Inlet Shut-Off Valve Kit 239114 is available. Parts
included in the kit are marked with a dagger, for
example (2{), in the Parts Lists on page 12 and in
Fig. 4. In addition to the part marked with a dagger,
the kit includes the following: 1/4-in tube x 1/8 npt tube
connector, 3/4-in close SST nipple, brass tube tee, and
sleeveless bushing.
You should use this second shut-off valve kit for any
pressure- or gravity-fed applications. If a diaphragm
failure occurs in a pressure- or gravity-fed application,
even after the leak detector shuts off the air supply to
the pump it is possible for fluid to be pushed through
the failed diaphragm and through the pump exhaust,
and it could overflow the leak detector. The second
shut-off valve in Inlet Shut-Off Valve Kit 239114, when
activated, stops any fluid from entering the leak
detector when the pump is shut down.

To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
Relieve the pressure. Install the new shut-off valve
(1{) at the leak detector inlet. Run the original air line
(2) from the tee (Z) to the original shut-off valve (1).
Run the new air line (2{) from the tee to the new
shut-off valve (1{) as shown in Fig. 4. Connect the
pump exhaust line to the new shut-off valve.
If a spill occurs, see Cleanup After a Leak on
