result in death, serious injury, or damage to the unit.
WARNING Indicates a hazardous situation which could result in death or
serious injury.
CAUTION Indicates a situation which could result in damage to the unit.
IMPORTANT Indicates important information about the use and care of the
unit.
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:
•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, re, or severe damage to
equipment.
•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 fuses, 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.
•Donotmakeanyalterationstotheunit.Alterationscouldresultinelectric
shock, injury, re, or damage to the unit.

I. Specications
A. Nameplate Rating
1. KM-600MAH (air-cooled)
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.
We reserve the right to make changes in specications and design without prior notice.

C. Location
CAUTION
1. This icemaker is not intended for outdoor use. Normal operating ambient
temperature should be within 45°F to 100°F (7°C to 38°C); Normal operating
water temperature should be within 45°F to 90°F (7°C to 32°C). Operation
of the icemaker, for extended periods, outside of these normal temperature
ranges may affect icemaker performance.
2. This icemaker will not work at sub-freezing temperatures. To prevent damage
to the water supply line, drain the icemaker if the air temperature is going to
gobelow32°F(0°C).See"III.C.PreparingtheIcemakerforLongStorage."
For best operating results:
•Theicemakershouldnotbelocatednexttoovens,grills,orotherhighheatproducing
equipment.
•Thelocationshouldprovidearmandlevelfoundationfortheequipment.
