Connecting the leak connection
Fig. 11: Leak connection
The following instructions have to be adhered to:
The leak has to be discharged in a fully
depressurised state.
n
If there are several leak connections, all leak
connections must be connected individually.
The same requirements apply to all leak con-
nections.
n
Standard devices are not suitable for leak
extraction. It is imperative that you consult the
manufacturer to establish the necessary addi-
tional measures.
n
The leakage line must be dimensioned so that
the leakage rate can be recorded (see test
report).
Lay the leak line with a downward slope so
that the medium can drain off without back-
Ball bearings and components must be
covered with the working medium. This
prevents dry-running.
6.4.3.5
Install the device vertically
When installed vertically the internal arrangement
of the components ensures adequate lubrication of
the bearings. Special measures are not required.

6.4.4 Installing the cartridge elements
(Rotostat A and N only)
6.4.4.1
Mounting or installing the unit
1.
Ensure that the borings in the shafts don't
lead to imbalance.
2.
NOTICE!
Component damages from faulty
installation!
Ensure that the cartridge elements are not
jammed.
3.
Ensure that the components are free of dirt.
4.
Brush the boring and the shaft with oil-
soluble grease or viscous oil.
5.
If possible, insert the cartridge element first
into the boring and then fasten axial.
6.
Small installation size (up to Rotostat 80
A / Rotostat 80 N):
Insert shaft manually.
Starting at installation size Rotostat 100
A / Rotostat 140 N:
Insert the shaft and using the plastic
hammer and slight blows on the circumfer-
ence, or press them in with a mounting
device.
