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international,
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 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.

A. Nameplate Rating
1. KML-700MWH-M (water-cooled marine)
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.

maintenance and/or service should they be required.
D. Setup
1) Follow the dispenser unit/storage bin setup procedure.
2) Position the dispenser unit/storage bin in the selected permanent location.
3) Place the icemaker on top of the dispenser unit/storage bin.
4) Secure the icemaker to the dispenser unit/storage bin using the 2 mounting brackets
and the bolts provided. See Fig. 2.
5) Level the icemaker and dispenser unit/storage bin in
both the left-to-right and front-to-rear directions. If using
a storage bin, adjust the storage bin legs to make the
icemaker level.
6) Make sure the icemaker and dispenser unit/storage bin
are properly secured.
7) Seal as required by sanitation code.
8) Replace the panels in their correct positions.

E. Electrical Connection
WARNING
1. Electrical connection must be hard-wired and must meet international,
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.
2. 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.
3. THIS UNIT MUST BE GROUNDED. Failure to properly ground this unit
could result in death or serious injury.
4. Electrical connection must be made in accordance with the instructions on
