RE-CALIBRATION PROCEDURE

1.To re-calibrate the valve, it is necessary to gain access to the spindle (located behind the temperature extension near the top of the valve).

2.Turn the temperature extension counter- clockwise until it stops.

3.Loosen and remove the screw in the center of the temperature extension by turning it counterclockwise.

4.Carefully remove the temperature extension without turning it or the spindle behind it. You have now accessed the spindle.

5.To increase the temperature, rotate the spindle counter-clockwise one or two spline(s) past the mark on the retaining nut. To decrease the temperature, rotate the spindle clockwise one or two spline(s) past the mark on the retaining nut.

6.Replace the temperature extension, positioned fully counter-clockwise with the tab as close as possible to the clockwise side of the pin in the retaining nut. This should be done without rotating the spindle. Do not install the screw at this time.

7.Turn the flow handle counter-clockwise to start the flow of water.

8.After the water temperature has stabilized, check the temperature. This will be the new maximum temperature. If the temperature is not suitable, remove the temperature extension as described above and repeat this procedure to further adjust the water temperature.

9.When the maximum temperature is acceptable, re-install the screw in the temperature extension and tighten.

10.Refer to “Attach Temperature Knob” instructions on how to re-attach the temperature knob.
