- Seal inspection

- Checking the condition of the hoses
Make sure that connecting hose hoses "A" is in a good
condition and correctly fixed.
If the hose is damaged, broken or badly connected to
the unions, this must be replaced.
When sticky materials are treated, check for possible
clogging along the hose, in outlet and on the baffle in
the filtering chamber.
Scrape outside the outlet and remove the deposited waste
as indicated in fig. 14.
- Checking the lid seal
If seal "A" under head "D" has become slack, unscrew
screws "B" that lock fastening latches "C" in place and allow
them to slide downwards until lid "D" closes perfectly.
Now tighten locking screws"B".
Replace seal "A" - fig. 15 - if an optimum seal cannot be
obtained.
- Checking the tightness of filter chamber
If seal "A" - fig. 16 - between the container and filter
chamber "C" fails to guarantee tightness:
- loosen the four screws "B" that lock filter chamber "C"
against vacuum structure.
- Allow filter chamber "C" to lower down and relock screws
"B" once it has reached the retention position.
The seal must be replaced if it is torn, cut, etc.
Replace seal "A" if the degree of tightness is still not
optimum.
