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 fire, follow basic precautions including the following:

•Only qualified 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 be hard-wired and must meet national, state, and local electrical code requirements. Failure to meet these code requirements could result in death, electric shock, serious injury, fire, or damage.

•The icemaker requires an independent power supply of proper capacity. See the nameplate for electrical specifications. 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 fire.

•THE ICEMAKER MUST BE GROUNDED. Failure to properly ground the icemaker could result in death or serious injury.

•Move the control switch to the "OFF" position and turn off the power supply before servicing. Lockout/Tagout to prevent the power supply from being turned back on inadvertently.

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

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

•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.

6

WARNING, continued

•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 flammable substances near the appliance. They might catch fire.

•Keep the area around the appliance clean. Dirt, dust, or insects in the appliance could cause harm to individuals or damage to the appliance.

Additional Warning for Remote Models

•THE REMOTE CONDENSER UNIT MUST BE GROUNDED. The power supply and ground connection to the remote condenser unit are supplied from the icemaker. Failure to properly ground the remote condenser unit could result in death or serious injury.

•Wire routing (conduit) and disconnect (if required) must meet national, state, and local electrical code requirements. Failure to meet these code requirements could result in death, electric shock, serious injury, fire, or damage.

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 floor drain.

•Install the icemaker 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 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 "IV. Preparing the Icemaker for Periods of

Non-Use."

•Do not place objects on top of the appliance.

•The dispenser unit/ice storage bin is for ice use only. Do not store anything else in the dispenser unit/ice storage bin.
