Detailed Cleaning and Sanitizing
General
You are responsible for maintaining the ice machine
in accordance with the instructions in this manual.

Descale and sanitize the ice machine a minimum of once
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. An extremely
dirty ice machine must be taken apart for descaling and
sanitizing.

are the only products approved for use in Manitowoc ice
machines.
