11.5.9 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).
Attention: Perform maintenance work only when the machine has
been turned off and when the distillation blow-out is cold.
The green lamp must light up and the display on the
vacuum meter must have sunk to 0 bar (0 psi).
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 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
or place with the normal garbage.
You must dispose of the residues as special waste.
