Bosch Rexroth A10VSNO Instruction Manual page 29

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 30.
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 case
drain port L or L . In this case, the other drain port must be plugged. The housing
1
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 is not
possible in installation position 5, the axial piston unit should be air bled and
filled in a horizontal position prior to installation.
