Replacing The Filter Transformer Or Filter Relay - Frymaster FPRE117 Installation, Operation, Service, And Parts Manual

4. Loosen the nut and bolt that secures the bridge to the oil-return manifold.
5. Remove the cover plate from the front of the motor and disconnect the motor wires.
6. Unplug the pump motor assembly 6-pin connector C-2 and, using a pin pusher, disconnect the
vent vacuum-breaker solenoid (pins 2 and 5) that is attached to the oil return manifold.
7. 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. Undo
the single nut holding it in place in back. Be careful not to let the rear of the bridge slip off the
manifold at this point.
8. 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.
9. 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 1 and 4 of the 6-pin connector C-2; the vent vacuum-breaker solenoid valve
wires go in positions 2 and 5; the red/black heater tape wires go into position 3 and the
violet/white wires go into position 6 (see illustration below).
10. 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 rear flush port.)
11. When proper operation has been verified, reinstall the back panels and the filter pan and lid.
12. Reposition the fryer under the exhaust hood and reconnect it to the electrical power supply to
return the fryer to service.
