With the attached Voith pressure limiting valve, the plug screw (MP) can be bled.
When activating the electric motor, open the MP pipe of the pump stage valve.
After the bleeding process is complete, seal the pipe again.

10.5 Commissioning the pump
After the bleeding process, the pump should remain depressurized until the system
is fully bled. Then load the pump with the projected pressure, and secure the
pressure limiting valve so that it cannot be adjusted.
The system is sufficiently bled when there are no jarring noises and there is no foam
build-up in the return line to the tank.
If there is no pressure build-up for approx. 30 to 60 seconds (< 2 bar circulating
pressure), switch off the motor and check the direction of rotation!
