WARNING:
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 than 120°F).
• The Rotational Limit Stop may need to be re-
adjusted 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.
NOTICE:
Do not take the Rotational Limit Stop
apart.

WARNING
: TO AVOID THE RISK OF
PERSONAL 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.
