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.
Sorvall®centrifuges are manufactured according to
current technical standards and regulations. Nonethe-
less, centrifuges may pose danger to individuals and
surrounding if
xthey are not used as designed
xthey are operated by untrained personnel
xtheir design is improperly changed
xthe safety instructions are not followed
Therefore, personnel involved with oper-
ation 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!

For your safety

Proper use
This centrifuge is designed to separate sample
mixtures of different densities like chemicals,
environmental samples and other non-human body
samples.
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
xThe centrifuge is neither made inert, nor is it explo-
sion-proof. Therefore never use the centrifuge in an
explosion-prone environment.
xDo not centrifuge explosive or flammable substanc-
es. The same holds for substances prone to react
violently with each other.
xDo not centrifuge toxic or radioactive substances or
pathogenic Micro-organisms without suitable safety
systems.
If Microbiological samples of risk group II (accord-
ing to "Laboratory Bio-safety Manual" of WHO) are
being centrifuged, aerosol-tight bio-seals have to be
used.
For materials in a higher risk group, more than one
precaution is required.
xShould toxins or pathogenic substances enter the
centrifuge or its parts, you must perform appropri-
ate procedures for disinfection (see "Maintenance
and care –Disinfection").
xStrongly 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
xUse only original accessories for the centrifuge.
The only exceptions are common glass or plastic
centrifuge tubes if they are approved for the rotor
speed and RCF values.
xNever use the centrifuge unless the rotor is properly
installed.
xYou may use the centrifuge only with a properly
loaded rotor. You must not overload the rotor.
xStrictly follow the rules and regulations for cleaning
and disinfection.
xIf the rotor or the rotor lid shows signs of corrosion
or wear, you must stop using it.

For your safety
5
xNever open the lid manually if the rotor is still turn-
ing.
xYou may use the emergency lid release only in
case of emergency, e.g. during aninterruption of
power supply
(see chapter “Troubleshooting”).
xNever use the centrifuge with an opened lid.
xNever use the centrifuge if the front panel has been
partially or totally removed.
xChanges in mechanical or electrical components of
the centrifuge may only be carried out by individu-
als authorized by Thermo.

Safety systems
The LEGEND MICRO 17/21 and LEGEND MICRO 17R/21R
are equipped with several safety measures:
xHousing made of highly impact-resistant plastic;
Extra steel armor.
xLid with window and lid latch with locking mecha-
nism
You can open the centrifuge lid only when the cen-
trifuge is switched on and the rotor is standing. You
can only start the centrifuge if the lid is properly
locked.
xLid emergency release: Only in case of emergency,
e.g. the power supply is interrupted.
(see chapter “troubleshooting”)
Do not tamper with the safety systems!

Description of the instrument

Properties
TheLEGEND MICRO 17/21 and LEGEND MICRO 17R/21R
are tabletop centrifuges designed for the use in bio-
chemical and medical laboratories.
The preset speed is reached in seconds. You can also
spin samples for only a few seconds using the “quick
run” key ( ) if this is required for the task in question.
The extremely long-lived, maintenance-free induction
motor provides quiet and vibration-free operation even
at high speeds.
The user-friendly user interface “Easy control”permits
easy handling. Prior to the run, when the centrifuge is
switched on and the lid is closed, the current values
are displayed and the pre-selected set point value can
be set. While the centrifuge is operating, the display
informs of current values or (by quickly pressing one of
the “set” keys or ) the pre-selected set point val-
ues for speed/RCF and runtime, as well as tempera-
ture in the refrigerated units. After the run, the speed
control panel displays “End”.
If you press one of the keys or repeatedly, you
increase or decrease the corresponding pre-selected
set point value stepwise. If you press the chosen key
and hold it pressed, the respective chosen measure-
ment value increases or decreases continuously, at
first slowly and, after a few seconds, at an accelerated
pace.
You can change the set values during operation.
“Quick run”operation
As long as the “quick run”key ( ) is pressed, the
rotor is accelerated with maximum power (potentially
up to the maximum speed).

Before use

Before use
Where to install the centrifuge
The centrifuge may only be used indoors. Its location
must meet the following criteria:
xA safety zone of 30 cm around the centrifuge must
be maintained. Hazardous materials must not be
kept within this zone during centrifugation.
xThe substructure must be stable and resonance-
free. A good support is provided by a plane labora-
tory bench or a large laboratory carriage with cast-
ers that may be locked.
xIn the area of 15 cm around the centrifuge a suffi-
cient air circulation has to be ensured.
xThe centrifuge must be protected from heat and
direct sunshine. The ultraviolet radiation may dam-
age the housing.
xThe installation site should be always well ventilat-
ed.
Transport and installation the centrifuge
Transport the centrifuge only in
the upright position, using the
special box provided with the in-
strument, and secure it properly.
Place the centrifuge carefully to
avoid damages.
Lift up the instrument onlyon the bottom
plate. Mind the weight of the centrifuge
during the transport!
(See “Technical data”)
Let someone assist you in carrying the
centrifuge!
Centrifuge with refrigeration unit
In order to allow the coolant to set-
tle down in the compressor, the
instrument must be left idle at the
new location for approx. 1 hour.

Before use
10
Mains connection
Make sure that the mains supply and the frequency
meet the specifications printed on the centrifuge type
plate.
First turn the mains switch of the centrifuge off (press
“0”) and only then connect the centrifuge with the
mains supply using the power cord supplied.
Removing the transport protection
Before using the centrifuge, make sure
that the rotor transport protection has
been removed!
Turn the instrument on at the power switch. Open the
centrifuge lid by pressing the “open lid”key and
remove the transport protection for the rotor.
Check the free run of the rotor body by lightly turning it,
and make sure the rotor is tightly screwed and the rotor
lid is securely mounted.
