PREVENTATIVE MAINTENANCE DESCALING PROCEDURE

Ice machine descaler is used to remove lime scale or other mineral deposits. It is not used to remove algae or slime. Refer to
"Sanitizing Procedure" for removal of algae and slime. To initiate a descaling cycle using Manitowoc's Cleaning Technology use
the following procedure.
Step 1 To start a descaling cycle, move the toggle switch
to the CLEAN position. Water will flow through the water
dump valve and down the drain.
Step 2 Remove the top panel and translucent plastic ice
chute cover. Wait about one minute then add the proper
amount of Manitowoc Ice Machine Descaler. Rinse the
descaler from the top of the evaporator with 2 ounces (60
ml) of clear water and re-install cover.

Step 3 The ice machine will run a wash cycle, a series
of rinse cycles and then stop. This entire cycle lasts
approximately 30 minutes.
NOTE: Periodic descaling must be performed on adjacent
surface areas not contacted by the water distribution system.
NOTE: The ice machine may be set to start and finish a
descaling procedure, and then automatically start ice making
again.
A. After descaler is added, move the switch from
CLEAN to ICE position.
B. When the descaling cycle is complete, ice making
will start automatically.
Changing toggle switch position during descaling cycle:
1. Less than 60 seconds into Clean cycle - The Clean cycle
will end when the toggle switch is moved to the OFF
position.
2. More than 60 seconds into Clean cycle - The ice machine
will complete the Clean cycle. Toggle switch position
will determine the next cycle after the Clean cycle is
completed.
• CLEAN POSITION - The ice machine will wait for a change
in toggle switch position.
• OFF POSITION - The ice machine will wait for a change in
toggle switch position.
• ICE POSITION - The ice machine will start making ice
automatically.
Manitowoc recommends disassembling, descaling and
sanitizing the ice machine and dispenser every six months.
