7.1.3 Steps for Field Deployment
Once the sampler is positioned complete the following steps for deployment.
1. Loosen the brass nut to set the volume control tube to the approximate
volume required for collection by aligning the base of the tube with the
graduated marking on the metering chamber (FIGURE 7-2 ). It is best to
collect this volume and measure at least once to make sure it matches
expectations. If necessary, adjust the tube up or down to obtain the desired
collection volume.
2. Set the height of the conductivity rod (FIGURE 7-2 ). The bottom of the
conductivity rod must be higher in the metering chamber than the volume
control tube (at least 1.3 cm (0.5 in)), but below the bottom of the float
valve barrier.

3. Connect the positive lead (+) to the top of the conductivity rod (yellow
cap).
4. Connect the battery.
a. If using an internal battery, place it in the mount and connect the red
and black leads to the matching terminals. Also connect the yellow
caps with the fuse.
b. If using an external battery, make sure the external power cable is
stripped and the correct leads are in place to connect the battery.
Connect the external power cable to the Power connector on the
Control Panel (FIGURE 7-3 ).
5. Turn on the sampler and set the three-way switch on the control panel to
the power source being used (FIGURE 7-3 ). If powered correctly, the
green power LED lights for several seconds and starts blinking green once
per second.
