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.
