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.
Solution Type Water
Cleaner 4L. (1 gall)
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.
Solution Type Water
Sanitizer 23 L. (6 gal )
Mixed with
500 ml (16 oz) cleaner
Mixed With
120 ml (4 ounces) sanitizer
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.
