Replacing the Flange Filter Pump and Motor Assembly

The two most common causes for a fryer not to pump oil are that the pump is clogged, or the thermal overload switch has been tripped on the motor. The pump and motor is located on the rear of the fryer.

To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.

Resetting Thermal Overload Switch

1. Locate the pump and motor in the rear of the fryer and if the motor is hot, allow it to cool for about 5 minutes.

   

2. Since it takes some effort to reset the switch, use a tool, such as a crosshead screwdriver, to press against the reset button until a “click” is heard.

Removing Debris from Pump

1. Loosen the four Allen head screws on the end of pump and remove the cover. (Removing the bottom rear panel may help in accessing the set screws.)

   

2. The inside is now exposed leaving a rotor and five Teflon rollers. Clean the rotor and rollers.

   NOTICE -

   For proper operation, align the indicators on each half of the pump.

3. To reassemble, place rotor on drive shaft, and place roller into rotor.

   NOTE: A small amount of grease might be needed to hold the bottom roller into place until cover plate is put on. Make sure O-ring is in proper position on plate.

Replacing the Filter Pump and Motor

The following procedure only applies to units with serial numbers prior to BH1810136. For units with serial numbers after BH1810136, entire pump assembly must be replaced.

1. Remove the bottom, rear panel and the right side panel.

   

2. Using a 5/8” wrench, loosen the front, flexible line fitting, on the pump.

3. Using a 1” wrench, loosen the rear pump fitting.

4. Locate the appropriate conduit on right side of the unit and disconnect the conduit from the fryer.

   

5. Using a 1/2 in. wrench, remove 4 bolts securing motor to motor bracket and pull pump and motor assembly from fryer.

6. Using a 1/2 in. wrench, remove the 2 bolts securing pump to the motor and pull the pump from the motor.

7. Install a new seal kit (part no. 17476) onto shaft of motor.

8. Align the shaft of motor with the rotor on the inside of the pump and push pump onto shaft of motor.

9. Secure the pump onto the motor with the 2 bolts.
