11.5.4 Safety Separator (Optional Equipment)
The process water is drained out of the safety separator to the process water purification over the stop
valve (4). The correct time to do this is when the liquid level lies in the upper third of the sight-glass (7).
The solvent level must still be under the drain pipe (4)
Attention: Only operate the stop valve (5) when pumping to the still.
When needed, you can completely drain the safety separate with the stop valve (5).
Before draining the process water over valve (4), open valve (5) for a short time to
pump the discharged solvent to the still.
Dispose of the process water according to the regulations in your country.
