PREVENTATIVE MAINTENANCE CLEANING PROCEDURE QF400
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 To start a cleaning cycle, 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 3 Wait about one minute or until the dump valve
light de-energizes. Lift the front cover on the water
reservoir and add the proper amount of Manitowoc Ice
Machine Cleaner.
Step 4 The ice machine will automatically time out four
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.
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 cleaning cycle is complete, the flush light will
de-energize and ice making will start automatically
