Preparing the analyzer (optional variant)
The preparation of the analyzer includes the following steps:
Installing the auto-protection assembly and the gas transfer line
Inserting the multi-purpose combustion tube
Prepare the chlorine module
Refer to chapter "AOX determination in horizontal operating mode", p. 65 for
information on the installation of the auto-protection assembly and the gas transfer
line.
Inserting the multi-purpose combustion tube:
The following section describes how the multi-purpose combustion tube is inserted in
horizontal and vertical operating mode.
WARNING
Danger of explosion! The hose connections for argon and oxygen on the combustion
tube must not be mixed up.
CAUTION
Risk of burns! Only install the combustion tube in the cold state!
NOTICE
Alkaline salts (hand perspiration) cause crystallizations in the quartz glass when
heating the combustion furnace which reduce the service life of the combustion tube.
Where possible do not touch the combustions tube with your hands during
installation. Wear protective gloves. If necessary, clean the combustion tube externally
before installing it in the combustion furnace (e.g. by wiping it with moist cellulose).
1.
Make sure that the analyzer is switched off. Switch off the gas supply.
2.
In vertical operating mode, remove the cover at the top. In horizontal operating
mode, open the service flap on the right-hand side.
3.
Insert the combustion tube into the combustion furnace. When doing this, make
sure that the connections on the combustion tube fit into the recesses on the
furnace.
