Loading Door Venting; Distillation; Overfill Preventer In Still (Optional Equipment); Emission-Free Still Rake Out System - BÖWE P 12 Instruction Manual

7 Functional Units

7.15 Loading Door Venting

When the loading door is opened, the machine fan starts to run (on machines with Slimsorba, only the
Slimsorba fan). This fan prevents air that contains solvent from entering the area of the machine
operator during loading and unloading of the machine. The air that is drawn out of the cage is directed
over the air cooler before it leaves the machine. The cage is vented for 2 minutes, after which the horn
sounds to remind the operator to close the loading door soon.
On machines with integrated Slimsorba, the air drawn off is directed over the Slimsorba carbon bed after
the air cooler.

7.16 Distillation

The distillation unit consists of a still with ascending pipe and condenser.
The still is steam or electrically heated and equipped with an overfill preventer (optional equipment) and
still rinser. The still and the sight-glass are rinsed each time the still is pumped out. Use 13E to turn the
distillation heater on and off.
For information on still stripping and maintenance, see Point 11.

7.16.1 Overfill Preventer in Still (Optional Equipment)

A built-in sensor interrupts the pumping in process when the upper edge of the view-glass has been
reached. The horn sounds and the diagnostic message E 6425 is displayed. Delete the diagnostic
message with the "C" button. The display shows "par 21". Push the "START" button to pump excess
solvent to Tank I. The program continues.

7.17 Emission-Free Still Rake Out System

(Optional Equipment)
Emission-free still rake out is only possible with the economy filter if no filter powder is precoated.
With each distillation pump out process, the sludge pump pumps out the entire contents of the
still.
Use maintenance program P36 for the emission-free still rake out.
