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 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.

3. Water Temperature Adjustment

CAUTION: Risk of personal injury. The water temperature
should never be set above 120° F (49° C).

NOTE: Do not remove the O-ring and collar at this time. Removing
the O-ring and collar will change the factory setting for the
maximum water temperature.

Turn the valve clockwise to the full open position and let the hot
water run for several minutes. Position a thermometer in the
water stream and check the temperature.

For minor water temperature changes, adjust the setscrew, and
recheck the water temperature.

For major water temperature changes, remove the O-ring and
collar from the valve stem. Slowly rotate the valve stem until the
desired maximum water temperature is reached.

Reinstall the collar on the valve stem with the setscrew against
the side of the tab.

Reinstall the O-ring, rotate the valve stem counterclockwise to
shut the water off.

Recheck the water temperature.
Complete the information on the valve label (if supplied).
