minimum of 45 minutes.
The final phase of the Heat Treatment Cycle is the
cooling phase. The freezer must cool the mix below 41°F
(5°C) within 120 minutes.
When the entire Heat cycle has been completed, the
machine will enter the Storage mode. The machine can
be placed in Auto or left in Storage.
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. Please consult your governing
health codes 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 will cause the control to lock the
freezer out of the Auto mode.
Always comply with local health codes for the maximum
number of days allowed between brush-clean cycles.

Freezer Locks

There are two types of freezer lock conditions that can
occur: hard lock or soft lock:
• Hard lock requires the machine be disassembled
and brush-cleaned.
• Soft lock can be corrected by either disassembling
and brush-cleaning the machine or by starting
another Heat Treatment Cycle.
Hard Lock
The machine will hard lock if either the brush-clean timer
has elapsed or if a thermistor failure (freezing cylinder or
hopper) occurs during the Heat cycle.
The following screen will be displayed if a brush-clean
cycle time has occurred:

Figure 5-5
If the machine has hard locked and an attempt is made to
enter the Auto mode, the machine will remain in the
Standby mode and will not allow any dispensing.
The WASHING REQUIRED message will remain on the
display until the brush-clean requirements are fulfilled. To
reset the hard lock, turn the main power switch OFF for at
least 5 minutes and disassemble the freezer for the
cleaning procedure.
Soft Lock
When a Heat Treatment Cycle has not been initiated
within the last 24 hours, a soft lock failure will occur. A
soft lock allows the operator to correct the cause of the
soft lock. The operator has the option of either starting
another Heat cycle or brush-clean the machine. When a
soft lock occurs, the machine will go into Standby mode.
The message FREEZER LOCKED - HEAT TREAT
REQUIRED is displayed on the screen. The reason for
soft lock is indicated in the Lockout History in the
Manager's Menu (SEL button).
When the reason for the soft lock has been corrected,
selecting Heat Cycle button initiates a Heat cycle
immediately.
A soft lock can also occur any time during operation
when the hopper or barrel temperature rises above 59°F
(15°C), the temperature rises and remains above 45°F
(7°C) for more than 1 hour, or the temperature rises and
remains above 41°F (5°C) for more than 4 hours.
If a product over temperature condition occurs during
operation, the message FREEZER LOCKED - HEAT
TREAT. REQUIRED is displayed on the screen.
When one of these messages appears, automatic freezer
operation cannot take place until the freezer is
disassembled and brush-cleaned, or has completed a
Heat Treatment Cycle.
Note: A record of Heat Cycle Data and Lockout History
can be found in the Manager's Menu (SEL button).
