11.5.7 Distillation Maintenance

You must strip the still at the end of each work day.
Attention: Because of the hot surfaces, there is a burn hazard on
the
condenser and still (sight-glass, distillation opening).
Caution
Sequence of the maintenance work:
- If you cannot see any flowing solvent condensate in the water separator sight-glass, start
distillation maintenance P36.
- Press the STOP button when the horn sounds at the end of the program.
On machines with an emission-free still rake out system, the distillation residue was automatically
pumped into the disposal vessel. The maintenance is complete.
On machines without an emission-free still rake out system, you must perform additional maintenance
work.
Attention: Perform maintenance work only when the machine has
been turned off and when the distillation blow-out is cold.
Check the liquid level before opening the still door.
Open the door carefully.
Sequence for additional maintenance work:
- Let the still cool off (preferably over night)
- The next morning, hang the clean-out trough on to the still.
- Open the door of the still and rake out the distillation residues
- Clean the overfill preventer probe
- Close the door of the still tightly
Attention: Do not drain distillation residues into the sewer system
Put neutralization agent into the still.
When necessary, you must also perform maintenance work on machines with an emission-free still rake
out system with the still door open (lint balls, caked-on dirt).
Sequence of the maintenance work:
- Select P36 and press the START button
- The number 8 appears in the display; now enter 0 and press E
- Restart (distillation program starts running without rinsing)
- When the horn sounds at the end of the program, press the STOP button
- Let the still cool over night
Now perform the maintenance work that is described under "Sequence for additional
-
maintenance work".
or place with the normal garbage.
