2Automatic Standby Generator Owner’s Manual

1.1 — General Safety

Study these safety rules carefully before operating or servicing this equipment. Become familiar with this Owner’s Manual and with the unit. The

generator can operate safely, efficiently and reliably only if it is properly installed, operated and maintained. Many accidents are caused by failing

to follow simple and fundamental rules or precautions.

The manufacturer cannot anticipate every possible circumstance that might involve a hazard. The warnings in this manual, and on tags and

decals affixed to the unit are, therefore, not all-inclusive. If using a procedure, work method or operating technique the manufacturer does not

specifically recommend, ensure that it is safe for personnel. Also make sure the procedure, work method or operating technique utilized does not

render the generator unsafe.

Despite the safe design of this generator, operating this equipment imprudently, neglecting its maintenance or

being careless can cause possible injury or death. Permit only responsible and capable persons to install, operate

and maintain this equipment.

Potentially lethal voltages are generated by these machines. Ensure steps are taken to make the machine safe

before attempting to work on the generator.

Parts of the generator are rotating and/or hot during operation. Exercise care near a running generator.

The installation of this generator must always comply with applicable codes, standards, laws and regulations.

A running generator gives off DEADLY carbon monoxide, an odorless, colorless, poisonous gas. Breathing carbon

monoxide can cause dizziness, throbbing temples, nausea, muscular twitching, headache, vomiting, weakness,

sleepiness, inability to think clearly, fainting, unconsciousness or even death.

The control panel for this unit is intended to be operated by qualified service personnel only.

1.2 — General Safety Hazards

• For safety reasons, this equipment should only be installed, serviced and repaired by a Service Dealer or other competent, qualified electri-

cian or installation technician who is familiar with applicable codes, standards, regulations and product Installation Manual guidelines. The

operator also must comply with all such codes, standards, regulations and product Installation Manual guidelines.

• The engine exhaust fumes contain carbon monoxide, which can be DEADLY. This dangerous gas, if breathed in sufficient concentrations, can

cause unconsciousness or even death. DO NOT alter or add to the exhaust system or do anything that might render the system unsafe or in

noncompliance with applicable codes and standards.

• Install a carbon monoxide alarm indoors, according to manufacturer’s instructions/recommendations.

• Adequate, unobstructed flow of cooling and ventilating air is critical for 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 installed and

operated outdoors only.

• Keep hands, feet, clothing, etc. away from drive belts, fans, and other moving or hot parts. Never remove any drive belt or fan guard while the

unit is operating.

• When working on this equipment, remain alert at all times. Never work on the equipment when physically or mentally fatigued.

• Inspect the generator regularly, and contact the nearest Dealer for parts needing repair or replacement.

• Before performing any maintenance on the generator, remove the control panel fuse and disconnect the Negative (—) battery cable to pre-

vent accidental startup. When disconnecting battery cables always remove the NEGATIVE (NEG or “—”) cable first, then remove the

POSITVE (POS, or “+”) cable. When reconnecting the cables, connect the POSITIVE cable first, and the NEGATIVE cable last.

• Never use the generator or any of its parts as a step. Stepping on the unit can stress and break parts, and may result in dangerous operating

conditions from leaking exhaust gases, fuel leakage, oil leakage, etc.

Automatic Standby Generator Owner’s Manual 3

1.3 — Exhaust Hazards

• Generator engine exhaust contains DEADLY carbon monoxide, an odorless, colorless, poisonous gas. Breathing carbon monoxide can

cause dizziness, throbbing temples, nausea, muscular twitching, headache, vomiting, weakness, sleepiness, inability to think clearly, fainting,

unconsciousness or even death. If any carbon monoxide poisoning symptom is experienced, move into fresh air and immediately seek med-

ical attention.

• This generator is designed for OUTDOOR installation ONLY. Never operate the generator inside any garage or other enclosed space.

1.4 — Electrical Hazards

• All generators covered by this manual produce dangerous electrical voltages that 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 operation. Avoid contact with bare

wires, terminals, connections, etc. while the unit is running. Ensure all appropriate covers, guards and barriers are in place, secured and/or

locked before operating the generator. If work must be done around an operating unit, stand on an insulated, dry surface to reduce potential

shock hazard.

• Do not handle any kind of electrical device while standing in water, while barefoot, or while hands or feet are wet. DANGEROUS ELECTRI-

CAL SHOCK MAY RESULT.

• This is an Automatic Standby Generator, the generator may crank and start at any time when utility is lost. When this occurs, load circuits are

transferred to the STANDBY (generator) power source. To prevent injury, before working on this generator (for inspection, service or mainte-

nance), always put the generator into the OFF mode and remove the 7.5 Amp fuse from the generator control panel.

• In case of accident caused by electric shock, immediately 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 dry 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 equipment. Jewelry can conduct electricity resulting in electric shock, or may get caught in moving

components resulting in injury.

1.5 — Fire Hazards

• For fire safety, the generator must be installed and maintained properly. Installation MUST always comply with applicable codes, standards,

laws, regulations and product Installation Manual guidelines. 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 installation, do nothing that might alter a safe instal-

lation and render the unit in noncompliance with the aforementioned codes, standards, laws and regulations.

• 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 generator. Keep the extinguisher properly charged and be familiar with its use. Consult the local fire department with

any questions pertaining to fire extinguishers.

1.6 — Explosion Hazards

• Do not smoke around the generator. Wipe up any fuel or oil spills immediately. Ensure that no combustible materials are left in the generator

compartment, or on or near the generator as FIRE or EXPLOSION may result. Keep the area surrounding 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 appli-

cable fuel-gas codes. Before placing the home standby electric system into service, fuel system lines must be properly purged and leak

tested according to applicable code. After installation, inspect the fuel system periodically for leaks. No leakage can be permitted.

4Automatic Standby Generator Owner’s Manual

If this generator is used to power electrical load circuits normally powered by a utility power source, it is

required by code to install a transfer switch. The transfer switch must effectively isolate the electrical system

from the utility distribution system when the generator is operating (NEC 702). Failure to isolate an electrical

system by such means will result in damage to the generator and also may result in injury or death to utility

power workers due to backfeed of electrical energy.
