Dirty O-rings on the openings to the casting
chamber (e.g. residual investment material) may
lead to leaks that would create some noise.
Moreover, the vacuum and pressure values may
change, which could lead to faulty casting results.
O-rings can be ejected with compressed air.
WARNING
Burn hazard from hot parts!
Carry out maintenance and cleaning
work before casting or after the device
has cooled down.
1. Open the mould flap.
2. Go to Settings > O-rings > Eject O-rings (1).
The O-ring will be released with compressed
air.
3. Remove the O-ring.
4. Clean the O-ring, grooves and sealing sur-
faces with a cloth and isopropyl alcohol.
5. Slightly grease the O-rings with seal grease
(REF 16232).
CAUTION
The grease is difficult to remove
from skin and clothing.
Wear the protective clothing and
gloves prescribed for use in dental
laboratories!
6. Remove surplus grease with a dry cloth!
7. Insert the seal again
NOTICE
• Do not overstretch the seal when cleaning and
inserting!
• Do not interchange the seals, they have differ-
ent sizes! A seal with a poor fit leads to leak-
age.
8. Repeat the process with the crucible flap.
9. Check the seals, see page 75.
