Inside-reservoir installation is when the axial piston unit is installed in the reservoir
below the minimum fluid level. The axial piston unit is completely below the
hydraulic fluid.
If the minimum fluid level is equal to or below the upper edge of the pump,
see chapter 7.3.3 "Above-reservoir installation" on page 29.
Axial piston units with electric components (e.g. electric controls, sensors)
must not be installed in a reservoir below the fluid level.
Our advice is to fit a suction pipe to the suction port S and to fit a pipe to the
drain port l, l or l . In this case, the other drain port must be plugged. The case

of the axial piston unit must be filled before fitting the piping and filling the
reservoir with hydraulic fluid. Because complete air bleeding and filling are not
possible in installation positions 6 and 8, the axial piston unit should be air bled
and filled in a horizontal position prior to installation.
