Interior Cleaning and Sanitizing

GENERAL
Clean and sanitize the ice machine every six months
for efficient operation. If the ice machine requires
more frequent cleaning and sanitizing, consult a
qualified service company to test the water quality
and recommend appropriate water treatment or
installation of the AuCS
Cleaning System). If required, an extremely dirty ice
machine may be taken apart for cleaning and
sanitizing.
Use only Manitowoc approved Ice Machine
Cleaner (part number 94-0546-3) and Sanitizer
(part number 94-0565-3). It is a violation of Federal
law to use these solutions in a manner inconsistent
with their labeling. Read and understand all labels
printed on bottles before use.
Do not mix Ice Machine Cleaner and Sanitizer
solutions together. It is a violation of Federal law to
use these solutions in a manner inconsistent with
their labeling.
Wear rubber gloves and safety goggles (and/or face
shield) when handling Ice Machine Cleaner or
Sanitizer.
CLEANING PROCEDURE
Ice machine cleaner is used to remove lime scale or
other mineral deposits. It is not used to remove algae
or slime. Refer to "Sanitizing Procedure" on the next
page for removal of algae and slime. To initiate a
cleaning cycle using Manitowoc's Patented Cleaning
Technology use the following procedure.
Step 1 Set the toggle switch to the OFF position
after ice falls from the evaporator at the end of a
Harvest cycle. Or, set the switch to the OFF position
and allow the ice to melt off the evaporator.

WARNING
Never use anything to force ice from the
evaporator. Damage may result.
Step 2 To start a cleaning cycle, move the toggle
switch to the CLEAN position. The water will flow
through the water dump valve and down the drain.
The Clean light will turn on to indicate the ice
machine is in the Clean mode.
Step 3 Wait about one minute or until water starts to
flow over the evaporator.
Step 4 Add the proper amount of Manitowoc Ice
Machine Cleaner to the water trough.

Step 5 The ice machine will automatically time out a
ten-minute cleaning cycle, followed by six rinse
cycles, and then stop. The Clean light will turn off to
indicate the clean mode is completed. This entire
cycle lasts approximately 25 minutes.
NOTE: Periodic cleaning must be performed on
adjacent surface areas not contacted by the water
distribution system.
Step 6 When the cleaning process stops, move the
toggle switch to the OFF position. Refer to
"Sanitizing Procedure" on the next page.
Step 7
A. The ice machine may be set to start and finish
a cleaning procedure, and then automatically
start ice making again.
B. Wait about one minute into the cleaning cycle
(until water starts to flow over the
evaporator), then move the switch from
CLEAN to ICE position.
C. When the cleaning cycle is completed, the
clean light will turn off and a ice making
sequence will start automatically.
NOTE: After the toggle switch is moved to the ICE
position, opening the curtain switch will interrupt the
cleaning sequence. The sequence will resume from
the point of interruption when the curtain switch
closes.
