⚫Do not place any dangerous materials within 30cm radius of this centrifuge.
⚫When separating any toxic, radioactive materials or pathogenic micro-organism, necessary safety
measures must be taken and the user will be liable for any resulting negative consequences.
⚫If the centrifuge, rotor and accessories that have been contaminated by solutions with toxic, radioactive

or pathogenic materials, clean it according to the decontamination procedures specified.
⚫If you require service at site, please sterilize and decontaminate the centrifuge in advance, and then
notify the service center about the details of the materials and procedure.
⚫For safety purposes not enter within 30cm around this centrifuge when it is in operation.
⚫To avoid electrical shocks, ensure your hands are drybefore handling the power cord or turning On/Off
the power switch.
⚫For safety purposes do not enter within 30cm around this centrifuge in operation mode.
⚫Don’t open the centrifuge lid while the rotor is in operation.
⚫Unauthorized repairs, disassembly, or modifying the centrifuge except by our service center are
strictly prohibited.
Caution
•Ensure this centrifuge is placed on a solid, flat and firm table.
•Ensure that the centrifuge is on flat level table before operation.
•Ensure that the angle between the housing and upper lid is larger than the 70 degrees while opening
the lid.
•Do not put your fingers or hands in-between the housing and upper lid while closing the lid.
•Do not move/ relocate the centrifuges/ lean against it when the centrifuge is in operation.
•If there is any liquid spillage in the rotor chamber, please promptly clean and dry with a dry cloth to
avoid sample contamination.
•Keep the centrifugal chamber clean and ensure to remove any foreign particles dropped
inside the rotor chamber, before running the centrifuge.
•Cautions about rotor
(1) Check the rotor surface for corrosion or damage before use and do not use it if any problem is
found.
(2) Do not set the speed beyond the allowable minimum speed of the rotor (rotor and adapters). Make
sure to run it below the maximum speed.
(2) Do not exceed the allowable imbalance.

(3) The centrifuge tubes should be within the centrifuge actual capacity.
(4) If the rotor has a cover, be sure to tighten the cover before operation.
(5) If the rotor is provided with a lid, ensure it is secure it tightly before operation.
⚫If there is any abnormality observed during operation, Ensure to stop the centrifuge immediately,
contact the service center and inform about the failure code if displayed.
⚫Vibrations are likely to damage the centrifuge, contact our service center if abnormality observed.

(2) Range of relative humidity: ≤93%RH

4. Installation and testing
Users must strictly comply with the installation instructions contained in this chapter. Be advised!
Warning
⚫Improper power connection might damage the centrifuge.
⚫Ensure to check the power supply before connection for compliance with the requirements.
4.1 Mounting position
(1) Place this centrifuge on a firm、flat and level surface, ensure the four feet of this centrifuge stand on the
counter firmly.Avoid installing on a slippery surface or surface prone to vibration.
(2) Ideal ambient temperature is 20℃±5℃, avoid placing the centrifuge in direct sunlight if temperature
(3) exceeds 30℃.
(4) Ensure to clear 10cm from the centrifuge on both sides and behind the centrifuge in order to ensure
air cooling efficiency.
(5) Prevent heat/water leakage near centrifuge, otherwise the rise in sample temperature or centrifuge
failure might occur easily.
4.2 Connection between power cable and ground wire
Warning
⚫Don’t touch the power cable or power switch with wet hands to avoid electric shock.
⚫This centrifuge must be properly grounded.
A minimum of 10A outlet providing a good grounding terminal is required and needs to meet the local
safety requirements.

elapsed time to the total time.
7. Rotor preparation
7.1 Prepare the samples to be separated
7.2 Transfer the samples into the centrifuge tube
Caution
⚫Ensure that the centrifuge tubes are not overloaded with the samples which will result in leakage.

⚫Do not exceed the actual tube capacity as mentioned in this user manual.
7.3 Ensure the balanced centrifuge tube
⚫Although the centrifuge may be used with visually confirmed balance, it is recommended that the
samples are weighed using a balance to keep this centrifuge in a well-balanced condition to extend its
life expectancy.
⚫Never intentionally run the centrifuge under an imbalance condition even though the allowable
imbalance is not exceeded.
7.4 Check rotor
Ensure to check the rotor for any corrosion or scratch before every operation.
Caution
⚫If any corrosion or scratch is found on the rotor, please cease to use the rotor.
⚫Avoid the use of other manufacturer’s rotor on this centrifuge.
7.5 Symmetrically load centrifuge tubes into rotor
Caution
⚫Ensure to secure the rotor on the main shaft firmly. Otherwise, the rotor might fall off while the
centrifuge is in operation, resulting in damage to the centrifuge or rotor.
⚫Tighten the rotor lid to the rotor firmly.
8. Operation
8.1 Normal operation
The display screen is lit when the power switch is turned ON, and the centrifuge shows HELLO page, as
shown in Fig. 8.1.
Caution
⚫Avoid moving the centrifuge when it is in operation mode.
⚫Keep the centrifugal chamber clean and ensure to remove foreign particles from the centrifugal
chamber, such as fragments of broken centrifuge tubes if any.
⚫If any abnormal/ strange noise is noticed from the operating centrifuge, stop the operation
immediately and contact your service provider/ local supplier and also intimate the failure code
indicated if any.
