CCC-20 Component Description & Function
Head Assembly: It is the main assembly which consists of the following electrical components: heating element, power cord,
power switch, thermostat, safety interlock switch, terminal block, & indicator light.
NOTE: The heating element will not operate if the head assembly is not properly seated onto the pan, or is being
operated without the pan.
Power Switch: Double Pole Single Throw, turns the voltage On or Off to the unit’s internal components.
NOTE: The built in led illuminates when line voltage is present into & out of the switch. If not lit, it normally
indicates that the safety interlock switch is not be depressed. The head assembly should be removed & reinstalled onto
the pan.
Splash Guard: A clear PVC boot that fits over the face of the power switch. It is used to help prevent water/moisture from
entering & damaging the power switch & electrical components within the electrical compartment.
NOTE: The PVC boot must always be used. Failure to do so may result in water/moisture damage to electrical
components.
Safety Interlock Switch: A normally open (N.O.) momentary switch that is 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.
Safety Interlock Switch O’ring: An o’ring that fits over the plunger of the switch. It helps prevent water/moisture from
entering & damaging the safety interlock switch & electrical components within the electrical compartment.
NOTE: The o’ring must always be used. Failure to do so may result in water/moisture damage to electrical
components.
Terminal Block: A three pole, six terminal junction block. It links the incoming power cord wires (L1, N, Ground) to the safety
interlock switch, power switch, & chassis ground.
Heating Element: It is an “M” shape element that is attached to the head assembly & is positioned at the bottom of the pan.
It heats the water until it is cycled off by the thermostat.
