Notes on safety

•
This centrifuge is a state-of-the-art piece of equipment which is extremely safe to operate.
− However, it can lead to danger for users or others if used by untrained staff, in an inappropriate way or for a
purpose other than that it was designed for.
•
Before the initial operation of your centrifuge you should read and pay attention to the operating instructions.
•
Along with the operating instructions and the legal regulations on accident prevention, you should also follow the
recognised professional regulations for working in a safe and professional manner.
These operating instructions should be read in conjunction with any other instructions concerning accident
prevention and environmental protection based on the national regulations of the country where the device is to
be used.
•
The centrifuge should be installed on a good, stable base.
•
The centrifuge must not be moved or knocked during operation.
•
To avoid damage due to condensate, when changing from a cold to a warm room the centrifuge must either run
hot in the cold room for 30 minutes, or warm up for 3 hours in the warm room, before connecting to the mains.
•
Centrifuge containers must not be filled beyond the capacity specified by the manufacturer.
− Centrifuge containers should only be filled outside the centrifuge.
•
Standard centrifuge containers of glass will not stand RCF values exceeding 4000 (DIN 58970, pg. 2)
•
Centrifuge containers may only be centrifuged with accessories (reducing adapters, frames, suspensions, etc.)
authorised by the manufacturer (see section "Anhang/Appendix, Rotoren und Zubehör/Rotors and accessories").
•
When centrifuging with maxim revolutions per minute the density of the materials or the material mixtures may not
3
exceed 1.2 kg/dm .
•
The centrifuge may only be operated when the balance is within the bounds of acceptability.
•
The centrifuge must not be operated in areas subject to danger of explosions.
•
The centrifuge must not be used with:
− inflammable or explosive materials
− materials that react with one another producing a lot of energy.
•
If users have to centrifuge hazardous materials or compounds contaminated with toxic, radioactive or pathogenic
micro-organisms, they must take appropriate measures.
Without additional proceedings (like an additional bioseal between bucket and lid of bucket or angle rotor with a
special bioseal between rotor and lid) a centrifuge is not a biosafety system in accordance to the regulation EN
61010-2-20. In the case of material belonging to risk group II (see the World Health Organisation's "Laboratory
Biosafety Manual") they should employ a biosafety system. Under this system small drips and aerosols are
prevented from escaping by a bioseal (packing ring) located between the hanger and the lid. Centrifuge
containers with special screw caps, as obtainable through trade suppliers, can also be used for hazardous
substances.
In the case of materials from the higher risk groups greater safety provision is required than the arrangements
described above. In a biosafety system, centrifuge containers with special screw caps must be used.
•
For further details of available biosafety systems see section "Anhang/Appendix, Rotoren und Zubehör/Rotors
and accessories". If in doubt, you should obtain relevant information from the manufacturer.
•
The centrifuge must not be operated with highly corrosive substances which could impair the mechanical integrity
of rotors, hangers and accessories.
•
Any rotors, hangers or accessories showing clear signs of corrosion or mechanical defects must not be used for
centrifuging.
•
Repairs must only be carried out by personnel authorised to do so by the manufacturer.
•
Only original spare parts and original accessories licensed by the Hettich company are allowed to be utilised.
•
In case of fault or emergency release, never touch the rotor before it has stopped turning.
•
This centrifuge is classified in Germany as a Group 3 device according to the Medizinische Geräteverordnung
MedGV (the regulations on medical equipment).
•
It conforms to safety regulations based on:
IEC 1010-1/-2
DIN - EN61010 Parts 1and 2
•
The safe operation and reliability of the centrifuge can only be guaranteed if:
− the centrifuge is operated in accordance with the operating instructions,
− the electrical installation on the site where the centrifuge is installed conforms to the demands of IEC
stipulations,
− prescribed tests to UVV-VBG7z are carried out by an expert.
•
With centrifuges for robotic use please pay attention to the notes of the key operated switch.
No claim under guarantee will be considered by the manufacturer unless the above instructions have been
adhered to.
