3.1 Setting up the instrument
3.1.1 Packaging
The instrument is supplied in protective packaging together with the sepa-
rately 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 and free of vibrations and which provides protection against
corrosive atmosphere and contamination by chemicals.
The instrument should be protected against excessive temperature fluctua-
tions 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
NOTICE

during the pumping operation. It must be noted that the PVC tubing is
not resistant to solvents.
