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

Deep rough-in kit #73444 allows an additional 1/2º (1.3cm) of tile thickness.

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 5/8º O.D. (1/2º nominal).

Install water hammer arrestors in the supply lines near the valves.

These instructions cover two methods of installation; installation on ®nished deck or rim, and installation on rough (un®nished) deck. Follow the sections that pertain to your particular installation.

1. Prepare the Site

Install or relocate the water supplies as needed.

Protect the surfaces of the bath/deck during installation.

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±5/8º (4.1cm) for the valves and 7/8º (2.2cm) 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±1/4º (3.2cm).

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 ®nish material at your site.

For tile that is less than 1º (2.5cm) thick, add 1±1/4º (3.2cm) to the tile thickness. Example: Tile thickness is 3/4º + 1±1/4º = 2º (5cm) of clearance required.

For tile that is between 1º (2.5cm) and 1±1/4º (3.2cm) thick, add only 1º (2.5cm) to the tile thickness. Example: Tile thickness is 1±1/4º + 1º = 2±1/4º (5.7cm).

Adjust the threaded collar until the dimension from the top of the sleeve 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 1º (2.5cm) to this measurement and cut a piece of copper tubing to ®t 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.

Pivot the valve bodies onto the two pieces of copper tubing.

Do not solder at this time.

Reset Valve Body Height

Adjust the threaded collars until the dimension from the top of the sleeve to the top of the rough deck equals the clearance requirement calculated earlier.

Solder Connections

Tighten the mounting nuts on each valve body under the deck.

Solder the copper tubes to the valve bodies, tee and 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.

7. Install Spout

Wrap a towel around the pipe plug and carefully remove it.

Remove the plaster guard from the spout supply tube.

Cut off the spout supply tube 1±1/4º (3.2cm) above the rim, ®nished deck or tile.

Ensure that all burrs are removed from the supply tube.

NOTE: If your installation is on a tile-covered rough deck, slide a brass washer, ¯at side facing forward, onto the supply tube. The brass washer is supplied with the spout. This washer is not needed for rim/®nished deck installations.

Loosen the setscrews in the sleeve. Use a twisting motion to install the sleeve on the spout supply tube until it contacts the washer.

Align the sleeve so the setscrews are not facing directly forward or backward and tighten the setscrews.

CAUTION: Risk of product damage. Use care when installing the spout to prevent damage to the O-ring seal on the sleeve.

Install the spout onto the sleeve and carefully press down until the spout base contacts the ®nished deck surface.

Align the spout and tighten the setscrew. If included, press the plug button into the setscrew hole.

8. Install Handles

NOTE: There are different handle styles available for this product. Only the sculpted handle is shown. Installation of all handle styles is identical.

Remove the plaster guards from the hot and cold valves.

Measure the distance from the top of the valve stem to the ®nished surface.

For a valve stem height between 1±13/16º (4.6cm) and 2±1/8º (5.4cm) use a brass spline adapter and screw. For a valve stem height between 2±1/8º (5.4cm) and 2±5/16º (5.9cm) use a plastic spline adapter.

If the brass spline adapter is required, attach using the screw supplied. The plastic spline adapter slides on with no attachment.

Thread the handle onto the valve body. Ensure that the splines in the handle and spline adapter are engaged.

Position the handle assemblies facing in opposite directions away from the spout.

NOTE: The spline adapter allows ®ne adjustment of the handle alignment. To adjust, unthread the handle and reposition the spline adapter. Rethread the handle and check alignment. Repeat until handle alignment is satisfactory.
