2.6 Warranty
No claim of warranty will be considered by the manufacturer unless ALL instructions in this manual have been
followed. Especially the flow-sensor and the magnetic-valve are excluded from a warranty exchange if they are
enriched with salt-crystals and this happens if the information in chapter 12 are not followed.
No claim of warranty will be considered by the manufacturer when an unauthorized modification is implemented
or non-authorized parts are installed.
3 Notes on safety
No claim of warranty will be considered by the manufacturer unless ALL instructions in this manual
have been followed.
The centrifuge should be installed on a good, stable base. We suggest that no other critical device, like
a balance, microscope or HPLC, is placed onto the same base.
The centrifuge should be set up so that no containers with e. g. liquids can fall down onto the
centrifuge
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
damage.
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.
The centrifuge may not be operated in explosion-endangered areas.
The centrifuge should not be used with:
inflammable or explosive materials
materials that react with one another producing a lot of energy
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.
