7.3.3 Above-reservoir installation
Above-reservoir installation means that the axial piston unit is installed above
the minimum fluid level of the reservoir.
Observe the maximum permissible suction height h
S max
= 800 mm. The
permissible suction height h
S
is derived from the total pressure loss.
Because complete air bleeding and filling are not possible in installation
positions 16 and 17, the axial piston unit should be air bled and filled in a
horizontal position before installation.
To prevent the axial piston unit from draining, a height difference h
ES min
of at least
25 mm at port
F
is required in installation position 14 and 15.
