Use according to specification
The machine on hand is a centrifuge that is exclusively conceived for the separation of substances or respectively
substance mixtures with a density of max. 1.2 kg/dm³ and which is therefore only designated for this application. A
different use or application over and above this is deemed not in accordance with the specifications. The company
Andreas Hettich GmbH & Co. KG undertakes no liability for damages resulting therefrom.
Belonging to the application according to specification is also the observance of all references contained in the
Instruction Manual and compliance with the inspection and maintenance works.
2 Residual
risks
The machine is constructed according to the state of the art and the recognized technical safety regulations. However
during your application of the device hazards towards life and limb of the user or third parties or respectively
impairments to the device or other material assets can arise. The machine is only to be used for the specified
applications and only in an impeccable technical safety condition.
Disturbances that can interfere with the safety are to be immediately rectified.

Notes on safety
•
Before the initial operation of your centrifuge you should read and pay attention to the operating
instructions.
Only personnel that has read and understood the operating instructions are allowed to operate the
device.
•
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.
•
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.
•
The centrifuge should be installed on a good, stable base.
•
Before using the centrifuge absolutely check the rotor for firm placement.
•
Ensure that no persons and / or dangerous materials are located within a safety zone of 300 mm around the
equipment when a centrifuge is running.
•
The centrifuge must not be moved or knocked during operation.
•
In case of fault or emergency release, never touch the rotor before it has stopped turning.
•
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.
•
Load centrifuge rotor evenly. All positions on rotor must be filled.
•
Do not fill centrifuge containers inside the centrifuge.
•
Centrifuge containers must not be filled beyond the capacity specified by the manufacturer.
•
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
exceed 1.2 kg/dm
3
.
•
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
61010-2-020. 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.
