Use this page to record important information about your generator set.
Record the information found on your unit data label on this
page. See General Information for the location of the unit
data label. The unit has a label plate affixed to the inside
partition, to the left of the control panel console as shown in
Figure 2-1. See Operation for directions on how to open the
top lid and remove the front panel.
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 set 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 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 set requires maintenance or service,
Generac recommends contacting an IASD for assistance.
Authorized service technicians are factory–trained and are
capable of handling maintenance and service needs. To
locate the nearest IASD, visit the dealer locator at:

Section 1: Safety Information
Introduction
Thank you for purchasing this compact, high
performance, air-cooled, engine-driven generator set. It
is designed to automatically supply electrical power to
operate critical loads during a mains (utility) power
failure.
This unit is factory installed in an all-weather, metal
enclosure intended exclusively for outdoor installation.
This generator set will operate using either vapor
withdrawn liquid propane (LPG) or natural gas (NG).
NOTE: This generator set is intended to be used 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, when
sized properly.
This unit is also equipped with a Wi-Fi® module, which
enables the owner to monitor the generator set status
from anywhere he or she has Internet access.
NOTE: Wi-Fi® is a registered trademark of Wi-Fi
Alliance®.
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 installation manual.
NOTE: SAVE THESE INSTRUCTIONS: The manufacturer
suggests 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.
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

Safety Messages
Throughout this publication and on tags and decals
affixed to the generator set, three types of safety
messages 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:
These safety messages 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 owner's manual contains important
safety information and instructions that the manufacturer
recommends owners and operators review before using
the equipment. In addition, anyone who may need to
operate the generator set in an emergency outage
situation should be instructed on how to properly start
and operate the unit to be prepared for such an event.
HAZARD WARNING
Yellow triangle with black border and
black symbol; indicates a hazardous
situation which, if not avoided, could
result in death or serious injury.
MANDATORY ACTION
Blue circle with white symbol; indicates
an action required to safeguard personal
health and / or avoid causing a
hazardous situation which could result in
death or serious injury.
PROHIBITION
Red ring with diagonal bar and black
symbol; indicates a prohibited action.
Performing the prohibited action may
cause a hazardous situation which could
result in death or serious injury.
