Please note that the cartridge or syringe has to be filled up always with
sufficient sealing liquid to avoid air or moisture contact.
In case of installation within explosion proof areas a level control for the
reservoir of the seal liquid is necessary to avoid dry running of the pump.
If the fluidic seal module is empty the pump must shut down immediately.
If a different installation is selected than the standard installation (e.g. pump
marking horizontal readable) it is possible to exchange the seal liquid inlet port
and outlet port.
The cartridge always has to be assembled in a vertical way to guarantee that
the liquid is gas free and can refill the sealing chamber.
