Precautions
Signal Words and Colors
WARNING Indicates a hazardous situation that, if not avoided, could result in
death or serious injury.
CAUTION Inidicates a hazardous situation that, if not avoided, could result in
minor or moderate injury (e.g. sample loss).
NOTICE Indicates information considered important, but not hazard-related
(e.g. messages relating to property damage).
NOTICE
Observe the safety instructions� Not following these instructions can cause damage�
The centrifuge is to be used for its intended use only� Improper use can cause damages,
contamination, and injuries with fatal consequences�
Set Up Conditions
Set up in a well-ventilated environment, on a horizontally levelled and rigid surface with
adequate load-bearing capacity�
As safety zone maintain a clear radius of at least 30 cm around the centrifuge�
Do not place any dangerous substances within this security zone�
Plug the centrifuge only into sockets which have been properly grounded�
The mains plug must be freely accessible at any time�
CAUTION
Not following the set up conditions can result in minor or serious injuries�
Shutdown
Turn off the centrifuge at the main switch�
The mains plug must be freely accessible at any time�
Press the STOP key to shut down the centrifuge�
Pull out the power supply plug or disconnect the power supply in an emergency�

Preparation
Use only with a rotor that has been properly installed� Follow the instructions in section
“Rotor Installation” on page 29�
Do not use a rotor or accessories that show any signs of corrosion or cracks�
Contact customer service for further advice or inspections�
Use only with a rotor that has been properly loaded�
Never overload the rotor�
Always balance the samples�
Use only rotors and accessories for this centrifuge that have been approved by Thermo
Fisher Scientific�
Make sure the rotor is locked properly into place before operating the centrifuge�
WARNING
It is the obligation of the operator to make sure, that protective clothing is used� Mind the “Laboratory
Biosafety Manual” of the World Health Organization (WHO) and the regulations in your country�
CAUTION
Implement measures which ensure that no one can approach the centrifuge for longer than
absolutely necessary while it is running�
Do not use a damaged rotor� Replace the rotor, if it was dropped�
Hazardous Substances
WARNING
Especially when working with corrosive samples (salt solutions, acids, bases), the accessory
parts and vessel have to be cleaned thoroughly�
Do not centrifuge explosive or flammable materials or substances�
The centrifuge is not inert or protected against explosion� Never use the centrifuge in an
explosion-prone environment�
Do not centrifuge toxic or radioactive materials or any pathogenic micro-organisms without
suitable safety precautions�
If any hazardous materials are centrifugated, mind the “Laboratory Biosafety Manual” of the
World Health Organization (WHO) and any local regulations� When centrifuging microbiological
samples from the Risk Group II (according to the “Laboratory Biosafety Manual” of the World Health
Organization (WHO)), aerosol-tight biological seals have to be used� Look on the internet page of the
World Health Organization (www�who�int) for the “Laboratory Biosafety Manual”� For materials in a
higher risk group, extra safety measures have to be taken�

If toxins or pathogenic substances have contaminated the centrifuge or its parts, appropriate
disinfection measures have to be taken (“Disinfection” on page 49)�
Extreme care should be taken with highly corrosive substances which can cause damage
and impair the mechanical stability of the rotor� These should only be centrifuged in fully
sealed tubes�
If a hazardous situation occurs, turn off the power supply to the centrifuge and
leave the area immediately.
Operation
WARNING
Never use the centrifuge if parts of its cover panels are damaged or missing�
Do not move the centrifuge while it is running�
Do not place anything on top of the centrifuge during a run�
CAUTION
Do not lean on the centrifuge�
Never open the centrifuge door until the rotor has come to a complete stop and this has
been confirmed in the display�
The emergency door release may be used in emergencies only to recover the samples from
the centrifuge, e�g� during a power failure (“Mechanical Emergency Door Release” on page
52)�
NOTICE
In any case of severe mechanical failure, such as a rotor crash, the centrifuge is not aerosol-tight�
In case of rotor failure the centrifuge can be damaged� Leave the room� Inform customer service�
Maintenance
WARNING
The centrifuge housing is not to be opened by the operator�
Do not change or replace mechanical or electrical components� Changing or replacing
components can result in death or serious injury�

Service Lifetime
The centrifuge is designed for 10 years or 140 000 cycles of service, whichever is first� Usage
beyond these limits might affect the safety of the centrifuge housing or the lid latch system�
The rotor is designed for 5 years or 60 000 cycles of service, whichever is first� Usage beyond these
limits might lead to rotor failure, sample loss and damage to the centrifuge�
