How to use this manual
Use this manual to get acquainted with your centri-
fuge 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

For your safety
The SORVALL®centrifuges are manufactured accord-
ing to current technical standards and regulations.
Nonetheless, centrifuges may pose danger to individu-
als 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 operation and
maintenance of the centrifuge must read and follow
the safety instructions.
In addition, the pertinent regulations for prevention of
accidents must be strictly followed
This manual is an integral part of the centri-
fuge assembly and must be kept close at
hand at all times.
When damages at the power cord or at
casing were noticed the centrifuge has
to be set out of operation!
Proper use
The centrifuge is designed to separate liquid-
suspended materials having different densities and
particle size, respectively (maximum sample density is
1.2 g/cm³ {ml} 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 user or other per-
sons 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 must not be centrifuged. The same holds
for substances prone to react violently with each
other.

For your safety
4
• Do not centrifuge toxic or radioactive substances or
pathogenic microorganisms 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 with 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 exception 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.
• 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 still turns.
• 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 the lid open.
• Never use the centrifuge if the front panel has been
partially or totally removed.
• Changes in mechanical or electrical components of
the centrifuge may be carried out only by individuals
authorized by Kendro Laboratory Products.

Conformity to current standards
SORVALL®centrifuges are manufactured and tested
according to the following standards and regulations:
- for all voltages
• IEC 61010
- for 110 V only
•
- for 230 V only
•
Details of the test standards take you please from the
technical data.
Safety instructions in this manual
This symbol denotes potential hazards to
persons.
This symbol denotes potential damage to
the centrifuge or parts in its immediate
surroundings.
General hints are marked with this
symbol.
In addition, you are asked to adhere to the pertinent
regulations, in Germany
• Regulations for prevention of accidents BGV A2
• Regulations for prevention of accidents VBG 5
• Regulations for prevention of accidents VBG 7z
- with cooled devices additionally
• Regulations for prevention of accidents BGV D4
