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.

NOTICE TO HOMEOWNERS! This device has been preset by
_______________________ of _______________________________ to
ensure a safe maximum temperature. Any change in the setting may

Before You Begin (cont.)
Flush all piping thoroughly before installing this Rite-Temp valve.
Do not use plastic pipe between the Rite-Temp valve and the
spout. Use 1/2″ nominal copper tube or 1/2″ iron pipe.
Do not connect a deck-mount spout, diverter, or hand shower to
the spout outlet unless you cap the shower outlet on the valve.
Install a pipe or tube in a straight drop of 7” (17.8 cm) to 18″
(45.7 cm) with only one elbow between the valve and the
wall-mounted spout. Other types of installation may cause
unsatisfactory shower performance.
