Replacing the Selector Valve Motor Encoder

Fryers with serial numbers after NE1707001 will have selector valve for each vat plumbed into the oil return lines.

The selector valve applies to all Del Taco fryers.

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

1. Remove right side panel.

   

2. Disconnect both the selector valve 24VDC motor connection and the AIF communication harness at the AIF board.

   

3. Remove 3 button head cap screws (1) .

4. Separate old motor encoder assembly (2) from selector valve (3).

5. Connect both harnesses from new motor encoder assembly to AIF board.

6. Power up fryer to let valve find home position. Selector valve calibration occurs automatically upon power up.

7. Turn selector valve so that new motor encoder spool alignment indicators center over port 10.

   SHOCK HAZARD Manually rotating the motor encoder assembly may cause damage to the motor. If manual rotation is required for proper alignment, only manually rotate selector valve.

8. Align spool coupler (4), valve, and motor encoder assembly, and then seat motor encoder assembly on valve.

9. Replace 3 button head cap screws.

10. Connect AIF communication wire harnesses to AIF board.

11. Test selector valve by running calibration. Enter INFO Mode and refer to Pumps and Valves for calibration instructions. Successful calibration is 2.00R 10P E/R2000 +/- S

12. Install right side panel.
