IMPORTANT INSTRUCTIONS
READ AND SAVE FOR THE
CONSUMER
WARNING: Risk of scalding or other severe injury.
•Before completing installation, the installer must set the
maximum water temperature setting of this valve to minimize the
risks associated with scalding hazards according to ASTM F 444.
•Do not install a shut-off device on either outlet of this valve. The
installation of any such device may create a cross-flow condition
at the valve and affect the water temperature.
•Factors that change the temperature of the water supplied to the
valve, such as seasonal water temperature changes, and water
heater replacement or servicing, will change the maximum water
temperature supplied by the valve and may create a scalding
hazard. The pressure-balanced valve will not compensate for
changes in the water supply temperature; adjust the maximum
water temperature setting of this pressure-balanced valve when
such changes occur.
•Pressure-balanced valves may not provide protection against
scalding if there is a failure of other temperature-limiting devices
elsewhere in the plumbing system.
NOTICE: Only apply silicone based lubricants to these valves. Do
not use petroleum based lubricants. Petroleum based lubricants will
harm the O-rings, seals, and plastic components.
The installer is responsible for installing the valve and adjusting the
maximum water temperature of this pressure-balanced valve
according to instructions.
This valve meets or exceeds ASME A112.18.1/CSA B125.1 and ASSE
1016/ASME A112.18.1016/CSA B125.16.
If you do not understand any of the installation or temperature
adjustment instructions in this document, in the United States please
contact our Customer Care Center at 1-800-4KOHLER. Outside the
U.S., please contact your distributor.
IMPORTANT NOTICE TO INSTALLERS! Please fill in the blanks in
the adjacent box and on the valve label. Then insert these instructions
into the plastic bag included with the valve package, and attach the
plastic bag to the valve handle for the homeowner’s reference.

Before You Begin (cont.)
NOTE: For service parts information, visit your product page at
www.kohler.com/serviceparts.
Observe all local plumbing and building codes.
This valve requires a minimum operating pressure of 15 psi (103.4
kPa).
The valve shuts off by water pressure. Do not force the handle in
any direction. To turn the valve off, gently turn it to the ″Off″
position.
Flush all pipes thoroughly after installing the valve body.
If inlet conditions differ from those used during factory
calibration, it may be necessary to re-calibrate the valve after
installation.
Do not use plastic piping between the valve and the spout.
Kohler Co. recommends the use of 3/4″copper tube. Iron pipe is
not recommended.
This valve does not have an integral aspirator. For installations
that use a bath diverter spout, you must install a twin ell (K-9663)
with integral aspirator between the valve and the bath spout. If
these thermostatic mixing valves are installed without an
aspirator it will cause water to flow from the shower and bath
spout at the same time.
1. Prepare the Site
IMPORTANT! If the bath has been installed, cover it to prevent
damage to the bath surface.
Rough Plumbing
Shut off the water supply.
Install or relocate the supplies as necessary.
