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
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 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 disc back
to a position where it is possible to 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. 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.
