Adjusting the Rotational Limit Stop (Aug 2014 and after)
B

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 on all the way to hot. As you
move the Rotational Limit Stop counter-clockwise, 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 Rota-
tional Limit Stop in the hottest position (full
counter-clockwise) 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 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 (see page 8, step 4D) and
rotate the handle counter-clockwise 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 white Rotational Limit Stop (1)
outward and rotate. Clockwise will decrease the
outlet temperature, counter-clockwise rotation will
increase the outlet temperature. Temperature change
per tooth (notch) could be 4°-16°F based on inlet
water conditions. Repeat as necessary. When
finished, make sure that the Rotational Limit Stop is
fully retracted into the seated position.
WARNING: Do not take the Rotational Limit Stop
apart.
• MAKE SURE COLD WATER FLOWS FROM THE
VALVE FIRST. MAKE SURE WATER FLOWING
FROM THE VALVE AT THE HOTTEST FLOW
POSSIBLE DOES NOT EXCEED 120°F OR THE
MAXIMUM ALLOWED BY YOUR LOCAL PLUMB-
ING CODE.
