These pipes contain a small amount of caustic soda. Take care
when handling the pipe and observe the information on the
label or packaging. In particular, mechanical loads should be
avoided when connecting the pipes. The two plugs on the pipe
connection should be removed before connecting the pipe. These
plugs should be attached to the connections immediately after use.
Do not throw the pipe into your normal domestic rubbish. It should
be disposed of using special disposal services.
• Connect the CO
and the reducing adapter.
• Connect the other side of the CO
output via the connection pipe and reducing adapter

(green connection).
• Ensure that pump movements are slow because the absorption
material needs a certain time to absorb (gas speed should not be
too high).
• Rinse the probe for a few minutes with CO
