▶ When designing the reservoir, ensure that there isanadequate 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 aminimum suction pressure of0.8bar abs. (without charge
pump) or0.7bar abs. (with charge pump) ispresent atport "S" during operation
and atcold start, inall 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 attheinstallation site iscompletely
free ofdust and foreign substances. The axial piston unit should beclean when
installed. Contamination ofthehydraulic fluid can considerably affect the
function and service life oftheaxial piston unit.
▶ Use fiber-free cleaning cloths for cleaning.
▶ Use suitable, mild cleaning agents toremove lubricants and other heavy
contamination. Do not allow cleaning agents toenter into the hydraulic system.
