nWarning
All Manitowoc ice machines require the ice storage
system (bin, dispenser, etc.) to incorporate an ice
deflector.
Prior to using a non-Manitowoc ice storage system
with other Manitowoc ice machines, contact
the manufacturer to assure their ice deflector is
compatible with Manitowoc ice machines.
Model/Serial Number Location
These numbers are required when requesting
information from your local Manitowoc Distributor,
service representative, or Manitowoc Ice. The model
and serial number are listed on the OWNER WARRANTY
REGISTRATION CARD. They are also listed on the MODEL/
SERIAL NUMBER DECAL affixed to the front and rear of
the ice machine.

• Warranty Verification
• Warranty Registration
• View and download a copy of the warranty Owner
Warranty Registration Card
Warranty coverage begins the day the ice machine is
installed.

Part Number STH025 11/16 19
LuminIce® II
The LuminIce® growth inhibitor recirculates the air in the
ice machine foodzone over a UV bulb. This process will
inhibit the growth of common micro-organisms on all
exposed foodzone surfaces.
• LuminIce® bulbs require replacement on a yearly
basis.
• The control board can be set to automatically display
a reminder after 12 months.
• A remote light is available for reminder indication.
NOTE: LuminIce® and LuminIce® II bulbs are not
interchangeable; verify your model before ordering a
replacement bulb.
Cleanup Procedure for Accidental Bulb Breakage
The cleanup procedure is identical to the procedure used
to clean up compact fluorescent (CFL) or fluorescent tube
lights. These lights contain a small amount of mercury
sealed within a glass tube. Breaking these types of lights
will release mercury and mercury vapor. The broken bulb
can continue to release mercury vapor until it is cleaned
up and removed.
The latest EPA procedures can be viewed on their website
at www.epa.gov/cfl/cflcleanup.html.
