Installation Guide

IMPORTANT:
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 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 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.
WARNING: Do not take the Rotational Limit
Stop apart.
• 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.
