1.13.3 Replacing an AIF (Automatic Intermittent Filtration) board
Disconnect the fryer from the electrical power supply. Locate the AIF board to be replaced under a
frypot. Mark and unplug the harnesses. The AIF board assembly is held in place with one screw in the
front of the assembly (see Figure 12). Remove the screw and the front of the assembly drops down
(see Figure 13) and the back tab slides out of the bracket attached to the frypot (see Figure 14).
Reverse steps to reassemble, ensuring that the new AIF assembly slides into the slot in the rear of the
bracket.

1.13.4 Replacing an Actuator
Disconnect the fryer from the electrical power supply. Locate the actuator to be replaced under a
frypot and mark and unplug the actuator. The actuators are held in place by two clevis pins which are
held in by cotter ring pins (see Figure 15). Remove both clevis pins and remove the actuator. Attach
the new actuator with only the rear clevis pin and cotter ring pin (see Figure 16). Rotate the actuator
shaft until the holes of the shaft and valve plate align. Insert the second clevis pin and cotter ring pin
to secure.
Ensure the replacement return valve is positioned correctly by filtering a vat of oil on a vat other than
the vat with the new valve. If bubbles appear in the vat with the new valve, further adjustment of the
actuator or valve is necessary. Take out the pins and adjust the valve until no bubbles are present in
the vat. Reinsert the pins to secure the actuator.
