Use the up or down arrow symbol to move the cursor to “YES”. Touch the SEL symbol to immediately start a heat cycle.
Note: The machine must be in AUTO or STANDBY and have sufficient mix in the hopper before the machine can successfully enter the HEAT mode of operation.
Heat Cycle
The HEAT symbol on the control panel is 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).
DO NOT DRAW
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
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 for UVC3 units or 120 minutes for UVC4 units.

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 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 the Operator Manual. Failure to follow these guidelines will cause the control to lock the freezer out of the AUTO mode.
If the Heat Treatment Cycle fails, the screen will display a failure message and return the freezer 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 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.
Hardlock
There are two causes of a hard lock failure. The freezer will hardlock if either the Brush Clean Timer has elapsed or if a Thermistor Failure (Freezing Cylinder or Hopper) occurred during a Heat cycle.
1.The following screen will be displayed if a Brush Clean Cycle Time has occurred.
