reminder.
1-2. Safety Precautions
Before using the instrument, please read this operation manual to ensure correct usage through
understanding. Incorrect handling of the instrument could possibly result in personal injury or physical
damage on the instrument or its accessories.

3
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.
9ALWAYS 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°C – +35 °C, Relative humidity: ≤85%)
4. Should not use a power source other than the instrument designed to operate on.
5. Should not use unapproved rotors and associated components.
9Only use rotors from Dynamica 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 securely fastened.
9Should operate the instrument with a rotor properly installed and secured to the
motor shaft.
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 door open should be performed only when spinning is completely stopped.
10. Should not exceed the rated speed or specific 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 lowest value of the individual guaranteed g-
forces among the 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 time and safety.
15. ALWAYS disconnect the power supply prior to maintenance and servicing to avoid electrical
shock.
16. ALWAYS use proven disinfection procedures after centrifuging biohazardous materials.
17. Should not centrifuge flammable, toxic, radioactive, explosive, or corrosive materials.

4
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.
9Do not place dangerous materials within 30cm distance around the instrument,
and that is also recommended by IEC 61010-2-020.
9Use the emergency door open function only when the door button on the control
panel is dumb under the condition of complete stop of rotor running.
9Never try to open or move the instrument if it is not completely stopped.
9If the power input is more than +/- 10% of the recommended voltage or fluctuates
frequently, it may cause malfunction of the instrument and often result serious
damage.
9Install the instrument at the place without any kinds of corrosive gases.

3-3. Positioning of Sample Tubes
Action
1. Before loading sample tubes, check the water drop or dirt in the rotor hole or inner adaptor.
¾If there is a water drop or dirt in the rotor hole or inner adaptor, remove it with soft
dry cloth.
2. Tubes should be placed in the rotor with same amount of samples and symmetrical positions.
¾Only use appropriate centrifugal tubes and do not exceed the speed beyond the
tube’s max g-force.
¾For safety, fill the sample for 70~80% in the tubes.

Correct Ways of Sample Balancing & Tube usage
☞If the number of samples is not in pair, please load the control tubes at each symmetrical position.
Otherwise, it results noise and vibration, which eventually damages the instrument.

“Emergency Door Open Hole” at the bottom of the instrument
2. Insert spikes (a car key, scissors and etc.) 2~3cm into the

13
“Emergency Door Open” hole and pull the spikes at the opposite
direction of the arrow.
5. Maintenance
5-1. 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 contaminated area. Keep completely dry after cleaning.
2. Do not use any volatile chemicals such as alcohol and benzene, etc.
3. Be careful not to make scratches on the surface of the instrument. The scratches can cause
corrosion on the surface of the instrument.
9If any rust appears, clean it with neutral detergents and keep dry.
5-2. Chamber
1. Keep dry inside the chamber after every use.
2. If the chamber is contaminated, dip the cloth in neutral detergent and clean contaminated
area.
5-3. Shaft
1. Always make special attention to clean the motor shaft to avoid any imbalance problem due
to 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.
5-4. Rotor
1. If any parts are contaminated with samples, clean the rotor 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. If you do not use the instrument, keep the rotor separately from the motor shaft and stand it
upside down.
Manual opening should be performed only when spinning is completely stopped.
Otherwise, harmful damage will be accompanied to not only operators but samples.
After opening the door manually, it is recommended to wait until normal electricity
comes back.

14
5-5. Transportation of the instrument
1. If you need to move or ship the instrument, be cautious to protect the motor shaft from any
physical impact or turbulence.
2. Do not mount a rotor in any cases of movement. Fill inside the chamber with proper materials
to keep the motor shaft on place and not to be influenced by physical pressure.
6. Trouble Shooting
6-1. Check list
Symptom Check list
Power failure
Connect the AC Power cord and make sure that the line is completely
connected between the instrument and power outlet. Check the
power switch is turned on. (Please refer to 3-1. Power On/Off)

minimize the noise
1. the balanced way of coupling of the rotor into the motor
shaft
2. the completeness of fixing of the Rotor Locking Nut on the
rotor
3. the matching status of Rotor Lid with the rotor
