6. Connect the top of the intake hose to the volume control tube and tighten
the hose clamp (FIGURE 7-2 ).
7. Route the hose so that it has a near continuous slope from the sampler to
the source liquid. This keeps the hose clear and fully drained.
8. Put the sinker end of the intake hose into the water body to be sampled,
ensuring at least 3-inch depth. The sinker/strainer needs to be placed at a
depth that ensures it will remain submerged regardless of the flow
velocities.
9. If you do not know the necessary purge times, run the Auto Deploy routine
by pushing and holding the Manual Control button until the sampler
begins running (approximately 5 s (FIGURE 7-3 )). The Auto Deploy
routine sets the purge and the vacuum times based on the length of the
hose and the change in height between the sampler and the water source.
Wait for the sampler to stop before proceeding to Step 10.
10. Running the Auto Deploy routine drops a sample into one of the sample
bottles. If you do not want this volume as part of your final sample count,
remove the control section of the sampler and empty the sample just
collected. If necessary, replace with a clean bottle.
11. Push the Manual Control button once (FIGURE 7-3 ) to Service the
sampler and reset the sample count to 0.
12. Configure the sampler based on a chosen control type (see Section 8.2 ,
Deployment Procedures for Each Control Type
(p. 28)
).
13. If controlling the sampler with a datalogger or another external device,
connect the PVS5120CBL cable to the Signals connector on the Control
Panel (FIGURE 7-3 ), and then wire the cable to the datalogger or MD485.
Wiring is specific to a given control type. Please see the section on your
control type for wiring directions.
14. If using a datalogger, access LoggerNet and do the following (assumes
knowledge of using LoggerNet to setup the datalogger and connect either
via a direct connection or remote connection):
a. From the
LoggerNet Connect
window, click Connect | Collect Now
to collect any data on the datalogger.
b. From the Connect screen, click the Send New button. Browse to find
the datalogger program that controls the sampler; click Open | Send .
