Step 7   

Remove the top cover from the ice chute and 

pour the cleaner/water solution into the evaporator. Add 
the entire amount of premixed solution (excess solution 
will exit through the overflow tube in the water reservoir).

Step 8   

Replace the ice chute cover and allow the ice 

machine to stand for 30 minutes.

Step 9   

Turn on the water supply to the ice machine.

Step 10   

Move the toggle switch to the ICE position. 

After the 15 minute delay period expires the compressor 
will energize and produce ice with the cleaning solution.

Step 11   

The ice machine will freeze and discharge the 

cleaning solution into the bin. Allow the cycle to run for 
15 minutes.

Step 12   

Place the toggle switch in the OFF position 

and refer to sanitizing procedure.

NOTE: Discard all ice produced during the cleaning 
process. Cleaning and sanitizing must be performed on 
adjacent surface areas not contacted by the water 
distribution system. Refer to Component Disassembly 
for Cleaning/Sanitizing (Page 15) - Disassemble, clean 
and sanitize the ice machine a minimum of once every 
six months.

SANITIZING PROCEDURE

Ice machine sanitizer is used to remove algae or slime. It 
is not used to remove lime scale or other mineral 
deposits. Refer to the “Cleaning Procedure” for removal 
of lime scale or other mineral deposits. 

NOTE: Sanitizing must be performed on adjacent 
surface areas not contacted by the water distribution 
system. Always perform Component Disassembly for 
Cleaning/Sanitizing procedure and a Cleaning 
Procedure before sanitizing the ice machine.

Step 1   

Turn off the water supply to the ice machine.

Step 2   

Place ICE/OFF/CLEAN toggle switch in the 

CLEAN position. The dump valve will open and drain the 
water from the evaporator and reservoir.

Step 3   

Wait approximately 30 seconds (or until the 

evaporator is drained) and place the toggle switch in the 
OFF position.

Step 4   

Refer to the chart and add the correct amount of 

sanitizer and cool water for your model ice machine.

Step 5   

Remove the top cover from the ice chute and 

pour the sanitizer/water solution into the evaporator. Add 
the entire amount of premixed solution (excess solution 
will exit through the overflow tube in the water reservoir).

Step 6   

Replace the ice chute cover and allow the ice 

machine to stand for 30 minutes.

Step 7   

Turn on the water supply to the ice machine.

Step 8   

Move the toggle switch to the ICE position. After 

the 15 minute delay period expires the compressor will 
energize and produce ice with the sanitizing solution.

Step 9   

The ice machine will freeze and discharge the 

sanitizing solution into the bin. Allow the cycle to run for 
15 minutes.

NOTE: Discard all ice produced during the sanitizing 
process.

Step 10   

Place the toggle switch in the CLEAN position. 

The ice machine will run a wash cycle, a series of rinse 
cycles and then stop. This entire cycle lasts 
approximately 30 minutes.

Step 11   

Refer to Component Disassembly for 

Cleaning/Sanitizing, (Page 15) remove clean and 
sanitize all parts listed.
