Your Kohler Electronic Valve

Design Features

The valve is designed speciﬁcally for use with 1-1/2″(1.9 cm) top spud

toilets as offered by Kohler Company and others.

The valve is supplied with factory preset timing values. No

programming or adjustment is required.

1108709-5-C 4 Kohler Co.

Your Kohler Electronic Valve (cont.)

Depending upon use, the ″AA″alkaline batteries 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:

A wave activated main ﬂush operation: Shortly after the

individual departs the ﬁxture, the valve provides a main ﬂush

that lasts for several seconds.

An automatic 24-hour ﬂush operation: After 24-hours of non-use,

the valve produces a full ﬂush.

Low Battery Indication

The 1.5 volt ″AA″alkaline batteries 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 batteries are easily replaced as described in the section

″Replace the Batteries″in this guide.

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.

the old batteries in accordance with any applicable codes.

Remove and discard the old batteries. If necessary, use a small

ﬂat-blade screwdriver to pry the batteries from the battery holder.

Align the metal poles on the new battery to contact the metal

electrodes in the battery holder. Take care to properly position

each battery, as shown on the battery holder.

Insert four new 1.5 volt ″AA″alkaline batteries into the battery

holder.

NOTICE: Do not overtighten the screws. The plastic threads can be

easily damaged.

Reinstall the battery holder and battery cover. Retighten the

NOTE: The DC sensor must be installed as shown in the

illustration.

Hold the cap horizontally with the sensing holes down and align

the DC sensor with the cap.

Slide the DC sensor into the cap until the sensor eyes align with

the holes in the cap.

Using a 3/32″hex wrench, tighten the screw on the wedge lock

system (not shown) that holds the DC sensor in place in the cap.

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 sensor body to

prevent pinching when cap is reinstalled on the valve.

Place the cap on the valve body.

Align the sensor eyes toward the user.

NOTICE: Do not overtighten the setscrew. The plastic threads can be

easily damaged.

Secure the cap with the setscrew.

Open the control stop, reinstall the cap, then tighten ﬁrmly with a
