Clean seals (O-ring seals)
Leaks with noise generation may occur due to
contamination of the O-rings on the openings to the
casting chamber (for example, due to investment
material residues). Furthermore, vacuum and
pressure values may distort and thus cause the
casting result to be unsuccessful. To remove the O-
ring seals, they can be "ejected" with compressed
air.
1. Open crucible or mould door.
2. Select menu Settings / O-ring seals / Eject O-
ring seals: The O-ring seal is detached with
compressed air.
3. Remove the gasket.
4. O-Ring, Nuten und Dichtflächen mit einem
feuchten Tuch reinigen.
O-Ring sparsam mit Pflegefett (REF 16232)
einfetten.
5. Remove surplus grease with a dry cloth!
6. Do not overstretch the gasket when cleaning
and inserting!
7. Do not interchange the seals, they have differ-
ent sizes! A gasket with a poor fit leads to leak-
age.
8. Repeat the procedure on the second door (cru-
cible or mould door).
Risk of burns due to hot parts!
Carry out maintenance and cleaning
work before casting or only after the
machine has cooled down.
