1. Notes on safety
No claim of warranty will be considered by the manufacturer unless ALL instructions in this manual
have been followed.
Reports of serious incidents involving the device
Report any serious incidents involving the device to the manufacturer and, if necessary, to the competent
authority.
•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 EN / IEC 61010-2-020, no persons, dangerous
substances or objects may be within the safety margin of 300 mm around the centrifuge.
•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.
•The centrifuge may no longer be put into operation when the centrifuging chamber has safety-
related damages.
•With swing-out rotors the trunnions must be regularly lubricated (Hettich Lubricating Grease No.
4051) in order to ensure consistent swinging out of the hangers.
•For centrifuges without temperature control, when the room temperature is increased and/or if the
device is frequently used, the centrifuging chamber could be heated up. Therefore, it can't be
ruled out that the sample material might be changed due to the temperature.
•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 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"). Before centrifuge vessels are used which are
not listed in the chapter "Appendix, Rotors and accessories", the user must make sure they can be used by
asking the manufacturer.
•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
exceed 1.2 kg/dm3.
•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.

EN
AB1701EN_SA Rev. 03 / 12.2022 9/72
•When centrifuging hazardous substances or mixtures, which are toxic, radioactive or contaminated with
pathogenic microorganisms, suitable measures must be taken by the user.
Fundamentally, centrifuge containers with special screw closures must be used for hazardous substances. For
materials of risk groups 3 and 4, in addition to sealable centrifuge containers, a bio-safety system must be used
(see the "Laboratory Bio-safety Manual" from the World Health Organization).
In a bio-safety system, a bio-seal (sealing ring) prevents droplets and aerosols from escaping.
If the hanger of a bio-safety system is used without the lid, the sealing ring must be removed from the hanger to
prevent damage to the sealing ring during the centrifugation run.
Damaged bio-safety systems are no longer microbiologically sealed.
If a bio-safety system is not used, a centrifuge is not microbiologically sealed for the purposes of the standard EN
/ IEC 61010-2-020.
When closing a bio-safety system, follow the instructions in the chapter "Closing biosafety systems".
For the available bio-safety systems, see the chapter "Appendix, Rotors and accessories". If in doubt, you can
get the information you need from the manufacturer.
•The centrifuge must not be operated with highly corrosive substances which could impair the mechanical integrity
of rotors, hangers and accessories.
•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:
EN / IEC 61010-1 and EN / 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 EN / IEC
stipulations.
•Meeting the country-specific requirements concerning occupational safety with regard to the use of laboratory
centrifuges at the workplaces provided for this purpose by the user is the responsibility of the user.

•The maximum filling quantity for the centrifuge containers specified by the manufacturer must not be exceeded.
In the case of angle rotors, the centrifuging
vessels may only be filled so far that no fluid
can be expelled from them while the centrifuge
is running.
Fluid
Centrifugal force
•When loading the angle rotors, no liquid may get into the angle rotors or centrifuging chamber.
•When loading the hangers and swing-out rotors and when swivelling out the hangers while the centrifuge is
running, no liquid may enter the hangers or the centrifuging chamber.
•In order to maintain the weight differences within the centrifuge container as marginal as possible, a consistent
fill level in the containers is to be heeded.
7 Closing biosafety systems
In order to guarantee that it is sealed, the lid to the biosafety system has to be firmly closed.
In order to prevent the packing ring from twisting when opening and closing the cover, the packing ring must
be lightly rubbed with a rubber care product.
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.
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.
