WARNING: This system/device must be set by the installer to ensure safe, maximum temperature. Any change in
the setting may raise the discharge temperature above the limit considered safe and may lead to scalds.
CAUTION: As the installer of this valve, it is your responsibility to properly install and adjust this valve per the
instructions given. This valve does not automatically adjust for inlet temperature changes, therefore, it is necessary
to adjust the Rotational Limit Stop at the time of installation. You must inform the owner/user of this requirement by
following the instructions below. After installation and adjustment, you must write in the temperature and the date
you adjusted the Rotational Limit Stop on the warning label provided and apply or attach it to the hot water heater.
Be sure this instruction sheet is delivered to the owner/user.
WARNING: This pressure balanced bath valve is designed to minimize the effects of outlet water temperature
changes due to inlet pressure changes, commonly caused by dishwashers, washing machines, toilets and the like.
It may not provide protection from scalding when there is a failure of other temperature controlling devices elsewhere
in the plumbing system if the Rotational Limit Stop is not properly set, or if the hot water temperature is changed after
the Rotational Limit Stop is set, or if the water inlet temperature changes due to seasonal changes.
INSTALLER: LEAVE THIS INSTRUCTION MANUAL FOR OWNER'S/USER'S REFERENCE

8. Slide bonnet nut (1) over the cartridge and thread
onto the body. Hand tighten securely.
WARNING:Insomeinstances,settingtheRotational
Limit Stop in the hottest position (full counterclock-
wise) 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.
Adjustrotationallimitstop. Afterwaterhasrunasufficient
length of time so that cold water is as cold as it will get,
and hot water is as hot as it will get, place handle back
on stem and rotate handle counter clockwise to the hot-
test position. Place a thermometer in a plastic tumbler,
and hold the tumbler in the water stream. Record the
temperature reading and note or mark the position of
the Rotational Limit Stop on the mating part. If the water
temperature is above 120°F the Rotational Limit Stop
must be rotated clockwise to reduce the temperature
(See illustration).

9. Flush your system prior to installing the shower
head. Place handle on valve stem and turn handle to
full mix position. Turn ON water supplies, check for
leaks and let lines flush for one minute without moving
faucet handle. Divert water to shower head and flush
for 30 seconds. This will remove any debris from lines
which can damage internal parts of the faucet and
create leaks. After flushing, shut OFF water at faucet.
Remove handle and attach escutcheon. Attach shower
head.

10. 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 ac-
cidentally 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.AsyoumovetheRotationalLimitStopcounterclock-
wise, 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 filling a tub.

HELPFUL HINTS:
1. Before removing cartridge assembly for any maintenance, be sure to note the position of the stop on the cap.
The cartridge assembly must always be put back in the same position. For normal installations, the stop on the cap
will face the left. To be safe, after you have finished the installation turn ON valve to make sure cold water flow
first.
2. To remove cartridge from body, shut OFF water supplies and remove handle, trim sleeve and bonnet. Place
handle on stem and rotate clockwise while lifting cartridge out of body.
3. To remove seats and springs, remove cartridge (see above). Separate cap assembly from the housing assem-
bly by rotating the cap counter clockwise 90 degrees. Separate cap and housing assemblies. Remove seats and
springs. Place new seats and spring. Place the largest diameter of the spring into the seat pocket first and then
press the tapered end of the seal over the spring. Reassemble cartridge and replace in body following instructions
given in Step 1 above.
4. If the water in your area has lime, rust, sand or other contaminants in it, your pressure balanced valve will require
periodic inspection. The frequency of the inspection will depend on the amount of contaminants in the water. To
inspect cartridge, remove it and follow Step 1. Turn the valve to the full mix position and shake the cartridge rigor-
ously. If there is a rattling sound, the unit is functional and can be reinstalled following instructions given in Step 1
as listed. If there is no rattle, replace housing assembly.
No adjustment to the Optica shower mixer Rotational Limit Stop should be made except by a trained installer.

Setting of limiter
The first position of the Rotational Limit Stop (the Limiter) is that position that restricts the rotation of the stem the
most and is at the maximum counterclockwise setting. According to industry standards, the maximum allowable
temperature of the water exiting from the valve is 120°F. This temperature may vary in your local area. The Rota-
tional Limit Stop may need to be readjusted if the inlet water temperature changes. For instance, during the winter,
the cold water temperature is colder than it is during the summer which could result in varying outlet temperatures.
Typical temperature for a comfortable bath or shower is between 90°-110°F.
