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. 

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

hands.

• 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.

• Do not make any alterations to the appliance. Alterations could result in electric 

shock, 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.
