Rotational Limit Stop / Butée de rotation / Tope de rotación
•
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 filling a tub.
With the Rotational Limit Stop in the first position the GREATEST amount of hot water is in the mix, and the greatest risk of scald injury if someone
•
accidentally turns the valve handle all the way to the hot side while filling a tub.
•
With the Rotational Limit Stop in the last position the LEAST amount of hot water is in the mix.
•
As you move the Rotational Limit Stop counterclockwise, you progressively reduce the hot water in the mix.
•
MAKE SURE COLD WATER FLOWS FROM THE VALVE FIRST. MAKE SURE WATER FLOWING FROM THE VALVE AT THE HOTTEST FLOW
POSSIBLE DOES NOT EXCEED 49ºC (120°F) OR THE MAXIMUM ALLOWED BY YOUR LOCAL PLUMBING CODE.
•
In some instances, setting the Rotational Limit Stop in the hottest position (First Position) 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 49ºC (120°F) (Your local plumbing
codes may require a water temperature less than 49ºC (120°F)).
•
The Rotational Limit Stop may need to be re-adjusted 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 32° - 43°C (90°F - 110°F).
Setting Rotational Limit Stop
1. Run the water with the handle (1) in the "Cold" position until it is as cold as it will
get and then repeat in the "Hot" position until it is as hot as it can get.
2. Place a thermometer (5) in a plastic tumbler and hold in the water stream.
If the water temperature is above 49ºC (120°F), the Rotational Limit
Stop must be repositioned counterclockwise to decrease valve outlet water
temperature to be less than 49ºC (120°F) or to meet the requirements of your
local plumbing codes.
3. Loosen the handle set screw (2) and remove the handle (1) and adjust the
temperature of the water coming out of the valve:
i. Pull the Rotational Limit Stop (3) off of the bonnet nut (4) and re-adjust the
teeth engagement position between the "First" and "Last" positions to the
desired temperature.
•
Clockwise towards the "First" position will increase the outlet
temperature.
•
Counterclockwise towards the "Last" position will decrease the
outlet temperature,
Temperature change per tooth (notch) could be -15° - -9°C(4° - 16°F)
based on inlet water conditions.
ii. Push Rotational Limit Stop (3) onto the bonnet nut (4) until fully seated.
4. Re-install handle (1) and tighten set screw (2).
5. Fully open the handle to the "Hot" position and repeat Step 2.
6. Repeat Steps 3 to 5 as necessary.
