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.

• This icemaker 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.

• THIS ICEMAKER MUST BE GROUNDED: This icemaker 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.

• Do not use an extension cord.

• To reduce the risk of electric shock, make sure the control switch is in the "OFF"
position before plugging in or unplugging the icemaker.

• To reduce the risk of electric shock, do not touch the control switch or plug with
damp hands.

• Do not use an icemaker 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 icemaker, be sure to pull the plug, not
the cord, and do not jerk the cord.

• Do not make any alterations to the icemaker. Alterations could result in electric
shock, injury, re, or damage to the icemaker.

• Children should be properly supervised around the 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.

• 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.

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 "IV. Preparing the Appliance for Periods
of Non-Use."

• If water collects in the bin and will not drain, turn off the icemaker and close the
water supply line shut-off valve. Call for service.

• Do not leave the icemaker on during extended periods of non-use, extended
absences, or in sub-freezing temperatures. To properly prepare the icemaker for
these occasions, follow the instructions in "V. Preparing the Icemaker for Periods of
Non-Use."
