Electronic Temperature Control (Domestic)
Operation
The temperature control is factory set to stop the power to the kettle when the thermocouple
reaches set point. This is also the ideal point to dump the popped corn out of the kettle. On the
first start-up, this is the ideal time to load the corn and oil. Therefore, if the Kettle Heat Switch is
turned ON, the yellow light and buzzer are ON,
one
of the following actions should be taken:
•
Load the corn and oil or
•
Dump the popped corn from the kettle or
•
Turn OFF the Kettle Heat Switch if you are finished popping corn.
