*
1)
Observe the permissible flow rate in the pressure pipe: 0.7 to 2.3 m/s according to EN 12056
*
2)
Improper unit and pipe installation, as well as impermissible operation, can increase the acoustic emissions.
*
3)
Measured in relation to installation level
*
4)
The current peak flow must always be lower than the volume flow of a pump at the duty point
