7.3.2 Inside-reservoir installation
NOTICE
Risk of damage with inside-reservoir installation!
To prevent damage to the axial piston unit, all plastic parts (e.g. protective plugs,
covers), except for the tamper-proof caps, must be removed prior to installation
in the reservoir.
▶
Remove all plastic parts, except for the tamper-proof caps, before you install the
axial piston unit in the reservoir. Make sure that no parts of them remain in the
reservoir.
▶
Remove the protective plug from the suction port
S
and open at least one
T
port.
Inside-reservoir installation is when the axial piston unit is installed in the reservoir
below the minimum 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" on page 30.
Axial piston units with electric components (e.g. electric controls, sensors) must
not be installed in a reservoir below the fluid level. Exception: Installation
of the axial piston unit with E2 /E6 control. However only with Hirschmann
connector and if mineral hydraulic fluids are used and the fluid temperature in the
reservoir does not exceed 80 °C.
Our advice is to fit a suction pipe to the suction port
S
and to fit a pipe to drain
port
T
1
or
T
2
to encase. In this case, the other drain port must be plugged. The
housing of the axial piston unit must be filled before fitting the piping and filling
the reservoir with hydraulic fluid.
