e fa
m
iliar with this
O
wner s
Manual
and with the unit. The generator can operat e safely, effi-
ciently and reliably only if it is properly installed, ope rated and
m
aintained. Many accidents are caused by failing to foll ow si
m
ple
and funda
m
ent al rules or precautions.
The
m
anufacturer cannot anticipate every possible circu
m
stance
that
m
ight involve a hazard. The wa rning s in this
m
anual, and on
tags and decals affixed to the unit are, therefore, not all-inclusive. If
using a procedure, work
m
ethod or operating technique the
m
anu-
facturer do es not specifically reco
mm
end, ensure that it is safe for
ot hers. Also
m
ake sure the procedure, work
m
ethod or operating
technique utilized does not render the generator unsafe.
DANGER
Despite the safe design of this generator,
operating this equipment imprudently, neglecting
its maintenance or being careless can cause
possible injury or death. Permit only responsible
and capable persons to install, operate and 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.
Installation must always comply with applicable
codes, standards, laws and regulations.
A running generator gives off carbon monoxide,
and odorless, colorless poison gas. Breathing in
carbon monox ide can cause headaches, fatigue,
di ziness, nausea, vomitting, confusion, fainting,
siezures or death.

IMPORTANT SAFETY INSTRUCTIONS
Air-cooled Generators
DANGER
Only qualified electricians or contractors should
attempt such installations, which must comply
strictly with applicable codes, standards and regu-
l ations.
1.1 UNPACKING/INSPECTION
After unpacking, carefully inspect the contents for d a
m
age.
This standby generator set is ready for installation with a factory
supplied and pre-
m
ounted base pad and h as a weather protec-
tive enclosure that is intended for outdoor installation only.
If this generat or is used to power electrical load
circuits normally powered by a utility power
source, it i s required by code to install a transfer
switch. The transfer switch must effectively isolate
the electrical system from the utility distribution
system when the generator is operating (NEC 700,
701 & 702). Failure to isolate an electrical system
by such means will result i n damage to the gen-
erator and also may result in injury or death to
utility power workers due to backfeed of electrical
energy.

1.3 NEC REQUIREMENT FOR ARC FAULT
CIRCUIT INTERRUPTION BREAKER FOR
BEDROOMS
In 2001, the
N
ational Electric Code
(
N
EC
)
introduced a require
m
ent
for new construct ion. This new require
m
ent indicates the nee d for
Arc Fault Circuit Interrupters to be used to protect the co
m
plete
branch circuit that feeds a dwelling bedroo
m
. The actual
N
EC
require
m
ent is ind icate d b elow.
1.3.1 SECTION 210.12 ARC FAULT CIRCUIT INTER-
RUPTER PROTECTION
1.
D
efinition: An arc fault circ uit i nterrupt er is a device intended
to provide protection fro
m
the effects of arc fault s by recog-
nizing characteristics unique to arcing and by functioning to
de-energize the circuit when an arc fault is detected.
2.
D
welling
U
nit Bedroo
m
s: All branch circuits that supply 125
volt , single-phase, 15 and 20 a
m
pere outlets installed in
dwelling unit bedroo
m
s shall be protected by an arc fault cir-
c uit interrupter listed to provi de protection of the entire branch
cir cuit.
S
ection 210.12 requires that AFCI protect ion be provided on branch
cir cuits that supply outlets
(
receptacle, lighting, etc.
)
in dwell-
ing bedroo
m
s. The require
m
ent is li
m
ited to 15 and 20 a
m
pere,
125 volt circuit s. There is no prohibition against providing AFCI
protection on other circuits or in locations oth er than b edroo
m
s.
Because circuits are often shared between a bedroo
m
and other
areas such as closets and hallways, providing AFCI protection on
the co
m
plete circuit would co
m
ply with 210.12.
If during the installation of the ho
m
e standby syste
m
the decision
is
m
ade to provi de back up power to a bedroo
m
branch circuit,
then the circuit breaker in the transfer switch should be replaced
with an Arc Fault Circui t Int errupter.
It is
m
ost i
m
por tant that breakers only be switched like for like.
For instance, if replacing a 15A breaker, it M
U
S
T be replaced wi th
a 15A AFCI breaker.
L
ikewise, a 20A breaker M
U
S
T be replaced
with a 20A AF CI.
These AFCI breakers are available at the nearest hardware store.

1.8 FUEL REQUIREMENTS
AND RECOMMENDATIONS
With LP gas, use only the vapor withdrawal system. This type of
syste
m
uses the vapors for
m
ed above the liquid fuel in t he storage
tank.
The engine has been fitted with a fuel carburetion syste
m
th at
m
eets the specifications of the 1997 California Air
R
esources
Board for ta
m
per-proof du al fuel syste
m
s. Th e unit will run on
natural ga s or
L
P gas, but it has been factory set to run on natural
gas.
S
hould the pri
m
ary fuel need to be changed to
L
P gas, the
fuel syste
m
needs to be reconfigured.

ended 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
c ubic foot for
L
P ga s. Ask the fuel supplier for the Btu content of
the fuel.
R
eq uired fuel pressure for natural gas is five (5) inches to seven
(7) inches water column (0.18 to 0.25 psi); and for liquid pro-
pane, 10 inches to 12 inches of water column (0.36 to 0.43 psi).
The primary regulator for the propane supply is NOT INCLUDED
with the generator.
NOTE:
All pipe sizing, construction and layout must comply
with NFPA 54 for natural gas applications and NFPA
58 for liquid propane applications. Once the genera-
t or is installed, verify that the fuel pressure NEVER
drops below four (4) inches w ater column for natural
gas or 10 inches water column for liquid propane.
Prior to install ation of the generator, the installer should consult
loca l fuel suppliers or the fire
m
arshal to check codes and regula-
tions for proper installation.
L
ocal codes will
m
andate correct rout-
ing of gaseous fuel line piping around gardens, shrubs and other
landscaping to prevent any d a
m
age.
S
pecial considerations should be given when installing the unit
where local conditions include flooding, torn ados, hurricanes,
ear thquakes a nd unstable ground for the flexibility and strength of
piping and their connecti ons.
U
se an approved pipe sealant or joint co
m
pound on all threaded
fitting.
All installed gaseous fuel piping
m
ust be purged and leak tested
pri or to initial star t-up in accord ance with local codes, standards
and regulations.

DANGER
Gaseous fuels such as natural gas and liquid
propane (LP) 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 settl e in low areas.
NOTE:
A minimum of one approved manual shut-off valve
must be installed in the gaseous fuel supply line. The
valve must be easily accessible. Local codes deter-
mine the proper location.

DANGER
The engine exhaust fumes contain carbon mon-
ox ide, whi ch can be DEADLY. This dangerous
gas, if breathed in sufficient concentrations,
can cause unconsciousness or even death. This
generator must be instal led properly, in strict
compliance with applicable codes and stan-
dards. Following installation, do nothing that
might render the system unsafe or in noncom-
pliance with such codes and standards.
Operate the generator outdoors ONLY.
Keep exhaust gases from ent ering a confined
area through windows, doors, ventilation, crawl
spaces or other openings (Figure 1.9).
Generac Power Systems as a responsible manu-
facturer highly recommends that carbon monox-
ide detector(s) be installed indoors according to
the manufacturer
'
s instructions/recommendations.
The generator must me mounted safely per appli-
cable codes and the manufacturer
'
s specifica-
tions. Do NOT alter or add to the exhaust syst em,
or do anything that might render the exhaust sys-
tem unsafe or in noncompliance with applicable
codes and standards.

m
eans
of full scale fire test or by calculation procedures.
Because of the li
m
ited spaces that are freque ntly available for

ind, the
m
anufacturer contracted with an inde pendent
testing laboratory to run full sca le fire tests to assure that the
Eaton enclosure woul d not ignite co
m
bustible
m
aterials outside
the enclosure.
The criteria was to d eter
m
ine the worst ca se fire scenario within
the generator and to deter
m
ine the ignitability of ite
m
s outside
the engine enclosure at various distances. The Eaton enclosure
is constructed of non-co
m
bustible
m
aterials and the results and
c onclusi ons fro
m
the independent testing lab indicated that any
fire within the generator enclosure would not pose any ignition risk
to nearby co
m
bustibles or structures, with or without fire service
personnel response.
Based on this testing and the require

S
pecifications section for correct battery size and rating
If the AUTO/OFF/MANUAL switch is not set to its
OFF position, the generator can crank and start
as soon as the battery cables are connected. If
the utility pow er supply is not turned off, spark-
ing can occur at the battery posts and cause an
explosion.
1.13 BATTERY INSTALLATION
Fill the battery with the prope r electrolyte fluid if necessary and
have the battery fully charged before installing it.

Figure 1.11 Battery Cable Connections
NOTE:
Dielectric grease should be used on battery posts to
aid in the prevention of corrosi on.
NOTE:
Damage will result if battery connec ti ons are made
in reverse.
NOTE:
In areas where temperatures regularly fall below 10
°
F (-12
°
C) it is recommended that a pad type battery
heater be installed to aid in cold climate starting.
1.14 THE BATTERY
DANGER
Do not dispose of the battery in a fire. The
battery is capable of exploding.
A battery presents a risk of electrical shock
and hi gh short circuit current. The following pre-
cautions are to be observed when working on
batteries:
Remove the 7.5A fuse from the generator control
panel.
Remove watches, rings or other metal objects;
Use tools with insulated handles;
Wear rubber gloves and boots;
Do not lay tools or metal parts on top of the
battery; and
Disconnect charging source prior to connecting or
disconnecting battery terminals.
Do not open or mutilate the battery. Released
electrolyte has been known to be harmful to the
skin and eyes, and to be toxic.
The electrolyte is a dilute sul furic 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 prot ective clothing;
Where electrolyte contacts the skin, wash it off
immediately with water;
Where electrolyte contacts the eyes, flush thor-
oughly and immediately with water and seek medi-
cal attention; and
Spilled electrolyte is to be washed down wi th an
acid neutralizing agent. A common practice is to
use a solution of 1 pound (500 grams) bicarbonate
of soda to 1 gallon (4 liters) of water. The bicar-
bonate 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 fol-
lowing
procedures are to be followed:
DO NOT SMOKE when near the battery;
DO NOT cause flame or spark i n battery area; and
Discharge static electricity from body before
t ouching the battery by first touching a grounded
metal surface.
Section 1 General Information
Air-cooled Generators

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
and the 7.5A fuse is removed from the generator
control panel, or sparking may occur at the bat-
tery posts as the cables are attached and cause
an explosion.
S
ervicing of the battery is to be per for
m
ed or supervised by per-
sonnel knowledgeable o f batteries and the required precautions.
Keep unauthorized personnel away fro

1.15 BATTERY CHARGER
NOTE:
These generators DO NOT contain an internal battery
charger.
NOTE:
The manufacturer provides a battery trickle charger
that is active when the unit is set up for automatic
operation. With the battery installed and ut ility power
source voltage available to the transfer switch, the
battery recei ves a trickle charge to prevent self-
discharge. The trickle charger is designed to help
extend the life of the battery by maint aining the bat-
tery. The trickle charge feature cannot be used to
recharge a discharged battery.
A separate bat tery charger
m
odule is included with the generator.

With the switch set to AUTO, the engine may
crank and start at any time without warning.
Such automati c starting occurs when utility
power source voltage droops below a preset
level or during the normal exercise cycle. To
prevent possible injury that might be c aused
by such sudden starts, always set t he switch to
OFF and remove the fuses before working on or
around the generator or transfer switch. Then,
place a DO NOT OPERATE tag on the genera-
t or panel and on the transfer switch.
