4.)
Insert the flush valve tailpiece
(B)
into the stop valve
(A)
and hand tighten the lock nut
(D)
to the stop valve. Plumb
the entire unit.
5.)
Determine the length of vacuum breaker tube
(F)
required to join the flush valve and fixture spud. Cut the
vacuum breaker tube, if required, to this length. Assemble
the vacuum breaker tube assembly and spud nut assembly
to the flush valve and fixture spud.
6.)
Hand tighten spud nut
(G)
and vacuum breaker tube nut
(H)
to fixture and flush valve. Adjust the valve assembly for
plumb. Tighten fixture spud nut
(G)
, vacuum breaker tube
nut
(H)
and lock nut
(D)
with a wrench.
Do not turn water on
until batteries are inserted – see 7.

7.) ACTIVATION
Using the 5/64" Allen wrench supplied with the valve, remove
the two 6-32 button head screws holding the top assembly
in place. Be sure to place the screws somewhere safe so
they don’t get lost.
Remove the top cover carefully and disconnect the solenoid
wire connector
(J)
from the bulkhead connector
(K)
. The
cover and battery case can now be taken to an appropriate
work area to install the AA cell batteries provided.
Remove the battery box cover screw using the 1/8” allen
wrench provided. Turn the top assembly upside down and
the screw will drop down and can be used to pull the cover
off. Load the four heavy duty AA alkaline batteries following
the battery orientation guide on the battery box cover. Note
that the coil springs always contact the flat (negative) end of
the battery. Insert the solenoid wire connector
(J)
into the
bulkhead connector
(K)
. Note that there are flats on the
plugs that must align. Align and secure the battery case lid
and gasket the with screw provided. Secure the top
assembly to the valve housing using the original screws.
Once this is completed, remove and discard the protective
label
(L)
from in front of the lens.
Normal valve operation will occur when the valve senses an
object (person). The LED will blink dimly four times about a
second apart. There will be a pause and then a double
blink. At that point the valve is charged. When the object
leaves the view of the sensor, the valve will activate. This six
second sensing cycle will prevent the valve from flushing
needlessly when someone walks by.
If special circumstances require adjustment of the sensing
distance, see Appendix A - Changing Activation Distance.
