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 | Mixed with |
|
|
|
Cleaner | 4L. (1 gal) | 500 ml (16 oz) cleaner |
|
|
|
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 | Mixed With |
|
|
|
Sanitizer | 23L. (6 gal) | 120ml (4 oz) 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.
Step 14 Reapply power and water to the ice machine and place the toggle switch in the WASH position.
Step 15 Add the proper amount of Manitowoc Ice Machine Sanitizer to the water trough.
Model | Amount of Sanitizer |
QM30 | 45 ml (1.5 oz) |
Step16 Wait until the sanitize cycle is complete (approximately 45 minutes) then place the toggle switch in the OFF position, disconnect power and water supplies to the ice machine.
