Step 5  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 1 gal. (4 l)
16 oz (500 ml) 
cleaner
,
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 Water 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.
Model Amount of Sanitizer
U0140 1 ounce (30 ml)
U0190 2 ounces (60 ml)
U0240 2 ounces (60 ml)
U0310 2 ounces (60 ml)
Wait until the sanitize cycle is complete (approximately 22 
minutes) then press the Ice button to start ice making.
