PROCEDURE TO CLEAN HEAVILY SCALED FLAKE/NUGGET ICE MACHINES

Ice machines that are heavily scaled or have not been cleaned on a regular basis will need to run this Procedure.
Failure to do so may result in binding of the auger as the lime scale releases from the auger and evaporator barrel.
Step 1 Remove panels and set the ICE/OFF/CLEAN
toggle switch to the OFF position.
Step 2 Remove all ice from the bin.
Step 3 Turn off the water supply to the ice machine.
Step 4 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 5 Wait approximately 30 seconds (or until the
evaporator is drained) and place the toggle switch in the
OFF position.
Step 6 Refer to chart and add the correct amount of
cleaner for your model ice machine.

Step 7 Turn on the water supply to the ice machine.
Leave the cleaner/water solution in the evaporator

compressor will energize and produce ice with the
cleaning solution. Continue the freeze cycle for 15
minutes.

then follow the standard cleaning and sanitizing
procedures (Pages 4-5 & 4-6).
