Preparing for return
1. Flush the pump with air for a few minutes (if necessary for
safety reasons: with inert gas) at atmospheric pressure to

Please contact your KNF sales partner if the pump can-
not be flushed due to damage.
2. Remove the pump.
3. Clean the pump (see Chapter 9.2.2 Cleaning the pump
[} 29]).
4. Send the pump together with the completed Health and
Safety Clearance and Decontamination Form to KNF,
stating the nature of the transferred medium.

product. If necessary, request original packaging for a fee.
