Models C709 & C717 Important: To the Operator
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.
HOT PRODUCT
Figure 15
DO NOT attempt to draw product or
disassemble the unit during the HEAT cycle. The
product is hot and under extreme pressure.
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 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 35 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 90 minutes.
When the entire heat cycle has been completed, the
HEAT symbol
will no longer be illuminated. The
machine will enter the STANDBY mode (STANDBY
symbol
illuminates). The machine can be placed
in AUTO or left in STANDBY.
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 25.)
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 16.)

Freezer L o cks
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.
Hard Lock: There are two causes of a hard lock
failure:
1. The brush clean timer has elapsed
(maximum setting of 14 days).
