5.3.3 Storage tank connection

To connect the storage tanks, proceed as follows:

Cut the solaﬂex tube into pieces of the appropriate length (use an acid resistant tube, if acid is •

dosed).

Insert a PTFE suction tube into the solaﬂex tube.•

Push an EPDM sealing ring over the solaﬂex tube.•

Now fasten the tubes to the tank with the red screw cover.•

Connect the tubes at the appropriate connections at the instrument side and secure them with the •

clamps.

The “H

O” storage tank may be used to feed both the steam generator pump as well as the sample

tube pump. For this purpose the Y hose coupling can be used.

All pumps are self-priming, no overpressure is necessary at the tanks.

ATTENTION

To ensure proper system functioning, consider the following:

Use only distilled water for the H•

O storage tank to keep the steam generator maintenance-free.

Make sure that the tanks are connected correctly. If the wrong tank (e. g. reagent tank containing •

NaOH) is connected to the pump labelled „H

O steam“, the steam generator will be damaged.
