Installing the adsorption cartridges
For effective CO
2
removal, the air sucked through the degassing cell
should be as low in CO
2
as possible. To achieve this, the air is aspirated
through a CO
2
adsorption cartridge (6.2837.000) (30-4)..
Moisture can block the CO
2
adsorption cartridge. In order to prevent this,
a H
2
O adsorption cartridge (6.2837.010) (30-7) is connected upstream.
