11.5.9.1. Emission-free Distillation System Maintenance (Optional Equipment)

Distillation residues can be pumped off into a disposal vessel using an additional sludge pump. When the
still maintenance is finished, ventilate the still after the distillation system has cooled off (green lamp).
Now you can pump off the residue with program P55.
Remarks on distillation:
Fill the still only up to the lower edge of the sight-glass.
When solvent containing water is distilled, the distillate becomes slightly cloudy as a result of the water
traces.
The distillation performance is reduced if you do not remove distillation residues from the still daily. This
also increases the risk of boiling over and increases the solvent consumption.
When operating with Economy filters without filter powder, the distillation residue is liquid.
This means that there will not be an increase in the consumption of solvent involved if the distillation
equipment is used correctly.
If the distillation unit boils over, empty and clean the water separator and the extraction tank with program
P54 (if necessary, distill the contents of the clean tank). The distillation cleans the condenser and the
flash tank automatically.
