ELECTRICAL HAZARDS

• All generators covered by this manual produce

dangerous electrical voltages and can cause fatal

electrical shock. Utility power delivers extremely

high and dangerous voltages to the transfer switch

as does the standby generator when it is in opera-

tion. Avoid contact with bare wires, terminals, con-

nections, etc., while the unit is running. Ensure all

appropriate covers, guards and barriers are in

place before operating the generator. If you must

work around an operating unit, stand on an insu-

lated, dry surface to reduce shock hazard.

• Do not handle any kind of electrical device while

standing in water, while barefoot, or while hands

or feet are wet. DANGEROUS ELECTRICAL

SHOCK MAY RESULT.

• The National Electrical Code (NEC) requires the

frame and external electrically conductive parts of

the generator to be connected to an approved earth

ground. Local electrical codes also may require

proper grounding of the generator electrical system.

• After installing this home standby electrical sys-

tem, the generator may crank and start at any time

without warning. When this occurs, load circuits

are transferred to the STANDBY (generator) power

source. To prevent possible injury if such a start

and transfer occur, always set the generator’s

Auto/Off/Manual switch to its OFF position before

working on equipment and remove the fuse.

• In case of accident caused by electric shock, imme-

diately shut down the source of electrical power. If

this is not possible, attempt to free the victim from

the live conductor. AVOID DIRECT CONTACT WITH

THE VICTIM. Use a nonconducting implement,

such as a rope or board, to free the victim from the

live conductor. If the victim is unconscious, apply

first aid and get immediate medical help.

• Never wear jewelry when working on this equip-

ment. Jewelry can conduct electricity resulting in

electric shock, or may get caught in moving com-

ponents causing injury.

FIRE HAZARDS

• For fire safety, the generator must be installed and

maintained properly. Installation always must

comply with applicable codes, standards, laws and

regulations. Adhere strictly to local, state and

national electrical and building codes. Comply

with regulations the Occupational Safety and

Health Administration (OSHA) has established.

Also, ensure that the generator is installed in

accordance with the manufacturer’s instructions

and recommendations. Following proper installa-

tion, do nothing that might alter a safe installation

and render the unit in noncompliance with the

aforementioned codes, standards, laws and regu-

lations.

• Keep a fire extinguisher near the generator at all

times. Extinguishers rated “ABC” by the National

Fire Protection Association are appropriate for use

on the standby electric system. Keep the extin-

guisher properly charged and be familiar with its

use. If you have any question pertaining to fire

extinguishers, consult your local fire department.

EXPLOSION HAZARDS

• Do not smoke around the generator. Wipe up any

fuel or oil spills immediately. Ensure that no com-

bustible materials are left in the generator com-

partment, or on or near the generator, as FIRE or

EXPLOSION may result. Keep the area surround-

ing the generator clean and free from debris.

• Gaseous fluids such as natural gas and liquid

propane (LP) gas are extremely EXPLOSIVE.

Install the fuel supply system according to applica-

ble fuel-gas codes. Before placing the home stand-

by electric system into service, fuel system lines

must be properly purged and leak tested according

to applicable code. After installation, you must

inspect the fuel system periodically for leaks. No

leakage is permitted.
