6100CR Refrigerated Sampler Section 3 Installation of the Sampler Flow Arrow Figure 3-3 Filter, Disassembled Filter Screen Element Arrow 3.1.2 Preparation of Tubing and Connectors The tubing used for the sample delivery line is terminated with specially-designed connectors in an optimized system that is both leak-tight and easy to install. Figure 3-4 Fitting, Disassembled Note Normally there is no need to disassemble the tubing fittings. In fact, it is better to avoid disassembly, as it increases the risk of loss of small internal parts, or of incorrect reassembly. In actual practice, it is only necessary to groove the tubing with the scoring tool, insert the tubing into the fitting after loosening the blue end, and then re-tighten to secure the tubing. Make sure the tubing bottoms out in the fitting. Tighten the fitting nut only to the point where the nut just stops at the ridge of the fitting body. Do not overtighten; the fittings are Teflon ® and the threads will be destroyed! 3-4
6100CR Refrigerated Sampler Section 3 Installation of the Sampler Pull handle away before inserting tubing. Figure 3-5 The Scoring Tool Insert tubing here until it bottoms out, push handle back in; then rotate tool to score tubing. The scoring tool cuts a precise groove in the surface of the tubing at the right distance from the end. This ensures that tubing will be properly seated and locked inside the connector when the blue fitting is tightened. The fittings in Figure 3-4 have two ferrules, a thick one and a thin one. The thin one locks the tubing by seating in the groove. The thick one seals the connection between fitting and tubing. If you must disassemble the fittings for any reason (and this should be avoided), note the orientation and position of the ferrules when reassembling them. See Figure 3-4. Note Where the tubing fittings are screwed into other threaded fittings, apply Teflon ® tape to the threads before assembly to prevent leaks. Proper tightening of the fittings is reached when the blue nut just touches the clear fitting. 3.1.3 Tubing Connection from Filter to Regulator Because the 6100CR cannot be shipped with the filter installed or the tubing connected, it will be necessary to connect a piece of tubing between the filter outlet (see Figure 3-1) and the pressure regulator. 3-5
