ELECTRICAL OPERATION
COMPONENT FUNCTION
FRYER CONTROLS
Control Thermostat . . . . . . . . . . .
Regulates shortening temperature at the selected set point. Temperature
range from off to 200
/
F thru 400
/
F.
Thermopile . . . . . . . . . . . . . . . . . .
When heated by the pilot burner flame, generates DC millivolts to
energize pilot valve coil and main valve coil on the gas combination valve.
Gas Combination
Valve . . . . . . . . . . . . . . . . . . . . . . .
Allows gas flow to the pilot when pilot valve coil is energized; and gas flow
to the main burners when main valve coil is energized. Also, regulates the
gas manifold pressure.
High Limit Thermostat . . . . . . . . .
Prevents the shortening from reaching temperatures over 465°F (auto
reset).
KLEENSCREEN FILTER CONTROLS
Filter Power Switch . . . . . . . . . . .
Supplies 120VAC to pump motor. Filter valve switch or discard valve
switch must be closed (valve handle extended).
Pump Motor . . . . . . . . . . . . . . . . .
Operates pump to circulate shortening through filtering system.
Filter Valve Switch . . . . . . . . . . . .
Energizes pump motor to filter the shortening when the N.O. switch
contacts are closed (valve handle extended); and filter power switch is
turned on.
Discard Valve Switch . . . . . . . . . .
Energizes pump motor to discard the shortening from filter tank when the
N.O. switch contacts are closed (valve handle extended); and filter power
switch is turned on.
