Adjusting the Rotational Limit Stop
3

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 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 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 stan-
dards, 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 tem-
perature 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 6, step 4D) 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 tempera-
ture 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, 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.
• 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.
