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
Before You Begin
IMPORTANT! This instruction provides installation information for
two faucet models. Be sure to follow the steps that apply to your
installation.
Please read all instructions before you begin.
Observe all local plumbing and building codes.
Shut off the main water supply.
The K-1099 uses two valves, one for the bath fill, and another for
the shower. Pay special attention to this feature when planning
your site preparation.
Avoid excessive heat if you solder connections to prevent damage
to the fitting.
Flush all piping thoroughly before installing the valve(s).
Do not force the handle(s) in any direction. To turn the valve off,
gently turn it to the ″Off″position.
For the K-1099, do not use any plastic pipe between the valve and
the spout.

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.

4. Install the Yoke - Ceiling Installations
IMPORTANT! Perform these steps for ceiling installations only.
The faucet fitting is factory assembled specifically for hot and
cold water supplies from the floor.
If installing the faucet for ceiling supplies, turn the yoke over so
the supplies connect from the top.
Remove the aspirator with a 3/8” hex wrench.
For the K-1098, reinstall the aspirator at the top of the yoke. Do
not overtighten. For the K-1099, discard the aspirator.
Reversing the yoke for ceiling supplies reverses the direction the
lever handles close.
For proper operation, reverse the ceramic valves.
Open the valve before removing it.
Tighten the valves securely.
If you are installing K-1099, proceed to the next section.

AVERTISSEMENT : Risque de brûlures ou de blessures graves.
•Avant de commencer l’installation, l’installateur doit régler la
température maximale de l’eau de cette valve pour réduire au
minimum les risques de brûlures, ceci conformément à la norme
ASTM F 444.
•Ne pas installer un dispositif d’arrêt sur les sorties de cette valve.
L’installation d’un tel dispositif peut créer une condition de débit
croisé au régulateur et modifier la température de l’eau.
•Les facteurs qui changent la température de l’eau fournie à cette
valve, tels que les changements de température d’eau saisonniers,
et le remplacement ou l’entretien du chauffeau, changeront la
température maximale de l’eau fournie par le régulateur et
pourront présenter un danger de brûlures.
•La valve à pression équilibréene compensera pas les changements
de température d’alimentation d’eau; ajuster la température
maximale de cette valve à pression équilibrée si de tels
changements se produisent.
