4.1 Replacing the sealing wire and Teflon tape
Remove the sealing bar from the chamber.
Remove the damaged Teflon tape from the seal bar.
Unlock and remove the two (M6) grub screws (that retain the seal wire) from the underside of the seal
bar using a 4mm-hexagon key.
Remove the damaged seal wire.
Carefully clean the sealing bar.
4.2 Replacing the sealing wires
1. Ensure that the two tension spring and screw assembly are in place in either end of the seal bar.
2. Fold over 50mm of the end of the new seal wire, push this end into the slot (underneath the seal
bar) so that it extends beyond the (hole) position where the electrical pin contacts in the chamber
fit. Clamp this end of the wire into place with the (M6) grub screw.
3. Run the remaining length of the wire along the top of the bar, fold over the end and fit similarly at
this opposite end as the first, ensure that both (M6) grub screws are tightly secured.
4.3 Replacing the Teflon tape
Remove the protective paper backing strip (from the new Teflon tape strip) and stick the tape onto the
bar. Ensure that the tape overlaps the ends of the seal bar.
4.4 Reinstalling a new sealing bar
Put the repaired sealing bar back into the chamber over the plug pins. On machines with the sealing
bar in the lid the contact points must be reconnected.
4.5 Replacing the silicone in the counter bar
Pull the silicone strip out of the groove, clean the groove and fit the new strip.
4.6 Maintenance of the silicone gasket in the lid
Clean the silicone gasket with a damp cloth. Never use synthetic cleaning agents. If the gasket is
damaged replace immediately as this will reduce the efficiency of the machine.
4.7 Replacing silicone gasket in the lid
Remove the damaged gasket. Cut a length of new silicone gasket to match the old strip clean the
groove and press the new gasket into place. Make sure the ends of the strip are pressed evenly
together. No leakage should occur!
