ADJUSTING THE ROTATIONAL LIMIT STOP:
IMPORTANT:
The Rotational Limit Stop is used to limit the amount of hot water available such that, if set properly, the user will not be scalded if the
handle accidentally is rotated all the way to “hot” when a person is showering or filling a tub. The first position allows the
LEAST
amount of hot water to
mix with the cold water in the system. In the first position the water will be the coldest possible when the handle is turned all the way to hot. As you move
the Rotational Limit Stop counterclockwise, you progressively add more and more hot water in the mix. The last position to the left will result in the greatest
amount of hot water to the mix, and the greatest risk of scald injury if someone accidentally turns the valve handle all the way to the hot side
while showering or filling a tub.
WARNING: In some instances, setting the Rotational Limit Stop in the hottest position (full counterclockwise) could result in scald injury. It is
necessary to adjust the Rotational Limit Stop so that the water coming out of the valve will not scald the user when the handle of the valve is
rotated to the hot side.
• According to the majority of industry standards, the maximum allowable temperature of the water exiting the valve is 120°F (Your local plumbing codes
may require a water temperature less than 120°F).
• The Rotational Limit Stop may need to be readjusted seasonally if the inlet water temperature changes. For example, during the winter, the cold water
temperature is colder than it is during the summer which could result in varying outlet temperatures. A water temperature for a comfortable bath or
shower is typically between 90°F - 110°F.
• Run the water so that the cold water is as cold as it will get and hot water is as hot as it will get. Place the handle on the stem and rotate the handle
counterclockwise until the handle stops.
• Place a thermometer in a plastic tumbler and hold in the water stream. If the water temperature is above 120°F, the Rotational Limit Stop must be
repositioned clockwise to decrease valve outlet water temperature to be less than 120°F or to meet the requirements of your local plumbing codes.
• To adjust the temperature of the water coming out of the valve, pull the disc back to a position where it is possible to remove the Rotational Limit Stop
and readjust the teeth engagement position to the desired temperature. Clockwise will decrease the outlet temperature, counterclockwise will increase
the outlet temperature. Temperature change per tooth (notch) could be 4° - 16°F based on inlet water conditions. Repeat as necessary. Push disc until
fully seated.
WARNING: Failure to re-install Disc after setting Rotational Limit Stop could result in scald injury.
•
MAKE SURE COLD WATER FLOWS FROM THE VALVE FIRST.
MAKE SURE WATER FLOWING FROM THE VALVE AT THE HOT TEST FLOW
POSSIBLE DOES NOT EXCEED 120°F OR THE MAXIMUM ALLOWED BY YOUR LOCAL PLUMBING CODE.
