Step 7 Mix a solution of cleaner/descaler and warm
water. Depending upon 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 1/2 of the descaler/water mixture to
descale all components. The descaler 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.
Soak parts for 5 minutes (15 - 20 minutes for heavily
scaled parts). Rinse all components with clean water.
Step 9 While components are soaking, use 1/2 of the
descaler/water solution to clean all foodzone surfaces of
the ice machine and bin (or dispenser). Use a nylon
brush or cloth to thoroughly descale the following ice
machine areas:
• Side walls
• Base (area above water trough)
• Evaporator plastic parts - including top, bottom, and
sides
• Bin or dispenser
Rinse all areas thoroughly with clean water.
SANITIZING PROCEDURE
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 spray bottle 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
(or dispenser). Use a spray bottle to liberally apply the
solution. When sanitizing, pay particular attention to the
following areas:
• Side walls
• Base (area above water trough)
• Evaporator plastic parts - including top, bottom and
sides
• Bin or dispenser
Do not rinse the sanitized areas.
Step 13 Replace all removed components.
Step 14 Wait 30 minutes.
Step 15 Reapply power to the ice machine and place
the toggle switch in the CLEAN position.
Step 16 Wait until the water trough refills and water
flows over the evaporator (approximately 3 minutes).
Add the proper amount of Manitowoc Ice Machine
Sanitizer to the water trough by pouring between the
water curtain and evaporator.
Step 17 Move the toggle switch to the ICE position
and replace the front panel. The ice machine will
automatically start ice making after the sanitize cycle
is complete (approximately 35 minutes,
S3300C/ST3000C 80 minutes).
