Section 7

Note: To extend the life of the tubing, rotate the pump tube 90 degrees in the pump housing after approximately 2/3 of the life has been realized (once the tube life has been determined through use).

Experience at a particular site will be your best indicator of tubing life. Visually inspect the tubing and rollers on a regular basis after initial installation to get a feel for what maintenance your site will require. Be sure to replace the pump tubing before it splits to prolong the life of the sampler and keep the work area free of contamination from the sample liquid.

The proper length of silicone tubing must be used in the pump body. An improper length can reduce the life of the tubing and pump rollers. Refer to Figure 29 for the correct length.

7.2.2Replacing Pump Tubing

1.To replace the pump tube, remove the four screws on the pump cover.

2.Remove the front cover of the pump housing.

3.Remove the existing tubing. Locate the black dot on the new tubing. The end of the tube that extends farthest beyond the black dot attaches to the stainless steel tubing connector.

4.Install the pump tube in the pump housing until the black dots are visible just outside the pump body.

5.After inserting the new pump tube, reinstall the front cover and secure it with the four screws until finger tight.

7.3 Upgrades, Repairs, General Maintenance

Only a qualified technician should service the sampler. For example, steps that require knowledge of CMOS electrostatic discharge precautions and advanced electronics training and should only be performed by a qualified technician. If you need assistance in performing any of the following service steps, contact the manufacturer.
