11.5.6 Adsorption Filter Cartridge Maintenance

Observe safety regulations concerning the handling of solvent (see Point 2).
You must replace the cartridge when the pressure reaches 1.8 bar (26.1 psi).
When changing the cartridge, separate the cartridge filter (7) from the economy filter (6) by setting:
Ball-cock (1) open
Ball-cocks (2), (3), (4) closed
Sequence for the rest of the work:
- Open ball-cock (4), drain filter and let it sit and drain sufficiently
(overnight or weekend)
The filter vents automatically over ball valve (5).
- (On the next day) Loosen the tension clip on the filter housing and
open the housing (7)
- Unscrew the thumb screw and replace the cartridge (if necessary, replace the
sealing disc) and tighten the thumb screw again
- Check that the housing gasket sits correctly (replace gasket if necessary).
- Close the housing, mount the tension clip and then close ball-cock (4) on the filter drain.
Fill the cartridge filter with solvent during the next cycle.
Do this by closing ball-cock (1) and opening ball-cocks (2) and (3).
Then either run the filtration over the cartridge filter to the end or
separate the cartridge filter from the economy filter again.
Dispose of used filter cartridges as special waste in a way that avoids emissions!
If you precoated with filter powder, remove the empty bag from the cage.
If you want to use the additional cartridge filter, open
ball-cocks (2) and (3) again and close ball-cock (1).
