9.1 Flushing the pump
When transferring dangerous and environmentally hazardous media, KNF
recommends flushing the pump at atmospheric pressure for a few minutes
prior to switch-off (if necessary for safety reasons: with an inert gas) to ex-
tend the service life of the diaphragm.

Discharge the media safely.
