Step 8 While components are soaking, use 1/2 of the
descaler/water solution to descale all food zone 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 9 Mix a solution of sanitizer and lukewarm water.
Solution Type Water Mixed With
Sanitizer 3 gal. (12 L) 2 oz (60 ml) sanitizer
Step 10 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 11 Use 1/2 of the sanitizer/water solution to
sanitize all food zone 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.
