8 Servicing and maintenance
These maintenance instructions are intended to answer questions on care and maintenance in a
clearly laid out form.
If servicing is not performed correctly, the guarantee is void for damage to the product caused by
incorrect maintenance.
In this case there is also no liability for damage caused by the product.
Important note to the service life of your device:
Our devices are mostly free of maintenance. But even if you ensure regular maintenance
and care, some of the built-in components will reach the end of their operational life (e.g.
elastomer parts). Therefore, after 10 years our devices reach the end of their service life,
under bad conditions earlier. We strongly recommend to send in your device to WITT Ser-
vice for checking and control at least 8 weeks before this time period has expired.
Witt Gasetechnik then also will check, if your device does met actual technical needs (state
of the art).
In cooperation with you we can actualise your device to the state of the art.
Any provided manuals from component manufacturers have to be regarded too, especially
maintenance or replacement intervals.
Maintenance intervals depend very much on individual operating conditions. The intervals
shall be considered as starting values which should be shortened or extended as appropri-
ate.
