Study these SAFETY RULES carefully before install-

ing, operating or servicing this equipment. Become

familiar with this Owner’s Manual and with the unit.

The generator can operate safely, efficiently and reli-

ably only if it is properly installed, operated and

maintained. Many accidents are caused by failing to

follow simple and fundamental rules or precautions.

The manufacturer cannot anticipate every possible

circumstance that might involve a hazard. The warn-

ings in this manual, and on tags and decals affixed

to the unit are, therefore, not all inclusive. If a pro-

cedure, work method or operating technique is used

that the manufacturer does not specifically recom-

mend, ensure that it is safe for others. Also make

sure the procedure, work method or operating tech-

nique utilized does not render the generator unsafe.

DANGER

 Despite the safe design of this generator,

operating this equipment imprudently, neglect-

ing its maintenance or being careless can cause

possible injury or death. Permit only responsible

and capable persons to install, operate or main-

tain this equipment.

 Potentially lethal voltages are generated by

these machines. Ensure all steps are taken to

render the machine safe before attempting to

work on the generator.

 Parts of the generator are rotating and/or hot

during operation. Exercise care near running

generators.

 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 tech-

nician who is familiar with applicable codes, stan-

dards and regulations. The operator also must

comply with all such codes, standards and regula-

tions.

• 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 electri-

cal 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 monox-

ide 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 stan-

dards.

• 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 venti-

lating air is critical in any room or building hous-

ing the generator 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 seri-

ously 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.

• Inspect the generator regularly, and promptly

repair or replace all worn, damaged or defective

parts using only factory-approved parts.

 SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe

operation be copied and posted in potential hazard areas. Safety should be stressed to all

operators, potential operators, and service and repair technicians for this equipment.

The engine exhaust from this product

contains chemicals known to the state

of California to cause cancer, birth

defects or other reproductive harm.

Safety 001 Rev. 0 08/05

• Before performing any maintenance on the gen-

erator, 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 con-

ditions 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 gen-

erator. 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 personnel must stand on metal or concrete while

installing, operating, servicing, adjusting or repair-

ing 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) requires the

frame and external electrically conductive parts

of the generator to be connected to an approved

earth ground. 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 maxi-

mum 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 pos-

sibly fatal electrical shock.

• Connecting this unit to an electrical system nor-

mally 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 operat-

ing. 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 person-

nel, 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, imme-

diately 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 imple-

ment, such as a dry rope or board, to free the vic-

tim from the live conductor. If the victim is uncon-

scious, apply first aid and get immediate medical

help.

• Never wear jewelry when working on this equip-

ment. Jewelry can conduct electricity resulting in

electric shock, or may get caught in moving com-

ponents 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 extin-

guisher 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 com-

bustible materials are left in the generator com-

partment, or on or near the generator, as FIRE or

EXPLOSION may result. Keep the area surround-

ing the generator clean and free from debris.

• These 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 regulat-

ing the storage and handling of fuels. Inspect the

unit’s fuel system frequently and correct any leaks

immediately. Fuel supply lines must be prop-

erly installed, purged and leak tested according to

applicable fuel-gas codes before placing this equip-

ment 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.

EQUIPMENT DESCRIPTION

This equipment is a revolving field, alternating cur-

rent generator set. It is powered by a gaseous fueled

engine operating at 1800 rpm for 4-pole direct drive

units, 3600 rpm for 2-pole direct drive units and

2300 - 3000 rpm for quiet drive gear units. See the

Specifications section for exact numbers. The unit

comes complete with a sound attenuated enclosure,

internally mounted muffler, control console, main-

line circuit breaker, battery charger, and protective

alarms as explained in the following paragraph.

All AC connections, including the power leads from

the alternator, 120 volt battery charger input and

control connections to the transfer switch are avail-

able in the main connection box.

The generator incorporates the following generator

features:

• Rotor and Stator insulation is Class F rated as

defined by NEMA MG1-32.6, NEMA MG1-1.66.

The generator is self ventilated and drip-proof con-

structed.

• The voltage waveform deviation, total harmonic

content of the AC waveform and telephone influ-

ence factor have been evaluated and are acceptable

according to NEMA MG1-32.

ENGINE OIL RECOMMENDATIONS

The unit has been filled with 15W-40 engine oil at

the factory. Use a high-quality detergent oil classified

“For Service CC, SD, SE, SF.” 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:

 Any attempt to crank or start the engine before

it has been properly serviced with the recom-

mended oil may result in an engine failure.

NOTE:

For temperatures below 32° F, it is strongly recom-

mended to use the optional Cold Weather Start Kit

(part number listed in the Specification Section).

The oil grade for temperatures below 32° F is 5W-

30 synthetic oil.

COOLANT RECOMMENDATIONS

Use a mixture of half low silicate ethylene glycol

base anti-freeze and deionized water. Cooling system

capacity is listed in the specifications. Use only deion-

ized 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 chro-

mium hydroxide (“green slime”) forms and will

cause overheating. Engines that have been oper-

ated 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. The manufacturer also recommends

that any soluble oil inhibitor is NOT used for this

equipment.

DANGER

 Do not remove the radiator pressure cap while

the engine is hot or serious burns from boiling

liquid or steam could result.

 Ethylene glycol base antifreeze is poisonous.

Do not use mouth to siphon coolant from the

radiator, recovery bottle or any container. Wash

hands thoroughly after handling. Never store

used antifreeze in an open container because

animals are attracted to the smell and taste of

antifreeze even though it is poisonous to them.

Temperature Oil Grade (Recommended)

Above 80° F (27° C) SAE 30W or 15W-40

32° to 80° F (0° to 27° C) SAE 20W-20 or 15W-40

Below 32° F (0° C) See Note

Equipment Description

Equip002 Rev. 0 08/05

ENGINE PROTECTIVE DEVICES

The standby generator may be required to operate for

long periods of time without an operator on hand to

monitor such engine conditions as coolant tempera-

ture, oil pressure or rpm. For that reason, the engine

has several devices designed to protect it against

potentially damaging conditions by automatically

shutting down the unit when the oil pressure is too

low, the coolant temperature is too high, the coolant

level is too low, or the engine is running too fast.

NOTE:

Engine protective switches and sensors are men-

tioned here for the reader’s convenience. Also

refer to the applicable control panel manual for

additional automatic engine shutdown informa-

tion.

HIGH COOLANT TEMPERATURE SWITCH

This switches contacts close if the temperature should

exceed approximately 140° C (284° F), initiating an

engine shutdown. The generator will automatically

restart and the LED will reset once the temperature

has returned to a safe operating level.

LOW COOLANT LEVEL SENSOR

Should the engine coolant level drop below the level

of the high coolant temperature switch, it is possible

for the engine to overheat without automatic shut-

down. To prevent such overheating, the engine has a

low coolant level sensor. If the level of engine coolant

drops below the level of the low coolant level sensor,

the engine automatically shuts down.

LOW OIL PRESSURE SWITCH

This switch has normally closed contacts that are

held open by engine oil pressure during cranking and

operating. Should oil pressure drop below the 8 psi

range, switch contacts close, and the engine shuts

down. The unit should not be restarted until oil is

added, and the AUTO/OFF/MANUAL switch must be

turned to OFF and then back to AUTO.







OVERCRANK SHUTDOWN

After a prespecified duration of cranking, this func-

tion ends the cranking if the engine has failed to

start. The overcrank LED will turn ON. Turn OFF the

AUTO/OFF/MANUAL switch, then turn switch back to

AUTO to reset the generator control board.

NOTE:

If the fault is not corrected, the overcrank feature

will continue to activate.

Approximate Crank Cycle Times

• 15 seconds ON

• 7 seconds OFF

• 7 seconds ON

• 7 seconds OFF

• Repeat for 45 seconds

Approximately 90 seconds total.

OVERSPEED SHUTDOWN

A speed circuit controls engine cranking, start-up,

operation and shutdown. Engine speed signals are

delivered to the circuit board whenever the unit is

running. Should the engine overspeed above a safe,

preset value, the circuit board initiates an automatic

engine shutdown. Contact the nearest Authorized

Dealer if this failure occurs.

RPM SENSOR LOSS SHUTDOWN

If the speed signal to the control panel is lost, engine

shutdown will occur.

DC FUSE

This fuse is located inside of the control panel. It

protects the panel wiring and components from

damaging overload. Always remove this fuse before

commencing work on the generator. The unit will

not start or crank if the fuse is blown. Replace the

fuse with one of the same size, type, and rating. (See

the exploded views and parts lists at the end of this

manual for replacement part number.)

FUEL SYSTEM

FUEL REQUIREMENTS

The standby generator may be equipped with one of

the following fuel systems:

• Natural gas fuel system

• Propane vapor (PV) fuel system

The Manual Drawing Listing that is affixed to the

unit includes the “Identification Code,” which may be

used to identify the type of fuel system installed on

the unit.

Recommended fuels should have a Btu content of at

least 1,000 Btus per cubic foot for natural gas; or at

least 2,520 Btus per cubic foot for LP gas. Ask the

fuel supplier for the Btu content of the fuel.

Required fuel pressure for natural gas is 5 inches

to 14 inches water column (0.18 to 0.5 psi); and

for liquid propane, 5 inches to 14 inches of water

column (0.18 to 0.5 psi).

NOTE:

Any piping used to connect the generator to the

fuel supply should be of adequate size to ensure

the fuel pressure NEVER drops below five inches

water column for natural gas or 5 inches water

column for propane vapor for all load ranges.

NOTE:

It is the responsibility of the installer to make sure

that only the correct recommended fuel is sup-

plied to the generator fuel system. Thereafter, the

owner/operator must make certain that only the

proper fuel is supplied.

NATURAL GAS FUEL SYSTEM

Natural gas is supplied in its vapor state. In most

cases, the gas distribution company provides piping

from the main gas distribution line to the standby

generator site. The following information applies to

natural gas fuel systems.

• Gas pressure in a building is usually regulated by

national, state and local codes.

• To reduce gas pressure to a safe level before

the gas enters a building, a primary regulator is

needed. The natural gas supplier may or may not

supply such a regulator.

• It is the responsibility of the gas supplier to make

sure sufficient gas pressure is available to operate

the primary regulator.

• Gas pressure at the inlet to the fuel shutoff sole-

noid should not exceed approximately 14 inches

water column (0.5 psi). Optimum pressure at the

fuel shutoff solenoid is 11 inches water column

(0.4 psi).





PROPANE VAPOR WITHDRAWAL FUEL SYSTEM

This type of system utilizes the vapors formed above

the liquid fuel in the supply tank. Approximately 10

to 20 percent of the tank capacity is needed for fuel

expansion from the liquid to the vapor state. The

vapor withdrawal system is generally best suited for

smaller engines that require less fuel. The installer

should be aware of the following:

• The natural gas and LP gas systems are similar.

However, the natural gas system delivers gas at a

pressure of approximately five inches water col-

umn to the carburetor.

• When ambient temperatures are low and engine

fuel consumption is high, the vapor withdrawal

system may not function efficiently.

• Ambient temperatures around the supply tank

must be high enough to sustain adequate vaporiza-

tion, or the system will not deliver the needed fuel

volume.

• In addition to the cooling effects of ambient air, the

vaporization process itself provides an additional

cooling effect.

LP FUEL SYSTEM

LP is supplied as a liquid in pressure tanks. It is

usually made up of propane, butane, or a mixture of

the two gases. Propane tends to vaporize readily even

at temperatures as low as -20° F (-29° C). However,

butane reverts to its liquid state when temperatures

drop below 32° F (0° C).

LP in a liquid withdrawal system must be converted

to its gaseous state before it is introduced into the

engine carburetor. A vaporizer-converter is generally

used to accomplish this. In such a converter, heated

engine coolant is ported through the converter to

provide the necessary heat for conversion of the fuel

from a liquid to a gaseous state.

GENERATOR AC LEAD CONNECTIONS

See “Voltage Codes”. This generator may be rated

at any one of three voltages, either single-phase or

three-phase. The electrical wires in the unit’s AC con-

nection (lower) panel should be installed according to

the number of leads and the voltage/phase required

for the application. If there are any questions regard-

ing lead connection, refer to the wiring diagrams at

the back of this manual.

Voltage codes apply to the type of stator assembly

installed on a particular generator.

FOUR-LEAD, SINGLE-PHASE STATOR

Four-lead generators (see Figure 7.1) are designed to

supply electrical loads with voltage code “A” (240V,

1-phase, 60 Hz). Electrical power is produced in the

stator power windings. These windings were con-

nected at the factory to the main circuit breaker as

shown in Figure 7.1.

The rated voltage between each circuit breaker ter-

minal is 240V. The rated voltage between each circuit

breaker terminal and the neutral point 00 is 120V.

Figure 7.1 — Four-lead, Single-phase Stator



ALTERNATOR POWER WINDING

CONNECTIONS

3-PHASE ALTERNATORS

The generator is designed to supply 3-phase electri-

cal loads. Electric power is produced in the alterna-

tor power windings. These windings were connected

at the factory to the main circuit breaker with a “Y”

configuration as shown in Figures 7.2 and 7.3.

The rated voltage between circuit breaker terminals

E1-E2, E1-E3 and E2-E3 is either 480V or 208V

INSTALLATION

Refer to the separate “Installation Guide QT Product

Line” supplied with the unit.

PREPARATION BEFORE START-UP

The instructions in this section assume that the

standby generator has been properly installed, ser-

viced, tested, adjusted and otherwise prepared for

use by a competent, qualified installation contractor.

Be sure to read the “Safety Rules”, as well as all other

safety information in this manual, before attempting

to operate this (and related) equipment.

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 the “Maintenance” section

and the “Service Schedule”.

TRANSFER SWITCH

If this generator is used to supply power to any elec-

trical system normally powered by an electric utility,

the National Electrical Code requires that a transfer

switch be installed. The transfer switch prevents elec-

trical backfeed between two different electrical sys-

tems. (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.

FUEL SYSTEM

Make sure the fuel supply system to the genera-

tor (a) delivers the correct fuel at the correct pres-

sure and (b) is properly purged and leak tested

according to code. No fuel leakage is permitted. See

“Specifications” for more information.

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”

and “Engine Oil Recommendations”.

NOTE:

This engine is shipped from the manufacturer

with “break-in” oil. This oil should be changed

after 30 hours of operation.

Check the oil level in the generator gearbox (if so

equipped) prior to initial use and at the intervals

indicated by the “Service Schedule.” The recom-

mended oil is SAE 90 gear lubricant.

Also, if the engine is equipped with a mechanical gov-

ernor, make sure the governor is properly lubricated

with clean engine oil.







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.

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” sections.



COOLING SYSTEM

Air intake and outlet openings in the generator com-

partment must be open and unobstructed for contin-

ued proper operation. This includes such obstruc-

tions as high grass, weeds, brush, leaves and snow.

Without sufficient cooling and ventilating air flow, the

engine/generator quickly overheats, which causes it

to shut down. (See the installation diagram.)

 The exhaust system parts from this product get

extremely hot and remains hot after shutdown.

High grass, weeds, brush, leaves, etc. must

remain clear of the exhaust. Such materials may

ignite and burn from the heat of the exhaust

system.

OVERLOAD PROTECTION FOR ENGINE

DC ELECTRICAL SYSTEM

Engine cranking, start up and running are controlled

by a solid state Engine Controller circuit board.

Battery voltage is delivered to that circuit board via

a 15 amp fuse. These overcurrent protection devices

will open if the circuit is overloaded.

 If a circuit breaker opens or a fuse element

melts, find the cause of the overload before

resetting the circuit breaker or replacing the

fuse.

CHECKING FLUID LEVELS

CHECK ENGINE OIL

Check engine crankcase oil level (Figure 10.1) at least

every 20 hours of operation, or prior to use.

• Remove oil dipstick and wipe dry with a clean, lint-

free cloth.

• Install oil dipstick, then remove again.

• Oil should be between FULL and ADD marks.

• If oil level is below the dipstick ADD mark, remove

oil fill cap-. Add the recommended oil to bring oil

level up to the FULL mark. DO NOT FILL ABOVE

THE “FULL” MARK. See “Engine Oil Recommen-

dations” for recommended oils.

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 10.4).

MISCELLANEOUS MAINTENANCE

CLEANING THE GENERATOR

Keep the generator as clean and as dry as possible.

Dirt and moisture that accumulates on internal gen-

erator windings have an adverse effect on insulation

resistance.

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.

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 bat-

tery 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.

BATTERY MAINTENANCE

The battery should be inspected per Section 4.7,

Scheduled Maintenance. 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 bat-

tery hydrometer.

DANGER

 Storage batteries give off explosive hydrogen

gas. This gas can form an explosive mixture

around the battery for several hours after charg-

ing. The slightest spark can ignite the gas and

cause an explosion. Such an explosion can shat-

ter the battery and cause blindness or other

injury. Any area that houses a storage battery

must be properly ventilated. Do not allow smok-

ing, open flame, sparks or any spark producing

tools or equipment near the battery.

 Battery electrolyte fluid is an extremely corro-

sive 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.

 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 120VAC power supply to the battery

is turned OFF, or sparking may occur at the bat-

tery posts as the cables are attached and cause

an explosion.

BATTERY REPLACEMENT

When replacing batteries, use the same number and

the type of battery that follows:

NOTE:

The BCI number should be located directly on the

battery.

SERVICE SCHEDULE

The following is a recommended maintenance schedule for small standby and residential generator sets. The

established intervals in the schedule are the maximum recommended when the unit is used in an average service

application. They will need to be decreased (performed more frequently) if the unit is used in a severe applica-

tion. Use calendar time or accumulated run time, from the previous maintenance interval to determine the next

required maintenance interval.

Service Maintenance Interval Information:

The various service maintenance intervals are designated by interval numbers as follows:

1 An early inspection of the generator set to insure it is ready to operate when required and to identify any poten-

tial problem areas.

Performed monthly this requires approximately .5 man-hours per unit to complete.

This inspection may be performed by the end user providing the following safety steps are taken to prevent

the engine from starting automatically without warning:

To prevent injury, perform the following steps in the order indicated before starting any maintenance:

• Disable the generator set from starting and/or connecting to the load by setting the control panel

AUTO/OFF/MANUAL switch to the OFF position.

• Remove the 5 amp and 15 amp control panel fuses.

• Turn off the battery charger (turn OFF utility supply to ATS).

• 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 30 run time 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 Service 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 this 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 Service 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 this requires approximately 4.0 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 Service Dealer.
