▶ To prevent the transmission of structure-borne noise, use elastic elements
to decouple all connecting lines from all vibration-capable components
(e.g. reservoir, frame parts).
▶ Make sure the suction, leakage, and return lines flow into the reservoir below
the minimum fluid level under all operating conditions. This will prevent air
from being drawn in and foam from forming.
▶ When designing the reservoir, ensure that there is adequate distance between
the suction line and the drain line. We recommend using a baffle (baffle plate)
between suction line and drain line. A baffle improves the air separation
ability as it gives the hydraulic fluid more time for desorption. Apart from
that, this prevents the heated return flow from being drawn directly back into
the suction line. The suction port must be supplied with air-free, calmed and
cooled hydraulic fluid.
▶ Make sure that a minimum suction pressure of 0.8 bar absolute is present at
port S (A or B) during operation for all installation positions and installation
locations of the axial piston unit; see Abb. 12. See data sheet for other
pressure values.

Suction conditions are improved with below-reservoir installation and
inside-reservoir installation.
Incorrectly connected suction and pressure lines!
Risk of injury and property damage!
▶ Make sure that the corresponding suction and pressure port is assigned
to the correct direction of rotation. Information on this can be found in
data sheet 91485 and in Tabelle 7 to Tabelle 9 "Flow direction" starting on
page 24.
▶ Make sure that the working environment at the installation site is completely
free of dust and foreign substances. The axial piston unit should be clean when
