Ice Machines require periodic maintenance to be able to deliver like-new reliable performance.
Schedule: Typically twice per year for scale removal and sanitizing. At some sites the water supply to the ice machine will contain significant quantities of minerals, and that will result in a water system becoming coated with these minerals, requiring more frequent maintenance than twice per year.
Note: Due to the small amount of water draining from the machine, we recommend regular sanitizing of the drain system. This can be achieved by repeating step 15
