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
and/or
L
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 34.
Axial piston units with electric components (e.g. electric controls, sensors)
must not be installed in a reservoir below the fluid level.
We recommend fitting a suction pipe to the suction port
S
and fitting a pipe to
the drain port

. In this case,
the other leakage ports must be plugged. The housing of the axial piston unit
must be filled before fitting the piping and filling the reservoir with hydraulic fluid.
To prevent draining of the housing, the reservoir has to be filled with
hydraulic fluid as quickly as possible.
