Page 22: Minimum Space Requirements
Isco 4700 Refrigerated Sampler Section 2 Installation • 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.
Page 23: Installing A Bottle Kit
2.4 Installing a Bottle Kit The 4700 sampler can hold 1, 2, 4, and 24 bottles. Each of these bottle configurations are supplied as a kit (see Table 2-1), which is normally ordered with the sampler or when you desire to change the bottle configuration.

Isco 4700 Refrigerated Sampler Section 2 Installation If you have selected a multi-bottle kit, first install the distributor arm and discharge tube (Section 2.4.1), then refer to the instruc- tions for your selected bottle configuration: • 24 Bottle configurations – section 2.4.2 •...
Page 25 Then, retest the tube at other arm positions. Note You can order replacement discharge tubes from Teledyne Isco. Order part number 60-9003-279 for a single tube. You can also order bulk tubing rolls from which you can cut to 20 inches (51 cm).

Page 29: Attaching The Suction Line
The sampler uses a -inch ID suction line of Line lengths from 3 to 99 feet. Teledyne Isco offers vinyl or FEP-lined suction lines. The FEP-lined tubing has a polyethylene jacket to protect it from kinks and abrasions.
Page 30: Vinyl Suction Line
Isco 4700 Refrigerated Sampler Section 2 Installation When accurate, repeatable sample volumes are important, use care to cut the suction line to the correct increments: • When the sampler is using metric units of measure, cut the line in 0.1 m increments. For instance, cut 4.2 m, not 4.26 m.

Page 32: Attaching A Strainer
Isco 4700 Refrigerated Sampler Section 2 Installation 2.6 Attaching a Strainer To select the right strainer for your application, see Table 2-2 and Figure 2-10. To attach the strainer to the suction line, carefully screw the strainer’s threaded connector into the suction line. If attaching the strainer to an FEP-lined suction line, heat the end of the suction line before threading the strainer into the line.
