The final phase of the Heat Treatment cycle is the cooling
phase. The freezer must cool the mix below 41°F (5°C)
within 90 minutes for UVC3 units, or 120 minutes for
UVC4 units.
When the entire Heat cycle has been completed, the
Heat cycle key is no longer illuminated. The machine
enters the Standby mode (Standby key illuminates). The
machine can be placed in Auto mode or left in Standby
mode.
To comply with health codes, heat treatment system
freezers
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. 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 the Operator’s Manual. Failure to
follow these guidelines causes the control to lock the
freezer out of the Auto mode.
If the Heat Treatment cycle fails, the screen displays a
failure message and returns the freezer to the Standby
mode.
Always comply with local guidelines for the maximum
number of days allowed between brush-cleaning.
Freezer Locks
Two types of freezer lock conditions 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 freezer
hard locks if either the brush-clean timer has elapsed or a
thermistor failure (freezing cylinder or hopper) has
occurred during a Heat cycle.
•
The following screen appears if a brush-clean cycle
time has occurred:
Pressing the SEL key displays the following screen:
•
The following screen appears if there has been a
thermistor failure (freezing cylinder or hopper) during
the Heat Treatment process:
Pressing the SEL key indicates which thermistor caused
the hard lock.
If the machine has hard locked and an attempt is made to
enter Auto mode, the machine enters the Standby mode
and displays the following message.
To restore the message that identified the reason for the
hard lock, turn the power switch off for 5 seconds and
then return the power switch to the ON position. The
original message with the reason for the hard lock
appears.
The FREEZER LOCKED message remains on the
display until the brush-clean requirements are fulfilled.
The freezer must be disassembled to activate the
5-minute timer on the display screen. Once the timer
counts down to zero, the lockout is cleared.
