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 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 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.

NOTICE TO HOMEOWNERS! This device has been preset by _______________________ of

_______________________________ to ensure a safe maximum temperature. Any change in the setting may

raise the discharge temperature above the limit considered safe, and lead to scalds.
