When the power switch is placed in the ON position, the
control panel touch keys become operative. The VFD will
be either blank or indicate that the machine has been
cleaned. (See Figure 175.)
Figure-175
Display for International Models Only
Some international models will continuously display the
temperature of each mix hopper when the power switch
is in the ON position. (See Figure-176.)

Heat Cycle
The Heat symbols on the control panel are
illuminated throughout the Heat Treatment cycle. Two
warning messages will be displayed on the screen: DO
NOT DRAW will be displayed when the mix temperature
is below 130
°
F (54.4
°
C). (See Figure-177.)
Figure-177
When the temperature of the mix is above 130°F
(54.4°C), the screen will display a message indicating
that HOT PRODUCT is in the machine.

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 hoppers and
freezing cylinders must be raised to 151
°
F (66.1
°
C)
within 90 minutes.
When the Heating phase is complete, the freezer 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 30 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 2 hours.
When the entire Heat cycle has been completed, the
Heat symbols will no longer be illuminated. The
machine will enter the Standby mode (Standby symbols
and illuminate). The machine can be placed in
Auto mode or left in Standby mode.
Heat Cycle Failure Messages
To comply with health codes, Heat Treatment system
freezers
must complete a Heat Treatment cycle daily
and must be disassembled and brush-cleaned a
minimum of every 14 days. Brush-cleaning is the normal
disassembly and cleaning procedure found in this
manual. Failure to follow these guidelines will cause the
control to lock the freezer out of the Auto mode.
Always comply with local guidelines for the maximum
number of days allowed between brush-clean cycles.
(See the Manager's Menu for setting the brush-clean
interval on page 78.)
If the Heat Treatment cycle fails, the VFD will display a
failure message and return the freezer to the Standby
mode. A
lock is defined as a special Standby mode of
operation, which does not allow the machine to operate
in the Auto mode.
There are two types of freezer lock conditions that can
occur: hard lock or soft lock. A hard lock requires the
machine 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.
