OBSTRUCTIONS
If you encounter an obstruction that
requires you to break prime (remove the
filter extension tubes from the water), it
can be done several times within a tran-
sect if the appropriate technique is fol-
lowed.
1. When an obstruction is encountered,
press the Start/Stop button to stop the
pump, but leave the extension tubes in
the water.
2. Quickly rotate the pole and invert the
filter housings, retaining as much water
in the extension tubes as possible.
3. Move around the obstruction to the next point in your sampling transect.
4. Press the Start/Stop button while simultaneously flipping the pole back into the
sampling position with the extension tubes in the water.
Note:
when the pole is in-
verted, the remote control is upside down; it may require some practice to press the
start button and flip simultaneously.
5. If prime is not fully broken (i.e., water not fully drained from extension tubes), then
the system will continue filtering without issue. If the filters run dry in this process
you may have trouble re-priming the pump with wetted filter membranes.
