3. Rinse all threads and clean them with a brush
if necessary.
The shaft and dispersion tool can now be pre-
assembled again, ready for use.
ATTENTION!
Sterilization and disinfection
Wet chemical methods are permissible for steri-
lization and disinfection of the dispersion tools.
Many instances of disinfection can be solved by
means of bactericidal solutions. It is important
that the remains of the disinfectant are subse-
quently removed with sterilized water.
No moisture must be allowed to enter the ball
bearing, so, basically, the upper end of the
shaft tube must be sealed (e.g. with silicone

plugs).
Other sterilization methods (e.g. moist heat
120 °C at 2 bar, or killing the bacteria with
hot air at 160 °C to 190 °C) are not allowed.
Maintenance
The correct functioning of the generator essenti-
ally depends on the sharpness of the edges of the
tooth crests on the rotor and stator. The edges
can wear with abrasive media, reducing the ef-
fectiveness of the dispersion.

Repair
In case of repair the device has to be cleaned and
free from any materials which may constitute a
health hazard.
If you require servicing, return the appliance in
its original packaging. Storage packaging is not
suffi cient. Please also use suitable transport pa-
ckaging.
Changing the slide ring seal
To prevent damage to the unit, the slide ring
seal must only be changed by a skilled me-
chanical person.
Change the slide ring seal as follows:
1. Slacken off the three grubs crews (D) and pull
the drive shaft downwards until the counter-
ring (F) becomes free. The lower part of the
slide ring seal (E) can then be easily removed.
2. To dismount the drive shaft, it may be neces-
sary to remove the upper retaining ring (G)
using retaining ring pliers, particularly where
there is heavy soiling. To avoid any damage,
do not strike the drive shaft.
3. When refi tting, adjust the bearing pressure of
the two sealing surfaces. The correct bearing
pressure is obtained when the lower part of
the slide ring seal (E) is inserted far enough
– before being secured - so that it is aligned
with the upper external part (F).
