1. Turn the shower knob or handle all the way to the left shutting off the water. Check the shower knob cap for a screw underneath or look at the handle's side round setscrew. The particular model's construction determines which tool to use.
2. Pop off the Delta knob cap to extract the screw underneath. If your model does not have a cap and screw, use an Allen wrench to loosen the setscrew on the handle's side.
3. Pull the handle or knob off exposing the valve assembly.

6. Push in the gear wheel to the new position and press the circular plate on top of it locking the new setting.
7. Slide the knob or handle onto the valve stem and secure it with the screwdriver or Allen wrench, depending on the model.
