5.3 Restarting the analyzer after an emergency shutdown
WARNING
Concentrated sulfuric acid can cause severe chemical burns! Wear protective clothing
when working at the sulfuric acid container and the gas transfer line! Observe all
specifications in the safety data sheet!
If the multi X 2500 is operated with an optional multi-purpose combustion tube, there
may be residual sulfuric acid in the gas transfer line after an emergency shutdown.
Take particular care when checking the gas transfer line!
Observe the following instructions when putting the analyzer back into service:
1.
Remove the gas transfer line from the sulfuric acid container in the chlorine
module and drain the sulfuric acid from the sulfuric acid container (
→
"Changing
the sulfuric acid and cleaning the sulfuric acid container with outlet", p. 101).
2. Disconnect the gas transfer line inside the basic device from the auto-protection
assembly and remove the connector of the heating cable from the socket.
3. Carefully remove the gas transfer line from the basic device and check it for
contamination with sulfuric acid.
4. If necessary, clean the gas transfer line:
Rinse the gas transfer line with distilled water and then with ethanol.
Dry the gas transfer line (e.g. by blowing it through with an inert gas).
5. Refit the gas transfer line:
To do this, connect the gas transfer line to the auto-protection assembly and plug
the connector of the heating cable into the socket.
Route the gas transfer line through the side panel to the chlorine module and
connect it to the sulfuric acid container with outlet (
→
"Preparing the chlorine
module", p. 68).
6. Refill the sulfuric acid container with sulfuric acid.
