Tools and Materials
Thank You For Choosing Kohler Company
We appreciate your commitment to Kohler quality. Please take a few minutes
to review this manual before you start installation. If you encounter any
installation or performance problems, please don’t hesitate to contact us. Our
phone numbers and web site are listed on the back cover. Thanks again for
choosing Kohler Company.
Before You Begin
Please read all instructions before you begin.
Observe all local plumbing and building codes.
Before installation, unpack the new faucet and inspect it for damage. Return
the faucet to the carton until you are ready to install.
Leave the protective sleeve on the spout supply tube until the spout is
installed. The spout has an O-ring sealing surface which may be damaged if
unprotected.
Provide an access panel to the valves from under the deck.
Installer-supplied copper tubing is to be 5/8” O.D. (1/2” nominal).
Install water hammer arrestors in the supply lines near the valves.
These instructions cover two methods of installation; installation on finished
deck or rim, and installation on rough (unfinished) deck. Follow the sections
that pertain to your particular installation.
Instructions are given for installations with 8” (20.3cm) centers. For wider
installations, adjust all roughing-in dimensions and copper tubing lengths
accordingly.
Shut off the main water supply.
Kohler Co. reserves the right to make revisions in the design of faucets
without notice, as specified in the Price Book.

1. Prepare the Site
Install or relocate the water supplies as needed.
Protect the surfaces of the bath/deck during installation.
The diameter of the spout hole in the deck is 1” (2.5cm). The diameter of
the valve hole in the deck is 1–1/2” (3.8cm). Ensure that holes drilled into
the deck are not oversized. The spout and valves require adequate base
material strength and maximum contact area with the deck.
Plaster guard diameters are approximately 1–5/8” (4.1cm) for the valves
and 13/16” (2.1cm) for the spout.
NOTE: Reinforcing material may be required if the deck or rim is thin.
Install before proceeding.
NOTE: For installations to be covered with tile, the tile thickness must not
exceed 1–1/4” (3.2cm).

2. Installation on Finished Deck or Rim
NOTE: For installation on a rough (unfinished) deck, proceed to Installation
on Rough (Unfinished) Deck.
Use 1/2” nominal, 5/8” O.D. copper tubing. Cut two pieces of tubing to a
length of 2–7/8” (7.3cm). Cut one piece of tubing to a length of 2–3/8”
(6cm) for the spout supply.
IMPORTANT! Leave the protective sleeve on the spout supply tube until
the spout is installed to protect the O-ring sealing surface.
Install Spout Supply Tube
Slide a brass washer from the bottom of the spout supply tube over the
threads until the washer reaches the supply tube shoulder.
Insert the spout supply tube through the mounting hole from the top of the
deck/rim. Ensure that the flat portion of the washer faces forward. The
supply tube will be suspended by the washer.
Slide a brass washer onto the spout supply tube from the bottom and
thread the mounting nut. Tighten the nut.
NOTE: Do not use the supplied wood screws for installation on finished
deck or rim.
Install Valve Bodies
Thread one mounting nut, flange side up, onto each valve body.
NOTE: Rims less than 1/4” (6mm) thick require two rubber washers in the
following step; other installations require one rubber washer.

Installation on Finished Deck or Rim (cont.)
Slide one fiber washer, followed by one or two rubber washers, onto each
valve body.
Insert the 2–7/8” (7.3cm) long copper tubes between the valve bodies and
the 1/2” tee. Insert the 2–3/8” (6cm) long copper tube into the top of the
tee.
Do not solder the connections at this time.
NOTE: The valve body marked “Cold” must be on the right side when you
are facing the front of the faucet.
Insert the valve bodies through the mounting holes from the bottom of the
deck/rim. Match the copper tube from the tee with the spout supply tube.
Hold in place.
Place a collar with the flange side up, onto each valve body. Thread the
collar down to at least 1” (2.5cm) from the top thread on the valve body.
Tighten the mounting nuts on each valve body from underneath the
deck/rim.
Solder the copper tubes to the valve bodies, tee and spout supply tube.
Solder the hot and cold water tubes to the valve body inlets. Ensure that the
cold supply is on the right side.
Proceed to Check Operation of Valves.

3. Installation on Rough (Unfinished) Deck
Use 1/2” nominal, 5/8” O.D. copper tubing. Cut two pieces of tubing to a
length of 2–7/8” (7.3cm). Cut one piece of tubing to a length of 2–3/8”
(6cm) for the spout supply.
IMPORTANT! Leave the protective sleeve on the spout supply tube until
the spout is installed to protect the O-ring sealing surface.
Install Spout Supply Tube
Slide a brass washer from the bottom of the spout supply tube over the
threads until the washer reaches the supply tube shoulder. Ensure that the
countersunk holes in the washer are facing upward.
Insert the spout supply tube through the mounting hole from the top of the
deck. Ensure that the flat portion of the washer faces forward. The supply
tube will be suspended by the washer.
Slide a brass washer onto the spout supply tube from the bottom and
thread the mounting nut. Tighten the nut.
Secure the brass washer to the deck using the two supplied wood screws.
Install Valve Bodies
Thread one mounting nut, flange side up, followed by one fiber washer and
one rubber washer onto each valve body.
Insert the 2–7/8” (7.3cm) long copper tubes between the valve bodies and
the 1/2” tee.
Do not solder the connections at this time.

4. Complete Installation on Rough Deck
Set Valve Body Height
NOTE: Use one of the following two formulas to calculate the valve body
clearance required for the finish material at your site.
For tile that is less than 1” (2.5cm) thick, add 1–1/4” (3.2cm) to the tile
thickness. Example: Tile thickness is 3/4” + 1–1/4” = 2” (5cm) of clearance
required.
For tile that is between 1” (2.5cm) and 1–1/4” (3.2cm) thick, add only 1”
(2.5cm) to the tile thickness. Example: Tile thickness is 1–1/4” + 1” = 2–1/4”
(5.7cm).
Adjust the threaded collar until the dimension from the top of the valve
threads to the top of the rough deck equals the clearance requirement
needed. Make a note of this dimension. You will use it again after
connecting the supply tube.
Connect Supply Tube
Measure the distance from the bottom of the spout supply tube to the top of
the tee.
Add 1” (2.5cm) to this measurement and cut a piece of copper tubing to fit
into the supply tube and tee port.
Fully loosen the threaded collars but do not remove them.
Pivot the valve bodies enough to remove the tee and two pieces of tubing.
If the valve body holes are smaller than recommended, it may be necessary
to remove the entire valve body assembly.
Install the tubing into the tee. Match the copper tube from the tee with the
spout supply tube.

Ensure that the cold supply is on the right side.
Solder the hot and cold water supply tubes to the valve body inlets.

5. Check Operation of Valves
Thread a 1/4” pipe plug into the top of the spout supply tube.
Ensure that the valves are closed (cold — fully counterclockwise; hot —
fully clockwise).
Turn on the main water supply and check the complete installation for leaks
with the valves closed and open. Repair leaks as needed.
Close both valves and turn off the main water supply.
WARNING: Risk of personal injury. Lines will be pressurized. Do not
lean over pipe plug as you remove it.
Wrap a towel around the pipe plug to prevent water spray. Water will
purge from the supply tube when you remove the plug.
Carefully loosen the pipe plug to remove pressure.
Thread the pipe plug back into the spout supply tube. Leave the pipe plug
installed until the spout and handles are installed.
Install the cardboard plaster guards over both valves and the spout supply
tube. Leave in place until the spout and handles are installed.
6. Install Tile (If Applicable)
Verify that there will be a 1–1/4” (3.2cm) distance from the top of the sleeve
to the top of the tile. If there is not, correct the valve clearance as described
earlier.
Install tile up to the plaster guards on the valves and the spout supply tube.
