If the water temperature is above 120°F, remove the temperature control knob (1) and rotate the limit stop (2) clockwise one tooth for every 4°F - 6°F (approximate)
change in temperature. If water temperature is cooler than desired, rotate the limit stop counterclockwise.
IMPORTANT: The first position of the Rotational Limit Stop (the Limiter) is that position that restricts the rotation of the stem the most and is at the maximum clockwise setting. According to industry standards, the maximum allowable temperature of the water exiting from the valve is 120o F. This temperature may vary in your local area. The Rotational Limit Stop may need to be readjusted if the inlet water temperature changes. For instance, during the winter, the cold water temperature is colder than it is during the summer which could result in varying outlet temperatures. Typical temperature for a comfortable bath or shower is between
