872 Extension Module Suppression – MCS
3.7.3 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) (11-4)..
Moisture can block the CO
2
adsorption cartridge. In order to prevent this,
a H
2
O adsorption cartridge (6.2837.010) (11-7) is connected upstream.
