Installation
• Make sure that the temperature at the site is within the
operating temperature range that is specified for the sampler.
• Make sure that the intake tube is as short as possible.
• Maximize the vertical slope of the intake tube from the sampler
to the sample source so that the tube drains completely. This
prevents cross-contamination of samples and freezing the tube.
Note: See Specifications on page 5 for limitations on transport velocity
and maximum vertical lift.
Note: If site conditions do not permit the intake tube to have a
downward slope, or if the line is pressurized, disable the liquid sensor
and calibrate the sample volume (
section 4.8.2 on page 46 ).
• Install the strainer in the middle of the sample stream (not near
the surface or bottom) to make sure that a representative
sample is collected.
