2-1. Safety
Centrifuge containing the high speed rotating part is dangerous. Follow
the instruction described in this manual to avoid breakage, trouble, injury.
1) Centrifuge must be placed the horizontally flat level, In the case of tilted
shaft of rotating big vibration occurs.
2) Check the voltage before connecting power, the improper volt may cause
the damage.
3) Use only the rotor, parts and accessories supplied by the maker, which is
not responsible for any damage caused by improper parts not
recommended by the maker.
4) Ascertain the material property completely and pre-arrange safety measure
in the case of handling pathogenic, toxic, radioactive material.
5) As Centrifuge is contaminated by pathogenic, toxic, radioactive material,
contaminant is to be cleared and ventilated and the isolation is needed.
6) Volatile and explosive material should not be treated by Centrifuge.
7) Don’t operate over the approved maximum rpm of rotor.
8) Don’t diminish and stop the rotating rotor with hand.
9) Rotor must be operated after symmetrical balance work of weight
10) Rotor must be fixed to the rotating shaft exactly and lid also fixed
completely. If not, the lid may open during operation.
11) Repairing and maintenance not mentioned on this manual must be
handled by the technician with the proper curriculum (in this case the
contaminant is to be cleared)
12) In order to keep the best condition and operation of long term the
chamber of rotor must be kept dry.
13) The chemical corrosion of rotor contacting strong acid, alkaline agent of
Cesium, silver, chlorine base should be avoided carefully.

2-2. Location of placement
To be installed on the rigid and flat level;
The rotation of heavy rotor in the long period on the inclined level may cause
the deformation of rotating shaft.
Smooth air ventilation;
Centrifuge needs 30cm of vacant space of front & rear and right & left. An airway
should not be covered by the another instrument or fabric, avoid the place of
heavy dust.
Constant temp. & humidity;
The sensitive electronic controller is affected by ambient temp. and humidity.
Avoid direct sunray and heater and keep the constant temp. & humidity.
No erosive gas;
Avoid the place of erosive gas. Contacting sulfurous acid/ chlorine gas erodes
Rotor & shaft and damage metal parts.
Leveling;
Shaft should be vertical exactly and Centrifuge is to be placed horizontally
with flatness measuring device.

2-3. Check list
Don’t open door manually during rotating rotor, don’t use emergency door
open device except the emergent case.
Rotating speed of rotor should not exceed the allowed max speed. The rotor is
designed to endure only with the allowed influencing power. If RCF exceeds the
allowed tensile strength, the rotor shall break or be deformed.
Circuit breaker;
Lightning or over voltage activates circuit breaker, cut off fuse and power supply
to protect main body.
Door lock device;
Door sensor lets rotor stop in the case of open door and Centrifuge doesn’t
operate at the status of door open.
Auto door lock device doesn’t allow door open during operation without
manual opening of door.
Abnormal vibration;
As rotating rotor vibrates seriously over the limited standard off balance and
Accordingly motor shakes, the relevant sensor detects the abnormality and the
rotation stops according to the pre-arranged deceleration interval.
This safety device avoid the unexpected danger & damage during operater’s
absence with the continuous operation of Centrifuge.

2-4. Electrical requirements
Ascertain the rated voltage on the label of Centrifuge. Unclear power supply of
using should be checked again with the local electric power supplier or our A/S
center.
Warning ; Centrifuge must connect to ground.
- Centrifuge contains plug with earth pin which can be inserted into the grounded
receptacle. Using receptacle without earth must be replaced to grounded
receptacle, during this work user must be careful not to get electric shock with
the assistance of electrician. Avoid the receptacle without grounding.
- In the case of error the emergency switch is located at the exit door side or
outside of laboratory, a remote area from Centrifuge to cut off power supply.
- The safety distance 30 cm from Centrifuge must be kept and any breakable
unit is moved away according to IEC61010-2-020 regulation.

3-3 Rotor
- Wipe the motor shaft and hole of rotor with fabric before installation
- As tighten rotor with motor shaft, temp. of rotor & motor should be
10~30℃
- Put rotor on the motor shaft tighten clockwise with hexagonal wrench
In the case of release screw wrench to the counter direction
1) Weight loading on rotor
- Put tubes symmetrically on rotor, only recommended tubes are workable.
- The weight difference between sample tubes must be minimized to
diminish noise and extend durability
- Locate tubes of same type for the stability of Centrifuge
-
* Use only rotor/tube/adapter recommended by the manufacturer
* Check the proper tube-rack insert and smooth motion
* Don’t use the eroded motor of visibly mechanical failure
2) Tube arrangement
Same volume of sample must be put in tubes after precise measuring and
arrange the symmetrical insert to rotor. In the case of difference per each
symmetrically arranged samples heavy vibration occurs, which may
damage the shaft.
Despite the same q’nty of tubes the location of tubes may be
dissymmetrical. Adapters’ tube location facing each other also must be
checked the proper location. In the case of dissymmetrical location caused
by the variation of tube q’nty newly added tube may make the
equilibrium.
Use a scale to minimize the weight difference of sample tubes.

<1> Prepare the parts. (Rotor, Wrench) <2> Remove the buffer under the motor
<3> Wipe the motor shaft and hole of rotor with
fabric before installation. Attach the rotor to the shaft
of the motor and turn the wrench clockwise to
tighten it completely.
*Be careful of the direction of the rotor.

In the case of spin down lean tubes’ lids against the edge of rotor and
Ascertain the sameness of tubes and close the rotor lid. This instruction
must be applicable for using tubes provided by the kit manufacturer.
Swing bucket rotor
Check the internal cleanness of bucket and wipe out the foreign material
with dry fabric. In the case of two buckets check the hanging status
on rotor and do swing test manually.
Rotor must be inserted with the symmetrical location of adapter, plate,
tubes. In the case of different weight of sample of symmetrically located
the heavy vibration by unbalance rotation may result in the damage of
rotor & shaft.

failure.
1) Off power switch, await till rotor stops.
2) Insert 5mm T wrench into the hole on the right flank side and turn
clockwise to open door.
4-1. Cleaning
1) Exterior
- Clean the surface with soft & dry fabric. In the case of heavy
contamination wipe out with soft soapy cloth and use dry cloth to
remove water.
-Don’t use chemicals like alcohol, benzene, thinner which may damage
Centrifuge. Use neutral detergent of sound quality.
-Don’t make any scratch with hard & sharp material like metal brush
and move cautiously to avoid rust.
- Remove rust from humidity for long period with the netural detergent
and wipe out with dry fabric.

2) Interior
- Remove and clean periodically frost of rotor & chamber for the efficient
cooling.
- Off power switch and remove frost with dry cloth
- Clean the chamber with soaked sponge or cloth and dry completely after
removing frost.
3) Shaft
- Shaft must be kept clean, the unstable rotation by contaminant of shaft
causes imbalance.
- Take rotor out of shaft and clean with dry fabric to remove water after
operation and keep dry.
- Weight of rotor causes deformation of shaft, which must be separated
and cleaned and kept upside down.
-As rotor tightly sticks with shaft, don’t remove forcibly, only use the
specialized rotor removing tool.
4) Rotor
①Corrosion & surface treatment
- Acid or basic agent causes damage. Imbalance of rotor weight by
corrosion incurs heavy vibration & noise, eventually the physical damage.
- Anti-corrosive rotor may be affected by humidity, salt content and
impurity in air.
- Rotor is resistant to neutral aqueous solution like carbonate, chromate,
acetate and sulfide, but not to chloride agent. Also corrosion gets faster
By increase of hydrogen ion content and eroded by sulfuric and
phosphoric and faster in hydraulic acid.
②Maintenance
- Cleaning; remove sample in tube with soft fabric soaked with warm water
avoid scratch on the specially treated rotor surface.
- Drying; dry narrow groove of rotor, more efficiently with hair-drier.
- Keeping; Clean & dry place, separate lid of angle and keep upside down.
③Sterilization of rotor
Every rotor, lid, bucket adapter can be sterilized at 121℃for 20 min.

4-2. Maintenance
1) Check & clean rotor frequently
2) General check points
Shaft & hub; Don’t separate hub and bent shaft, check abrasion.
Motor bearing; Check noise and the smooth rotation
Control board; Check bolt connection and functioning
Power supply; Check whether connection is loosened.
Rotor; Check crack, cleanness, abrasion.
3) RPM
Install rotor and set RPM, count the actual RPM with tachometer.
4) Time
Set 10 min and count the actual time with stop watch.
5) Detecting Imbalance
In the case of imbalanced rotor, check whether the lamp of imbalance
is on with alarm sound.
6) Door locking device
Door should not open during operation.
7) Disposal
Centrifuge should not be scraped as the waste of house hold and
only disposed according to the local environmental regulation.
