Manitowoc’s Cleaning Technology
Manitowoc Flake/Nugget Ice Machines include
technology that allows the initiation and completion of a
cleaning cycle at the flip of a switch. This cycle will
permit cleaning of all surfaces that come in contact with
the water distribution system. Periodic maintenance
must be performed that includes sanitizing the bin and
adjacent surface areas, which are not contacted by the
water distribution system.
Depending on local water conditions Manitowoc
recommends initiating preventative maintenance
cleaning procedures between the 6 month cleanings.
This preventive maintenance removes mineral build-up
from the evaporator, which results in peak efficiency and
lower operating costs.
This technology allows initiation and completion of a
clean cycle, after which the ice machine automatically
starts ice making again.
This Manitowoc Ice Machine has three separate
cleaning procedures.
Preventative Maintenance Cleaning Procedure
Perform this procedure as required for your water
conditions. Recommended monthly.
• Allows cleaning 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).
Cleaning/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
cleaned and sanitized
• The ice machine produces ice with the cleaner and
sanitizer solutions
• All ice produced during the cleaning and sanitizing
procedures must be discarded
Heavily Scaled Cleaning 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 cleaning procedure as described above after this
procedure is complete.
NOTE: A Sanitizing Procedure must be performed after
all cleaning procedures have been completed.
