CLEANING PROCEDURE

Ice machine cleaner is used to remove lime scale and
other mineral deposits. Ice machine sanitizer disinfects
and removes algae and slime.
NOTE: All ice must be removed from the bin.
Step 1 Prepare 4 oz (1/2 cup) of undiluted Manitowoc
Ice Machine Cleaner (part number 000000084 only) in a
container that will fit easily under the lifted water
shutters. Refer to page 3-1 to identify the water shutters.
Model
SM50
Step 2 Press the Clean switch. The ice machine will
initiate a 2 minute harvest to remove any remaining ice
from the evaporator.
Step 3 Remove all ice from the bin.
Step 4 Wait 3 minutes until the Clean light flashes,
then add the prepared Manitowoc Cleaner by lifting the
water shutters and pouring directly into the spray area.
The ice machine will automatically time out a ten
minute cleaning cycle, followed by eight rinse cycles,
and stop. The Clean light will turn off to indicate the
clean cycle is complete. This entire cycle lasts
approximately 30 minutes.
Step 5 When the cleaning process stops, disconnect
power and remove all parts as described in Removal of
Parts for Cleaning and Sanitizing.
Follow all labels and warnings on cleaner and
sanitizer bottles.

Step 7 Take all removed components to a sink for
cleaning. Use 1/2 of the cleaner/water mixture to clean
all components. The cleaner solution will foam when it
contacts lime scale and mineral deposits; once the
foaming stops, use a soft-bristle nylon brush, sponge or
cloth (NOT a wire brush) to carefully clean the parts.
Disassemble the spray bar, remove nozzles and inserts
and soak for 5 minutes. For heavily scaled parts, soak in
solution for 15 – 20 minutes. Rinse all components with
clean water.
Step 8 While components are soaking, use the other
1/2 of the cleaner/water solution and a nylon brush or
cloth to clean inside of ice bin. Clean inside of door,
door gasket, bin, top of evaporator and evaporator
bucket. Rinse all areas thoroughly with clean water.
