bottle holder. B Extension module on the below the IC
instrument
Between the base plate and the 850 Profes-
sion IC.
C Extension module next to the IC instru-

Position the extension module in such a way that the capillary connections
can be kept as short as possible. If several extension modules are used,
then they should all be installed in the same location if possible – either
above, below or next to the IC instrument. If this is not possible, then the
extension modules that are located at greater distances from one another
must be connected with one another by means of the longer 6.2156.070
connection cable (available as optional accessory).
3.2 Mounting the extension module onto the IC instru-
ment
1 Switching off the IC instrument
Switch the IC instrument off and disconnect the mains cable.
2 Clearing the bottle holder
If there are bottles and other items on the bottle holder, remove
them.
3 Removing drainage tubings
Loosen the drainage tubing from the drainage tubing connector on
the bottle holder.
