Above-reservoir installation

Above-reservoir installation means that the axial piston unit is installed above the
minimum fluid level of the reservoir.
To prevent the axial piston unit from draining, a height difference h
25 mm at port F is required in installation position 10.
Observe the maximum permissible suction height h
permissible suction height h
Because complete air bleeding and filling are not possible in installation positions
10 and 12, the axial piston unit should be air bled and filled in a horizontal
position before installation.
