Cleaning Ice Making System - Sub-Zero 315I Technical Service And Parts Manual

Model 315I (UC Ice Maker)
Cleaning the Ice Making System
Though the water system flushes away mineral impurities during the harvest cycle, some impurities will inevitably
remain, sticking to parts of the ice machine, causing malformed ice cubes. This build up of mineral scale can short-
en the life of the unit.
To keep the ice machine operating properly, these impurities or minerals will have to be dissolved regularly with ice
machine cleaner. (Sub-Zero part #19034306)
