Adjusting the Rotational Limit Stop
The rst position allows the LEAST amount
of hot water to mix with the cold water in the
system. In the rst 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 great-
est risk of scald injury if someone accidentally
turns the valve handle all the way to the hot
side while showering or lling a tub.
• 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 10, step 5D) 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 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.
• 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.

WARNING: 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.
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.
WARNING: Failure to re-install Disc
after setting Rotational Limit Stop could
result in scald injury.
