The electric fryer requires two switching contactors:
a primary
contactor and a heat contactor. The primary contactor
energizes (contacts close) any time the Power/Pump Switch
is in the “Power” position and the temperature of the pot is
below 420°F (215OC). The hi limit will cut the power at the
primary contactor if temperatures in the cookpot exceed 420° F
(215O 6). The primary contactor supplies power to one side of
the heat contactors.
The heat contactor is controlled by the computer controller.
en the controller calls for heat, the heat contactor applies
power to one side of the heating elements. When the heat
contactor and the primary contactor are energized (contacts
closed), the electric heating elements heat the shortening.
