Notes on safety

No claim under guarantee will be considered by the manufacturer unless the above instructions have
been adhered to.
•
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.
•
When the centrifuge is running, according to IEC 61010-2-020, no persons, dangerous substances or objects may
be within the safety margin of 300 mm around the centrifuge.
•
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 heat
up for at least 3 hours in the warm room before being connected to the mains, or run hot for 30 minutes in the
cold room.
•
Only the rotors and accessories approved by the manufacturer for this device may be used (see chapter
"Anhang/Appendix, Rotoren und Zubehör/Rotors and accessories").
•
The centrifuge rotor may only be loaded in accordance with the chapter "Loading the rotor".
•
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 may not be operated in explosion-endangered areas.
•
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.
For hazardous substances centrifuge containers with special screw caps must strictly be used. In addition to the
screw cap centrifuge containers, for materials in hazard category 3 and 4 a biosafety system must be used (see
the World Health Organisation's "Laboratory Biosafety Manual").
Under a biosafety system small drips and aerosols are prevented from escaping by a bioseal (packing ring)
located between the hanger and the lid.
If the hanger of a biosafety system is used without the lid, the packing ring must be removed from the hanger in
order to prevent the packing ring from being damaged during the centrifugation run. Damaged packing rings must
not be used to seal the biosafety system.
Without the use of a biosafety system the centrifuge is not microbiologically sealed in the sense of the EN
610101-2-020 standard.
For further details of available biosafety systems see chapter "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.
•
Rotors, suspensions and accessories that possess traces of corrosion or mechanical damage or if their term of
use has expired may not be used any longer.
•
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 Andreas Hettich GmbH & Co. KG company are
allowed to be utilised.
•
The following safety regulations apply:
IEC 61010-1 and IEC 61010-2-020 as well as their national deviations.
•
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 BGV A1, BGR 261 are carried out by an expert.
