7.3.2 Inside-reservoir installation
Inside-reservoir installation is when the axial piston unit is installed in the tank
below the minimum hydraulic fluid level. The axial piston unit iscompletely below
thehydraulic fluid.
Iftheminimum fluid level isequal toor below theupper edge ofthepump,
seechapter7.3.3 "Above-reservoir installation".
Our advice is to fit a suction pipe to the suction port "S" and to fit a pipe to case
drain port "R(L)" or "T". In this case, the other ports must be plugged, except the
bearing flushing "U" for installation position "drive shaft up". The housing
oftheaxial piston unit must befilled before fitting thepiping and filling
thereservoir with hydraulic fluid.
