!
• 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.

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. Consult the local fire department for
any questions pertaining to fire extinguishers.
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.
• Bryant generator sets 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.

Section 1 - General Information
Bryant Liquid-cooled 15 kW Generators
1.1
GENERATOR
1.3
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.
These models are available. They are rated as follows:
Model ASPAS1BBL015: Provides 15,000 watts (15
kW) of single phase power.
AUTOMATIC SYSTEM OPERATION
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.
When UTILITY source voltage has been restored, the
switch re-transfers back to the utility source voltage
and the generator then shuts down.
Please reference the transfer switch manual for specific information.
!
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
This generator system includes a matched automatic
transfer switch which is intended to be used in conjunction with the generator. It is supplied with a
NEMA 3R enclosure. 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.
• Failure to utilize a Bryant transfer switch with this
generator will void the warranty.
1.4
GENERATOR AC CONNECTION
SYSTEMS
The generator was shipped from the factory with its
stator AC output leads connected in a single-phase,
three-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

GENERATOR FUEL SYSTEM
The generator has been factory tested and adjusted
using a natural gas fuel system. If propane (LP
requirements) gas is preferred, refer to Section 1.12.
Recommended fuels should have a Btu content of at
least 1,000 Btus per cubic foot for natural gas and at
least 2,520 Btus per cubic foot for LP gas. Ask the fuel
supplier for the Btu content of the fuel being used.
‹ 1.7.1
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
Fuel pressure for a natural gas set up should be five
inches to 14 inches of water column (0.18 to 0.5
psi) at all load ranges.
Fuel pressure for an LP vapor set up should be 11
inches to 14 inches of water column (0.4 to 0.5
psi) at all load ranges.
NOTE:
A separate gas line and regulator may be needed
to assure proper gas pressure to the generator.
Improper gas pressure can cause hard starting and
affect engine durability.
‹ 1.7.2
!
1.7
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.
HIGH COOLANT TEMPERATURE
SWITCH
This 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
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).
Figure 1.3 - Engine Protective Devices
‹ 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).

OVERCRANK SHUTDOWN
After 90 seconds of crank-rest cycles, this function
ends cranking if the engine fails to start in that
90-second span.
‹ 1.7.6
‹ 1.7.4
OVERSPEED SHUTDOWN
The Pre-pack circuit board on liquid cooled units

1.14 ENGINE OIL RECOMMENDATIONS
1.16 BEFORE INSTALLATION
The unit has been filled with 15W-40 engine oil at the
factory. Use a high-quality detergent oil classified “For
Service SJ or latest available.” Detergent oils keep the
engine cleaner and reduce carbon deposits. Use oil
having the following SAE viscosity rating, based on
the ambient temperature range anticipated before the
next oil change:
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 Sections 2.5 and 2.6.
Temperature
Above 80° F (27° C)
32° to 80° F (-1° to 27° C)
Below 32° F (0° C)
Oil Grade (Recommended)
SAE 30W or 15W-40
SAE 20W-20 or 15W-40
SAE 10W or 15W-40
NOTE:
Synthetic oil is highly recommended when the
generator will be operating in ambient temperatures which regularly exceed 90° F and/or fall
below 30° F.
The generator’s rated wattage/amperage capacity
must be adequate to handle all electrical loads that
the unit will power. The critical (essential) loads may
need to be grouped together and wired into a separate “emergency” distribution panel.
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
STANDBY GENERATOR
INSTALLATION
DANGER
!
Any attempt to crank or start the engine before
it has been properly serviced with the recommended oil may result in an engine failure.
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.
1.15 COOLANT RECOMMENDATIONS
Use a mixture of half low silicate ethylene glycol base
anti-freeze and deionized water. Cooling system
capacity is about 8 U.S. quarts (7.6 liters). Use only
deionized 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. It is also recommended
that any soluble oil inhibitor is NOT used for
this equipment.
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.
This genset must be installed on a level surface. The
base frame must be level within 1/2 inch all around.
!
After the system has been installed, do nothing
that might render the installation in noncompliance with such codes, standards and regulations.

• Where strong prevailing winds blow from one
direction, face the generator air inlet openings into
the prevailing winds.
• 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 six inches thick and should
extend beyond the enclosure to a distance of at least
three inches on all sides. See Section 6, Installation
Diagram.
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.
Figure 2.1 – Basic Standby Electric System
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 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. Five feet allowance
of space is recommended on all sides. Local codes
may supercede this recommendation.
Bryant recommends the use of a Bryant transfer
switch in conjunction with this generator.

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, or greater
than, 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.
• Ampere rating of the transfer switch must be equal
to, or greater than, the ampere rating of the normal
incoming utility service.
• The transfer switch is installed between the utility
service entrance and the building distribution
panel.
2.7
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 Bryant
2.8
GENERATOR AC NEUTRAL
CONNECTIONS
Bryant 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.
!
2.9
Failure to connect the generator neutral properly will result in unbalanced line-to-neutral
voltages. Resulting high voltages will cause
equipment damage.
TRANSFER SWITCH SIGNAL
CONNECTIONS
It is necessary to connect the control wires between
the generator and the transfer switch.
Control system interconnections consist of N1, N2,
T1, T2 and leads 23 and 194. Control system interconnection leads must be run in a conduit that is separate from the AC power lead. Recommended wire
gauge sizes for this wiring depends on the length of
the wire, as recommended below:
MAXIMUM WIRE LENGTH
460 feet (140m)
461 to 730 feet (223m)
731 to 1,160 feet (354m)
1,161 to 1,185 feet (565m)

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 the NORMAL source voltage at the
transfer switch is correct and the system is
ready to be put into 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 the 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.
The recommended battery is Group 26, 12V negative
ground, 525 CCA/75 AH minimum. 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

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 “Scheduled Maintenance,” Section 4.7, for air
cleaner maintenance.
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. Apply a
coat of automotive type wax once a year to help prevent corrosion.
Once each year, have the generator cleaned and
inspected by a 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.

Section 4 — Maintenance
Bryant Liquid-cooled 15 kW Generators
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
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
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
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.
‹ 4.6.3
BATTERY MAINTENANCE
The battery should be inspected per the “Scheduled
Maintenance,” Section 4.7. 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.
!
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 the 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.
!
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.

•
Turn off utility supply to engine water heater.
•
Turn off the battery charger by turning off utility supply to the transfer switch.
•
Remove the negative battery cable.
The battery charger must be turned off BEFORE removing the battery cable to prevent an over current condition from burning out sensitive control panel components and circuits.
Following all maintenance, reverse these steps to insure the unit is returned to standby setup for normal
operation when required.
2 A break-in service inspection of the generator set to insure it is ready to operate and carry the load when
required, and to identify any potential problem areas.
Performed ONLY ONCE following the first three months or the first 30 hours of operation after purchase of
the unit and requires approximately 2.5 man-hours per unit to complete.
This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge
to accomplish and should be performed only by a dealer.
3 An operational inspection of the generator set to insure it is ready to operate and carry the load when required,
and to identify any potential problem areas.
Performed semi-annually or following each 50 hours of operation of the unit and requires approximately 1.5
man-hours per unit to complete.
This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge
to accomplish and should be performed only by a dealer.
4 A mid-level inspection of the generator set to insure it is ready to operate and carry the load when required, and
to identify any potential problem areas.
Performed annually or following each 100 hours of operation of the unit and requires approximately 4.0
man-hours per unit to complete.

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.
Warranty service can be arranged by contacting Generac Power Systems, Inc..
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 “Bryant Two Year
Limited Warranty for Prepackaged Emergency Automatic Standby Generators” 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 Bryant 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 Bryant
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.
To arrange for emissions equipment warranty or if you have any questions regarding your warranty rights and responsibilities, you should contact Generac at the following address:

Section 10 – Warranty
Bryant Liquid-cooled 15 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.
EMISSION RELATED PARTS INCLUDE THE FOLLOWING:
1) Fuel Metering System:
