Adjusting the Rotational Limit Stop
B.

IMPORTANT:
The Rotational Limit Stop is used to limit the
amount of hot water available such that, if set
properly, a scald injury is less likely to occur if the
handle accidentally is rotated all the way to "hot"
when a person is showering. 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.
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
than120°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
4C) and rotate the handle coun- terclockwise
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
rotation will decrease the outlet temperature,
counterclockwise 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 PLUMBING CODE.
