11.5.6 Distillation Maintenance
You must strip the still at the end of each work day.
Caution
The condenser and still (sight-glass, distillation opening)
present a burn hazard
Sequence of the maintenance work:
When the last cleaning cycle has ended, start distillation maintenance P45:
+ + + The horn sounds at the end of the program and symbol 15
disappears.
Alternatively, you can start the distillation maintenance by entering 15E (before press ) while the
last cycle is still running (but the last pumping out to distillation step must have completed).
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.
Additional sequence of the maintenance work:
Let the still cool off (preferably overnight)
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
or place with the normal garbage.
You must dispose of the residues as special waste.
