Descaling and Sanitizing

GENERAL

You are responsible for maintaining the ice machine
in accordance with the instructions in this manual.
Maintenance procedures are not covered by the warranty.
Descal and sanitize the ice machine every six months for
efficient operation. If the ice machine requires more frequent
descaling and sanitizing, consult a qualified service company
to test the water quality and recommend appropriate water
treatment. If required, an extremely dirty ice machine may
be taken apart for descaling and sanitizing.
Sanitizing for Exterior, Remedial, and Detailed procedures
can be performed independently and more frequently than
descaling when needed.
Using non-Manitowoc descalers, sanitizers, descalers or
solutions may result in bodily harm and/or cause damage to
the ice machine that is not covered under the warranty.
Use only Manitowoc approved Ice Machine Descaler
(part number 000000084) and Sanitizer (part number
94-0565-3). Do not mix Descaler and Sanitizer solutions
together. 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.
Wear rubber gloves and safety goggles (and/or face
shield) when handling Ice Machine Descaler or Sanitizer.

PROCEDURES

This Manitowoc ice machine has three separate cleaning
procedures.
Preventative Maintenance Descaling Procedure
Perform this procedure as required for your water
conditions. Recommended monthly.
• Allows descaling the ice machine without removing all of
the ice from the bin
• Removes mineral deposits from areas or surfaces that
are in direct contact with water during the freeze cycle
(reservoir, evaporator, auger, drain lines)
Descaling/Sanitizing Procedure
This procedure must be performed a minimum of once every
six months.
• All ice must be removed from the bin
• The ice machine and bin must be disassembled descaled
and sanitized
• The ice machine produces ice with the descaler and
sanitizer solutions
• All ice produced during the descaling and sanitizing
procedures must be discarded
Heavily Scaled Descaling Procedure
Perform this procedure if you have some or all of these
symptoms.
• Grinding, popping or squealing noises from the
evaporator
• Grinding noise from gearbox
• 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
Run a descaling procedure as described above after this
procedure is complete.
NOTE: A Sanitizing Procedure must be performed after all
descaling procedures have been completed.
