Plumb the sampler
Install the intake tube in the middle of the sample stream (not near the surface or bottom) to make
sure that a representative sample is collected.
1. Connect the tubing to the sampler as shown in Figure 6 .
Note: Use connection kit 2186 if Teflon-lined tubing is used.
2. Install the intake tube and strainer in the main stream of the sample source where the water is
turbulent and well-mixed. Refer to Figure 7 .
• Make the intake tube as short as possible.
• Keep the intake tube at a maximum vertical slope so that the tube drains completely between
samples.
Note: If a vertical slope is not possible or if the tube is pressurized, disable the liquid sensor. Calibrate the
sample volume manually.
• Make sure that the intake tube is not pinched.
