CLEANING PROCEDURE
Ice machine cleaner is used to remove lime scale or other mineral deposits. It is not used to remove algae or slime. Refer to “Sanitizing Procedure” on the next page for removal of algae and slime. To initiate a cleaning cycle using Manitowoc’s Patented Cleaning Technology use the following procedure.
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.
CAUTION
Never use anything to force ice from the evaporator. Damage may result.
Step 2 To start a cleaning cycle, move the toggle switch to 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 Clean mode.
Step 3 Wait about one minute or until water starts to flow over the evaporator.

B.Wait about one minute into the cleaning cycle (until water starts to flow over the evaporator), then move the switch from CLEAN to ICE position.
C.When the cleaning cycle is completed, the clean light will turn off and a ice making sequence will start automatically.
NOTE: After the toggle switch is moved to the ICE position, opening the curtain switch will interrupt the cleaning sequence. The sequence will resume from the point of interruption when the curtain switch closes.
