Installation and Initial Operation
INFORMATION
The exit gas cooler only works with activated temperature con-
trol (Parameter Temperature ON).
3. Use your hands to check whether the exit gas cooler is begin-
ning to cool down. Open the control valve for water flow on the
basic unit, if necessary.
When the circuit is full, water escapes from the overflow on
the vessel jacket or cold finger and flows into the water outlet.
4.
Wait for min. 1 minute.
This ensures that no air is left in the temperature control cir-
cuit.

To test the stirrer, proceed as follows:
1. On the operating panel for the parameter Stirrer, set a low set-
point.
For further information about the different ranges of rotation

Switch the parameter on.
For the rest of the procedure, allow the bioreactor to run with the
temperature switched on and the stirrer running.
