Step 7 Mix a solution of 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 descale all foodzone surfaces
of the ice machine and bin (or dispenser). Use a nylon
brush or cloth to thoroughly clean 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 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
(or dispenser). Use a cloth or sponge 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 Reapply power to the ice machine and place
the toggle switch in the CLEAN position.
Step 15 Wait about two minutes or until water starts to
flow over the evaporator. Add the proper amount of
Manitowoc Ice Machine Sanitizer to the water trough by
pouring between the water curtain and evaporator.
Step 16 The ice machine will stop after the sanitize
cycle (approximately *35 minutes). Place the toggle
switch in the OFF position and disconnect power to the
ice machine.
*S3300/ST3000 Only - 80 minutes.
