Proceed as follows to replace the filling in the inlet gas
purification (see Pos. (2) in “Removing the reagent tubes
on filters”):
1. Turn the main switch on the analyzer to Position 1.
2. Remove the reagent tube, see “Removing the reagent
tubes on filters”.
3. Remove the used filling from the reagent tube.
4. Dispose of the reagent tube filling in accordance with
local regulations and provisions.
5. Ensure that the reagent tube is undamaged.
If it is damaged or too contaminated, use a new
reagent tube (Part No. 88400-0006).
6. Fill the reagent tube with 1.5 to 2 cm of glass wool
(Part No. 90331).
7. Fill approx. 10 cm of magnesium perchlorate (Part No.
90200) onto the glass wool.
8. Fill 0.5 to 1 cm of glass wool (Part No. 90331) onto the
magnesium perchlorate.
9. Fill approx. 10 cm of sodium hydroxide (Part No.
90210) onto the glass wool.
10. Fill 1.5 to 2 cm of glass wool (Part No. 90331) onto the
sodium hydroxide.
11. Insert the filled reagent tube, see “Inserting the
reagent tubes on filters”.
The inlet gas purification filling has been replaced.
