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.
Step 8
Move the toggle switch to the ICE position. The
compressor will energize and produce ice with the
cleaning solution. Continue the freeze cycle for 15
minutes.
Step 9
Move the toggle switch to the OFF position,
then follow the standard cleaning (Page 13) and
sanitizing procedures (Page 14).
CLEANING PROCEDURE
Ice machines that are heavily scaled or have not been
cleaned on a regular basis will need to run the Heavily
Scaled Cleaning Procedure before this one. Failure to
do so may result in binding of the auger as the lime scale
releases from the auger and evaporator barrel.
Ice machine cleaner is used to remove lime scale or
other mineral deposits. It is not used to remove algae or
slime. Refer to the “Sanitizing Procedure” for removal of
algae and slime.
Step 1
Remove panels and set the ICE/OFF/CLEAN
toggle switch to the OFF position.
Step 2
Turn off the water supply to the ice machine.
Step 3
Remove all ice from the bin.
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 premix the correct solution of
cleaner and cool water for your ice machine.
