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

For your safety
Fisher Scientific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 Fisher Scientific.

For your safety

Conformity to current standards
Fisher Scientificcentrifuges are manufactured and
tested according to the following standards and regula-
tions:
- for all voltages
• IEC 61010
- for 120 V only
•
- for 230 V only
•
Details of the test standards take you please from the
technical data.

The accuSpin™ 3 / 3R
The figure below shows a accuSpin™ 3R with the lid
open and a swinging bucket rotor installed.
Description
The accuSpin™ 3R is a general-purpose tabletop
centrifuge for biotechnological and pharmaceutic re-
search that moves high capacity centrifugation onto the
fast track. It spins more tubes, at higher RCFs, more
rapidly than competitive instruments, and can process
nominally three liters of sample in a single run. There
are various rotors with high RCF values that can ac-
commodate a wide range of accessories for all com-
mon tube types, microtiter plates and deep-wells.
The user-friendly "Easycontrol" control panel permits
easy selection of speed, RCF value, run time and run
profile (acceleration and deceleration), as well as tem-
perature of the accuSpin™ 3R. You can switch from
speed to RCF display and vice versa, with a touch of a
button and even during a run.

Description of the accuSpin ™

Safety systems
The accuSpin™ is equipped with a number of safety
systems:
• Housing and lid is constructed of 8 mm steel.
• Lid with window
• Lid lock with safety check
You can open the centrifuge lid only when the
power is turned on and the rotor has come to a
stop. You can start the centrifuge only if the lid is
properly locked.
• Automatic rotor identification
• Electronic imbalance detection as a function of rotor
(SMARTspinTM)
Do not tamper with the safety
system!
Parts supplied
Accessories supplied with the centrifuge are:
− power cord
− a special wrench for securing the rotor
(as seen in picture)
− corrosion protective oil
The printed documents consist of the delivery notes
and this Manual.

Notes

Before use
13
Before use
Centrifuge transport and installation
After opening the box remove the protective materials.
When transporting the centrifuge,
consider its weight (see „Technical
Data“); always grab it on both sides
taking care that enough helpers are
around.
Do not lift on the front panel!
The centrifuge can be damaged by
jolting during the transport!
Transport the centrifuge only in the
upright position using proper con-
tainment and secure it properly.
Handle the centrifuge carefully.
Proper location
The centrifuge may only be used indoors. Its location
must meet the following criteria:
• A safety zone of at least 30 cm (12 inches) around
the centrifuge must be maintained. Hazardous ma-
terials must not be stored beside unit while
centrifugation.
• The laboratory bench or centrifuge trolley must be
stable and resonance-free. A good support is pro-
vided by a laboratory bench or a centrifuge cart with
lockable casters.
• To ensure sufficient air circulation, a minimum dis-
tance from the wall of 10 cm (4 inches) at the back
and of 15 cm (6 inches) on each side must be kept.

Before use
14
• The centrifuge must be protected from heat and
direct sunlight.
• The location must be well ventilated at all times.
UV rays reduce the durability of
plastics.
Protect the centrifuge, rotors and
plastic accessories from direct
sunlight.
Main connection
Connect the centrifuge only to an grounded main
power supply. Make sure that the power cord is com-
patible with the safety regulations valid, and that your
main voltage and frequency correspond to the specifi-
cations on the instrument label.
Make sure that the centrifuge is switched off (on the
right-hand side of front panel) before connecting
electrical wire to main power supply.
