Saving energy
For heating baths there are various ways to save energy. By using floating balls in the water bath,
evaporation of water is reduced. As a result, the bath heating has to switch on less often. This
measure helps to save up to 50 % of energy. At the same time approximately 70 % less water is
used. Additionally, a cover is available to put over the heating bath during operation which also saves
energy between distillations.

NOTE
Turn on the heating bath about 10 –15 minutes before starting the distillation, since the bath has a
certain warm-up time. Turn off the heating bath after a distillation.
ATTENTION
As soon as the power plug is connected and the mains switch is turned on, the bath starts heating if
the actual temperature is below the set temperature. For this reason, make sure that there is always
heating medium in the bath to prevent instrument damage.
5 .4 Glass assembly
To install the glass assembly, consider the following:
• To fasten the flanges you do not have to remove the flange screwed connection (position
e
in
Fig. 5.3). Just open the flange screwed connection wide enough, so that the flange can be
pushed through.
• You can also secure the glass assemblies V, S, C, E, CR, BY using the corresponding optional
support rod.
• Secure the receiving flask with the clip provided for this purpose.
ATTENTION
Check the glassware for damages prior to each operation and use only glassware that is in perfect
condition. Glassware with cracks, stars or other damages can break during operation.
NOTE
To achieve optimum tightness of the system, all joints on the condenser side must be greased.
