Online Substitution Pump
OSP (BPV)
The function of the HDF online substitution pump OSP (BPV) can be checked.
Valves
VBE, VDFF, VSB, VSAE, VSAA
The flow path through both filters (DF and HDF) can be set via the valves.
Before operation in main flow the DF filter inlet must be vented via VDFF,
because the membranes of the DF filter and HDF filter are impermeable to air.
Valve VBE can only be opened if PDA < -100 mmHg to prevent fluid
penetration.
