5.2 Maintenance
After every 1000 cycles or two years, a reminder message appears
to perform maintenance.
The maintenance must only be carried out by an
authorised and qualified service technician.
The maintenance consists of replacing, cleaning and
checking some parts, as indicated in the relative table.
The work consists of the following:
Replace:
- door seal
- bacterial or Bio X filter
- chamber filter
- water filter
Check:
- Safety valve check
- Leakage current check
- Hose checks: hoses performance does not change until they
physically break, in which
case they do not work. Only replace them with DÜRR DENTAL
spare parts.
When finished, the qualified technician will issue a certificate stating
that the autoclave maintenance was carried out.
Comply with the intervals specified or indicated in this manual and
in the additional sheets. Only use ORIGINAL SPARE PARTS. Failure
