Determine the Sensor Location (cont.)
IMPORTANT! It is critical for proper operation that the sensor be installed with the motion zone clear of any obstructions, including the edge of the countertop or the bathroom sink.
NOTE: Before installation, consult the specification sheet for the spout to determine the correct wall rough-in for your installation.
Measure the distance (X) from the finished wall to the inside edge of the countertop or bathroom sink.
Determine the sensor height (Y) using the chart below. If you cannot determine Y from the chart, use the formula .5″ + X(0.364) to determine (Y).
If dimension X is: |
Then the sensor height (Y) is: |
1″ (25 mm) |
7/8″ (48 mm) |
2″ (51 mm) |
1-1/4″ (32 mm) |

2. Prepare the Site
IMPORTANT! The valve requires special framing and support considerations. Consult the specification sheet for the spout that will be installed with your valve at www.kohler.com for specific dimensions.
NOTE: Mount the valve with the sensor at the height determined in the previous step.
NOTE: A suggested framing example is shown. Each installation may have different framing requirements than those shown.
Construct the framing for your installation.
If a thermostatic mixing valve will be included with your installation, install the valve now following the directions provided with the valve.
3. Secure the Valve
IMPORTANT! Make sure the location of the valve is correct before securing it in place. The centerline of the drain and faucet should be in line with each other.

4. Install the Supplies
Install 1/2″ supply pipe to the valve assembly.
At the point where the supply will exit the wall, install a drop ear ell flush or slightly behind the finished wall.
Feed the sensor wire through the sensor mount and plaster guard, leaving 1-1/2″ (38 mm) minimum of exposed wire protruding.
Connect the sensor wire harness to the wall.
Temporarily connect the water supply to the supply ell.
Turn on the water.
Check the system for leaks.
Turn off the water.
Install the finished wall.
NOTE: The diameter of the faucet hole cutout is 1-3/4″ (44 mm). The diameter of the sensor hole cutout is 1-3/8″ (35 mm).

6. Install the Control Box
NOTE: Locate the sensor box underneath the countertop, between the ell and the water supply stop.
NOTE: Do not connect the control box wiring in this step. Drill a 1/2″ (13 mm) hole at the control box location.
Route the sensor wire through the hole.
Remove the control box cover. Keep the screws and cover.
Mark the screw hole locations using the control box as a template. Make sure the wire harness hole in the wall is covered by the box.
Install appropriate wall anchors (not provided) at the marks.
Feed the wires through the back of the valve and control box.
Attach the control box to the wall with two screws (not provided).

7. Install the Supplies
IMPORTANT! It is critical that the inlet and outlet holes be aligned correctly. The inlet hole is round, the outlet hole is hex shaped. There is a label on the outlet side identifying it.
Slide the escutcheon over the elbow and attach the elbow to the ell.
Slide the escutcheon tight against the wall.
Attach one end of the hose to the elbow and attach the other end of the hose to the control box outlet.
Attach the supply hose to the control box inlet.
NOTE: If the water supply does not route through a mixing valve, the water from the faucet will be cold.
Attach the other end of the line to a thermostatic mixing valve (recommended), mixing valve, or supply stop.
