Caution

Do not immerse electrical connectors or motors for any 

components in water, cleaner, or sanitizer solutions.

Use half of the cleaner and 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 6  While components are soaking, use half of the 

cleaner and 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 7  Mix a solution of sanitizer and warm water.

Solution Type

Mixed With

Sanitizer

3 gal. (12 l)

2 oz (60 ml) sanitizer

Use half of the sanitizer and 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 and water solution. Do not 

rinse parts after sanitizing.

Step 8  Use half of the sanitizer and water solution to 

sanitize all foodzone surfaces of the ice machine and bin. 

Use a spray bottle 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 9  Apply food grade lubricant to all o-rings, then 

replace all removed components. Wait 10 minutes and then 

reapply power and water to the ice machine
Step 10  Press the Clean button. Water will flow through 

the water dump valve and down the drain. Wait until the 

water trough refills, then add the proper amount of ice 

machine sanitizer to the water trough.
