Safe Servicing Practices
Avoid personal injury and/or property damage by observing important Safe Servicing Practices.
Following are some limited examples of safe practices:
1. DO NOT attempt a product repair if you have any doubts as to your ability to complete the repair in a safe and
satisfactory manner.
2. Always Use The Correct Replacement Parts as indicated in the parts documentation. Substitutions may defeat
compliance with Safety Standards Set For Home Appliances.
3. Before servicing or moving an appliance:
• Remove power cord from the electrical outlet, trip circuit breaker to OFF position, or remove fuse.
• Turn off water supply for steam dryer models.
• Turn off gas supply for gas dryers.
4. Never interfere with the proper operation of any safety device.
5. Use ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE. Substitutions may defeat com-
pliance with Safety Standards Set For Home Appliances.
6. GROUNDING: The standard color coding for safety ground wires is GREEN, or GREEN with YELLOW
STRIPES. Ground leads are not to be used as current carrying conductors.
It is EXTREMELY important that the service technician reestablish all safety grounds prior to completion of
service. Failure to do so will create a hazard.
7. Prior to returning the product to service, ensure that:
• All electrical connections are correct and secure.
• All electrical leads are properly dressed and secured away from sharp edges, high temperature components, and
moving parts.
• All non-insulated electrical terminals, connectors, heaters, etc. are adequately spaced away from all metal parts
and panels.
• All safety grounds (both internal and external) are correctly and securely connected.
• All panels are properly and securely reassembled
• Gas and water supplies are turned ON if shut off prior to service.

FOR YOUR SAFETY
Do not store or use gasoline, or other flammable vapors and liquids in the vicinity of this or any other appliance.
Read product labels for flammability and other warnings.
CHILD SAFETY
• Destroy carton, plastic bags, and any exterior wrapping material immediately after the freezer is unpacked.
Children should never use these items to play. Cartons covered with rugs, bedspreads,
plastic sheets or stretch wrap may become airtight chambers, and can quickly cause suffocation.
• Remove all staples from the carton. Staples can cause severe cuts, and destroy finishes if they come in contact
with other appliances or furniture.
• An empty, discarded ice box, refrigerator, or freezer is a very dangerous attraction to children.
• Remove and discard any spacers used to secure the shelves during shipping. Small objects are a choke hazard
to children.
• Remove the door(s) of any appliance that is not in use, even if it is being discarded.
Risk of Child Entrapment
Child entrapment and suffocation are not problems of the past. Junked or abandoned refrigerators or freezers are still
dangerous – even if they will sit for “just a few days”. If you are getting rid of your old refrigerator or freezer, please follow the instructions below to help prevent accidents:
• Remove the door/lid. If your door has an electronic control panel, have it removed by a qualified technician.
• Leave shelves in place so children may not easily climb inside.
• Have the refrigerant removed by a qualified technician.

Destroy carton, plastic bags, and any exterior wrapping material immediately after the refrigerator/freezer is
unpacked. Children should never use these items for play. Cartons covered with rugs, bedspreads, plastic sheets
or stretch wrap may become air tight chambers and can quickly cause suffocation.
A child might suffocate if he crawls into the freezer to hide or play. Remove the door/lid of the
refrigerator/freezer when not in use, even if you plan to discard the freezer. Many communities have laws
requiring you to take this safety precaution.
Remove or discard any spacers used to secure the shelves during shipping. Small objects are a choke hazard to
children.
Child entrapment and suffocation are not problems of the past. Junked or abandoned refrigerators or freezers are
still dangerous– even if they will sit for “just a few days”. If you are getting rid of your old refrigerator or freezer,

Location
1. Choose a place that is near a grounded electrical
outlet. Do Not use an extension cord or an adapter
plug.
2. If possible, place the refrigerator/freezer out of
direct sunlight and away from the range, dishwasher
or other heat sources.
3. The refrigerator/freezer must be installed on a floor
that is level and strong enough to support a fully
loaded refrigerator/freezer.
4. Consider water supply availability for models
equipped with an automatic ice maker.
5. The refrigerator/freezer should be located where
surrounding temperature will not exceed 110ºF
(43ºC).
6. For ease of installation, proper air circulation and
electrical connections, see Figure 2-1 for
recommended clearances.
7. For dynamic condenser models, DO NOT block
the toe grille on the lower front of your freezer.
Sufficient air circulation is essential for the proper
operation of your freezer.
Leveling
The freezer must have all bottom corners resting firmly
on a solid floor. The floor must be strong enough to
support a fully loaded freezer.
It is VERY IMPORTANT for your freezer to be level in
order to function properly. If the freezer is not leveled
during installation, the door/lid may be misaligned and
not close or seal properly, causing cooling, frost or
moisture problems.
To Level Unit:
After discarding crating screws and wood base, use a
carpenter’s level to level the freezer from front to back.
Adjust the plastic leveling feet in front, ½ bubble higher,
so that the door closes easily when left half way open.
Figure 2-1. Installation Clearances
Figure 2-2. Leveling Unit
The exterior walls of the refrigerator/freezer may
become quite warm as the compressor works to transfer
heat from the inside. Temperatures as much as 30°F
warmer than room temperatures can be expected.
NOTE
Section 2 Installation Information
2-4
Never unplug the freezer by pulling on the power
cord. Always grip the plug firmly and pull straight out
from the receptacle.
Turning the control to “OFF” turns off the compressor
but does not disconnect power to other electrical
components.
Avoid fire hazard or electric shock. Do not use an
extension cord or an adapter plug. Do not remove
any prong from the power cord.
Electrical Information
These guidelines must be followed to ensure that safety
mechanisms in the design of this freezer will operate
properly.
Refer to the serial plate for correct electrical rating. The
power cord of the freezer is equipped with at threeprong grounding plug for protection against shock hazards. It must be plugged directly in to its own properly
grounded three-prong receptacle, protected with a 15
amp time delay fuse or circuit breaker. The receptacle
must be installed in accordance with the local codes and
ordinances. Consult a qualified electrician. Receptacles
with Ground Fault Circuit Interrupters (GFCI) are NOT
RECOMMENDED. DO NOT USE AN EXTENSION CORD
OR AN ADAPTER PLUG.
If the voltage varies by 10 percent or more, freezer performance may be affected. Operating the freezer with
insufficient power can damage the motor. Such damage
is not covered under the warranty. If you suspect your
voltage is high or low, consult your power company for
testing.
To prevent the freezer from being turned off accidentally,
do not plug the unit in to an outlet controlled by a wall
switch or pull cord.
Do not pinch, knot, or bend the power cord in any
manner.
