SANITIZING PROCEDURE
Use sanitizer to remove algae or slime. Do not use it to
remove lime scale or other mineral deposits.
Step 1
Set the toggle switch to the OFF position after
ice falls from the evaporator at the end of a Harvest
cycle. Or, set the switch to the OFF position and allow
the ice to melt off the evaporator.
Step 2
Remove the water curtain, water distribution
tube, and the components you want to clean or sanitize.
Disassemble the water distribution tube. See the
following pages for removal/disassembly procedures for
these parts.
Step 3
Mix a solution of water and sanitizer.
Step 4
Use the sanitizing solution and a sponge or
cloth to sanitize (wipe) all parts and interior surfaces of
the ice machine. Sanitize the following areas:
A. Side walls
B. Base (area above water trough)
C. Evaporator plastic parts
D. Water Distribution tube exterior and interior
surfaces. Remove water distribution tube O-
rings then sanitize o-rings and distribution tube
E. Water pump discharge tubing
F. Exterior plastic of water pump
G. Ice thickness probe and water level probe
H. Bin or dispenser
Step 5
Rinse all sanitized areas with clear water.
Step 6
Install the removed parts, restore power and
place toggle switch in the clean position. The water will
flow through the water dump valve and down the drain.
The Clean light will turn on to indicate the ice machine is
in the Cleaning mode.
Step 7
Wait about two minutes or until water starts to
flow over the evaporator.
Step 8
Add the proper amount of Manitowoc Ice
Machine sanitizer to the water trough.
Step 9
The ice machine will automatically time out a
ten minute sanitizing cycle, followed by six rinse cycles,
and stop. The Clean light will turn off to indicate the
Cleaning cycle is completed. This entire cycle lasts
approximately 30 minutes.
Step 10
Move toggle switch from CLEAN to OFF, then
back to CLEAN. Repeat steps 7, 8 and 9.
Step 11
When the sanitizing process stops, move the
toggle switch to ICE position.

Never use anything to force ice from the evaporator.
