MANITOWOC'S CLEANING TECHNOLOGY
Manitowoc Flake Ice Machines include technology that allows the initiation and completion of a cleaning or sanitizing
cycle at the flip of a switch. This cycle will permit cleaning of all surfaces that come in contact with the water
distribution system. Periodic maintenance must be performed that includes sanitizing the bin and adjacent surface
areas, which are not contacted by the water distribution system.
Depending on local water conditions Manitowoc recommends initiating preventative maintenance cleaning
procedures between the 6 month cleanings.
This preventive maintenance removes mineral build-up from the evaporator, which results in peak efficiency and
lower operating costs.
This technology will also allow initiation and completion of a clean or sanitize cycle, after which the ice machine
automatically starts ice making again.
Refer to the cleaning/sanitizing procedure for complete details.
PREVENTATIVE MAINTENANCE CLEANING PROCEDURE
Use Ice machine cleaner part number 000000084 only.
This cleaner is used to remove lime scale or other
mineral deposits. It is not used to remove algae or slime.
Refer to "Cleaning/Sanitizing Procedure" for removal of
algae and slime. To initiate a cleaning cycle using
Manitowoc's Cleaning Technology use the following
procedure.
Step 1 Set the toggle switch to the OFF position. Open
the bin door and remove the 2 thumbscrews and white
plastic panel.
Step 2 Disconnect the water inlet line by depressing
the stainless steel tab (refer to disassembly for cleaning
for procedure).
Step 3 Move the toggle switch to the CLEAN position.
Water will flow through the water dump valve and down
the drain. The flush, gear motor, speed, dump valve and
water solenoid lights will energize to indicate the ice
machine is in the clean mode.
Step 4 Wait about one minute or until the dump valve
de-energizes. Lift the front cover on the water reservoir
and add the proper amount of Manitowoc Ice Machine
Cleaner.

Amount of Cleaner

3 ounces (90 ml)
Step 5 Reconnect the water inlet line by pushing onto
fitting and snapping into locked position.
Step 6 The ice machine will automatically time out
flush and rinse cycles, and then stop. The flush light
remains energized until the toggle switch is moved to the
OFF position. This entire cycle lasts approximately 11
minutes.
Step 7 Replace the white plastic panel and move the
toggle switch to the ice position.
NOTE: Periodic cleaning must be performed on adjacent
surface areas not contacted by the water distribution
system.
Manitowoc recommends disassembling, cleaning and
sanitizing the ice machine and bin/dispenser every six
months.
NOTE: The ice machine may be set to start and finish a
cleaning procedure, and then automatically start ice
making again. Wait about one minute into the cleaning
cycle (until the dump valve light de-energizes), then
move the switch from CLEAN to ICE position. When the
clean cycle is complete ice making starts automatically.
