Still (Electrically Heated) - BÖWE P12 Instruction Manual

6. Operation

6.1.10. Still (Electrically Heated)

If your machine has electrically heated distillation, you must first fill the steam chest with water.
Remove screw-in plugs (1) + (4), open aeration valve (2),
fill in water up to the overflow, replace screw-in plug (1) so that it seals tightly
(do not use hemp, use only PTFE tape).
Start "Still maintenance" (P45). Wait approximately 15 minutes until steam comes out of the
aeration valve (2). Then close the aeration valve (2). Screw in the screw-in plug (4) again. Stop P45.
If the system is correctly aerated, the operating pressure will be 2.5 - 3.5 bar.
Switching pressure on the pressure control switch: ON 5.2 bar OFF 5.6 bar
With proper aeration and sealing, the pressure gauge (3) shows underpressure of approximately
-0.5 bar when the system is cold.
This is an important prerequisite for proper operation (good distillation performance)
Attention: With the electrically heated version, a permanent 2-bath procedure
is not possible because of the reduction in performance!
