around the refrigerator creates a fi re hazard.
ATTENTION
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 fire if the wires and/or fuses
are not the correct size. Use only the wire and fuse sizes as written in
the "Installation Manual."
■ Incorrect installation, adjustment, change to, or maintenance of this
refrigerator can cause personal injury, property damage, or both. Have
service and maintenance work done by your dealer or by an authorized
Norcold Service Center.
■ Disconnect the DC power source before doing any maintenance work on
the refrigerator.
■ Do not bypass or change the refrigerator's electrical components or
features.
■ Do not spray liquids near electrical outlets, connections, or the refrigera-
tor components. Many liquids are electrically conductive and can cause
a shock hazard, electrical shorts, and in some cases fire.
■ Do not touch the evaporator or other metal parts inside the refrigerator
cabinet with wet hands because they can freeze to the refrigerator.
■ The rear of the refrigerator has sharp edges and corners. To prevent cuts
or abrasions when working on the refrigerator, be careful and wear cut
resistant gloves.
■ When you discard an appliance, remove all doors to prevent accidental
entrapment and suffocation.
■ At regular intervals, make sure that the refrigerator vent areas and the
air pathway between the vents is completely free from any flammable
material or blockage. After a period of storage, it is especially important
to check these areas for any flammable material or blockage caused by
animals and insects.
■ Risk of fire or explosion. A flammable refrigerant (R600a) is used. To be
repaired only by trained Service personnel. Do not puncture refrigerant
tubing.
■ Red painted tubing indicates that a flammable refrigerant is present.
