9.7 Replacing the Door Bellows (Located in the door bridge)
The door bellows is designed to work with the closing device
providing a double lock that keeps the door closed while there is
pressure inside the chamber.
Caution!
Before starting, disconnect the instrument from the power source
and ensure that there is no pressure in the autoclave’s chamber.
1. Open the door.
2. Unscrew and remove the locking bolt (5).
3. Remove the Bellows assembly, using one of these two methods
3.1 Blow compressed air into the steam inlet hole on the inner
surface of the door. This will cause the Bellows Assembly to
pop out.
3.2 Gently pull out the door safety device locking pin (13). And
using a bellows extraction tool, remove the bellows assembly.
4. It is possible that the washers (7, 10) will be stuck - if so, again use
compressed air to blow them out or the bellow extraction tool to
remove them.
5. Insert a new Door Bellows Kit (13,12,10,7) into the original brass
sleeve (14), making sure to insert the kit into the narrower end of
the sleeve. (No lubrication or cleaning is required.)
6. Insert the locking bolt (5) into the sleeve, making sure that the
collar on the bolt fits into the sleeve.
7. Reinstall the completed assembly into the door bridge.
8. Tighten the locking bolt (5), it need not be super tight, just tight
enough to properly seat the rear washer (7).
9. Run a test cycle and check for leaking.
