When changing the cartridge, separate the cartridge filter (7) from the economy filter (6) by setting:
Ball valve (1) open
Ball valves (2), (3), (4) closed
Sequence for the rest of the work:
- Open ball valve (4), drain filter and let it sit and drain sufficiently
(over night or weekend)
The filter venting takes place automatically over ball valve (5).
- (The next day) Loose the tension clip on the filter housing and open the housing
housing (7)
- Unscrew the thumb screw, 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 valve (4) on the filter drain.
Fill the cartridge filter with solvent during the next cycle. Do this by closing ball valve (1) and opening ball
valves (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!
