Important Safety Instructions

Grounding Instructions

The refrigerator must be plugged into its own dedicated 115 Volt,
60 Hz., 15 Amp, AC only electrical outlet. The power cord of the
appliance is equipped with a three-prong grounding plug for your
protection against electrical shock hazards. It must be plugged
directly into a properly grounded three prong receptacle. The
receptacle must be installed in accordance with local codes and
ordinances. Consult a qualified electrician. Avoid connecting
refrigerator to a Ground Fault Interrupter (GFI) circuit. Do not use
an extension cord or adapter plug.
If the power cord is damaged, it should be replaced by an autho-
rized service technician to prevent any risk.
• Never unplug the refrigerator by pulling on the power cord.
Always grip the plug firmly, and pull straight out from the
receptacle to prevent damaging the power cord.
• Unplug the refrigerator before cleaning and before replacing
a light bulb to avoid electrical shock.
• Performance may be affected if the voltage varies by 10% or
more. Operating the refrigerator with insufficient power can
damage the compressor. Such damage is not covered under
your warranty.
• Do not plug the unit into an electrical outlet controlled by a
wall switch or pull cord to prevent the refrigerator from being
turned off accidentally.

WARNING
The circuit boards and all the wire connectors to be connected
on the boards are ESD sensitive. Take the following precautions
when servicing or handling the circuit boards and wire connec-
tors.

Precautions

• Use appropriate personal grounding equipment such as wrist
straps.
• Connect the wrist straps properly with the grounding source.
• The parts to be replaced must remain fully enclosed within
ESD packs until assembled.
• Allow only trained or escorted people in the servicing area.
• Visually check all the grounding cords.
• Use shielded packaging for shipping or storing ESD sensitive
items outside the servicing area.
• Handle unpacked ESD sensitive items only when grounded.
• Do not drag test equipment as it might develop ESD.
To move ESD sensitive parts or assemblies inside a servicing
area, use one of the following:
• Static dissipative containers
• Static shielding containers
• Conductive containers or board carriers.
