Section 2 Installation
Appendix B of the Installation and Operation
guide for a discussion of safety considerations.
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 – Although the control
panel will resist damage (rated NEMA 4x, 6;
IP 67), the refrigerator system and bottle
compartment cannot prevent the liquid from
entering. Liquid entering the refrigeration
system might permanently damage the
sampler; liquid entering the bottle
compartment might contaminate the collected
samples. Liquid entering the electrical
compartment for the refrigeration system
might 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.
The shorter distance will increase pumping
efficiency and pump tubing life. Also, the pump
inlet should be located above the liquid surface.
Gravity will aid suction line rinses and allow
