3.1 Setting up the instrument
3.1.1 Packaging
The instrument is supplied in highly protective special packaging together
with the separately packed accessories. Keep this packaging, as only this
ensures safe transportation of the instrument.
3.1.2 Checks
Immediately after receipt, check whether the shipment has arrived com-
plete and without damage by comparing it with the delivery note.
3.1.3 Location
The instrument has been developed for operation indoors and may not be
used in explosive environments.
Place the instrument in a location of the laboratory which is suitable for
operation, free of vibrations, protected from corrosive atmosphere, and
contamination by chemicals.
The instrument should be protected against excessive temperature fluctu-
ations and direct sunlight.
3.2 Installing the inlet tubing and outlet tubing
As the inlet tubing and outlet tubing, two different tubing types are avail-
able. Both tubings are included in the scope of delivery:
￭ PVC tubing (6.1801.120), 2 x 2 m
￭ PTFE tubing (6.1812.000), 1 x 4 m
Note
Which of the two tubings to use depends largely on the solvent used.
PVC tubing is more flexible and has the advantage of making less noise
during the pumping operation. It must be noted that the PVC tubing is
not resistant to solvents.
Install the inlet tubing and outlet tubing as follows:
1 Cut the inlet tubing and outlet tubing to the suitable length.
