FryerComponentsOperation
The SE fryer components function in specific order of operation. Knowing and understanding the sequence of
fryer and components operation enables you to diagnose equipment failure more accurately.
HeatingSystem
The unit is connected to line voltage:
If Fuse F1 on the relay board is good:
The A.C. indicator is illuminated.
The controller is supplied with 24 VAC.
With the drain valve handle closed, the proximity switch supplies 24 VAC to the drain valve interlock
(DVI) input at the controller.
24 VAC is at the Side On (SO) relay COM contact.
The controller is turned ON:
The SO indicator on the relay board is illuminated.
The SO relay is energized, closing the circuit.
The safety (SO) contactor energizes if the hi-limit is not tripped.
With the roll out switch and hi-limit in the closed position, the ignition module receives 24VAC at
terminal 6 (24 VAC).
Hi‐LimitSystem
If the hi-limit trips:
The SO and HD contactors lose 24 VAC supply and the HFB loses 24 VAC.
The computer displays “HEATING”.
The HD lamp is illuminated on the Back-up T-stat and the HFB lamp is not illuminated.
After the hi-limit resets (unit cools to 375°F ±20°F (191°C ±20°C)), turn the controller off and then back on
for the unit to heat.

FilterSystem
Opening the RED return valve handle, does the following:
Opens the return valve to that vat.
Closes the pump proximity switch causing the “pump run” relay to be energized.
Starts the pump motor.
Closing the return valve handle de-energizes the relay and the pump motor stops running and the return valve
closes.
The pump system is equipped with a circuit breaker which de-energizes the system and the heat tape in the
event of over current. The circuit breaker must be in the “ON” position for the pump and heat tape to operate.
NOTE: Circuit Breaker should remain in the “ON” position at all times.
The return piping system may be provided with optional heat tape to prevent solidification of solid
shortening. The heat tape is low wattage and is on constantly to maintain liquid shortening in the line.
