Your Kohler Electronic Valve
Design Features
Your new Kohler exposed electronic valve is precision engineered and
constructed of premium quality materials to provide trouble-free
operation even under the hardest water conditions.
The valve is designed specifically for use with 3/4″(19 mm) or 1-1/4″
(32 mm) top spud urinals as offered by Kohler Company and others.
1108712-5-D 4 Kohler Co.

Your Kohler Electronic Valve (cont.)
The valve is supplied with factory preset timing values. No
programming or adjustment is required.
Depending upon use,a9Vlithium battery can be expected to last for
two to three years before replacement is required.
Flush Operations
The exposed electronic valve provides the following flushing
operations:
Wave activated main flush operation: When a hand is waved
over the sensor, the valve provides a main flush.
Automatic 24-hour flush operation: After 24-hours of non-use,
the valve produces a full flush.
Low Battery Indication
The 9 V lithium battery can be expected to last for two to three years
before replacement is required. When the battery reaches a certain
point in its lifetime, the valve announces the low battery condition by
continuously flashing an LED whenever a user is in range. The battery
is easily replaced as described in the section ″Replace the Battery″in
this guide.
Replacement batteries can be purchased from drugstores or other stores
stocking batteries. The required battery is a standard 9 V lithium.
Seasonal Use
The exposed electronic valve is not designed for operation in freezing
conditions. If freezing conditions are expected, isolate and drain the
valve along with whatever other winterization steps are taken for the
facility.
Mobile Use
The exposed electronic valve is not designed for use in moving
environments such as boats.

from the control stop.
To close the stop valve: Turn the valve screw clockwise until the
end of travel is reached.
To open the stop valve: Turn the valve screw counterclockwise
until the end of travel is reached.
When done, place the cap on the control stop, then gently tap the
control stop into place with the screwdriver handle.

NOTICE: Do not pinch or kink the wires between the cap and the
valve body. If the wires are damaged, the unit may not operate.
Hold the cap vertically with the sensing holes down and align the
DC sensor with the cap.
Slide the DC sensor into the cap until the sensor eye aligns with
the hole in the cap. Ensure the sensor wires are not pinched.
Place the sensor strap over the DC sensor and tighten the screws
in the cap until snug.
Connect the DC sensor connector to the solenoid connector on the
valve. Ensure that the connector pair is fully seated.
Locate the connector assembly adjacent to the battery to prevent
pinching when the cap is reinstalled on the valve.
Place the cap on the valve body.
Secure the cap with the setscrew.
Verify that the valve functions correctly.
