▶ When designing the reservoir, ensure that there isanadequate distance between
the suction line and the drain line. This prevents the heated return flow from
being drawn directly back into the suction line.
▶ Make sure that aminimum suction pressure of0.8bar abs. (without charge
pump) or0.7bar abs. (with charge pump) ispresent atport "S" during operation
and atcold start, inall installation positions and installation locations for the
axial piston pump, see Fig. 8. See data sheet for other pressure values.

The suction conditions improve with installation below and inside the reservoir.
▶ 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
installed. Contamination ofthehydraulic fluid can considerably affect the
function and service life oftheaxial piston unit.
▶ Use fiber-free cleaning cloths for cleaning.
▶ Use suitable, mild cleaning agents toremove lubricants and other heavy
contamination. Do not allow cleaning agents toenter into the hydraulic system.
