Cleaning / Sanitizing Procedure
CLEANING PROCEDURE
Ice machine cleaner is used to remove lime scale and
mineral deposits. Ice machine sanitizer disinfects and
removes algae and slime.
Step 1 Remove front door and top cover. This will
allow easiest access for adding cleaning and
sanitizing solutions.
Step 2 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
Use only Manitowoc approved Ice Machine
Cleaner and Sanitizer for this application
(Manitowoc Cleaner part number 9405463 and
Manitowoc Sanitizer part number 9405653). It is a
violation of Federal law to use these solutions in a
manner inconsistent with their labeling. Read and
understand all labels printed on bottles before
use.
!
Caution
Do not mix Cleaner and Sanitizer solutions
together. It is a violation of Federal law to use
these solutions in a manner inconsistent with their
labeling.
!
Warning
Wear rubber gloves and safety goggles (and/or
face shield) when handling ice machine Cleaner
or Sanitizer.
!
Caution
Never use anything to force ice from the
evaporator. Damage may result.
