After every work session, these cleaning steps should be carried out:
1. Bell Cleaning (critical!)
- Carefully remove the bell – avoid damaging the sensitive edges
- Soak in a suitable solvent (according to manufacturer specifications)
- Gently clean with a soft brush – never use metal tools
- Allow to dry completely before reassembly
2. Flush Material System
- Flush the material hose with suitable solvent
- Clean and dry the pressure vessel
- Check all seals for damage
Important: Never clean the bell with sharp objects – this will permanently reduce electrostatic performance!
