7.3.2 Above-reservoir installation
Above-reservoir installation means the axial piston unit is installed above the
minimum fluid level of the reservoir.
Also bleed air through air bleed port R when installing with the "drive shaft upwards"
(special version).
Recommendation for installation position (drive shaft upward): A check valve in the
drain line (cracking pressure 0.5 bar) can prevent the housing area from draining.
