CLEANING and SANITIZING

A Scotsman Ice System represents a sizable investment of time and money in any company's
business. In order to receive the best return for that investment, it MUST receive periodic
maintenance.
It is the USER'S RESPONSIBILITY to see that the unit is properly maintained. It is always preferable,
and less costly in the long run, to avoid possible down time by keeping it clean; adjusting it as needed;
and by replacing worn parts before they can cause failure. The following is a list of recommended
maintenance that will help keep the machine running with a minimum of problems.
Maintenance and Cleaning should be scheduled at a minimum of twice per year.
Sanitizing of the ice storage bin should be scheduled for a minimum of 4 times a year.
Electrical power will be ON when doing in place
cleaning.
