To connect the suction and pressure line, please loosen the union nut of the compression ring
fitting counter clockwise. Be sure to remove the union nut carefully from the fitting. There is a
loose clamp ring inside the union nut.
Slide the nut over the connecting tube.
Slide the clamp ring with the thicker bulge facing the nut, over the connecting tube.
Slide the connecting tube on the support nipple of the fitting.
Hand-tighten the nut. The connecting tube is now slip-proof and pressure-tight mounted to the
tube connection fitting.
Suction and pressure lines need to be installed in such a way that the pump is protected against
ingress of condensate or dust.
Note
Because of compression of sample gases, it is possible that condensate
builds up in the pressure line. This pressure must be reduced.
For example, reduce the pressure with a valve in the pressure line upstream
of the pump or with the integrated needle valve.
Start up
Before commissioning, be sure to comply with all applicable facility- and process-specific safety
measures.
Make sure to operate the pump for the intended use described in chapter 5 only.
Before commissioning, be sure to comply with all applicable safety regulations and measures of the
involved sample gases. The materials of the pump, which are in contact with the sample gas, need to
be suitable for the used sample gas. Before operating the pump, make sure that the materials of the
pump head, bellows and valves (for pump materials: see chapter 8 Technical data ) are suitable for the
used sample gas.
Follow these instructions before initial start-up:
Ensure that the pump is securely tightened to the surface.
Only sample gas which withstands the pressure and temperature within the pump and does not
built-up condensate is suitable for operation.
Make sure that the pump does not start-up against pressure or vacuum.
Before start-up and restarting, atmospheric pressure must be present in the suction and pressure
lines. Even when the power has been cut off for only a short period, the suction and pressure
lines need to have atmospheric pressure. After a pump standstill, the pressure in the sample gas
lines needs to be set back to atmospheric pressure.
Never exceed the maximum permitted operating pressure pressure (for details see chapter 8
Technical data ).
Only insert a sample gas flow controller or restriction device into the suction line. This protects
the pump bellows from damages, and prevents the pressure from exceeding the maximum per-
mitted operating value.
Monitor the pressure, when a sample gas flow controller or restriction device is inserted in the
suction line. This prevents the pressure to exceed the maximum permitted operating pressure.
Monitor the pressure if necessary.
