8. Unplug the 15-pin connector from the rear of the left component box and, using a pin pusher,
disconnect the solenoid valve wires (pins 4, 6, 10 and 12). NOTE: If the vacuum-breaker
solenoid valve is connected to the manifold rather than the pump, its wires (pins 4 and 6) do not
need to be disconnected.
9. Remove the two nuts and bolts that secure the front of the bridge to the cross brace and carefully
slide the bridge rearward off the cross brace until its front end can be lowered to the floor. Be
careful not to let the rear of the bridge slip off the manifold at this point. NOTE: In some early
production units, the bridge will not slide far enough to the rear to clear the front brace. In such
cases, the front brace must be removed. It is held in place by two hex head screws on each end
and a nut and bolt inside the brace near each end.
10. Get a good grip on the bridge, carefully pull it forward off the oil-return manifold, and lower the
entire assembly to the floor. Once on the floor, pull the assembly out the front of the fryer.
11. When required service has been completed, reverse steps 6-12 to reinstall the bridge. NOTE:
The black motor wires go on the top terminal, the white on the bottom. The pump solenoid valve
wires go in positions 10 and 12 of the 15-pin connector; the vacuum-breaker solenoid valve
wires go in positions 4 and 6. In both cases, polarity does not matter.
12. Once the bridge is back in place, reverse steps 4 and 5 to reinstall the contactor boxes.
13. Reconnect the unit to the electrical power supply, and verify that the pump is functioning
correctly (i.e., when a filter handle is placed in the ON position, the motor should start and there
should be strong suction at the intake fitting and outflow at the power shower or rear flush port).
14. When proper operation has been verified, reinstall the back panels and the filter pan and lid, and
return the fryer to service.
7.8.3 Replacing the Filter Transformer or Filter Relay
Remove the left controller from the fryer to expose the interior of the left component box. The filter
transformer and relay are located as shown in the illustration below. NOTE: The right component
box is identical to the left except that the filter transformer and relay are not present.
