Introduction

intended to provide you, and the maintenance or
service technician, with the information needed to
install, start up, clean, maintain and repair this

The CME250 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 CME250 automatically maintains the
level of ice by turning on when the ice level falls,
and switches off when the bin is full.
The refrigeration system uses HP62 as the
refrigerant. HP62 models use polyolester
refrigerant oil.
Information on HP62 is located on page 23.
