Tools and Materials
Before You Begin
WARNING: Risk of personal injury. Do not install the bath
faucet in an area where it may inadvertently be used for
support by the bather.
CAUTION: Risk of property damage. Select a cutting tool
appropriate for the deck/rim surface type. Refer to the
surface manufacturer’s instructions for the proper cutting
procedures.
Observe all local plumbing and building codes.
Shut off the water supply.
Protect the surface of the bath deck/rim during installation.
Kohler Co. recommends installing a Sioux Chief 652-AD vacuum
breaker arrestor (or equivalent) close to the outlet of the remote
valve. This will reduce cavitation and water hammer when the
valve or diverter is activated. Visit Sioux Chief’s website at
www.siouxchief.com for technical and installation information.

Roughing-In
1. Prepare the Site
NOTE: To simplify future servicing, install an access panel to reach
the plumbing.
NOTICE: The remote valve may be installed anywhere on the deck.
To allow adequate clearance for handle rotation, provide a minimum
distance of 5-3/4″(146 mm) from the center of the spout to the
center of the valve.
Determine the mounting hole locations for the spout diverter and
remote valve. Refer to the roughing-in dimensions illustrated for
proper placement and diameters.
For a finished bath deck/rim less than 5/8″(16 mm) thick: Install
wood reinforcement to the underside of the deck/rim. The
combined thickness of the reinforcing material and the deck/rim
must not exceed 3″(76 mm).
CAUTION: Risk of property damage. Select a cutting tool
appropriate for the deck/rim surface type. Refer to the
surface manufacturer’s instructions for proper cutting
procedures.
