2.4 HOW TO USE THE GENERATOR

See the "To Start the Engine" section for how to safely start and
stop the generator and how to connect and disconnect loads. If
there are any problems operating the generator, please call the
generator helpline at 1-888-436-3722.
Never operate in an enclosed area or indoors!

NEVER use in the home, in a vehicle, or in
partly enclosed areas such as garages, EVEN
IF doors and windows are open! ONLY use
outdoors and far from open windows, doors,
vents, and in an area that will not accumulate
deadly exhaust.
The engine exhaust fumes contain carbon
monoxide, which you cannot see or smell.
This poisonous gas, if breathed in sufficient
concentrations, can cause unconsciousness or
even death.
Adequate, unobstructed flow of cooling and
ventilating air is critical to correct generator
operation. Do not alter the installation or permit
even partial blockage of ventilation provisions,
as this can seriously affect safe operation
of the generator. The generator MUST be
operated outdoors.
This exhaust system must be properly
maintained. Do nothing that might render the
exhaust system unsafe or in noncompliance
with any local codes and/or standards.
Always use a battery operated carbon
monoxide alarm indoors, installed according to
the manufacturer's instructions.
2.4.1 GROUNDING THE GENERATOR WHEN USED AS A
PORTABLE
This generator has an equipment ground that connects the
generator frame components to the ground terminals on the AC
output receptacles (see NEC 250.34 (A) for explanation). This
allows the generator to be used as a portable without grounding
the frame of the generator as specified in NEC 250.34.
Special Requirements
There may be Federal or State Occupational Safety and Health
Administration (OSHA) regulations, local codes, or ordinances that
apply to the intended use of the generator.
Please consult a qualified electrician, electrical inspector, or the
local agency having jurisdiction:
• In some areas, generators are required to be registered with
local utility companies.
• If the generator is used at a construction site, there may be
additional regulations which must be observed.
2.4.2 CONNECTING THE GENERATOR TO A BUILDING'S
ELECTRICAL SYSTEM
Connections for standby power to a building's electrical system
must be made by a qualified electrician and in strict compliance
with all national and local electrical codes and laws. The
connection must isolate the generator power from utility power or
other alternative power sources.
Because the generator equipment ground is bonded to the AC
neutral wires in the generator, either a 3-pole transfer switch or
a 2 pole transfer switch with a switching neutral kit is required
to connect this generator to a building load. In this application
the generator becomes a separately derived system (see NEC
250.20 (D)), and must be grounded in accordance with the
national or local electrical code requirements.
