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.

Tools and Materials
Before You Begin
CAUTION: Risk of product damage to the K-306-KS valve
assembly. When using this valve in a fiberglass or acrylic
installation, use the Thin Wall Installation Kit (88526).
Observe all local plumbing and building codes.
The finished wall or bath/shower unit must be installed prior to
installing this trim.
Before installing the trim, determine if the maximum water
temperature is acceptable to the user. If temperature adjustment is
needed, refer to the ″Optional Temperature Limiting Adjustment″
section of this guide.
The valve shuts off by water pressure. Do not force the handle in
any direction. To turn the valve off, gently turn it to the ″OFF″
position.
Shut off the main water supply.
Kohler Co. reserves the right to make revisions in the design of
products without notice, as specified in the Price Book.

1. Install the Spout
Remove the temporary nipple.
Apply thread sealant and install a 1/2″nipple so it extends
1-1/4″(3.2 cm) beyond the finished wall.
Apply thread sealant to the nipple and thread the spout onto the
nipple.
Carefully tighten with a clean strap wrench.

2. Install the Showerhead
CAUTION: Risk of product damage. To avoid clogging the
showerhead spray outlets, use thread sealant tape on the
shower arm threads. Do not use thread sealant compound
(pipe dope).
Remove the temporary nipple from the shower elbow.
Apply thread sealant to the shower elbow, then install a 1/2″
NPT pipe nipple to the shower elbow. The nipple must extend
1-1/4″(3.2 cm) beyond the finished wall.
Turn the main water supply on.
Run hot and cold water through the shower arm to flush out dirt
and debris.
IMPORTANT! If a gasket is NOT installed on the escutcheon of
the shower arm: Apply a bead of plumbers putty or other sealant to
the back of the shower arm. Refer to the putty or sealant
manufacturer’s instructions for proper application. This will ensure a
watertight seal.
Apply thread sealant tape to the pipe nipple and thread the
shower arm onto the pipe nipple.
Carefully tighten the shower arm to the pipe nipple with a clean
strap wrench.
Remove all excess putty around the escutcheon.

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

5. Install the Faceplate and Handle
CAUTION: Risk of product damage to the K-306-KS valve
assembly. When using this valve in a fiberglass or acrylic
installation, use the Thin Wall Installation Kit (88526).
For installation over a tiled wall, apply a bead of silicone sealant
around the back edges of the faceplate.
Break off the tab at the lower right on the backing plate. Fit the
backing plate over the valve so the large hole is on the bottom
and secure with two screws. Do not overtighten.
Rotate the valve stem fully counterclockwise.
Position the faceplate over the backing plate and thread the collar
into the backing plate. Do not cross thread.
Insert the sleeve into the notches of the collar and hand tighten. If
the collar does not thread into the backing plate, thread the
backing plate screws 1/2 turn back.
Insert the stem extension through the sleeve and collar with the
flat sections of the stem extension facing up.
Attach the stem extension to the valve stem with the flat head
screw.
Insert the handle screw through the handle stem.
Place the handle over the handle stem.
Securely tighten the handle screw to the handle.
Attach the handle stem with the attached handle to the stem
extension.

INSTRUCTIONS IMPORTANTES
À LIRE ET À LAISSER AU CLIENT
AVERTISSEMENT : Risque de brûlures ou autres 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 chauffe-eau, changeront la
température maximale de l’eau fournie par le régulateur et
pourront présenter un danger de brûlures.
•La valve à pression réguléene 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.
•Les valves à pression équilibrée peuvent ne pas assurer une
protection contre les brûlures en cas de défaillance d’autres
dispositifs de limitation de température installés ailleurs sur le
réseau de plomberie.
L’installateur est responsable de l’installation de la valve et du
réglage de la température maximale de cette valve selon les
instructions.
Cette valve satisfait ou excède les exigences des normes ANSI
A112.18.1M et ASSE 1016.
