See Figure 4 and follow the simple guidelines below to allow complete
drainage of the intake line and prevent cross-contamination between samples.
• Install the sampler as close to the sample source as site conditions
permit. This will increase pump tube life and optimize overall sampler
performance.
• Install the sampler above the sample source, with the intake tubing
sloping downward to the sample.
• Make sure that the intake tubing is free of kinks or loops.
Figure 4 Setting Up the Instrument
1. Slope tubing down to source (no
loops, kinks, or excessive tubing) 2. Place sampler on a level surface. 3. Locate strainer in an area of
turbulent and well mixed flow.
