1. Determine the Sensor Location

Kohler Co. 3 1124216-2-B

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)
3″ (76 mm) 1-9/16″ (40 mm)
4″ (102 mm) 2″ (51 mm)
5″ (127 mm) 2-3/8″ (60 mm)
6″ (151 mm) 2-9/16″ (65 mm)

2x4 Stud Framing

Sink Height

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.
