TECHNICAL THEORY OF OPERATION
When the unit is plugged into the outlet, line voltage flows to the normally open (N.O.) safety interlock switch*. Once its
contacts close, line voltage then flows to the input side of the power switch. When the power switch is turned on, line
voltage then flows to a normally closed (N.C) capillary bulb style thermostat**. Providing the water temperature within
the pan is below 162° F (72° C), the thermostat** calls for heat by supplying line voltage to the heating element***. As
the water begins to heat up, the thermostat’s bulb monitors the water temperature. When the water temperature
approaches approximately 162° F (72° C), the thermostat’s contacts open up & turn off the heating element***.
Simultaneously, the “Green” indicator light**** will light up to indicate the water is up to temperature. The heating circuit
will cycle on & off as needed, even at idle. If the heating circuit continues to call for heat, the water will begin to boil &
overcook the corn.
NOTE: If this condition should arise, the root cause must be determined & corrected.
* Safety Interlock Switch: Used to prevent operation of the heating element in the event the head assembly is not
properly seated onto the pan, or is being operated without the pan. The switch has an actuating plunger which protrudes
from beneath the head assembly. Provided the head assembly is properly seated onto the pan, the weight of the head
assembly allows the plunger to become depressed, therefore closing its contacts.
** Thermostat: The thermostat is fixed to maintain approximately 162° F (72° C) water temperature.
*** Heating Element: The element must only be operated while submersed in water.
**** CCC-20 (Mfg # 9600214) uses an “Amber” colored indicator light. It lights up when the heating element is on. It turns
off when the heating element is off. When off, it indicates the water is up to temperature.
