This centrifuge is a state-of-the-art piece of equipment which is extremely safe to operate. However, it may pose
a risk to the user or third parties if it is not used by trained personnel, improperly or in accordance with its intended
purpose.
The centrifuge should 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 24 hours in the warm room before being connected to the mains.
Only the rotors and accessories approved by the manufacturer for this device may be used, see chapter “rotor
and accessories”. Before centrifuge tube-holders, reducers, which are not listed in the chapter “rotors and
accessories”, the user should make sure they can be used by asking the manufacturer of the device.
When centrifuging with maxim revolutions per minute the density of the materials or the material mixtures may not
exceed 1.2 kg/dm

.
The centrifuge may only be operated when the balance is within the bounds of acceptability
≤ 5g = pass and ≥10g = stop
If users centrifuge hazardous materials or compounds contaminated with toxic, radioactive or pathogenic micro-
organisms, they must take appropriate work-instruction measures.
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 manufacturer can be utilised.
Components contaminated with blood (e.g. rotor, centrifugation area, waste-tube and conectors) must, following
replacement, be disposed of in the special waste for materials contaminated with blood.
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
the tests for device safety required in the respective countries, e.g. in Germany in accordance with
“DGUV Vorschrift 3”, are carried out by an expert.
