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.
In the wet end of the 909 UV Digester, ozone from the air is released due
to the UV radiation. Set up the instrument in a fume cupboard or closed
laboratory at a location in the laboratory that is suitable for operation and
free of vibrations. The location should be protected from corrosive atmos-
pheres and contamination from chemicals.
The instrument should be protected against excessive temperature fluctu-
ations and direct sunlight.
3.2 Inserting the UV lamp
The UV lamp (6.2804.090) is included in the scope of delivery for the 909
UV Digester.
Caution
Spots on the quartz tube
Spots will be burned into the quartz glass if you touch the UV lamp's
quartz tube with bare hands and put it into operation without cleaning
it first. This lowers the power of the UV lamp.
Always use the cotton glove included with the UV lamp to install the
lamp and only touch the UV lamp at the two flattened ends. Remove
any grease spots or dust particles stuck to the quartz tube before start-
ing the UV lamp.
