Maintenance
General
Clean and sanitize the ice machine every six months
for efficient operation. If the ice machine requires more
frequent cleaning and sanitizing, consult a water care
professional to test the water quality and recommend
appropriate water treatment. An extremely dirty ice
machine must be taken apart for cleaning and
sanitizing.
Manitowoc Ice Machine Cleaner and Sanitizer are the
only products approved for use in Manitowoc ice
machines.
This Manitowoc Ice Machine has two separate
cleaning procedures.
Cleaning/Sanitizing Procedure
This procedure must be performed a minimum of once
every six months.
• The ice machine and bin must be disassembled
cleaned and sanitized
• All ice produced during the cleaning and sanitizing
procedures must be discarded
• Removes mineral deposits from areas or surfaces
that are in direct contact with water
Heavily Scaled Cleaning Procedure
Perform this procedure if you have some or all of these
symptoms.
• Ice machine stops on Safety Shutdown
• Your water has a high concentration of minerals
• The ice machine has not been on a regular
maintenance schedule.
