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 han-
dle 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 Rotation-
al 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 tempera-
ture less than 120°F).
• The Rotational Limit Stop may need to be re-
adjusted seasonally if the inlet water tempera-
ture changes. For example, during the winter,
the cold water temperature is colder than it is
during the summer which could result in vary-
ing 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 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 require-
ments 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 tem-
perature. 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 HOTTEST FLOW POSSIBLE
DOES NOT EXCEED 120°F OR THE
MAXIMUM ALLOWED BY YOUR LOCAL
PLUMBING CODE.
