Remove Locking Knob and handle. Set aside for reinstallation later. 2. Remove four (4) screws from the valve. Refer to the image on page 2 (mounting positions) to determine which screws to remove. 3. On the back side of the actuator, align the smallest slot on the actuator shaft with the smallest slot on the valve diverter. 4. With the two shafts engaged rotate the actuator until holes on the actuator align with the screw holes on the cover. 3 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
