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/Descaling 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 chart and premix the correct solution
of sanitizer and cool water for your model ice machine.
