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.
Be certain that the information applies to the
model in question. If no model is listed, the
information applies to all models.
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 diagnosis
and repair.
