operated and maintained. Many accidents are caused by failing to follow
simple and fundamental rules or precautions.
CARRIER cannot possibly 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 you use a procedure, work method
or operating technique not specifically recommended, you must satisfy
yourself that it is safe for you and others. You also must make sure the
procedure, work method or operating technique that you choose does not
render the generator unsafe.
The product contains or emits chemicals known to the state of
California to cause cancer, birth defects or other reproductive
harm.

potential operators of this equipment.
The engine exhaust from this product contains chemicais known
to the state of California to cause cancer, birth defects or other
reproductive harm.
• When working on this equipment, remain alert at all times. Never work on
the equipment when you are physically or mentally fatigued.
• Inspect the generator regularly, and contact your nearest CARRIER
Dealer for parts needing repair or replacement.
• Before performing any maintenance on the generator, disconnect its
battery cables to prevent accidental start up. Disconnect the cable from
the battery post indicated by a NEGATIVE, NEG or (-) first. Reconnect that
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.
A
ELECTRICAL HAZARD
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 operation. Avoid contact with bare
wires, terminals, connections, 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
insulated, 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.
A
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 the home standby electrical system has been installed it will be
capable of cranking and starting at any time while in the "Auto" mode.
When the unit starts in "Auto” the load circuits are transferred to the
STANDBY (generator) power source. To prevent possible injury when working
on the system

FIRE
PRE-PACKAGED COMPONENTS INCLUDES;
or
In case of accident caused by electric shock, immediately shut down the
source of electrical power. If this is not possible, attempt to tree the
victim from the live conductor.
Use a non-conducting 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 equipment. Jewelry can
conduct electricity resulting in electric shock, or may get caught in
moving components causing injury.
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 installation, do nothing that
might alter a safe installation 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 electric system. Keep the extinguisher properly
charged and be familiar with its use. It you have any question pertaining
to fire extinguishers, consult your local fire department.
AVOID DIRECT CONTACT WITH THE VICTIM.

SITE PREPARATION
1. It will be necessary to pay a visit to your local municipal offices
to apply for a building permit. Building permits are necessary to
ensure proper installation, safety and adherence to all local
building code specifications. The location and phone number
can be found in the government section of your local phone book.
2. Plan the location of your generator.
generator directly under a window.
your home nearest your incoming gas service.
3. Arrange for installation of rigid gas piping (per local code
specifications) to the location where you intend to position your
generator. Fuel piping should include a fuel shut-off valve. The
termination of the rigid piping should be aligned with the
generator fuel inlet located at the rear of the compartment.
4. Clear an area 5-1/2 feet by 5 feet minimum of grass and vegetation
to a depth of 5 inches. This includes the distance the generator
should be set away from any structure (3 feet) and 6 inches beyond
the width and length of the generator mounting pad (48” Lx24” W).
NOTE: Local codes may supercede these requirements.
5. Lay black poly-film to cover the area.
6. Fill the area to ground level with pea gravel or crushed stone.
7. Place the generator, which is attached to the mounting pad, on
the area you have just prepared.
‘ 8a. Drive an 8 ft. grounding rod into the ground to grade.

Attach one end of the grounding strap (No. 12 AWG stranded
copper wire) to grounding rod and the other end to the grounding
lug (located at rear corner of unit). Make sure grounding rod and
strap are not exposed above ground level. (NEC code applies to
grounding method.)
NOTE: Generator mode switch should be placed in the “off”
