1.1 Usage in accordance with safety standards
1.1.1 General information
1.1.1.1 Hazards and precautions
Before operating the centrifuge, please read this instruction manual carefully!
This centrifuge must not be operated by unqualified personnel not familiar with the
correct use of the unit.
• Use the original accessories only!
• The centrifuge is not explosion-proof and therefore must not be operated in areas
where there is a risk of explosion. During centrifugation, it is prohibited to stay or
place hands within the safety zone of 30 cm around the centrifuge or deposit hazard-
ous substances within this area.
• Centrifugation of flammable, explosive and radioactive substances or substances
which chemically react with high energy is strictly prohibited!
• Never spin toxic or pathogenic material without adequate safety precautions, i.e.
centrifugation of buckets / tubes without or with defective hermetic sealings is strictly
prohibited. The user is obligated to perform appropriate disinfection procedures in
case dangerous substances have contaminated the centrifuge and / or its accesso-
ries. When centrifuging infectious substances, always pay attention to the General
Laboratory Precautions. If necessary, contact your safety officer!
• It is prohibited to run the centrifuge with rotors other than those listed for this unit.
• Under no circumstances open the lid of the centrifuge while the rotor is still running
or rotating with a speed of > 2 m/s.
The following rules must strictly be adhered to:
• Do not operate the centrifuge if it is not installed correctly.
• Do not operate the centrifuge when disassembled (e.g. without metal cover).
• Do not run the centrifuge when mechanical or electrical assembly groups have
been tampered with by unauthorized persons.
• Do not use accessories such as rotors and buckets, which are not exclusively
approved by the manufacturer, except commercially available centrifuge tubes made
of glass or plastic.
• Do not spin extremely corrosive substances, as they may damage the centrifuge
and rotors and impair mechanical resistance.
• Do not operate the centrifuge with rotors or buckets which show any signs of
corrosion or mechanical damage.

• European Standard PR EN 61 010-1 and PR EN 61 010-2-2

1 PRODUCT DESCRIPTION
1.1.1.4 Included items
Following parts are supplied as accessories with each centrifuge:
• 2 fine-wire fuses 1,25 AT (230 V)
• 1 fine-wire fuse 0,50 AT (230 V)
• 2 fine-wire fuses 2,50 AT (120 V)
• 1 fine-wire fuse 0,10 AT (120 V)
• 1 instruction manual
Spare fuses are behind the control panel inside of the centrifuge.
1.1.1.5 Warranty
The centrifuge has been subjected to thorough testing and quality controls.
In the unlikely case of any manufacturing defects, the centrifuge and rotors are
covered by warranty for a period of two years from date of delivery.
This warranty becomes invalid in case of mishandling, damage and negligence and
further in the case of the use of inappropriate spare parts and / or accessories or
unauthorized modification of the unit.
Technical modification rights are reserved by the manufacturer with respect
to technical improvement.
1.2 Installation
1.2.1 Installation of the centrifuge
1.2.1.1 Unpacking the centrifuge
The centrifuge is supplied in a carton.
Open the carton, remove the cover carton and the centrifuge. The instruction manual
must always be kept with the centrifuge.
1.2.1.2 Space requirements
The centrifuge should be installed on an even and solid surface, if possible on a
laboratory cabinet / table or some other solid vibration free surface. In order to enable
a safe and smooth operation, level the centrifuge with a spirit level. The centrifuge
must be located with a minimum space of 30 cm on each side of the unit in order to
ensure necessary heat dissipation. Do not place the centrifuge next to a window or a
heater, where it could be exposed to excessive heat.
Safety regulations require that the safety area of 30 cm around the unit is marked in
order to indicate that neither hazardous substances nor persons should be within this
area during centrifugation.

1.2.1.3 Installation
Be sure to check the following before installation:
• Check that the power supply corresponds the the information on the manufacturer’s
rating label which is mounted on the rear panel.
• The line voltage circuit breaker is 15A minimum.
• An emergency switch off is installed outside the room in order to disconnect the
power supply of the unit.
• The wooden motor shaft transport brace block has been removed.
The socket for the power cord must be easy to reach and respectively easy to
disconnect!

2 OPERATION
2.1 Installation of rotors
2.1.1 Mounting and loading angle rotors
Clean the motor shaft as well as the rotor mounting boring with a clean, grease-free piece of
cloth. Place the rotor onto the motor shaft, ensuring that the cross pin aligns correctly with
the rotor slot (see photos 1 and 2).
A partially loaded rotor may be used (ie an 8 place rotor with 2 or 4
tubes loaded). The load must be balanced and the tubes must be
opposite each other. See image below.
Photo 4: Incorrect Photo 5: Correct
Hold the rotor with one hand and secure the rotor to the shaft by turning the rotor nut
clockwise. Tighten rotor nut.

2 OPERATION
2.1.2 Mounting and loading swing out rotors
Clean the motor shaft, as well as the shaft hole in the rotor with a clean and grease-
free cloth. Place the rotor on the motor shaft, taking care that the cross pin is sitting in
the rotor slot (photo 1 and photo 2). Hold the rotor with one hand and secure the rotor
to the shaft by turning the rotor nut clockwise. Tighten rotor nut by hand.
The loading of the buckets and the adapters must be done appropriately so that the
load is balanced with tubes in opposing tube holders. Tubes must be filled evenly by
eye. Weight difference of loaded tubes should not exceed 1g.
2.1.3 Overloading of rotors:
The maximum load permitted for a rotor, which is determined by the manufacturer, as
well as the maximum speed allowed for thie rotor (see label on rotor), must not be
exceeded. Liquids to be centrifuged should have an average homogeneous density
of 1.2 g/ml or less when the rotor is spinning at maximum speed. In order to centri-
fuge liquids with a higher density, the speed must be reduced according to the follow-
ing formula:
Reduced speed n = x max. speed (nmax) of the rotor
Example
nred = x 4,000 = 3,360rpm
If in doubt, contact the manufacturer!
2.1.4 Removing the rotor
Hold the rotor with one hand. Loosen the rotor nut byturning it conterclockwise.
ATTENTION:
Do not operate the centrifuge with rotors which show any signs of corrosion
or mechanical damage.
Do not centrifuge extremely corrosive substances which could damage the
rotor.
