Model 428 Operati ng Procedures
Section 6 Operating Procedures
The Model 428 freezer is designed to produce shake
or slush product at the desired thickness. This unit
has a 7 quart freezing cylinder.
We begin our instructions at the point where we
enter the store in the mor ning and find the part s
disassembled and laid out to air dry from the
previous night’s brush cleaning.
These opening procedures will show you how to
assemble these part s into the freezer, sanit ize them,
and prime the freezer with fr esh mix in preparat ion
to serve your first portion.
If you are disassembling the machine for the first
time or need info rmation to get to this point in our
instructions, turn to page 26, “Disassembly”, and
start there.
