Preparing for return
1. Flush the vacuum system with air for a few minutes (if
necessary for safety reasons: with inert gas) at atmo-
spheric pressure to free the pump head of dangerous or
aggressive gases (see Chapter 10.2.1 Flush vacuum sys-
tem [} 53]).
Please contact your KNF sales partner if the vacuum
system cannot be flushed due to damage.
2. Remove the vacuum system.
3. Clean the vacuum system (see Chapter 10.2.2 Clean vac-
uum system [} 54]).
4. Send the vacuum system together with the completed
Health and Safety Clearance and Decontamination Form
to KNF, stating the nature of the transferred medium.
5. Pack the device securely to prevent further damage to the
product. If necessary, request original packaging for a fee.
