Removed Parts Cleaning Procedure

• Mix a solution of cleaner and lukewarm water Cleaner : Water Ratio 1gal. (4L) Water = 16 oz (500 ml) cleaner

• Use 1/2 of the cleaner/water mixture 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 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

• While components are soaking, use 1/2 of the cleaner/water solution to clean all food zone 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

Removed Parts Sanitizing Procedure

• Mix a solution of sanitizer and lukewarm water Sanitizer : Water Ratio 3 gal. (12 L) = 2 oz (60 ml) sanitizer

• 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

• Replace all removed components
