Operating Guide

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 greatest 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
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
nished, make sure that the Rotational Limit
Stop is fully retracted into the seated position.
• 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, 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 lling 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: Do not take the Rotational
Limit Stop apart.
