1 Intended application

The centrifuge is used for separating substances or mixtures with a density of up to max.

1.2 kg/dm³. Through the production of centrifugal force it can separate mixtures or alter the proportions in a mixture.

If the substance or mixture to be centrifuged is denser than 1.2 kg/dm³, the rated speed should be reduced (see section “Centrifuging of denser substances”).

2 Notes on safety

• 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.

• Before the initial operation of your centrifuge you should read and pay attention to the

operating instructions.

• 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.

• The centrifuge should be installed on a good, stable base.

• When setting the equipment up you should pay attention to the following points:

− A 300 mm safety zone must be established around the centrifuge in accordance with

IEC 1010-2-2.

− This safety zone must be kept clear of both people and hazardous substances at all

times when the centrifuge is in operation.

− According to the laboratory instrument standards EN 61010-2-20 an emergency

switch to separate power supply in the event of a failure must be installed in the building electrical system. This switch has to be placed remote from the centrifuge, prefered outside of the room in which the centrifuge is installed or near by the exit of this room.

• Do not place any object in front of the ventiduct.

− Keep a ventilation area of 300 mm around the ventiduct.

• The centrifuge should always be loaded evenly.

• Centrifuge containers must not be filled beyond the capacity specified by the

manufacturer.

− Centrifuge containers should only be filled outside the centrifuge.

• Standard centrifuge containers of glass will not stand RCF values exceeding 4000 (DIN

58970, pg. 2)

• No attachments should be used other than those authorised by the manufacturer.

• Centrifuge containers may only be centrifuged with accessories (reducing adapters,

frames, suspensions, etc.) authorised by the manufacturer (see section "Rotors and accessories).

• 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 61010-2-20. 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 “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.

• Any rotors, hangers or accessories showing clear signs of corrosion or mechanical

defects must not be used for centrifuging.

• In order to prevent corrosion developing through cleaning or disinfectant agents, it is

most important that any specific instructions from the manufacturers of such agents should be followed carefully. Before applying any cleaning or disinfecting procedure other than those recommended by the manufacturer, the user should contact the manufacturer to make sure that the planned process will not damage the equipment.

• Only original spare parts and authorised original accessories may be used.

• In case of fault or emergency release, never touch the rotor before it has stopped

turning.

• This centrifuge is classified in Germany as a Group 3 device according to the

Medizinische Geräteverordnung MedGV (the regulations on medical equipment).

• It conforms to safety regulations based on:

IEC 1010-1/-2 DIN - EN61010 Parts 1and 2

• The safe operation and reliability of the centrifuge can only be guaranteed if:

− the centrifuge is operated in accordance with the operating instructions,

− repairs are carried out by engineers approved by the manufacturer,

− the electrical installation on the site where the centrifuge is installed conforms to the

demands of IEC stipulations,

− prescribed tests to UVV-VBG7z are carried out by an expert.

• With centrifuges for robotic use please pay attention to the notes of the key operated

switch.

No claim under guarantee will be considered by the manufacturer unless the above instructions have been adhered to.

3 Warning symbols

Caution! Follow instructions carefully.

Load centrifuge rotor evenly. All positions on rotor must be filled.

Do not fill centrifuge containers inside the centrifuge.

• The necessary space requirement can be found under Dimensions in the Technical

data chapter.

• The centrifuge must be set up in a suitable place, so that it is stable. During set up

the required safety area of 300 mm around the centrifuge, in accordance with IEC 1010-2-2, must be observed.

Persons and hazardous materials must not be located in the safety area whilst the centrifuge is in operation.

• Do not place any object in front of the ventiduct.

− Keep a ventilation area of 300 mm around the ventiduct.

8 Connection to the mains

• Check whether the supply voltage, supply frequency and on-site mains fuse agree

with the specification on the nameplate. The nameplate is located on the back of the centrifuge.

• Make sure that the mains switch is in the “0” position.

• The centrifuge must be connected to a standard mains socket using the power

supply cable provided.

9 Commissioning

• Check that the centrifuge has been properly set up and that the electrical

connections are correct (see Connection to the Mains and Space Requirement).

• Switch the mains switch “ON”, switch position “I”.

After a short time the control panel will switch on and the last set parameters will appear in the displays.

• When the symbol has lit up, the lid can be opened.

• Open the lid and remove the transport protection (see Transport Protection

information sheet).

10 Opening the lid

• When the symbol has lit up, the lid can be unlocked and opened.

• Unlock the lid by turning the swivel clamp upwards.

• The symbol appears.

• Open the lid.

The lid can only be opened if the centrifuge is switched on and the rotor is stationary. If this is not possible, see chapter “ Emergency release “.
