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 installation, 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 install, operate, 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 the appliance.
• The appliance must be installed in accordance with applicable national, state, and
local codes and regulations.
• Electrical connection must meet national, state, and local electrical code
requirements. Failure to meet these code requirements could result in death,
electric shock, serious injury, re, or damage.
• 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 fuse, damage to
existing wiring, or component failure. This could lead to heat generation or re.
• THE APPLIANCE MUST BE GROUNDED: Failure to properly ground the
appliance may result in death, electric shock, or re.
• To reduce the risk of electric shock, do not touch the power switch, control switch,
or plug (on corded models) with damp hands.

5
WARNING, continued
For Corded Models
• This appliance is equipped with a NEMA5-15 three-prong grounding plug to
reduce the risk of potential shock hazards. Corded models 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 plug and do not use an adapter plug. Failure to follow these
instuctions may result in death, electric shock, or re.
• Before servicing, move the power switch to the "OFF" position. Unplug the
appliance from the electrical outlet.
• 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.
For Hard-Wired Models
• Electrical connection must be hard-wired.
• Before servicing, move the power switch to the "OFF" position. Turn off the power
supply. Lockout/Tagout to prevent the power supply from being turned back on
inadvertently.
For All Models
• Do not splash, pour, or spray water directly onto or into the appliance. This might
cause short circuit, electric shock, corrosion, or failure.
• Do not make any alterations to the appliance. Alterations could result in electric
shock, injury, re, or damage to the appliance.
• 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 the appliance.
• Do not climb, stand, or hang on the appliance or appliance door or allow children or
animals to do so. Serious injury could occur or the appliance could be damaged.
• Be careful not to pinch ngers when opening and closing the door. Be careful when
opening and closing the door when children are in the area.

6
WARNING, continued
• 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.
• Do not place anything on top of the appliance. Foreign objects or moisture could
enter the appliance and result in electric shock or re.
NOTICE
• Protect the oor when moving the appliance to prevent damage to the oor.
• Follow the water supply, drain connection, and maintenance instructions 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).
• If water collects in the bin and will not drain, turn off the appliance and close the
water supply line shut-off valve. Call for service.
• 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 "IV. Preparing the Appliance for Periods
of Non-Use."
• Keep ventilation openings, in the appliance enclosure or in the built-in structure,
clear of obstruction.
• Do not place objects on top of the appliance.
• The storage bin is for ice use only. Do not store anything else in the storage bin.

or plug (on corded models) with damp hands.
• For Corded Models
• This appliance is equipped with a NEMA5-15 three-prong grounding plug to
reduce the risk of potential shock hazards. Corded models 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 plug and do not use an adapter plug. Failure to follow these
instuctions may result in death, electric shock, or re.
• Do not use an extension cord.
• Make sure the power switch is in the "OFF" position before plugging in or
unplugging the appliance to reduce the risk of electric shock.
• Do not use an appliance with a damaged power cord. The power cord should not

H. Startup
WARNING
• All parts are factory-adjusted. Improper adjustments may adversely affect safety,
performance, component life, and warranty coverage.
• To reduce the risk of electric shock, do not touch the power switch, control switch,
or plug (on corded models) with damp hands. If you have to slide the appliance
back for a built-in installation, make sure you do not damage or pinch the water
supply line, drain line, or power cord.
NOTICE
• If the appliance is turned off, wait for at least 3 min. before restarting the appliance
to prevent damage to the compressor.
• At startup, conrm that all internal and external connections are free of leaks.
1) Open the water supply line shut-off valve.
2) Remove the top and front panels.
3) Make sure the power switch is in the "OFF" position.
4a) Corded Models: Plug the icemaker into the electrical outlet.
