Place your sampler on a relatively flat surface. Placing it on a
steep incline may cause the sample to miss the bottle opening.
Note
Although the suction line can extend to a liquid source as many
as 99 feet from the sampler, note that the maximum lift for the
peristaltic pump with either the PTFE or vinyl line is 26 feet.
When installing the sampler, be sure the head - the vertical dis-
tance between the level of the liquid source and the pump - is
no greater than 26 feet. The pump will not be able to deliver
samples for heads of 26 feet or greater.
If it is necessary to enter the manhole to position the strainer
and suction line, observe standard safety precautions. Refer to
Appendix C for a discussion of safety considerations.
The sampler will automatically cease operation after all bottles
have been filled or after the programmed number of samples
have been placed in the composite container (or composite sam-
pling has been stopped by the float shut-off). When the sampling
routine has finished, the display will read "DONE."
