How to use this manual
Use this manual to get acquainted with your
centrifuge and its accessories.
The manual helps you to avoid inappropriate han-
dling. Make sure to keep it always close to the centri-
fuge.
A manual that is not kept handy cannot provide
protection against improper handling and thus
against damage to persons and objects.
The manual comprises chapters on
•Safety regulations
•Instrument description
•Rotor program and accessories
•Transportation and hook-up
•Use of the centrifuge
•Maintenance and care
•Troubleshooting
•Technical data
•Index

Safety instructions in this manual
This symbol denotes potential hazards
to persons.
This symbol denotes potential damage
to the centrifuge or parts in its imme-
diate surroundings.
Warning: hot surfaces
General danger area
Before switching on the centrifuge please
read this manual!
General hints are marked with this
symbol.
Thermo centrifuges are manufactured according to
current technical standards and regulations. Nonethe-
less, centrifuges may pose danger to individuals and
surrounding if
•they are not used as designed
•they are operated by untrained personnel
•their design is improperly changed
•the safety instructions are not followed
Therefore, personnel involved with opera-
tion and maintenance of the centrifuge
must read and follow the safety instruc-
tions.
In addition, the pertinent regulations for prevention of
accidents must be strictly followed.
This manual is an integral part of the centrifuge as-
sembly and must be kept close at hand at all times.
When damages to the power cord or at
casing are noticed the centrifuge must
be set out of operation!

Proper use
The centrifuge is designed to separate liquid-
suspended materials having different densities and
particle size (maximum sample density is 1.2 g/cm³ at
maximum speed).
Improper use
During a run, a safety zone of 30 cm around the centri-
fuge must be maintained where neither persons nor
hazardous materials may be present.
The centrifuge may cause harm to its user or other
persons or may damage goods if safety measures are
not followed:
Centrifuging hazardous materials
•The centrifuge is neither made inert, nor is it explo-
sion-proof. Therefore never use the centrifuge in an
explosion-prone environment.
•Do not centrifuge explosive or flammable sub-
stances. The same holds for substances prone to
react violently with each other.
•Do not centrifuge toxic or radioactive substances or
pathogenic micro-organisms without suitable safety
systems.
If microbiological samples of risk group II (according
to "Laboratory Bio-safety Manual" of WHO) are be-
ing centrifuged, aerosol-tight bio-seals have to be
used.
For materials in a higher risk group, more than one
precaution is required.
•Should toxins or pathogenic substances enter the
centrifuge or its parts, you must perform appropriate
procedures for disinfection (see "Maintenance and
care – Disinfection").
•Strongly corrosive substances that may cause
damage to materials and reduce the mechanical
strength of the rotor may be centrifuged only inside
protective tubes.
Handling the centrifuge
•Use only original accessories for the centrifuge. The
only exceptions are common glass or plastic centri-
fuge tubes if they are approved for the rotor speed
and RCF values.
•Never use the centrifuge unless the rotor is properly
installed.
•You may use the centrifuge only with a properly
loaded rotor. You must not overload the rotor.

For your safety

•Strictly follow the rules and regulations for cleaning
and disinfection.
•If the rotor or the rotor lid shows signs of corrosion
or wear, you must stop using it.
•Never open the lid manually if the rotor is still turn-
ing.
•You may use the emergency lid release only in
case of emergency, e.g. during an interruption of
power supply
(see chapter "Troubleshooting").
•Never use the centrifuge with an opened lid.
•Never use the centrifuge if the front panel has been
partially or totally removed.
•Changes in mechanical or electrical components of
the centrifuge may only be carried out by individuals
authorized by Thermo.
Conformity to current standards
Thermo centrifuges are manufactured and tested
according to the following standards and regulations
- for all voltages
•IEC 61010-1
IEC 61010-2-020
- for 120 V only
•
- for 230 V only
•
Please get acquainted with the details of the test
standards from the technical data
