Section 4
Interior Cleaning and Sanitizing
GENERAL
Perform an In Place Cleaning/Sanitizing procedure
monthly and a Cleaning/Sanitizing procedure every
12 months for efficient operation. If the ice machine
requires more frequent cleaning and sanitizing, consult a
qualified service company to test the water quality and
recommend appropriate water treatment. An extremely
dirty ice machine must be taken apart for cleaning and
sanitizing.
! Caution
Damage to the ice machine evaporator caused by
incorrect chemical usage is not covered by the
warranty. Use Manitowoc Ice Machine Cleaner (part
number 000000084) and Sanitizer (part number
94-0565-3) only.
IN PLACE CLEANING/SANITIZING PROCEDURE
This procedure allows monthly in place cleaning of all
surfaces that come in contact with the water system. The
ice machine requires disassembly and cleaning/
sanitizing a minimum of once every 12 months. The
quality of your potable water supply may require more
frequent cleaning intervals.
Use ice machine cleaner to remove lime scale or other
mineral deposits. Ice machine sanitizer disinfects and
removes algae and slime.
NOTE: All ice must be removed from the bin.
!
Follow all labels and warnings on cleaner and
sanitizer bottles.
Step 1 Prepare 4 oz (1/2 cup) of undiluted Manitowoc
Ice Machine Cleaner (part number 000000084 only) in a
container that will fit easily under the lifted water
shutters. Refer to page 18 to identify the water shutters.
