Section 2 Installation
Dangerous Locations – If you must enter a
manhole, confined space, or other dangerous
location to install the suction line and strainer,
observe standard safety precautions.
Support – The sampler should be installed on
a surface capable of safely supporting the
sampler, full liquid containers, and personnel.
AC Power – The mains line cord is the
disconnect device should you need to remove
power. Therefore, the electrical power outlet
should be accessible.
Environmental – The sampler is designed for
outdoor use. Refer to Table 1-2 for
environmental specifications. When possible,
avoid subjecting the sampler to chemical
attacks and direct sunlight.
Avoid Submersion – The sampler is rated
NEMA 4x (IP66), which does not protect from
submersion. In the event of submersion, liquid
entering the refrigeration system could
permanently damage the sampler; liquid
entering the bottle compartment could
contaminate the collected samples. Liquid
entering the electrical compartment for the
refrigeration system could result in a short
circuit and possible shock hazard.
Liquid Sample Collection Point – It is best
to keep the distance between the sampler pump
and the collection point as short as possible.
Also, the pump inlet should be located above
the liquid surface to be sampled with no liquid
traps. Gravity will aid suction line rinses and
allow the line to drain, thereby reducing the
