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 the section on Sanitizing for removal of
algae and slime.
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.
Never use anything to force ice from the evaporator.
Damage may result.
Step 2 To start cleaning, place the toggle switch in 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 Cleaning 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.

and stop. The Clean light will turn off to indicate the
Cleaning mode is completed. This entire cycle lasts
approximately 25 minutes.
Step 6 When the cleaning process stops, move the
toggle switch to 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 then automatically start ice
making again.
B. You must 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, an ice
making sequence will start automatically.
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
