SAFETY
It is not possible to anticipate all of the conceivable ways or
conditions under which the refrigerator may be serviced or to
provide cautions as to all of the possible hazards that may result.
Standard and accepted safety precautions and equipment should
be used when working on electrical circuits and handling toxic or
fl
ammable materials. Safety goggles and other required protection
should be used during any process that can cause material
removal, such as when removing a leaking cooling unit and
cleaning components.
Read this manual carefully and understand the contents before
working on the refrigerator. Be aware of possible safety hazards
when you see the safety alert symbol on the refrigerator and in this
manual. A signal word follows the safety alert symbol and identi
fi
es
the danger of the hazard. Carefully read the descriptions of these
signal words to fully know their meanings. They are for your safety.
This signal word means a hazard, which
if ignored, can cause small personal
injury or much property damage.
This signal word means a hazard, which
if ignored, can cause dangerous personal
injury, death.
The storage of
fl
ammable materials
behind or around the refrigerator creates
a
fi
re hazard. Do not use the area
behind the refrigerator to store anything,
especially
fl
ammable materials (gasoline,
cleaning supplies, etc.).
A circuit overload can result in an
electrical
fi
re if the wires and/or fuses
are not the correct size. Use only the
wire and fuse sizes as written in the

to, or maintenance of this refrigerator can
