⚫Make sure to prepare necessary safety measures before using samples that are toxic, radioactive or
contaminated with pathogenic micro-organisms at your own responsibility.
⚫If the instrument, rotor and/or accessories that has been contaminated by solutions with toxic,
radioactive or pathogenic materials, clean it according to the decontamination procedure that you are
specified.
⚫If you require services at site, please sterilize and decontaminate it in advance, and then notice the
service center involved in the details of the particular materials.
⚫Do not handle the power cord or turn on or off the POWER switch with wet hands to void electrical
shocks.
⚫For safety purposes, do not enter within 30cm around this centrifuge while it is in operation.
⚫While the rotor is rotating, never forcedly release the door lock.
⚫Unauthorized repairs, disassembly, and other services to the centrifuge except by our service center are
strictly prohibited.
CAUTION
⚫This centrifuge must be located on one firm and level table.
⚫Make sure the centrifuge is horizontal before running.
⚫Make sure the angle between the door and cover is greater than 70 degrees when open the door.
⚫Be careful not put your fingers or hands between the door and cover when the door off.
⚫Do not move or relocate this centrifuge while it is running.
⚫If fluid spills in the rotor chamber, please promptly clean and dry with a dry cloth to avoid sample
contamination.
⚫Ensure to remove any objects and fragments of the tubes dropped inside the rotor chamber before
running this centrifuge.
⚫Cautions on rotors
(1) Always check for corrosion and damages on the rotor surface before using it. Do not use the rotor if an
abnormality is found.
(2) Do not set the centrifuge speed beyond the allowable minimum speed of the rotor kits (rotor or
adapters). Make sure to run it below the allowable minimum speed.
(3) Do not exceed the allowable imbalance.
(4) Use the rotor and tubes within their actual capacities.
(5) If the rotor is attached with a lid, ensure it is tightened before operation.
⚫If any abnormal condition occurs during operation, please stop it immediately and contact our service
center. Notify the service center is a warning code if displayed.
⚫Vibrations are likely to damage the centrifuge, contact our service center if abnormality observed.

knob during acceleration, the centrifuge will start to decelerate and stop.
9. Maintenance
9.1 Cleaning
CAUTION
⚫If do not follow the recommended instructions for cleaning or disinfecting may damage the centrifuge.
（1）Centrifuge
⚫If the centrifuge is exposed to ultraviolet rays for a long time, the color of the doors may be changed or
the label may be came off. After using, cover the centrifuge with a piece of cloth to protect it from
direct exposure.
⚫If the centrifuge needs cleaning, clean it with a cloth or sponge moistened with a neutral detergent
solution.

USER MANUAL
17
⚫Sterilize the centrifuge by wiping with a cloth moistened with 70% ethanol solution.
（2）Rotor chamber
CAUTION
⚫Do not directly pour water, neutral detergent or disinfectant solution into the rotor chamber. Otherwise
fluids may leak into the drive units and cause corrosion or deterioration to the bearings.
⚫If the rotor chamber needs cleaning, clean with cloth or sponge moistened with a neutral detergent
solution. Sterilize the centrifuge by wiping with a cloth moistened with 70% ethanol solution.
（3）Drive shaft
⚫We recommend regular maintenance for drive shaft. You can wipe the drive shaft with soft cloth, and
then apply a thin coat of silicon grease.
（4）Door
⚫Clean and sterilize the door using the same method as the step (1) above.
（5）Rotor
⚫To prevent corrosion, remove the rotor from rotor chamber. If not in use for a lone term, then detach
the rotor lid and turn upside down to dry the tube holes and keep clean.
⚫For sample leaks in the rotor, rinse the rotor with water. Apply a thin coat of silicon grease to the rotor
when it is completely dry.
⚫The rotor should be regular maintenance, recommend to cleaning it each 3 months to ensure tube and
rotor holes keep clean, and then apply a thin coat of silicon grease.
(6) Drain (D3024R)
⚫The centrifuge is equipped with drain pipe for excess water. Drain off water when water is in drain
pipe.
