WARNING!
DO NOT
attempt to draw product or
disassemble the machine during the Heat Treatment
Cycle (if equipped). The product is hot and under
extreme pressure. Severe burns from hot product may
result if this instruction is not followed.
In the Heat cycle, the mix temperature in the hopper and
freezing cylinder must be raised to 151°F (66.1°C) within
90 minutes.
When the heating phase is complete, the machine goes
into the holding phase of the cycle. The holding phase
will keep the temperature above 151°F (66.1°C) for a
minimum of 35 minutes.
The final phase of the Heat Treatment cycle is the cooling
phase. The machine must cool the mix below 41°F (5°C)
within 120 minutes.
When the entire Heat cycle has been completed, the
Heat key will no longer be illuminated. The machine will
enter the Standby mode (Standby key illuminates). The
machine can be placed in Auto or left in Standby.
To comply with health codes, Heat Treatment system
machines must complete a Heat Treatment cycle daily
and must be disassembled and brush-cleaned according
to the frequency specified by your federal, state, or local
regulatory agencies. Please consult your governing food
code to determine the maximum number of days allowed
between brush-clean cycles.
Brush-cleaning is the normal disassembly and cleaning
procedure found in this Operator’s Manual. Failure to
follow these guidelines will cause the control to lock the
machine out of the Auto mode.
If the Heat Treatment cycle fails, the screen will display a
failure message and return the machine to the Standby
mode.
Always comply with local guidelines for the maximum
number of days allowed between brush-clean cycles.
Freezer Locks
There are two types of machine lock conditions that can
occur: hard lock or soft lock. A hard lock requires the
machine to be disassembled and brush-cleaned. A soft
lock can be corrected by either disassembling and
brush-cleaning the machine or by starting another Heat
Treatment cycle.
Hard Lock
There are two causes of a hard lock failure. The machine
will hard lock if either the Brush-Clean Timer has elapsed
or a thermistor failure (freezing cylinder or hopper)
occurred during a Heat cycle.
•
The following screen will be displayed if a Brush
Clean Cycle Time has occurred:
Pressing the SEL key will display the following
screen:
•
The following screen will display if there has been a
thermistor failure (freezing cylinder or hopper) during
the Heat Treatment process:
Pressing the SEL key will indicate which thermistor
caused the hard lock.
If the machine has hard locked and an attempt is
made to enter Auto mode, the machine will enter the
Standby mode and display the following message:
