NOTICE
When performing maintenance or care work, always wear appropriate protective gloves.
In particular, do not touch components directly involved in the analysis process (hook,
sluice, ABD connection piece, ...) with your bare hands. Touching these components with
your bare hands can result in problems with blank values (especially during nitrogen de-
termination).

Ensure that all connections are gas-tight again after servicing:
¡
Tighten the finger-tight screw connection (hose 16) finger-tight!
¡
Ensure that the screw connections are not skewed!
¡
Ensure that the ABD connection piece is installed correctly!
¡
Check the system for tightness
(see user manual of the analyzer).
