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 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 detergent solution foams or boils over, you can use a defoamer.
The amount to use is approximately 0.1 % of the filling quantity (either over the button trap or
using a separate pump). If the distillation unit boils over, empty and clean the water separator (if
necessary, distill the contents of the clean tank. The distillation cleans the condenser
automatically.
* With direct addition of steam, almost all of the perc is stripped off because the boiling point is
lowered.
