7. Connect right drying flask to the gas connection of the Oven "From drying flask" using
6.1805.080 Tubing.
8. Set 6.2724.010 Dust filter onto the connection "Purge" of the Oven and set 6.1808.130
Adapter onto dust filter. Connect this adapter with the left outlet of the insert tube using
6.1805.180 tubing.
9. Set up the tubing connection "To Oven" to the right inlet of the insert tube with another
6.1805.180 Tubing.
10. At the rear of the oven, connect the two tubing connections "Air in" and "Air out" using
the 6.1805.040 Tubing.
When working with a gas other than air, this tubing connection is removed. The gas is
introduced at tubing connection "Air/N
2
in" using a 6.1808.020 Tubing Connector. Tubing
of 3...4 mm internal diameter can be attached to the tubing connector.
11. Plug the 6.2724.010 Dust Filter into the "Filter" connection at the rear of the oven.
11. Screw the 6.1805.070 Outlet Tubing to the insert tube and route other end to the titration
vessel, see pages 47ff.
Important: Never wind insulation material around the outlet tubing when working at high
sample temperatures as the connection could melt. To avoid condensation in the outlet
tubing, the 6.1830.000 Heatable Outlet Tubing can be used.
If the filter on the Oven is blocked, you may remove the filter as well as the 6.1808.140
adapter and connect the tubing directly to the Oven. Order a new 6.2724.010 filter immedi-
ately to avoid blocking of the built-in pump.
