Tools and Materials
Before You Begin
WARNING: Risk of personal injury. This product is a diverter
valve only and should never be used as a shut-off valve. Use as
a shut-off valve will allow cross flow between the hot and cold
water supplies and will create a serious scalding hazard.
Observe all local plumbing and building codes.
Shut off the main water supply.
Provide an access panel for all installations.
Carefully read this entire instruction manual before beginning the
installation; the illustrations do not show all possible
configurations.
Carefully inspect waste and supply tubing for any sign of
damage.
Replace waste or supply tubing if necessary.

Before You Begin (cont.)
You can extend the distance between the between the water
source and the braided hose connection with 1/2″copper piping
below the rim of the bath/whirlpool, but it may not be safe or
practical. A long run of piping will mean a long run of
room-temperature standing water when the handshower is first
activated for use.
CAUTION: Risk of product damage. Excessive heat will damage
the internal plastic components. Follow these steps to avoid
product damage.
IMPORTANT! Do not apply excessive heat while soldering. Direct
the torch flame away from the brass body.
IMPORTANT! Only apply direct heat to the connectors and
extensions.
Do not install spouts with flow restrictors or handheld shower
units on the large (5/8″O.D.) bath outlet.
The Kohler two-way diverter is designed for use with Kohler
non-diverting bath spouts.
Remove all internal components of the diverter valve before
soldering. Kohler Co. recommends soldering supply and optional
outlet connections to avoid potential leakage.
Kohler Co. reserves the right to make revisions in the design of
products without notice, as specified in the Price Book.

1. Diverter Configuration
The small port is for the supplied handshower hose.
The port directly opposite of the handshower port is for an
optional bath spout. Default flow is through this port. If not
utilized, this port will need to be capped.
The remaining two ports are for the hot and cold water. These
connections are interchangeable.
2. Component Layout
Verify the location of the components, and the orientation of all
ports.
Decide in advance on the location and orientation of the diverter.
The location of the shower, and the handshower, as well as the
direction in which the inlets/outlets point, will affect the piping
and connectors needed.
Allow clearance for valve outlets, handles, and handshower
hoses. For use with an optional spout, also allow clearance for the
spout connection.
You can extend the distance between the between the diverter
and the braided hose connection with 1/2″copper piping below
the rim of the bath/whirlpool, but it may not be safe or practical.
A long run of piping will mean a long run of room-temperature
standing water when the handshower is first activated for use.

Secure long runs of piping to the underside of the deck or rim. If
the piping cannot be secured at a point near the diverter, secure
from underneath with lumber of other suitable support.

3. Preparation
Provide an access panel for all installations.
Allow for access to the connection between the shower
high-pressure hose and the shower interlock hose.
For easiest installation, do not install the bath unit until all
soldering (except supplies) is complete. Then install the bath and
connect the supplies.
If used, install the bath spout shank at this time according to the
spout installation instructions. If possible, do not install the
finished trim until all other installations and construction are
completed.
If possible, do not install the finished portion of the spout until
all other installation and construction is complete.
For spouts with a supply tee: Solder in an adapter and a 1/2″
copper tube. Cap to close the extra port.
Install the valve bodies according to the valve body installation
instructions.
Loosely secure the valve bodies.
Follow the handle installation instructions to temporarily
assemble the handles in order to adjust the valves to the proper
height before connecting the lines to the diverter or supply.

Preparation (cont.)
NOTE: The cartridge assembly is easier to remove before the
diverter is installed. You can remove the assembly now or after the
diverter installation.
Use a wrench to loosen the cartridge assembly from the diverter
body. Continue to unthread the assembly to remove.
Set the assembly aside. Protect the seals and O-rings from
becoming dirty, damaged, or misaligned.

4. Install the Diverter
NOTE: You may need assistance to align and secure the diverter.
Thread the mounting nut all the way down onto the diverter
body.
Slide the friction washer followed by the rubber washer over the
diverter body and down to the mounting nut.
Insert the diverter body through the deck/rim/wall.
Slide the washer onto the diverter body.
Thread the escutcheon onto the diverter body until the top of the
escutcheon is flush with the top of the diverter body. This will
allow ample clearance for proper handle function.
Align the inlets and outlets.
Hand tighten the mounting nut.

6. Install the Handshower
From the top of the bath or finished deck, insert the smaller end
of the interlock hose down into the hose guide and through the
mounting hole.
From the underside of the bath or finished deck, insert one
washer into the flexible hose. Thread the flexible hose into the
high pressure hose.
Insert one washer into the other end of the high pressure hose.
Connect the high pressure hose onto a vacuum breaker (if
installed), or onto the appropriate water source.
Run cold and hot water through the handshower hose to flush
out dirt and debris. Check for leaks.
Turn the cold and hot water supply off.
For an elbow installation: Insert one washer into the bottom of
the elbow assembly. Thread the bottom of the elbow assembly
onto the interlock hose. Insert a screen washer into the top of the
elbow assembly. Thread the handshower onto the elbow
assembly.
For an upright installation: Insert one screen washer into the end
of the handshower. Thread the handshower onto the handshower
hose.
To avoid kinking, be sure to remove any twist loops in the hose.
