3. Remove the white insulation

which now becomes visible (see

Fig. 2-83). The cover of the py-

rolysis unit becomes visible as

well.

4. Loosen the nuts on the granu-

late container (see

Fig. 2-84) and lift it out along

with the granulate (see

Fig. 2-85). It must be assured

that the nuts and the washers

do not fall into the pipe connec-

tion.

5. Remove the screws which se-

cure the grate and lift the grate

and Gauze Filter off (see Fig. 2-

86).

6. Inspect the granulate for con-

tamination by breaking open

several pellets. If the granulate

is dark colored all the way

through, it has become saturat-

ed and must be replaced.

7. Fill the container with new gran-

ulate under dust-free condi-

tions.

8. Apply copper paste to the

threads. Copper paste is heat-

resistant up to 1000° C.

If the old nuts need are no lon-

ger usable, do not replace them

with stainless steel or zinc plat-

ed nuts.

9. Reinstall the granulate contain-

er by following the above in-

structions in reverse order,

insert the insulation and the

seals (or replace if damaged)

and secure the cover with the

screws.
