Manitowoc's Cleaning Technology

Manitowoc CNF0201 - CNF0202 Ice Machines allow the
initiation and completion of a cleaning cycle at the flip of
a switch. This cycle will permit descaling or sanitizing 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 a remedial cleaning procedure
between the 6-month detailed descaling and sanitizing
procedure. This remedial cleaning procedure removes
mineral build-up from the evaporator, which results in
peak efficiency and lower operating costs.
This technology allows initiation and completion of a
cycle, after which the ice machine automatically starts ice
making again.
There are three separate procedures.
Heavily Scaled 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 trips speed sensor.
A Detailed Descaling/Sanitizing Procedure must be
performed after this procedure.
