Tools and Materials
Before You Begin
CAUTION: Risk of personal injury. To eliminate the risk of
scalding, the water temperature should never be set above
120°F (49°C).
DANGER: Risk of scalding or other severe injury. Before
completing installation, the installer must set the maximum
water temperature setting of this valve to minimize the risks
associated with scalding hazards according to ASTM F 444.
CAUTION: Risk of scalding. This device has been calibrated
at the factory to ensure a safe maximum water temperature.
Any variance in settings or water inlet conditions from those
used during factory calibration may raise the discharge
temperature above the safe limit, and may present a scalding
hazard. Responsibility for installation and adjustment of this
device in accordance with these instructions lies with the
installer.
IMPORTANT! No minimum wall thickness is required if the wall
material is strong enough to support the trim. If the walls are less
than 1/2″(1.3 cm) thick, it is recommended reinforcement be added
to prevent the wall from flexing when the trim is tightened. Flex in
the wall will result in improper front plate installation.
Observe all local plumbing and building codes.

Before You Begin (cont.)
The finished wall or bath/shower unit must be installed prior to
installing this trim.
IMPORTANT! If you are installing the trim to a valve in a
back-to-back installation, before beginning the installation you must
determine which of the valve supplies are reversed (hot water
routed to cold side and valve rotated 180°).
If the trim will be installed on a valve with a back-to-back
installation with another valve, follow the corresponding
directions.
The valve shuts off by water pressure. Do not force the handle in
any direction. To turn the valve off, gently turn it clockwise to the
″OFF″position.
IMPORTANT! There are a number of steps devoted to correctly
orienting various parts. The various components must be kept
correctly oriented throughout the installation, for ease of installation.
Shut off the main water supply.
Kohler Co. reserves the right to make revisions in the design of
products without notice, as specified in the Price Book.

1. Determine the Wall Thickness
NOTE: The plaster guard must be in place for these steps.
NOTE: The finished wall must be installed before you perform these
steps.
NOTE: If the plaster guard is inside the finished wall, the wall is too
thick for the install and the valve needs to be moved forward.
NOTE: This trim is designed to allow for a 1-1/2″(3.8 cm) variation
in wall thickness.
Take a straight object such as a pencil and hold it along the
outside edge of the mud guard with the tip touching the finished
wall.
Either mark the spot where the top edge of the plaster guard and
the pencil meet or hold the pencil with your fingers at that spot.
Move the pencil to the inside of the plaster guard. Touch the tip
of the pencil to the bottom of the plaster guard at the deepest
point next to the area labeled ″1.″

Determine the Wall Thickness (cont.)
If the mark on the pencil or your fingers is even with the top
edge of the plaster guard or above it, go to the next section of
this installation.
If the mark or your finger is below the edge of the plaster
guard, perform the remaining steps:
Slide the pencil along the steps until the mark or your fingers are
even with the top edge of the plaster guard.
Note which area of the plaster guard the pencil is touching.
If the pencil is touching the step labeled ″1,″you will need to
add 1 spacer.
If the pencil is touching the step labeled ″2,″you will need to
add 2 spacers.

2. Install the Spacers
Remove the plaster guard.
Cut or break the mounting nut tool out of the center of the
plaster guard.
If you do not need to add spacers go to the next section.
To Install the Spacer(s)
Align the slots on each spacer with the tabs on the valve.
Slide the spacer or spacers onto the valve.
You will hear and/or feel each spacer snap into place.

3. Install the Stem Extension
Turn the valve to the off position by turning the stem clockwise
using the temporary shut-off knob.
Determine the correct stem extension for your installation:
•If no spacers were needed, the stem already installed is correct.
•If 1 spacer was installed, remove the thin wall stem and install
the medium wall stem.
•If 2 spacers were installed, remove the thin wall stem and install
the thick wall stem.
•The spline adapter should come installed in the correct position.
If the spline adapter comes off when the stem is removed, it must
be reinstalled correctly.
•To reinstall the spline adapter, position it with the seam in the 7
o’clock position.
NOTE: The stem must be correctly aligned for the rest of the
installation steps.

Install the Stem Extension (cont.)
Situate the timing mark at the 1 o’clock position. If the timing
mark is not aligned correctly, remove the stem and move it one
spline to reinstall it.
If the stem still does not align correctly, remove the stem and
remove the spline adapter, adjust it one spline, and reinstall it.
Repeat until the stem is perfectly aligned.
If the valve cartridge is flipped (hot and cold inlets reversed),
install the stem with the timing mark in the 7 o’clock position.
Confirm that the stem is correctly installed, with the timing mark
correctly positioned and the arms vertical and horizontal.

4. Install the Mounting Hub
Position the tab on the temperature adapter in the 6 o’clock
position.
Gently slide the mounting hub over the valve stem and into the
temperature adapter. The ″Up″imprint on the hub should be
situated in the 12 o’clock position.
Align the four slots in the hub base with the four tabs on the
temperature adapter. The coil can be turned to achieve the proper
alignment.
Firmly push the hub into place. There will be a noise as it snaps
into place.
Make sure all four slots are engaged.
Position the pin on the mounting hub assembly at approximately
the 7 o’clock position, directly above the first tooth on the
mounting hub assembly.

5. Install the Mounting Plate
Turn the volume control stem clockwise to the ″Off″position
using the shut-off knob (or gently with a pliers).
Position the mounting plate over the mounting hub with the ″UP″
imprint in the 12 o’clock position.
NOTE: There are two threaded holes in close proximity to each
other in the valve. For this trim, make sure the screws are threaded
into the threaded holes in the corners of the valve.
Insert the screws through the slots in the mounting plate and
thread them into the valve.
Thread the screws in until they are almost tight, but loose enough
to allow the plate to be adjusted horizontally.
Align the marks on the mounting plate with the knobs on the
stem by sliding the mounting plate left or right as needed.
Fully tighten the mounting screws.
Apply a small amount of adhesive caulk or sealant to the top and
sides of the mounting plate.
