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. Doing so would allow cross flow between the hot and
cold water supplies and 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.
This diverter can be installed to decks with a maximum thickness
of 1-1/4″(32 mm).
Carefully inspect waste and supply tubing for any sign of
damage. Replace if needed.
You can extend the distance 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.
This diverter can be used in either a deck-mount or wall-mount
installation. Refer to the ″Diverter Configurations″section for any
special considerations.
Do not install spouts with flow restrictors or handheld shower
units on the large (5/8″OD) bath outlet.

Before You Begin (cont.)
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.

Default flow is through this port.
The remaining two ports are for the hot and cold water inlet
supplies. They are interchangeable. If only one of these ports is
needed, cap the other port.
Configurations for Wall-Mount Installations
When diverting between the bath spout and handshower (or
showerhead):
The small port is for the handshower (or showerhead).

2. Piping Configurations
Verify the location of the components and the orientation of all
ports.
Decide in advance on the location and orientation of the diverter.
The locations 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 the 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 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
the piping from underneath with lumber or 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.
NOTE: 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.
For spouts with a supply tee: Add an adapter and a 1/2″copper
tube. Secure with solder. 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 to adjust the valves to the proper height.
Adjust the valve height before connecting the lines to the diverter
or supply.
NOTE: The cartridge assembly is easier to remove before the
diverter is installed. You can remove the assembly now or after the
diverter installation.

4. Install the Diverter
For Finished Deck Installations
At the diverter install location, drill a 1-1/2″(38 mm) hole.
For All Installations
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
escutcheon bottoms out on the diverter body. This will allow
ample clearance for proper handle function.
Align the inlets and outlets.
Hand tighten the mounting nut.

5. Complete the Diverter Installation
CAUTION: Risk of product damage. Verify that the diverter body
is secure before removing the cartridge. If not secured, the process
of removing the cartridge may damage the pipe and connections.
CAUTION: Risk of product damage. Excessive heat will damage
the internal plastic components. Do not apply excessive heat while
soldering. Direct the torch flame away from the brass body. Only
apply direct heat to the connectors and extensions.
IMPORTANT! If there is limited access to the solder connections, or
if any other risk of excessive heat being applied to the brass body
exists, remove the cartridge prior to soldering. If you remove the
cartridge, protect the seals and O-rings from becoming dirty,
damaged, or misaligned.
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.
If not already removed, remove the diverter cartridge assembly.
Dry fit all piping and connectors.
Solder piping for the optional spout or wall shower.
