This manual is for the users who operate the device for the rst time.
This manual provides information on the detailed instructions, precaution,
troubleshooting and maintenance care.
1. Meanings of Symbols & Safety Precautions
1.1 Safety Labels on Instrument
The labels on the instrument represent safety instructions and directions.
Symbol Meaning Symbol Meaning
Attention and warning Attention and warning for
electric shock
Symbol Meaning
Attention and warning for correct way of
samplebalancing in the rotor.
Attention and warning for rotor coupling.
Attention and warning for door opening and closing.
1.2 Safety Precautions
Before using the instrument, please read this operation manual to ensure correct usage. Incorrect
handling of the instrument could possibly result in personal injury or physical damage on the
instrument or its accessories.
1. ALWAYS locate the instrument on a flat, rigid and stable table capable of withstanding the weight
of the instrument and its spinning operation.
2. ALWAYS make a safety zone of 30 cm around the centrifuge to indicate that neither hazardous
materials nor persons should be permitted within the area during operation.
ALWAYS position the instrument with enough space on each side of instrument to ensure
proper air circulation.
3. ALWAYS install the instrument within a temperature and humidity controlled environment.
(Permissible ambient temperature: +5℃~ +35 ℃, Relative humidity: ≤85%)
4. Before connecting the power, check the rated voltage.
5. Should not use unapproved rotors and associated accessories.
Only use rotors from Gene Company Limited with appropriate centrifugal tubes and suitable
adaptors to embrace sample containers tightly enough inside rotors.
6. Before operating the instrument, check if the rotor and the rotor lid are securelyfastened.
Should operate the instrument with a rotor properly installed and secured to the motor shaft.

GENESPEED®GENESPEED®
7. Mount the rotor on the motor shaft properly, check it with spinning manually.
8. Do not stop the rotor by touching with hand during the instrument is running.
9. Emergency lid open should be performed only when spinning is completely stopped.
10. Should not exceed the rated speed or specic gravity. Samples whose density is greater than 1.2g/
ml must have reduced maximum rotational speed to avoid rotor failure.
11. The sample content should not exceed 80% of total capacity of a tube. Otherwise, it would cause
spillage of sample fluid and even the tube breakage.
12. ALWAYS load the tubes symmetrically with evenly weighted samples to avoid rotor imbalance.
If necessary, use the water blank to counterbalance the unpaired sample.
13. The operation speed should not exceed the highest value of the individual guaranteed g-forces of
each centrifuge, rotor, bucket or adaptors and sample container, especially the guaranteed g-force of
sample container should not be neglected.
14. The rotors should be cleaned and kept dry after every use for longer life and safety.
15. ALWAYS disconnect the power supply prior to maintenance care and service to avoid electrical
shock.
16. ALWAYS use proven disinfection procedures after centrifuging biohazardousmaterials.
17. Should not centrifuge flammable, toxic, radioactive, explosive, or corrosive materials.
18. When it is necessary to use toxic or radioactive materials or pathogenic micro-organisms which
belong to the Risk Group II of WHO: “Laboratory Bio- safety Manual,”should follow national
regulations.
Do not place dangerous materials within 30 cm distance around the instrument, and that is also
recommended by IEC 61010-2-020.
Use the emergency lid open function only when the lid button on the control panel is dumb
under the condition of complete stop of rotor running.
Never try to open or move the instrument if it is not completely stopped.
If the power input is more than +/- 10% of the recommended voltage or uctuates frequently, it
may cause malfunction of the instrument and often result serious damage.
Install the instrument at the place without any kinds of corrosive gases.

3.2 Rotor Coupling and Disassembling
3.2.1 Fixed Angle Rotor
Action
Before coupling a rotor, clean the motor shaft, rotor, and chamber
with soft dry towel.
If you ndany foreign substances, they must be removed from
the motor shaft, rotor and chamber.
Mount a proper rotor into the motor shaft and x it using Rotor
Locking Tool.
To assemble the rotor, rotate the Rotor LockingToolclockwise
until tightly assembled.
To disassemble the rotor, rotate the Rotor LockingTool
counterclockwise.
Grasp the rotor with one hand and assemble or disassemble the
rotor using the Rotor Locking Tool.

Note!
•The lid is not opened while the instrument is running.
•If the lid is opened, the instrument could not be operated even with pressing the [ ]
button.
•For operational safety, this instrument has the automatic rotor recognition function.
•When you supply the power, "Rotor Scan…” will be appeared. If the rotor is absent,
the “Error 9”will be appeared. This message will be cleared after rotor coupling and
running.
•The lid is not automatically opened after nishing operation to keep the sample at proper
temperature.
•Power Failure: If there is any power failure during the operation, lid is not opened with
[ ] button. The lid can be opened only when the operation is completely stopped and
the power is on again. If you want to open the lid at the power failure, please refer to
‘4.10
Emergency Lid Open’.

After placing the sample tubes into the holes of the rotor, close the
rotor byrotating the rotor lid nut clockwise.
To close the rotor lid, rotate clockwise.
To open the rotor lid, rotate counterclockwise.
3
Caution!
•When you run a xed angle rotor, make sure that the rotor lid is tightly closed. If you
don’t close the rotor lid completely, it will be crushed.
3.3 Positioning of Sample Tubes
Action
Before loading sample tubes, check the water drop or dirt in the
rotor hole or inner adaptor.
If you nd any water drops or dirt in the rotor hole or adaptor,
remove them with soft and dry cloth.
The sample tubes should be placed in the rotor holes in a balanced
way.
The sample tubes should be loaded symmetrically with the
density andthe weight considered to avoid imbalance.
In case the number of samples cannot make balance in weight,
please use control tubes. Otherwise, it can cause noise or vibration,
which may damage the instrument.
Only use appropriate centrifugal tubes and do not exceed the
speed beyond the tube’s max g-strength.

Note!
•For the safety, the instrument has ‘Imbalance Cut-off’function to sense the imbalance
of the loaded tubes.

5. Maintenance
5.1 Outer Part of Instrument, Chamber, Shaft and Rotor
Outer Part of Instrument
1. Clean the outside of the instrument with dry soft cloth. If necessary, dip the cloth in neutral
detergent and clean any contaminated area. Keep completely dry after cleaning.
2. Do not use any volatile chemicals such as alcohol, benzene, benzole, and thinner, etc.
3. Be careful not to make scratches on the surface of the instrument.
Scratches may cause corrosion on the surface of the instrument.
Any parts with rust should be cleaned with neutral detergents and kept dry.
Chamber
1. Keep dry inside the chamber after every use.
2. If the chamber is contaminated, clean contaminated area with the cloth dipped in neutral
detergent.
Shaft
1. Always keep the motor shaft clean to avoid any imbalance problem caused by the
contaminants.
2. After using the instrument, take out the rotor from the shaft and clean the shaft with dry soft
cloth to keep dry.
3. If the rotor cannot be easily removed from the shaft, do not pull the rotor by force and call a
service engineer authorized by Gene Company Limited.
Rotor
1. If any parts become contaminated, clean them with soft wet cloth and keep the rotor dry.
2. Be careful not to make scratches inside or on the surface of rotors. Any small scratches can
cause corrosion of the rotor and big damage to the instrument.
3. While the instrument is not used, remove the rotor from the motor shaft and stand it upside
down.
