7.4.12 Hydraulic connections

When using (thick wall) piping and in applications with frequent reversal of
rotation direction, it is recommended to fit flexible hoses between the motor and
piping to avoid damage due to vibration and to simplify installation of the motor. The
length of the hoses should be kept as short as possible.
