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 identifi es
the danger of the hazard. Carefully read the descriptions of these
signal words to fully know their meanings. They are for your safety.
CAUTION! This signal word means a hazard, which if ignored,
can cause small personal injury or much property damage.
WARNING! This signal word means a hazard, which if ignored,
can cause dangerous personal injury, death.
Norcold refrigerators are designed and equipped for the use of
propane gas only. Do not modify, alter, or equip the refrigerator to
any other fuel (natural gas, butane, etc.).
Incorrect installation, adjustment, alteration, or maintenance of the
refrigerator can cause personal injury, property damage, or both.
Do not smoke, light fi res, or create sparks when working on
propane gas system.
Propane gas is highly fl ammable and explosive. Do not use
an open fl ame for leak testing any of propane gas system
components.
Always use two wrenches to tighten or loosen propane gas
connections. Damaged connections, piping, and components
create the potential for gas leaks.
All electrical connections and repairs to the refrigerator must
comply with all applicable codes. Refer to the certifi cation and code
requirements section of the Installation Manual.
Turn off AC power and DC power sources before attempting to
remove, service, or repair any of the refrigerator’s electrical or
electronic components. Do not work on live electrical circuits.
Do not modify, bypass, or eliminate any of the refrigerator’s
electrical components, electronic circuits, or propane gas system
components.
Do not wet or spray liquids on or near electrical outlets, connections
or components. Most liquids, including leak detection solutions, are
electrically conductive and pose the potential for an electric shock
hazard, short electrical components, damage electronic circuits,
and/or ignite a fi re.
Do not use leak test solutions that contain ammonia or chlorine.
Ammonia and chlorine degrade copper and brass components.
The cooling unit is a sealed system under pressure! Do not try to
repair or recharge the cooling unit. Do not bend, drop, weld, drill,
puncture, saw, or strike the cooling unit.

Handle a leaking cooling unit with extreme caution! The cooling unit
contains ammonia, hydrogen, and sodium chromate. Ammonia can
cause severe skin and eye burns. Hydrogen is highly fl ammable,
can ignite and burns with an intense fl ame. Certain chromium
compounds, such as sodium chromate, are carcinogenic.
Do not use extension cords. Do not remove the grounding prong
from the refrigerator AC power cord. Do not use a two prong
adapter to connect the refrigerator to the AC outlet.
Do not over-fuse electrical circuits. Use specifi ed fuses and AWG
wire sizes. The specifi cation section of this manual provides fuse
size information. Refer to the Installation Manual for the correct
AWG wire size specifi cations.
Prevent child entrapment! Before disposing of the refrigerator,
remove all doors and fasten all shelves with retainers.
Make sure all hardware such as hinges and fasteners (retaining
screws, etc.) are properly fastened.
Obey the instructions in this manual with regard to intake and
exhaust venting specifi cations.
Do not install the refrigerator directly on carpet. Put the refrigerator
on a metal or wood panel that extends the full width and depth of
the refrigerator.
Some of the refrigerator’s metal components have sharp corners
and edges. Wear hand protection, such as cut resistant gloves,
and exercise extreme care when handling the refrigerator.
