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.
