Use this page to record important information about your generator set.

Record the information found on your unit data label on this

page. For the location of the unit data label, see your owner’s

manual. The unit has a label plate affixed to the inside parti-

tion, to the left of the control panel console.

When contacting an Independent Authorized Service Dealer

(IASD) about parts and service, always supply the complete

model and serial numbers of the unit.

Operation and Maintenance: Proper maintenance and care

of the generator ensures a minimum number of problems

and keeps operating expenses at a minimum. It is the

operator’s responsibility to perform all safety checks, to

make sure that all maintenance for safe operation is

performed promptly, and to have the equipment checked

periodically by an IASD. Normal maintenance, service, and

replacement of parts are the responsibility of the owner/

operator and are not considered defects in materials or

workmanship within the terms of the warranty. Individual

operating habits and usage may contribute to the need for

additional maintenance or service.

When the generator requires servicing or repairs, Generac

recommends contacting an Independent Authorized Service

Dealer for assistance. To locate the nearest Independent

Authorized Service Dealer, please visit the dealer locator at:

Section 1: Safety Rules & General Information

Introduction

Thank you for purchasing this compact, high-

performance, variable speed, air-cooled, engine-driven

stationary automatic standby generator set. Every effort

has been made to ensure that the information and

instructions in this manual are both accurate and

complete at the time of release. However, the

manufacturer reserves the right to change, alter, or

otherwise improve this product at any time without prior

notice.

In off–grid applications as a part of an alternative energy

system, the generator starts when the inverter/battery

charger detects the normal power source voltage has

dropped below a preset level. The generator powers the

inverter and, once the voltage level of the battery rises to

an acceptable level, the generator is shut down. Another

off–grid application would be for use in remote locations

such as for pumping water for a village or campground,

or for livestock.

The unit is factory installed in an all–weather metal

enclosure and is intended for outdoor installation

only. The generator can be operated using either natural

gas (NG) or vapor withdrawn liquid propane (LP).

NOTE: When properly sized, this generator is suitable

for supplying typical residential loads such as induction

motors (sump pumps, refrigerators, air conditioners,

furnaces, etc.), electronic components (computer,

monitor, TV, etc.), lighting loads and microwaves, or

loads less than 10 kW or 2 hp.

The information in this manual is accurate based on

products produced at the time of publication. The

manufacturer reserves the right to make technical

updates, corrections, and product revisions at any time

without notice.

Read This Manual Thoroughly

If any portion of this manual is not understood, contact

the nearest Independent Authorized Service Dealer

(IASD) for starting, operating, and servicing procedures.

This manual must be used in conjunction with the

appropriate owner’s manual.

SAVE THESE INSTRUCTIONS: The manufacturer

suggests that this manual and the rules for safe operation

be copied and posted near the unit installation site.

Safety should be stressed to all operators and potential

operators of this equipment.

Throughout this publication and on tags and decals

affixed to the generator, DANGER, WARNING, and

CAUTION blocks are used to alert personnel to special

instructions about a particular operation that may be

hazardous if performed incorrectly or carelessly. Observe

them carefully. Their definitions are as follows:

NOTE: Notes provide additional information important to

a procedure or component.

Safety alerts cannot eliminate the hazards they indicate.

Observing safety precautions and strict compliance with

the special instructions while performing the action or

service are essential to preventing accidents.

The operator is responsible for proper and safe use of

the equipment. The manufacturer strongly recommends

that if the operator is also the owner, to read the owner’s

manual and thoroughly understand all instructions before

using this equipment. The manufacturer also strongly

recommends instructing other users to properly start and

operate the unit. This prepares them if they need to

operate the equipment in an emergency.

How to Obtain Service

When the generator requires servicing or repairs, contact

an IASD for assistance. Service technicians are factory-

trained and are capable of handling all service needs.

Please visit the dealer locater at: www.generac.com/

Service/DealerLocator/ to locate the nearest IASD.

Safety Rules & General Information

2Installation Guidelines For 60 Hz EcoGen™ Generators

When contacting an IASD about parts and service,

always supply the complete model number and serial

number of the unit as given on its data decal, which is

located on the generator. Refer to owner’s manual for

decal location. Record the model and serial numbers in

the spaces provided on the inside front cover of this

manual.

Safety Rules

Study these SAFETY RULES carefully before installing,

operating, or servicing this equipment. Become familiar

with this installation manual, the owner’s manual, and

with the unit. The generator can operate safely,

efficiently, and reliably 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 alerts in

this manual and on tags and decals affixed to the unit are

not all-inclusive. If using a procedure, work method, or

operating technique the manufacturer does not

specifically recommend, verify that it is safe for others

and does not render the generator unsafe.
