Scotsman Ice Maker 600LB CM3 30inW Commercial Cubed Machine

CM500 Introduction To the owner or user: This service manual is intended to provide you, and the maintenance or service technician, with the information needed to install, start up, clean, maintain and repair this product.

The refrigeration system uses R-502 as the refrigerant.

The CM500 is an ice machine that produces cubed ice on 2 vertical cube freezing surfaces. The cubes fall as vertical strips of cubes into the ice storage bin where they break up into individual cubes. The CM500 automatically maintains the level of ice by turning on when the ice level falls, and switches off when the bin is full.
