IMPORTANT SAFETY INSTRUCTIONS

SAFETY MESSAGES

This guide contains many important safety messages. Always read and obey all safety messages.

This is the safety alert symbol. It alerts you to safety messages that inform you
of hazards that can kill or hurt you or others, or cause damage to the product.

All safety messages will be preceded by the safety alert symbol and the hazard
signal word DANGER, WARNING, CAUTION. These words mean:

WARNING

You can be killed or seriously injured if you donÕt follow instructions.

CAUTION

All safety messages will identify the hazard, tell you how to reduce the chance of injury and tell you what can happen if
the instructions are not followed.

Indicates an imminently hazardous situation which, if not avoided,

may result in minor or moderate injury, or product damage only.

WARNING

To reduce the risk of fire, electric shock, or injury
to persons when using your product, basic safety
precautions should be followed, including the following:

NEVER unplug your refrigerator by pulling on the power cord.
Always grip the plug firmly and pull it straight out from the
outlet.

Repair or replace immediately all electric service cords that
have become frayed or otherwise damaged. Do not use a cord
that shows cracks or abrasion damage along its length or at
either the plug or connector end.

When moving your refrigerator away from the wall,
be careful not to roll over or damage the power cord.

DO NOTsto re or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.

DO NOTallow children to climb, stand or hang on the
refrigerator doors or shelves in the refrigerator. They could
damage the refrigerator and seriously injure themselves.

Keep fingers out of “pinch point” areas; clearances between
the doors and cabinet are necessarily small. Be careful
when you open the doors when children are in the area.

Unplug your refrigerator before cleaning or making any repairs.
NOTE: We strongly recommend that any servicing be

performed by a qualified individual.

Before replacing a burned-out light bulb, unplug the
refrigerator or turn off power at the circuit breaker or fuse box
in order to avoid contact with a live wire filament. (A burned­out light bulb may break when being replaced.)
either or both controls to the OFF position does not remove
power to the light circuit.

NOTE: Setting

For personal safety, this appliance must be properly grounded.
Have the wall outlet and the circuit checked by a qualified
electrician to make sure the outlet is properly grounded.

Read all instructions before using this appliance.
Use this appliance only for its intended purpose as described

in this use and care guide.
After your refrigerator is in operation, do not touch the cold

surfaces in the freezer compartment when hands are damp or
wet. Skin may adhere to the extremely cold surfaces.

In refrigerators with automatic icemakers, avoid contact with
the moving parts of the ejector mechanism, or with the heating
element that releases the cubes. DO NOT place fingers or
hands on the automatic icemaking mechanism while the
refrigerator is plugged in.

DO NOTrefre eze frozen foods which have thawed completely.
The United States Department of Agriculture in Home and
Garden Bulletin No. 69 says:

“...You may safely refreeze frozen foods that have thawed if

they still contain ice crystals or if they are still cold below
40°F (4°C).”

“...Thawed ground meats, poultry, or fish that have any off-odor
or off-color should not be refrozen and should not be eaten.
Thawed ice cream should be discarded. If the odor or color of
any food is poor or questionable, get rid of it. The food may be
dangerous to eat.”

“Even partial thawing and refreezing reduces the eating quality
of foods, particularly fruits, vegetables and prepared foods.
The eating quality of red meats is affected less than that of
many other foods. Use refrozen foods as soon as possible to
save as much of their quality as you can.”

DANGER: RISK OF CHILD ENTRAPMENT

Child entrapment and suffocation are not problems of
the past. Junked or abandoned refrigerators are still
dangerous... even if they will sit for “just a few days”. If
you are getting rid of your old refrigerator, please follow
the instructions at right to help prevent accidents.

BEFORE YOU THROW AWAY
YOUR OLD REFRIGERATOR
OR FREEZER

Take off the doors.

Leave the shelves in place so that
children may not easily climb inside.

CFC DISPOSAL

Your old refrigerator may have a cooling system that used If you are throwing away your old refrigerator, make sure
CFCs (chlorofluorocarbons). CFCs are believed to harm the CFC refrigerant is removed for proper disposal by a
stratospheric ozone. qualified servicer. If you intentionally release this CFC

refrigerant, you can be subject to fines and imprisonment
under provisions of environmental legislation.

GROUNDING REQUIREMENTS

IMPORTANT:

Please read carefully.

TO CONNECT ELECTRICITY

WARNING

Electrical Shock Hazard

FOR PERSONAL SAFETY, this appliance must be

properly grounded. Have the wall outlet and the
circuit checked by a qualified electrician to make sure
the outlet is properly grounded.

3-prong

Use a receptacle which cannot be turned off with a switch
or pull chain. Do not use an extension cord.

Where a standard two-prong wall outlet is encountered,
it is your personal responsibility and obligation to have it
replaced with a properly grounded three-prong wall outlet.

Do not, under any circumstances, cut or remove the
third (ground) prong from the power cord.

NOTE: Before performing any type of installation,
cleaning, or removing a light bulb, turn the control
(Thermostat, Refrigerator Control or Freezer Control,
depending on the model) to OFF and then disconnect the
refrigerator from the electrical source. When you are
finished, reconnect the refrigerator to the electrical source
and reset the control (Thermostat, Refrigerator Control or
Freezer Control, depending on the model) to the desired

setting.

USE OF EXTENSION CORDS

Ensure proper
ground exists
before use.

RECOMMENDED GROUNDING METHOD

The refrigerator should always be plugged into its own
individual properly grounded electrical outlet rated for
115 Volts, 60 Hz, AC only, and fused at 15 or 20 amperes.
This provides the best performance and also prevents
overloading house wiring circuits which could cause a fire
hazard from overheated wires. It is recommended that a

Because of potential safety hazards under certain
conditions, we strongly recommend against the use of
an extension cord. However, if you still elect to use

an extension cord, it is absolutely necessary that it be
a UL-listed (in the United States), 3-wire grounding type
appliance extension cord having a grounding type plug
and outlet, and that the electrical rating of the cord be 15
amperes (minimum) and 120 volts.

Use of an extension cord will increase the clearance
needed for the back of the refrigerator.

screws can be turned easily by tipping the cabinet
slightly. Turn the leveling screws clockwise ( ) to
raise the unit, counterclockwise ( ) to lower it.
