Preventative
Maintenance
Manitowoc recommends a Factory Authorized Service company or Distributor Authorized Service Dealer perform thorough
preventative maintenance prior to restoring service of the Manitowoc ice machine, storage bin or dispenser. Section 4
(Maintenance) of the Installation, Operation and Maintenance manual should be followed to ensure proper cleaning and
sanitizing steps are completed.
Water system components including the water inlet valve, water pump and dump valve may require removal for inspection
or replacement depending on the potable water quality and the length of time the components had no use. Water cooled ice
machines may require the condenser be cleaned and the refrigeration water regulating valve evaluated for proper performance.
This is also a good time to replace water filtration, replenish AuCS chemical and replace the Luminice bulb if these Manitowoc
accessories are used.
