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 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.
All electrical connections and repairs to the refrigerator must com-
!
ply with all applicable codes. Refer to the certifi cation and code
requirements section of the Installation Manual.
Turn off DC power sources before attempting to remove, service,
!
or repair any of the refrigerator's electrical or electronic compo-
nents. Do not work on live electrical circuits.
Do not modify, bypass, or eliminate any of the refrigerator's electri-
!
cal components or electronic circuits.
Do not wet or spray liquids on or near electrical outlets, connec-
!
tions or components. Most liquids, including leak detection solu-
tions, are electrically conductive and pose the potential for an elec-
tric 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.
Do not use extension cords. Do not remove the grounding prong
! !
from the refrigerator AC power cord. Do not use a two prong adapt-
er 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, re-
!
move all doors and fasten all shelves with retainers.
Make sure all hardware such as hinges and fasteners (retaining
!
screws, etc.) are properly fastened.
