Use this page to record important information about this generator set.
R
ecord the information found on the unit data label on this
page. See
Safety and Informational Decals for the location
of the unit data label. The unit has a label plate affixed to the
inside partition as shown in
Figure 1-1 . See Enclosure Panel
Removal
for directions on how to open the top lid and remove
the front panel
.
Always supply the complete model and serial numbers of the
unit when contacting an Independent Authorized Service
Dealer (IASD) about parts and service.
Operation and Maintenance: Correct maintenance and
care of the unit ensures a minimum number of problems, and
keeps operating expenses at a minimum. It is the operator’s
responsibility to perform all safety inspections, to verify all
maintenance for safe operation is performed promptly, and
to have the equipment inspected periodically by an IASD.
Normal maintenance, service, and replacement of parts are
the responsibility of the owner/operator and are not consid-
ered defects in materials or workmanship within the terms of
the warranty. Individual operating habits and usage may con-
tribute to the need for additional maintenance or service.
When the generator set requires servicing or repairs, Gen-
erac recommends contacting an IASD for assistance. Autho-
rized service technicians are factory-trained and are capable
of handling all service needs. To locate the nearest IASD,
please visit the dealer locator at:

Section 1: Safety Information
Introduction
Thank you for purchasing this compact, high perfor-
mance, air-cooled, engine-driven generator set. It is
designed to automatically supply electrical power to oper-
ate 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 with-
drawn liquid propane (liquid propane gas [LPG]) or natu-
ral gas (NG). See Fuel Requirements and
Recommendations.
NOTE: This generator set is intended to be used for sup-
plying 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 cor-
rectly.
This unit is also equipped with a Wi-Fi®module, which
enables the owner to monitor generator set status from
anywhere they have Internet access.
NOTE: Wi-Fi®is a registered trademark of Wi-Fi Alli-
ance®.
The information in this manual is accurate based on
products produced at the time of publication. The manu-
facturer reserves the right to make technical updates,
