7.5 Replacing the Silicone Rubber of the Silicone Holders
To ensure a seal of good quality, the silicone rubber may not be damaged and the surface must be
smooth. Mechanical contact or burning by the sealing wire may damage the rubber.
Replace the silicone rubber if damaged or as specified in Maintenance Schedule on page 24.

1.
2.
Cut a new piece of silicone rubber. Make sure it is the same length as the holder.
If the rubber is too short or too long, this may cause problems with the seal of the
bag.
3.
Install the new piece of silicone rubber by pressing it into the recess of the silicone holder.
Ensure that the silicone rubber is fully and uniformly placed in the recess. It is also important
that the surface of the silicone rubber is smooth after it is in place, and that it shows no signs
of stress.
7.6 Replacing the Lid Gasket
The lid gasket ensures the vacuum chamber is fully closed during the machine cycle. This is
essential to reach the maximum vacuum level. Due to extreme pressure differences, the gasket
wears and should therefore be replaced regularly.
Replace the lid gasket if damaged or as specified in Maintenance Schedule on page 24.
