Section 1: Safety Information
Introduction
Thank you for purchasing this compact, high
performance, air-cooled, engine-driven gen-
erator. It is designed to automatically supply
electrical power to operate critical loads
during a utility power failure.
This unit is factory installed in an all-weather,
metal enclosure intended exclusively for out-
door installation. This generator will operate
using either vapor withdrawn liquid propane
(LP) or natural gas (NG).
NOTE: This generator is suitable for supplying
typical residential loads such as induction
motors (sump pumps, refrigerators, air condi-
tioners, furnaces, etc.), electronic components
(computer, monitor, TV, etc.), lighting loads,
and microwaves, when sized correctly. This
unit is equipped with a Wi-Fi® module, which
allows the generator owner to monitor genera-
tor status from anywhere they have Internet
access.
NOTE: Wi-Fi® is a registered trademark of Wi-
Fi Alliance®.
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,
