7.3.2 Above-reservoir installation
Above-reservoir installation means that the axial piston unit is installed above the
min. fluid level of the reservoir.
Also be sure to bleed air through air bleed port R when installing with the drive
shaft up (special version).
Do not install the A2FE and A2FMT with the drive shaft up.
Recommendation for installation position 8 (drive shaft up): A check valve in the
drain line (cracking pressure 0.5 bar) can prevent the housing area from draining.
