your hands.

Notice
The reactor tube filling shown in Abb. 104, Seite 147 is an excellent solution for the
majority of applications.
However, some applications can be optimized by varying the listed default fill. Any de-
viations from the standard filling should be discussed in advance with LAR Technical
Support or with a LAR authorized service partner.
As our research and development progresses, we ask that you stay in touch with your
LAR contact to stay up-to-date with any additions
Danger
Danger of burns
Allow the furnace to cool completely (2 hours in total). One hour after switching off the
furnace, the temperature of the reactor tube is still about 400° C to 500° C!
Always use heat-resistant gloves when working on the furnace.
Warning
Correct installation of removed components
During assembly, remember that all parts that have been removed and / or disassem-
bled must be reassembled as they were in their original condition.
