Digital Heat Control Adjustment/Calibration
Product Cook Temperature is the actual temperature of the PRODUCT (Caramel Corn Mix); this
is measured with an accurate candy thermometer. Infrared temperature readers are NOT
recommended.
Set Point Temperature is the temperature setting of the KETTLE; this is the temperature
needed to get the Caramel Corn Mix up to the finished Product Cook Temperature of 280°F. The
digital display shows the kettle temperature, NOT the product temperature.
Note: The Set Point Temperature will be higher than the product temperature.
Refer to the candy thermometer for accurate product temperature.
Digital Heat Control Adjustment
The machine comes from the factory preset to achieve a Product Cook Temperature of 280°F.
Small adjustments may need to be made for mix used or cooking conditions. If the product is
ready, either before or after the buzzer sounds, then follow the steps listed to increase or
decrease the Set Point Temperature of the kettle:
Note: D Models - The sound of the buzzer signals kettle heat shut-off.
DT Models – The sound of the second buzzer signals kettle heat shut-off.
1. To change the Set Point Temperature, press the key. The display shows SP
followed by a temperature number flashing. Use the arrow keys to set the desired
temperature.
2. Once the temperature is set, press the key to lock in the new temperature.
Digital Heat Control Calibration (Performed at the Factory)
This unit has been calibrated at the factory. Other than small adjustments made for mix used or
cooking conditions (see above Digital Heat Control Adjustment), the unit is ready for use and
should not need calibration.
To reset the Digital Heat Control back to factory settings follow the procedure shown below.
Note: For calibration purposes only, corn oil is used to determine the Digital Heat Control
temperature setting which will produce an accurate finished product temperature
of 280°F.
1. Start with a clean unit, which is cool before attempting to calibrate.
2. Fill the mixing bowl with a one inch depth of corn oil.
3. Turn the Heat/Motor Switch ON.
4. Use an accurate candy thermometer to measure the temperature of the oil in the
mixing bowl. (Infrared temperature readers are NOT recommended.)

bushings with white food grade Never Seez®ONLY, then reinstall the shaft.
To remove the shaft, loosen the (2) socket head cap screws in the jaw coupling,
then remove the shaft. DO NOT lose the shaft key, it must be reset into place.
7. Lightly lubricate the center hub of the kettle with a small amount of Petro Gel to allow
for easy installation of the hub seal assembly.
8. Slide the new hub seal assembly down the agitator shaft. Apply pressure to ease the
assembly over the center hub of the kettle until it seats properly (see image below).
9. After installing the hub seal, re-install the mix paddles.
Note: Make sure the plunger of each paddle securely sets into its hole in the shaft.
10. Rotate the shaft by hand to make sure the paddle does not touch the kettle bottom;
re-adjust shaft if needed.
