Installation

DANGER

Only qualified personnel should conduct the installation tasks described in this section of the manual

3.1 Unpacking the Instrument

Remove the sampler from the shipping carton and inspect it for any damage. Contact Hach Customer Service at 1-800-227-4224 if any items are missing or damaged.

3.2 Selecting the Installation Site

The sampler is completely self-contained and may be located indoors or outdoors without protection, between 0 to 50 °C (32 to 120 °F). Follow the guidelines below and Figure 3 to allow complete drainage of the intake line and prevent cross-contamination between samples.

•Install the sampler as close to the source as site conditions permit. This will increase pump tube life and optimize overall sampler performance.

•Mount the sampler to a stable flat surface using the wall mounting bracket, Cat. No. 3596 (Figure 4).

•Install the sampler above the sample source, with the intake tubing sloping downward to the sample.

•Make sure the tubing is free of kinks or loops.
