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 Remove all ice from the ice storage bin.
Step 3 To start clean cycle, move the toggle switch
to the WASH position. The water will flow into the
water trough, then down the drain through the water
overflow tube.
Step 4 Wait about three minutes or until water starts
to flow over the evaporator.
Step 5 Add 45ml (1.5 oz.) of Manitowoc Ice
Machine Cleaner to the water trough.
Step 6 The ice machine will automatically time out a
ten-minute cleaning cycle, followed by eight rinse
cycles, and then stop. This entire cycle lasts
approximately 43 minutes.
Step 7 When the cleaning process stops, move the
toggle switch to the OFF position. Refer to
"Sanitizing Procedure".
NOTE: If the toggle switch is moved to the off
position, the clean cycle will be terminated.
