WARNING

This icemaker 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 eventual damage caused by improper, incorrect, and unreasonable use.

To reduce the risk of death, electric shock, serious injury, or re, follow basic precautions including the following:

• This unit requires an independent power supply. See the nameplate for proper voltage and breaker/fuse size. Failure to use a proper breaker or fuse can result in a tripped breaker, blown fuse, or damage to existing wiring. This could lead to heat generation or re.

• THIS UNIT MUST BE GROUNDED. Failure to properly ground this unit could result in death or serious injury.

• This unit should be disassembled or repaired only by qualied service personnel to reduce the risk of electric shock, injury, or re.

See the nameplate for electrical and refrigeration specications. This nameplate is located on the rear panel. Since this nameplate is located on the rear panel of the icemaker, it cannot be read when the back of the icemaker is against a wall or against another piece of kitchen equipment. Therefore, the necessary electrical and refrigeration information is also on the rating label, which can be easily seen by removing only the front panel of the icemaker.
