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.
Standard Heat Control Adjustment
The machine comes from the factory preset to achieve a finished
Product Cook Temperature
of
280°F. Small adjustments may need to be made for mix used or cooking conditions. If the mix is
ready, either before or after the buzzer sounds, then follow the steps listed to adjust the cook
temperature of the unit:
Note:
The sound of the buzzer signals kettle heat shut-off.
1.
Remove the silver hole plug located on the front panel of the control box to access the
heat control’s potentiometer adjustment.
2.
Turn the potentiometer slightly clockwise to increase the temperature, or
counterclockwise to decrease the temperature.
Standard 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 Standard Heat Control Adjustments), the unit is ready for use and
should not need calibration.
To reset the Standard Heat Control back to factory settings follow the procedure shown below.
Note:
For calibration purposes only, corn oil is used to determine the Standard 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.)
5.
Turn the Motor Only Switch ON to stir the oil while it heats.
6.
When the oil reaches 335°F, slowly turn the potentiometer counterclockwise until the
buzzer sounds. If buzzer sounds before the temperature reaches 335°F, turn the
potentiometer clockwise until buzzer stops and continue to turn an additional 1/8 turn.
Note:
The sound of the buzzer signals kettle heat shut-off.
7.
Allow oil to cool below 300°F, then repeat Step 5 to check the buzzer sounds at 335°F.
8.
The unit is now calibrated for the heat control buzzer to sound at a finished product
temperature of 280°F.
Caution:
Allow hot oil to cool below 140°F before attempting to drain.
