Translation of the original operating manual

• Replace any damaged components immediately for your own safety.
• Immediately rinse off the rotors or accessories if any liquids that may

cause corrosion come into contact with them.

• Clean the accessories outside the rotational vacuum concentrator once

a week or preferably after each use.

• If the rotors or accessories have been contaminated with toxic,

radioactive, or pathogenic substances, clean them immediately with a
suitable decontamination agent (depending on the type of
contamination). Take suitable precautions for your own safety if there is
a risk of toxic, radioactive, or pathogenic contamination.

8.1.4.1 Aluminium accessories

Especially aluminium parts are susceptible to corrosion.
• Acid-containing cleaning agents and alkaline cleaning agents must be

avoided.

• Grease aluminium parts at least once a week with slushing oil for the

protection against corrosion.

This essentially increases their service life and reduces susceptibility to
corrosion.

8.1.5 Glass breakage

CAUTION

In the case of glass breakage, immediately remove all glass particles (e.g.
with a vacuum cleaner). Replace the rubber cushions since even thorough
cleaning will not remove all glass particles.

Glass particles will damage the surface coating (e.g. anodising) of the
buckets, which will then lead to corrosion.
Glass particles in the rubber cushions of the buckets will cause glass
breakage again.
Glass particles on the pivot bearing of the load- bearing bolts prevent the
buckets and rotor blocks from swinging evenly, which will cause an
imbalance.
Glass particles in the rotor chamber will cause metal abrasion due to the
circulation. This metal dust will not only pollute the rotor chamber, rotor,
and materials to be evaporated but also damage the surfaces of the
accessories, rotors, and rotor chamber.

In order to completely remove the glass particles and metal dust from
the rotor chamber
• Grease the upper third of the rotor chamber with e.g. Vaseline.
• Then, let the rotor rotate for a few minutes at maximum speed and

atmospheric pressure. The glass and metal particles will now collect at
the greased part.

• Remove the grease with the glass and metal particles with a cloth.
• If necessary, repeat this procedure.
• Clean the rotor shaft.
