Important Safety Information
Throughout this manual, notices appear to bring your attention to situations which could
result in death, serious injury, damage to the appliance, or damage to property.
WARNING Indicates a hazardous situation which could result in death or
serious injury.
NOTICE Indicates a situation which could result in damage to the
appliance or property.
IMPORTANT Indicates important information about the use and care of the
appliance.
WARNING
The appliance should be destined only to the use for which it has been expressly
conceived. Any other use should be considered improper and therefore dangerous.
The manufacturer cannot be held responsible for injury or damage resulting from
improper, incorrect, and unreasonable use. Failure to service and maintain the
appliance in accordance with this manual will adversely affect safety, performance,
component life, and warranty coverage and may result in costly water damage.
To reduce the risk of death, electric shock, serious injury, or re, follow basic
precautions including the following:
• Only qualied service technicians should install and service this appliance.
• The appliance must be installed in accordance with applicable national, state, and
local codes and regulations. Failure to meet these code requirements could result in
death, electric shock, serious injury, re, or damage to the appliance.
• To reduce the risk of electric shock, do not touch the appliance power switch or plug
with damp hands.
• Make sure the appliance power switch is in the "OFF" position before plugging in or
unplugging the appliance.
• Before servicing, move the power switch to the "OFF" position. Unplug the
appliance from the electrical outlet.
• The appliance requires an independent power supply of proper capacity. See the
nameplate for electrical specications. Failure to use an independent power supply
of proper capacity can result in a tripped breaker, blown fuses, damage to existing
wiring, or component failure. This could lead to heat generation or re.
•THE APPLIANCE MUST BE GROUNDED. The appliance is equipped with a
NEMA5-15 three-prong grounding plug to reduce the risk of potential shock
hazards. It must be plugged into a properly grounded, independent 3-prong wall
outlet. If the outlet is a 2-prong outlet, it is your personal responsibility to have
a qualied 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. Failure to properly ground the appliance could result in death or
serious injury.
• Do not make any alterations to the appliance. Alterations could result in electric
shock, injury, re, or damage to the appliance.

6
WARNING, continued
• Do not use an extension cord.
• Do not use an appliance 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 appliance, be sure to pull the plug, not
the cord, and do not jerk the cord.
• The GREEN ground wire in the factory-installed power cord is connected to the
appliance. If it becomes necessary to remove or replace the power cord, be sure to
connect the power cord's ground wire.
• Do not place ngers or any other objects into the ice discharge opening.
• The appliance is not intended for use by persons (including children) with reduced
physical, sensory, or mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction concerning use of the
appliance by a person responsible for their safety.
• Children should be properly supervised around this appliance.
• Do not climb, stand, or hang on the appliance or allow children or animals to do so.
Serious injury could occur or the appliance could be damaged.
• Do not use combustible spray or place volatile or ammable substances near the
appliance. They might catch re.
• Keep the area around the appliance clean. Dirt, dust, or insects in the appliance
could cause harm to individuals or damage to the appliance.
NOTICE
• Follow the instructions in this manual carefully to reduce the risk of costly water
damage.
• In areas where water damage is a concern, install in a contained area with a oor
drain.
• Install the appliance in a location that stays above freezing. Normal operating
ambient temperature must be within 45°F to 100°F (7°C to 38°C).
• Do not leave the appliance on during extended periods of non-use, extended
absences, or in sub-freezing temperatures. To properly prepare the appliance
for these occasions, follow the instructions in "VI.C. Preparing the Appliance for
Periods of Non-Use."
• Do not place objects on top of the appliance.
• The ice storage bin is for ice use only. Do not store anything else in the ice storage
bin.
