step 7 Mix a solution of cleaner and warm water.
Depending on the amount of mineral buildup, a larger
quantity of solution may be required. Use the ratio in the
table below to mix enough solution to thoroughly clean
all parts.
step 8 Use ½ of the cleaner/water solution 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 brush, sponge or cloth
(not a wire brush) to carefully clean the parts. Soak the
parts for 5 minutes (15 – 20 minutes for heavily scaled
parts). Rinse all components with clean water.
step 9 While components are soaking, use ½ of the
cleaner/water solution to clean all foodzone surfaces of
the ice machine and bin. Use a nylon brush or cloth to
thoroughly clean the following ice machine areas:
• Evaporator plastic parts – including top,
bottom and sides
• Bin bottom, sides and top
Rinse all areas thoroughly with clean water.
step 10 Mix a solution of sanitizer and warm water.
step 11 Use 1/2 of the sanitizer/water solution to
sanitize all removed components. Use a cloth or sponge
to liberally apply the solution to all surfaces of the
removed parts or soak the removed parts in the
sanitizer/water solution. Do not rinse parts after
sanitizing.
step 12 Use 1/2 of the sanitizer/water solution to
sanitize all foodzone surfaces of the ice machine and
bin. Use a cloth or sponge to liberally apply the solution.
When sanitizing, pay particular attention to the following
areas:
• Evaporator plastic parts - including top,
bottom and sides
• Bin bottom, sides and top
Do not rinse the sanitized areas.
step 13 Replace all removed components.
step 14 Reapply power and water to the ice machine
and place the toggle switch in the WASH position.
step 15 Add the proper amount of Manitowoc Ice
Machine Sanitizer to the water trough.
step 16 Wait until the sanitize cycle is complete
(approximately 45 minutes) then place the toggle switch
in the OFF position, disconnect power and water
supplies to the ice machine.
