How to use this manual
Use this manual to get acquainted with your centrifuge
and its accessories.
The manual helps you to avoid inappropriate handling.
Make sure to keep it always close to the centrifuge.
A manual that is not kept handy cannot provide
protection against improper handling and thus
against damage to persons and objects.
This manual comprises chapters on
• Safety regulations

For your safety
Heraeus centrifuges are manufactured according to
current technical standards and regulations. Nonethe-
less, centrifuges may pose dangers if
• they are not used as designed
• they are operated by untrained personnel
• their design is improperly changed
• the safety instructions are not heeded
Therefore anybody concerned with operation and
maintenance of the centrifuge must read and fol-
low 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.
Proper use
The centrifuge is designed to separate liquid-
suspended materials having different densities and
particle size, respectively. The maximum sample den-
sity is 1.2 g/cm3at 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 stationed.
The centrifuge may cause harm to you or other per-
sons and may damage material goods if you do not
respect the following safety measures:
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.
• Explosive or flammable substances must not be
centrifuged. The same holds for substances prone
to react briskly with each other.

For your safety
4
• Do not centrifuge toxic or radioactive substances or
pathogenic microorganisms unless you have taken
proper precautions.
Such precautions can e.g. consist of biological
seals.
• Should toxins or pathogenic substances enter the
centrifuge or its parts, you must carry out the proper
procedures for disinfection (see "Maintenance and
care – Disinfection").
• Strongly corrosive substances that may cause
damage to materials and impair the mechanical
strength of the rotor may be centrifuged only inside
protective vessels.
Handling
• Never use the centrifuge unless the rotor is properly
mounted.
• Never manually open the lid if the rotor still turns.
• Use only original parts for the centrifuge. The only
exception are common glass or plastic centrifuge
tubes if these are approved for the rotor speed and
RCF values of your rotor, respectively.
• Never use the centrifuge with the lid open.
• Never use the centrifuge if the paneling has been
partially or totally removed.
• Changes in mechanical or electrical components
may be carried out only by persons authorized to
this effect by KENDRO Laboratory Products.
• You may use the centrifuge only with a properly
loaded rotor. You must not overload the rotor.
• If the rotor or the lid shows visible traces of corro-
sion or wear, you must stop using it.
• Strictly follow the rules and regulations for cleaning
and disinfection.

For your safety

Conformity to current standards
Heraeus centrifuges are manufactured and tested
according to the following standards and regulations:
for all voltages:
• IEC 1010-1 / EN 61010-1
• IEC 1010-2 / EN 61010-2-020
− Pollution degree 2
− Overvoltage category II
for 120 V only:
• CAN/CSA-C22.2 No. 1010.1-92
• CAN/CSA-C22.2 No. 1010.2.020-94
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 sur-
roundings.
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 VBG 4
• Regulations for prevention of accidents VBG 5
• Regulations for prevention of accidents VBG 7z
• Regulations for prevention of accidents VBG 20

The Biofuge primo R
The figure below shows a general view of the Biofuge
primo R with open lid and the rotor put into place.
Safety systems
The Biofuge primo R is equipped with a number of
safety systems:
• Housing and rotor chamber manufactured from
sheet steel; inner armoring made of steel, front
screen made from impact-resistant plastic
• Lid with window and lid lock
You can open the centrifuge lid only when the
power is turned on and the rotor has come to a halt.
You can start the centrifuge only if the lid is properly
locked.
• Rotor identification
• Electronic unbalance detection
• Emergency lid release: only in case of emergency,
e.g. during power failure (see chapter "Trouble-
shooting"
Do not tamper with the safety systems!

Properties
The Biofuge primo R is a laboratory centrifuge for use
with a variety of rotors and a large number of commer-
cially available centrifuge tubes.
The preset speed is reached in seconds. The mainte-
nance-free induction motor provides quiet and vibra-
tion-free operation even at high speeds and warrants
an extremely long lifetime.
The user-friendly "Easycontrol" control panel permits
easy preselection of speed, RCF value, run time,
temperature and run profile (acceleration and braking
behavior). You can switch from speed to RCF display
or entry and vice versa.
You can change the set values even during a run.
With the "quick run" key ( ) you can centrifuge a
sample for only a few seconds if that is required for
your particular task.
Items delivered
Items delivered with the centrifuge comprise:
− a special cap nut for fixing the rotor
− 10-mm tubular socket wrench for fastening the
cap nut
− power cord
− short operating instructions
The printed documents consist of the delivery notes
