Operation

1.1 HOW TO USE THE GENERATOR

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.

1.1.1 SYSTEM GROUND

The generator has a system ground that connects the generator
frame components to the ground terminals on the AC output
receptacles.
This generator system ground IS bonded to the neutral in the
generator (see applicable unit wiring diagram).
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:

NOTE:
• 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.
Connecting to a Building's Electrical System through a
Transfer Switch
IMPORTANT: Connections for standby power to a building's
electrical system must be made by a qualified electrician. The
connection must isolate the generator power from utility power, or
other alternative power sources, and must comply with all related
laws and codes.
This generator system ground IS bonded to the neutral in the
generator (see applicable unit wiring diagram).

1.1.2 GROUNDING THE GENERATOR

Local electrical codes may require proper grounding of the unit. For
that purpose, connecting a No. 10 AWG (American Wire Gauge)
stranded copper wire to the grounding lug and to an earth-driven
copper or brass grounding rod (electrode) provides adequate
protection against electrical shock. However, local codes may vary
widely. Consult with a local electrician for grounding requirements
in the area. Proper grounding of the generator will help prevent
electrical shock in the event of a ground fault condition in the
generator or in connected electrical devices. Proper grounding
also helps dissipate static electricity, which often builds up in
ungrounded devices.

1.1.3 CONNECTING ELECTRICAL LOADS

DO NOT connect 240 Volt loads to 120 Volt receptacles. DO NOT
connect 3-phase loads to the generator. DO NOT connect 50 Hz
loads to the generator.
• Let engine stabilize and warm up for a few minutes after
starting.
