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.
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 ANSI A112.18.1 and ASSE 1016.
If you do not understand any of the installation or temperature
adjustment instructions in this document, in the United States please
contact our Customer Service Department at 1-800-4-KOHLER.
Outside the U.S., please contact your distributor.
IMPORTANT NOTICE TO INSTALLERS! Please fill in the blanks in
the information box in the Homeowners Guide and on the valve label.
Retain the Homeowners Guide for future reference.

Tools and Materials
Thank You For Choosing Kohler Company
We appreciate your commitment to Kohler quality. Please take a few

hesitate to contact us. Our phone numbers and website are listed on
the back cover. Thanks again for choosing Kohler Company.
Before You Begin
DANGER: 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.
CAUTION: Risk of scalding. This device has been calibrated at
the factory to ensure a safe maximum water temperature. Any
variance in settings or water inlet conditions from those used
during factory calibration may raise the discharge temperature
above the safe limit, and may present a scalding hazard.
Responsibility for installation and adjustment of this device in
accordance with these instructions lies with the installer.
Shut off the main water supply.
Observe all local plumbing and building codes.
The valve is calibrated to 104° F (40° C) at the first stop position,
and the maximum temperature limit stop is positioned so the
outlet water temperature does not exceed 120° F (49° C).

Before You Begin (cont.)
Factory calibrated inlet conditions are: Hot and cold water
pressure = 43-1/2 psi (3 kg/cm) Hot water supply temperature
= 149° F (65° C) Cold water supply temperature = 59° F (15° C).
If inlet conditions differ from those used during factory
calibration, it may be necessary to re-calibrate the valve after
installation. The installer must check the mixed flow
temperature after installation, and adjust the valve as needed
according to the instructions.
Kohler Co. reserves the right to make revisions in the design of
products without notice, as specified in the price book.

1. Water Temperature Adjustment
CAUTION: Risk of personal injury. The water temperature
should never be set above 120° F (49° C).
NOTE: This valve has been calibrated at the factory to provide 104°
F (40° C) at the mixing valve’s first stop position, and 120° F (49° C)
at the maximum temperature limit stop. Check the ″Before You
Begin″section of this manual for detailed factory conditions and
compare them to your inlet water conditions. If they differ
dramatically, then you may need to re-calibrate the valve.
NOTE: Do not turn the mixing valve stem at this time. Turning it
will change the factory calibration setting.
Turn the water on and let the water run for several minutes.
Position a thermometer in the water stream and check the
maximum temperature.
If the existing water supply conditions match the factory
conditions, the water temperature should be close to 104° F (40°
C). If the water temperature differs, then remove and discard the
plaster guard if it is still attached.
Slowly rotate the thermostatic mixing valve stem until the water
temperature is a constant 104° F (40° C). The white mark on the
limit stop should be in line with the black mark on the mixing
valve body. If necessary, carefully pry the limit stop off the valve
cartridge with a thin blade, and re-install it so the white mark
faces upward as required. The limit stop must be correctly
positioned to ensure trim fit.

Water Temperature Adjustment (cont.)
Do not turn the thermostatic mixing valve stem after you adjust
the temperature setting until you have installed the mixing
handle trim.

2. Install the Trim
Installing Mixing Valve Trim (K-400 and K-401 Models)
Remove and discard the plaster guard if it is still in place.
Thread the collar(s) to the valve and hand tighten.
Verify that each trim seal is correctly installed in an escutcheon
hole. The seal(s) should be installed so the flat side faces outward
and the tapered side faces inward.
Remove the backing from the adhesive gasket material. Starting
at the escutcheon drain opening, carefully apply the gasket
material around the back edge surface of the escutcheon.
Once applied, carefully trim away any excess gasket material so
the escutcheon drain opening is not blocked.
Carefully slip the escutcheon over the collar(s) and against the
finished wall. Position the escutcheon so the ″Kohler″logo is at
the top.
Secure the escutcheon to the valve with two screws.

Install the Trim (cont.)
NOTE: Proceed to the ″Complete Trim Installation″section for the
K-400 mixing valve.
Installing Volume Control Trim (K-401 Model Only)
Rotate the volume control valve stem fully counterclockwise.
Press the volume control knob onto the volume control valve
stem so the indicator graphic for off (smallest line) is to the top
(toward the top escutcheon detent, as shown in the illustration).
Secure the volume control knob to the valve stem with the screw.
For Round Handle: Carefully install the thin O-ring into the first
groove in the volume control knob. Fit the grip ring into the
second groove in the volume control knob.
For Lever Handle: Install the O-ring into the groove in the
volume control knob.
For Both Handles: Press the cap into the volume control knob so
the cap detent is in line with the indicator graphic for high on the
volume control knob (as shown in the illustration). If needed,
apply a small amount of lubricant to the inside wall of the cap to
aid in assembly; a capsule of lubricant is included in the
hardware kit.

3. Complete Trim Installation – All Models
NOTE: Units sold internationally will have Celsius temperature
numbers of 32, 40 and 49 on the mixing valve.
Press the mixing valve knob onto the mixing valve stem so the
knob button and ″104″or ″40″mark face upward (toward the
escutcheon detent, as shown in the illustration).
Verify that the knob does not rotate counterclockwise. Do not
press the knob button while trying to rotate the knob.
Turn on the water for a few minutes. Check the water
temperature with a thermometer to confirm that it is at 104° F
(40° C).
If the water temperature matches the marked setting, then rotate
the knob fully counterclockwise so the ″120″or ″49″mark faces
upward.
Let the water run briefly and check the water temperature with
the thermometer to confirm that it is at 120° F (49° C).
If the water temperature matches the marked setting, then rotate
the knob clockwise so the ″104″or ″40″mark faces upward again.

Complete Trim Installation – All Models (cont.)
Let the water run briefly and check the water temperature with
the thermometer again to confirm that it returns to 104° F (40° C).
Once confirmed, turn off the water.
NOTE: If any of the water temperatures do not match the knob
mark settings, repeat the mixing valve calibration steps in the
″Water Temperature Adjustment″section.
Press the cap onto the valve so the cap detent is in line with knob
button (as shown in the illustration). If needed, apply a small
amount of lubricant to the inside wall of the cap to aid in
assembly; a capsule of lubricant is included in the hardware kit.
