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.
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:
An automatic 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 ″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.
Replacement batteries can be purchased from drugstores or other stores
stocking batteries. The batteries are standard 1.5 volt ″AA″alkaline
cells (four required).
Seasonal Use
