Cong Prima 2M - manual 27
The dew point analyzer is mounted as follows:
Attach the CP 2M using the eight M8 bolts included with delivery;
Close the fine-control valve (9) using a screwdriver (illus. 15, pos. 2). This requires removal
of the protective cap (illus. 15, pos.1);
Slowly move the handle of the sampling device to the open position;
Check the seal of the connecting elements. To do this, fill the measuring chamber of the
analyzer with sample gas under operating pressure. Next spread a soapy emulsion on all of
the connecting elements. If small bubbles begin to form it is an indication that the seal at that
point is not airtight and must be reseated;
Complete electrical installation in accordance with Appendix A;
Ground the analyzer. Connect the grounding terminal of the CP 2M to the grounding bus
using an insulated copper conductor with a minimum cross-section of 1.5mm
2;
Connect a rotameter to the outlet of the fine control valve (9). The rotameter is not included
with delivery and must be ordered separately. Using the rotameter as a reference, set the
gas flow to 0.3–0.5 Nl/min. The outlet (Swagelok/ Dk-Lok) ,is outfitted to accept an locking
tube connection with an outer diameter of 6mm
Remove the rotameter and attach a locking tube (not included with delivery) in its place
providing a pathway for the sample gas flow. Replace the protective cap on the fine-control
valve (illus. 15, pos.1);
Erect the sunshade or protective hood in accordance with the climate conditions.

To uninstall the Cong Prima 2M, follow these steps in the reverse order. After the analyzer
has been removed the gas feed element must be protected from dirt, dust, and water by
covering it with the protective lid (included with delivery).
Attention!
If the composition of the gas has very little liquid aerosols and
accompanying substances or has already been filtered, outflow through the
fine control valve may be dispensed with.
