How To Use This Manual
Cornelius provides this manual as an aid to the service technician in installation, operation, and
maintenance of the CCM/CCU Series (electro-mechanical) cube ice machines. If used properly
this manual can also assist the service technician to troubleshoot and diagnose most of the
problems that may occur with the machine.
The first two sections of this manual provide general information and maintenance information.
The remainder of the manual beginning with Section C provides troubleshooting and service
information. Section C contains flow charts called troubleshooting trees. Page C-1 provides
instructions on using the troubleshooting trees. Each troubleshooting tree is named to describe
a particular problem with the operation of the machine.
When following the troubleshooting trees, the service technician will be led through questions
and checks and end up with a probable solution. When using the troubleshooting trees, it is
important that the service technician understand the operation and adjustments of the
components being checked and the component suspected of malfunctioning. A detailed
description of the operation and adjustments of the components as well as other service
information is available in the pages that follow Section C.
Sections D, E, and F focus on a particular system in the ice machine: water distribution system,
refrigeration system, and it is important that these sections be used together with the
Troubleshooting Trees in Section C.
