Section 1: Safety Information
Introduction
Thank you for purchasing this compact, high
performance, air-cooled, engine-driven generator. 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 outdoor 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This generator will operate using either vapor withdrawn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 conditioners, furnaces, etc.), electronic
components (computer, monitor, TV, etc.), lighting loads,
and microwaves, when sized properly. This unit is
equipped with a Wi-Fi® module, which enables the
generator owner to monitor generator status from
anywhere he or she has 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, and product revisions at any time
without notice.
