WARNING
This icemaker should be destined only to the use for which it has been

damage resulting from improper, incorrect, and unreasonable use.
To reduce the risk of death, electric shock, serious injury, or re, follow
basic precautions including the following:
• This unit requires an independent power supply. See the nameplate for proper
voltage and breaker/fuse size. Failure to use a proper breaker or fuse can
result in a tripped breaker, blown fuse, or damage to existing wiring. This
could lead to heat generation or re.
• THIS APPLIANCE MUST BE GROUNDED: This unit is equipped with a
3-prong grounding plug to reduce the risk of potential shock hazards. It must
be plugged into a properly grounded, independent wall outlet. If the outlet is a
2-prong outlet, it is your personal responsibility to have a qualied electrician
replace it with a properly grounded, independent 3-prong wall outlet. Do not
remove the ground prong from the power cord and do not use an adapter
plug.
• Do not use an extension cord.
• Make sure the control switch is in the "OFF" position before plugging in or
unplugging the unit to reduce the risk of electric shock.
• Do not use a unit with a damaged power cord. The power cord should not be
altered, jerked, bundled, weighed down, pinched, or tangled. Such actions
could result in electric shock or re. To unplug the unit, be sure to pull the
plug, not the cord, and do not jerk the cord.
• To reduce the risk of electric shock, do not touch the plug, control switch, or
service switch with damp hands.
• This unit should be disassembled or repaired only by qualied service
personnel to reduce the risk of electric shock, injury, or re.
