Before You Begin
These instructions detail both finished deck or rim, and rough deck installations. Follow only the instructions for your particular installation.
Observe all local plumbing and building codes.
Supply 1/2″ nominal (5/8″ OD) copper tubing.
Shut off the water supply.
Provide an access panel for servicing the valves.
Instructions are given for installations with 8″ (203 mm) centers. For wider installations, adjust all roughing-in dimensions and copper tube lengths accordingly. If the spout is to be installed more than 24″ (610 mm) from the valves, Kohler Co. recommends installing a Sioux Chief 652-AD vacuum breaker arrestor. Install the vacuum breaker arrestor close to the outlet ports of the valves. For more information, contact Sioux Chief at www.siouxchief.com.
Products purchased separately may change the valve placement and alignment.
Leave the protective guard on the spout supply tube until the spout installation. This is an O-ring sealing surface which may be damaged if left unprotected.
Plaster guard diameters are approximately 1-5/8″ (41 mm) for the valve bodies, and 7/8″ (22 mm) for the spout.
The installed finished deck material must fit closely to the plaster guard diameters.

1. Prepare the Site
IMPORTANT! Verify that the hole locations will not interfere with drain connections or other accessories.
Plan for one spout supply hole and two valve body holes.
Locate the valve body holes 4″ (102 mm) away from the spout supply tube centerline. For wider installations, adjust this measurement accordingly.

Finished-Deck or Rim-Mount Installation
NOTICE: Plywood is required for rim-mount installations to secure the spout supply tube. Follow the bath instructions to correctly cut and position the plywood.
NOTICE: Make sure the plywood will not interfere with other plumbing connections or installation of the bath.
Install 1/2″ (13 mm) exterior grade plywood if the finished deck or rim is less than 1/2″ (13 mm) thick, or if the faucet will be installed directly to the bath rim.
