Daily Closing Procedures
THIS PROCEDURE MUST BE PERFORMED
ONCE EVERY 24 HOURS.
The function of the Heat Treatment Cycle is to destroy
bacteria by raising the temperature of the mix in the
freezing cylinder and the hopper to a specified
temperature for a specified period of time, and then
bringing the temperature back down low enough to
retard spoilage.
The Heat Treatment Cycle will start at the time
designated in the Auto Heat Time.
DO NOT draw product or attempt to
disassemble the unit during the HEAT cycle. The
product is hot and under extreme pressure.
Important: The level of mix in the mix hopper must be
above the mix low probe. (The mix low light must not
be on.)
Shake Side
Note: If the CLEAN MANUALLY light is flashing, do
not add mix. The machine must be disassembled and
brush cleaned within 24 hours.
Both sides of the freezer must be in the AUTO mode
before the HEAT cycle may be started.
