Installation
•
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
tube freeze.
Note: See
Setting up the intake line and strainer on page 31
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 (
Volume Calibration on
page 135
).
•
Install the strainer in the middle of the sample stream (not near the surface or the
bottom) to make sure that a representative sample is collected.
•
Install the sampler on a level surface.
•
Secure the AWRS cabinet to its mounting surface using the two anchor brackets
provided and the customer supplied hardware. The instrument comes with two
anchor brackets already installed. An optional kit with two additional brackets
(6613100) can be ordered if the user wishes to secure all four corners of the
instrument. Refer to
.
Note: A
3
/
8
” bolt or stud or bigger can be used to secure each anchor bracket to the mounting
surface.
•
Use the leveling feet to level the sampler. Turn the leveling feet clockwise to raise
the sampler.
The interior floor of the sampler cabinet is sloped for easy draining. A ½ in. - 14 NPT
female thread is provided on the bottom of the enclosure to direct liquids to a drain or
specific area away from the sampler cabinet.
