Owner's Manual
Installation procedure:
Please remember the following: Valves are shipped with batteries pre-installed and a cover over the sensor eye. When
necessary to remove batteries never attempt to remove batteries by pulling hard on battery wire.
1. Place tube sleeve over supply bib that is present in the wall.
2. Slide supply flange over tube sleeve, press against wall. Using Allen wrench fasten supply flange to tube sleeve.
3. Using plumber's putty, fasten stop to pipe bib.
4. Mount spud coupling (spud flange, rubber washer, thrust washer, spud nut) to urinal or toilet spud. Keep spud nut
loose in preparation for step 5.
5. Install flush connection to spud coupling by inserting connection through spud nut. Tighten spud nut
6. Insert vacuum breaker into flush connection as shown in drawing.
7. Run water through stop valve at high volume for 1-2 minutes in order to clear dirt and debris out of pipes
prior to installing flush valve. Use a container to capture running water.
8. Place flush valve on top of flush connection, mate valve body with stop valve.
9. Hand tighten both connection nut and stop nut a few turns each at a time. This will insure that the nuts are threaded
properly to their prospective male counter parts. (Do not cross thread).
10. Place heavy cloth over nuts in order to protect the finish and tighten using wrench.
11.
Loosen the Allen anchors using supplied wrench (1 or 2 turns), align sensor window so it is facing forward and
looking over toilet or urinal. Tighten Allen screw (Do not over tighten).
12. Turn water on and check for leaks.
13. Water flow rate is adjusted with flow adjuster screw within stop valve.
14. For urinal application turn water flow rate (DE method).
15. Remove cover that covers sensor window in order to begin operation.
Operation:
1. The sensor senses object (body) and begins blinking red light. The object must be present in front of sensor for 8-10
seconds in order to prevent accidental flushing.
2. Once object has left sensor area (toilet urinal stall) a delay of 2-3 seconds may occur after which toilet or urinal will
flush.
3. For manual operation depress push button (located atop valve) and release.
Please remember automatic toilets and urinals utilize presence sensors and not motion sensors. Moving object in
front of sensor rapidly will only delay or prevent proper flushing.
Sensor Range Setup:
Sensor range is factory preset and is not field adjustable.
Battery replacement:
Valve is shipped with 4 AA batteries pre-installed. When necessary to replace batteries:
1.
Unfasten upper Allen screw in the back of the valve, pull battery access cap off (have a towel handy to rap top cap
with towel. This will prevent damage to valve finish). Pull battery enclosure out of valve and disconnect be careful
not to cut battery wires.
2. Place batteries in the proper order. It is advisable to use high quality batteries for this task.
3. After batteries have been inserted in their proper order, re-plug battery compartment, place valve cap back on and
refasten Allen screw.
4. At this time the sensor will take a few moments to adjust to the room's environment after which the valve will be
ready for operation
