Introduction:
This product manual contains the information
needed for the setup, installation, initial start up,
sanitation and maintenance of this ice machine.
Keep it for future reference.
All series of these 4 models are covered in this
manual:
•
CME256, a 115 volt, single evaporator
machine
•
CME506, a 115 volt, dual evaporator
machine (115 volt if 60 Hz, 230 volt if 50 Hz)
•
CME656 and CME806, 230 volt, dual
evaporator machines
Be certain that the information applies to the model
in question. If no model is listed, the information
applies to all models, including A through F series.
This manual is organized in the same way as the
expected use of the machine, it begins with
specifications, goes thru unpacking and setup,
shows where everything is; continues with initial
start up, then describes how it works. After that is
the sanitation section, followed by service
