sional IC Vario:

The base tray and bottle holder come fully assembled on a new ion chro-
matograph. If you wished to install an extension module on the ion chro-
matograph, you would have to remove the bottle holder and put it back
on top of the topmost instrument. If you wished to install an extension
module below the ion chromatograph, you would have to remove the
base tray and set it under the lowest instrument.

The base tray must be removed if you want to install another instrument
under the IC instrument.
CAUTION
Do not allow capillaries or leak sensor cables to be pinched!
Pinches in the leak sensor cable or the capillaries fed through the guide
ducts between the base tray and the instrument may lead to malfunc-
tions.
Unplug the leak sensor cable. Remove all of the capillaries from the
capillary ducts.
