will engage an orifice
in the carburetor allowing the unit to operate on Liquid
Propane vapor fuel. NO other adjustments are required.
If you are reinstalling a unit that has been operating
on Liquid Propane vapor and you now want to operate
it on Natural Gas all that you will need to do is
unplug this connector.
LUBRICATION
Before starting the engine, fill 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 48 ounces (1.5 quarts) of oil.
Since there is some trapped in the engine, when filling the
crankcase the first time, use the dipstick (‘A’ in following
image) to ensure that you do not over fill the crankcase. The
full oil level mark on the dipstick is depicted in the following
image as ‘B’.
Oil is added to the engine by removing the oil cap and
adding oil at this point. After filling the crankcase to the
proper level, be sure you properly tighten the oil fill cap (‘C’).
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 with a low oil shutdown system.
This Briggs & Stratton engine uses an oil pressure switch
system. If the oil level drops below a certain point the low
oil module on the engine will shut it down. This low oil
warning system will automatically stop the engine before
the oil level reaches critical danger point. This feature is
designed to prevent costly repairs and downtime.

INSTALLING THE BATTERY
CAUTION:
In the following battery installation procedure, check to be
sure the selector switch remains in the ‘off’ position. This
should be your last step before initial start-up.
A customer supplied twelve-volt battery is required to
complete the installation. Installation of the highest CCA
rated battery, within the correct BCI group (size), will
increase cold weather starting performance. Gel batteries
should not be used with the battery tender installed in the
generator enclosure.
Voltage BCI Group MIN. CCA Rating
12 26 500
Installation and servicing of batteries must be performed
or supervised only by persons knowledgeable of batteries
and the required precautions. Keep unauthorized persons
away from batteries. When installing or replacing batteries,
use the proper group/size starting battery. The battery
should be a maintenance free lead acid design. Deep cycle
batteries will not work for this application.
CAUTION: PERSONAL DANGER:
NEVER dispose of a battery in a fire. The battery is capable
of exploding.
DO NOT open or mutilate the battery. Released electrolyte
is known to be harmful to the skin and eyes and to be very
toxic.
These generator sets are all NEGATIVE ground. Be very
careful not to connect the battery in reverse polarity, as
this may short circuit the battery charging system on the
engine.
CAUTION:
A battery presents a risk of electrical shock and high short
circuit current. The following precautions must be observed
when working with batteries.
1. Remove watches, rings, and other metal objects.
2. Use tools with insulated handles.
3. Check both the battery cable ends and the battery
posts to be sure they are free of corrosion.
4. Always connect the battery positive cable first and then
connect the battery negative cable. When removing
the battery cables from the battery, reverse the
procedure and disconnect the negative cable first and
then the positive cable.
5. Be sure all connections are tight and coat the terminals
and cable ends with dielectric grease.
WARNING:
The electrolyte is a diluted sulfuric acid that is harmful to the
skin and eyes. It is electrically conductive and corrosive, The
following precautions must always be taken.
1. Always wear full eye protection and protective
clothing.
CAUTION: EQUIPMENT DAMAGE
Allowing the engine to shutdown repeatedly on low oil
level may cause excessive wear which can be cumulative.
2. Where electrolyte contacts skin, wash off immediately
with water.
3. If electrolyte contacts the eyes, flush immediately and
thoroughly with water. Seek immediate medical
attention.
4. Spilled electrolyte is to be washed down with an acid
neutralizing agent. A common practice is to use a
solution of one pound of bicarbonate of soda (baking
soda) to one gallon of water. The bicarbonate of soda
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.
DANGER: EXPLOSIVE FIRE RISK:
Never smoke near batteries Do not cause a flame or spark
in the battery area. Always discharge static electricity from
your body before touching batteries by first touching a
ground metal surface.
SERVICING BATTERIES
Batteries used on these units may over time lose water.
This is especially true if you are using a trickle charger to
maintain your battery. When refilling the battery with
water, use only distilled water. Tap water will shorten the
service life of the battery.
Never fill the battery above the fill line. Over filling above
the upper level line may cause electrolyte to overflow,
resulting in corrosion to the engine or nearby parts.
Immediately wash off any spilled electrolyte following the
procedure above.
BATTERY CHARGING
Units equipped with electric start have a small flywheel
charge built into the engine flywheel assembly for
recharging the starting battery. This flywheel charger
generates a small AC current that passes through a
rectifier/regulator assembly on the engine to produce a DC
charging current. This circuit is not designed to be used as a
battery charging circuit to recharge dead batteries.
CAUTION: EQUIPMENT DAMAGE:
Always connect the positive cable first and the negative
cable last. When disconnecting, remove the negative cable
first and the positive cable last. Failure to connect and
disconnect in the proper sequence can cause equipment
damage.
Observe polarities: connect the positive (+) battery
terminal to the (+) cable from the engine starter; the
negative (-) battery terminal is connected to the negative
cable (ground) from the engine generator assembly. All
connections must be clean and tight. Check the electrolyte
(fluid) in the battery periodically to be sure it is above the
plates. Never allow the battery to remain in a discharge
condition.
CAUTION: EQUIPMENT DAMAGE:
NEVER JUMP START these units. Doing so will destroy the
engine control module, rendering the unit non-operational.
Remove and fully recharge the battery before attempting to
start.

CONNECTING THE BATTERY
CHARGER
A two-stage battery tender is provided on all PSS series
generators. This battery tender charges at a rate of 750 mA
until the battery is fully charged and then automatically
switches to a 13.2 VDC float charger. The charger has an
indicator light on it. Red indicates it is charging, and green
indicates it is in storage mode (float charge). This charger is
mounted on the generator set which is located behind an
access cover in the rear of the unit.
The battery tender receptacle is to be powered by a GFCI
circuit and installed in accordance with the United States
National Electric Code. These AC wires can be run in the
same conduit as the other AC leads from the generator. It
is suggested that this circuit be fused for 15 Amps. Terminal
block connections have been provided in the customer
connection area of the engine-generator set. See following
diagram.
NOTICE:
The battery tender is not intended to recharge a battery
which has become completely discharged. It is designed to
produce enough current to recharge a slightly low battery
and maintain a fully charged battery.
SOLAR CHARGER OPTION
(If Equipped)
The WINCO solar option consists of two parts; one the solar
panel and two the Sun Guard charge controller. The solar

To gain access to the customer connections, remove
the end door panel opposite the muffler. All AC and DC
connections to the ATS, 120 Volt power connection for
battery charger, and battery installation are made behind
this panel. See drawings for generator set and pad layout
featured within this manual.
Two hot leads, one neutral, and one ground lead are
required between the generator and the ATS or distribution
panel. The two power leads from the generator are marked
G1 and G3. Next install the two leads, one neutral, and one
ground from the generator set to the ATS or distribution
panel.
In addition to the power leads, install a three wire 120
Volt, 15 Amp circuit from your distribution panel to the
generator. This circuit will be used to power the battery
charger, optional block heater and optional battery heater.
The last four wires you will install are the DC control leads
(14 or 16 gauge) for the start circuit in the ATS. These
connections will be discussed later in more detail.
WINCO UL ATS (ASCO 185)
See the ASCO installation manual for additional details on
proper wiring of the Automatic Transfer Switch.
The standby generator terminals in the ATS are marked
“ALTERNATE L2 & L6”. The “hot” leads G1 and G3 from
the generator are connected to the terminals L2 & L6.
The normal line power terminals in the ATS are marked
“PREFERRED - L1 & L5”. The “hot” line power leads are L1
and L3 from the utility power supply. They are connected to
terminals L1 and L5.
The load terminals in the ATS are marked “LOAD - L3 & L7”.
The leads to the load distribution panel are connected to
terminals L3 & L7.The neutral leads from all three locations
are connected to the isolated terminal lugs on the sidewall
of the cabinet. This terminal block is labeled “NEUTRAL” and
the terminal lugs are mounted on red isolation standoffs.
The ground leads from all locations are connected to the
grounded terminal lugs also located on the side wall. This
set of terminals is labeled “GROUND”.
INSTALLATION NOTES:
The load current carrying wires (L) and (T) must be sized
to handle the maximum load current without excessive
voltage drop. By code, the wire must be heavy enough
to handle the full current rating of the main line circuit
breaker (or fuse) in the entrance (or sub-panel) protecting
the contactor switch. All wires should be installed in
rigid or flexible conduit. Because of the many different
types of service, feeder, and distribution equipment, no
specific wiring instructions can be provided. It is, however,
recommended that copper wire be used. In all cases it is
essential that while the load is connected to the generator,
there can be absolutely no feedback from the generator
to the power line or the power line to the generator.
When properly installed, the normal ATS control and safety
systems will eliminate all paths for feedback. Check with
your local electrical inspector on applicable local, state and
federal codes.

CAUTION:
Never run the AC and DC wiring on the same conduit.
ASCO 185 UL SWITCH
Your DC connection points in the ASCO 185 UL ATS are on
the terminal block on the bottom of the controller in the
lower left hand corner of the ATS panel. The terminal block
(TB7) is numbered 1 through 9. These terminals will accept
# 22 - # 14 AWG stranded wire. It is recommended that you
use # 16 AWG for distances up to 200 feet. You need to run
two (2) wires from the engine generator set to the transfer
switch. You will be using terminals 4 and 5, wire Start # 23
will connect to terminal # 5 and wire Battery Negative #
1 will connect to terminal # 4. See the following table and
illustration.
Wire # Purpose Recommended
Color
#23 Start Black

WARNING:
A service disconnect must be installed in front of the ATS
panel as the ATS is not service entrance rated. This will
allow you to test the generator under load. Should you ever
have to work on the switch, you will be able to disconnect
the power and work on the switch cold without having the
power company pull your meter.
To wire the automatic transfer switch into the existing
wiring, first determine which circuits will be on the
emergency load circuit. If the entire load is to be transferred,
the transfer switch can be wired in directly after the watt-
hour meter and the service entrance, providing the service
entrance ampere rating is within the transfer switch’s rated
capability.
If only specific circuits are to be powered under emergency
power failure conditions, an additional distribution panel
designated “emergency distribution panel” must be
installed.
All selected emergency circuits are removed from main
distribution panels and reinstalled in the emergency
distribution panel. Suggested circuits: freezer, refrigerator,
furnace, emergency lights, sump pump, emergency outlet
circuits, etc. Total running load must not exceed generator
rating.

block in the ATS (L2 and L6 in the ASCO ATS). The voltage
should be 240 Volts plus or minus nominal. The frequency
should be between 61.5 to 62 Hertz (Hz). The Voltage
should also be checked between the hot terminals (L2 and
L6) and the neutral connection. The Voltage should be
about one half of the line to line Voltage.
OPERATING SPEED
The engine-generator must be run at the correct speed
in order to produce the proper electrical voltage and
frequency.
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.
