  • Page 13: Built-In Filtration System Service Procedures

    1.8 Built-in Filtration System Service Procedures 1.8.1 Filtration System Problem Resolution One of the most common causes of filtration problems is placing the filter paper on the bottom of the filter pan rather than over the filter screen. CAUTION Ensure that filter screen is in place prior to filter paper placement and filter pump operation.
  • Page 14 Disconnect power to the filter system, remove the input plumbing from the pump, and use a screwdriver to manually turn the gears. ● Turning the pump gears in reverse will release a hard particle. ● Turning the pump gears forward will push softer objects and solid shortening through the pump and allow free movement of the gears.
  • Page 15 6. Disconnect the pump suction flexline at the filter pan connection end. Disconnect pump suction flexline here. 7. Remove the cover plate from the front of the motor and disconnect the motor wires. 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).
  • Page 16 14. When proper operation has been verified, reinstall the back panels and the filter pan and lid, and return the fryer to service. 1.8.3 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.
