ThismanualdescribespossibilitiestodecontaminatetheaspirationsystemsBVC
andthehandleVHCpro.
Priortodecontaminationcleanwithadampclothifnecessary.Usewateroramild
detergent as cleaning agent.
Prior to sending the devices to the factory the devices have to be decontami-
anted completely.
The applicability of the decontamination method and the selection of the ap-
propriate disinfectants have to be ensured by the user.
Ensure that repair is done only by an appropriately trained and supervised tech-
nician.Obeylocalandnationalsafetyrequirements.Ensurethatthetechnicianis
familiar with the safety procedures which relate to the products processed by the
pumpingsystem.Ensure that the pumpis decontaminated before repair andthat
youtakeadequateprecautionstoprotectpeoplefromtheeffectsofhazardoussub-
stances if contamination has occurred.
+Take adequate precautions to protect people from the effects of dangerous sub-
stances. Wear appropriate safety-clothing, do not inhale and avoid contact with
skin.
Prior to decontamination from outside and / or disassembling the device isolate
equipment from mains. Allowsufcientcooling.
Ensure that the device cannot be operated accidentally. Never operate the de-
vice if covers or other parts are disassembled. Never operate a defective or
damaged device.
Wait 5 seconds before starting work to allow the capacitors to discharge.
Beforestartingcheckthattherequiredparts(e.g.tools,disinfectnats)areavailable
and of the correct type.
Checktheoperatingsequencementallyusingexplodedviewdrawings,spareparts
lists and circuit diagram on feasibility, safety requirements and consequences on
safetyandfunctionoftheequipment.
Obeyregulationswhendisposingofsolventsandchemicals.
Inorder tocomplywithlaw(occupational,healthandsafetyregulations,safetyat
worklawandregulationsforenvironmentalprotection)vacuumpumps,components
and measuring instruments returned to the manufacturer can be repaired only when
certainprocedures(seesection”Notes on return to the factory”)arefollowed.
Scrapping and waste disposal
Dispose of the pump and any components removed from it safely in accordance with
alllocalandnationalsafetyandenvironmentalrequirements.

Important notes on use of disinfectants
Aggressivedisinfectantswhichreleasechlorineoroxygenrad-
icals,e.g., sodium hypochlorite(chlorinebleach) or peroxide
compounds can corrode the material of the 4l polypropylene
collectionbottleandothercomponents(e.g.,couplings).This
may lead to stress cracks and breakage of the 4l polypropyl-
ene bottle.
+Therefore, prolonged use of these disinfectants in the 4l
polypropylene bottle is strongly discouraged. After brief
disinfecting operations in the bottle, rinse bottle thoroughly
to avoid leaving residues of disinfectant in the bottle.
➨ Alternative:UsetheBVCcontrolG/BVCprofessionalG
with 2l borosilicate glass bottle.
 Attention:Thequick-couplingaccessorysetsbetweenthe
pumpingunitandVHCpro are not suitable for use with chlo-
rine bleach.
