programming or adjustment is required.

1140767-5-A 4 Kohler Co.

Your Kohler Electronic Valve (cont.)

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: Shortly after the individual

departs the ﬁxture, the valve provides a main ﬂush that lasts for

several seconds.

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.
