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.

• 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: 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 use an extension cord.

• To reduce the risk of electric shock, do not touch the control switch, service switch,
or plug with damp hands. Make sure the control switch is in the "OFF" position
before plugging in or unplugging the appliance.

• 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.

WARNING, continued

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

• 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 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 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 the normal
operating ambient temperature is above 90°F (32°C), the compressor insulation
cover must be removed.

• 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."

• 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.

II. Installation and Operating Instructions

WARNING

• The appliance must be installed in accordance with applicable national, state, and
local codes and regulations.

• 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.

• CHOKING HAZARD: Ensure all components, fasteners, and thumbscrews
are securely in place after installation. Make sure that none have fallen into the
storage bin.

A. Location

NOTICE

• The appliance is not intended for outdoor use. Normal operating ambient
temperature must be within 45°F to 100°F (7°C to 38°C). If the normal operating
ambient temperature is above 90°F (32°C), the compressor insulation cover
must be removed. Normal operating water temperature must be within 45°F to
90°F (7°C to 32°C). Operation of the appliance, for extended periods, outside of
these normal temperature ranges may affect appliance performance.

• The appliance will not work at sub-freezing temperatures. To prevent damage
to the water supply line, drain the appliance if the air temperature is going to go
below 32°F (0°C). See "IV. Preparing the Appliance for Periods of Non-Use."

• The appliance should not be located next to ovens, grills, or other high heat producing
equipment.

• On air-cooled model, allow at least 12" (30 cm) clearance on the left side and 6" (15 cm)
clearance at rear, right side, and top for proper air circulation and ease of maintenance
and/or service should they be required. On water-cooled model, allow 6"(15 cm)
clearance at rear, sides, and top.

• The location should provide a rm and level foundation for the appliance.

B. Checks Before Installation

• Visually inspect the exterior of the shipping container and immediately report any
damage to the carrier. Upon opening the container, any concealed damage should also
be immediately reported to the carrier.

• Remove the shipping carton, tape, and packing material. If any are left in the appliance,
it will not work properly.

• See the nameplate on the rear panel, and check that your voltage supplied corresponds
with the voltage specied on the nameplate.

• Remove the panels to prevent damage when installing the appliance. See "II.C. How to
Remove Panels."

• Remove the package containing the accessories.

• Remove the protective plastic lm from the panels. If the appliance is exposed to the
sun or to heat, remove the lm after the appliance cools.

• Check that the refrigerant lines do not rub or touch lines or other surfaces, and that the
fan blade (if applicable) turns freely.

• Check that the compressor is snug on all mounting pads.
