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.

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.

NOTE: Ensure that the holes are not oversized. The spout and
valve bodies require adequate base material strength and maximum
contact area with the deck.

Drill a 1-1/8″ (29 mm) spout hole. Do not exceed this hole size.
Drill two 1-1/2″ (38 mm) valve body holes, one on either side of

the spout hole. Do not exceed this hole size.
