1.2 Safety precautions
Before using this product, be sure to read this manual to prevent malfunctions that may occur
during operation.
1. Always make sure that the device is fixed on a level surface that can withstand shaking and
weight of the device during operation and placed on a safe table
2. Do not move the product during operation, and leave a safe space within 30cm around the
centrifuge for user safety.
-At all times, the location of the device should have enough space around the device for
proper air circulation.
3. Always install the equipment in a place where temperature and humidity can be controlled.
4. Before connecting the power, the rated voltage should be checked.
5. Do not use unauthorized rotors or accessories.
6. Before using the device, make sure that the rotor and rotor lid are securely locked.
7. Check that the rotor is properly positioned on the motor shaft by turning it manually.
8. Do not stop the rotor by hand while the machine is in use.
9. Manual door opening is only used when rotation is completely stopped.
10. Permissible speeds and special specific gravity should not be used. If the density of the
whole sample is greater than 1.2 g/ml, the maximum rotational speed should be reduced
to avoid rotor failure.
11. When holding the sample, do not exceed 80% of the total volume of the tube. Otherwise,
the tube may break or the sample solution may flow.
12. In order to avoid unbalanced rotors, tubes should always be symmetrically filled with well-
balanced samples. (Please refer to 4.3 Sample Tube Loading) If necessary, they can be paired
using water to achieve balance.
13. The operating speed should not be higher than the respective guaranteed g values of the
centrifuge, rotor, bucket or adapter and sample tube. In particular, the guaranteed g value
of the sample tube should not be neglected.
14. The rotor should be cleaned and dried after every use for long life and safety.
15. Always disconnect the power supply during regular inspection and service to avoid electric

Refrigerated, Multi-purpose Centrifuges,1248R/1580R
AS : 02-3452-8966/070-8620-5350/[e-mail] | 6
shock.
16. Always centrifuge biological material and use a validated disinfection procedure.
17. Do not centrifuge flammable, toxic, radioactive, explosive, or corrosive substances.
18. If it is necessary to use toxic or radioactive substances or pathogenic microorganisms
belonging to WHO Risk Group Ⅱ, the national regulations of “Laboratory Bio-safety Manual”
must be observed.
19. This device is used in research use only and must be operated by a professional who has
received professional education, training and specialized skills for the using procedure.
1.3 Lifting and carrying
When moving the product, more than two people should
grab it from the front and back as shown in Figure.

3. Unpacking
1. Open the box and lift out the instrument carefully.
2. Two people should keep the system horizontally to lift up on the flat table.
3. To disassemble the Motor Protecting Devices, use the provided 6mm wrench and unscrew and
remove all 3 bolts. It is now ready for installation.
☞Place the instrument on the solid and flat table.
Motor Protecting Devices (3ea of screw bolts) are installed at the bottom of each instrument for
keeping the motor on place. As depicted in the following pictures, the length of one bolt in the
front bottoms is longer than the instrument’s feet for operator in order to recognize the wobbly
status. These bolts and nuts should be removed before the installation of the instrument.

[Automatic Rotor Recognition] System
When the rotor is installed and the lid is closed, it moves to the
main screen after the rotor scan process (Display screen: ROTOR
SCAN...). When the lid is opened, it moves to the main screen
without the rotor scan process. After entering the operation setting
value and touching the [Start] button, the operation starts after the
rotor scan process.
If the rotor is not installed, the “Error 9” will be appeared. This
message will be cleared after rotor installing and running.

4.1.2. Lid Release
1. When the lid is closed, touch the [LID] button to open the lid.
▷Close the lid until hearing clank shut.
▷When the lid is opened, the lid LED
turns on.
▷When the lid is closed, the lid LED turns
off.
√The lid will not open if the centrifuge is running.
√If the lid is opened, the centrifuge will not start even with pressing [START] button.
√To maintain the temperature of the sample, the lid does not open automatically after
the operation is over.
√ Power failure : If the lid does not open due to a power failure during operation, it
can be opened manually. Please refer to ‘5.10. Manual Lid-lock release’. But DO NOT
use the Manual Lid-lock release as regular procedure to open the centrifuge. Use it
only if a malfunction or power failure occurs and only when you have made sure that
the rotor has stopped spinning.
[Motorized Lid Closure] system
The lid lock system of this centrifuge is locked with a soft touch, so do not excessively
force to close.
4.2. Install and Remove a Rotor
Before installing a rotor
-If necessary, remove any dust, foreign objects or residue from the chamber.
-Wipe the motor shaft and rotor hub from the bottom side of the rotor with a clean

3. To install the rotor, hold the rotor well with one
hand and rotate the Rotor Locking Tool
clockwise until tightly clamped.
4. Make sure that the rotor is properly installed by
lifting it slightly. If the rotor can be pulled up,
then it must be re-clamped to the motor shaft.
5. Make sure that a full complement of buckets is
installed before operating the rotor.
6. Check that the rotor and buckets spin freely by
turning it manually. If not, please apply the
Lubricant (grease) at the bolts of swing out
rotors.
Remove
1. Remove samples, adapters or buckets.
2. Insert the Rotor Locking Tool into the center hole of the rotor.
3. To remove the rotor, hold the rotor well with one hand and rotate the Rotor Locking
Tool counterclockwise.
4. Grasp the rotor with both hands.
5. Pull the rotor directly upwards and away from the motor shaft with both hands.

rotor.
3. To install the rotor, hold the rotor well with one hand and
rotate the Rotor Locking Tool clockwise until tightly clamped.
4. Make sure that the rotor is properly installed by lifting it
slightly. If the rotor can be pulled up, then it must be re-
clamped to the motor shaft.
5. Put the rotor lid on the rotor. Make sure the rotor lid is put
centered on the rotor.
6. Turn the rotor lid knob clockwise to close the lid.
Remove
1. Remove samples, adapters.
2. Turn the rotor lid knob counterclockwise.
3. Insert the Rotor Locking Tool into the center hole of the rotor.
4. To remove the rotor, hold the rotor well with one hand and rotate the Rotor Locking
Tool counterclockwise.
5. Grasp the rotor with both hands.
6. Pull the rotor directly upwards and away from the motor shaft with both hands. Make
sure do not tilt the rotor while lifting it.

If you operate a fixed angle rotor, make sure that the rotor lid is properly locked. If
not, it may occur very loud noise and serious damage.
4.3. Sample Tube Loading
1. Before loading sample tubes, check the water drop or any dirt in the rotor hole or
adaptor, bucket.
▷If there is any foreign matter or moisture, remove it with soft dry cloth.
2. Load the compartments evenly. Balance opposite loads.
▷Tubes should be placed in the rotor with same amount of samples at symmetrical
positions. (Refer to below examples)
▷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 damage
the instrument.
▷When using swing out rotors, weigh the bucket content (adapter and tube). Make
sure do not exceed the maximum compartment load nor the weight difference limit
for adjacent buckets if there is one for the rotor.
Make sure that the tubes and bottles used in the centrifuge are
√fit in the rotor and the tubes or bottles do not touch the rotor
lid or bucket caps.
√rated to or above the selected RCF to be spun at
√used at their minimum fill volume and not above their
maximum fill volume
√undamaged and not used above their design life (age
or number of runs)

Caution!
Incorrect loading can lead to damage. Always load the sample tubes symmetrically to avoid
imbalance, noisy spinning and possible damage. A full complement of buckets needs to be
installed before operating swing out rotor.
->For safety, the “Imbalance Cut Off” function will be occurred, if there is imbalance of loading
tubes (Error 8, Imbalance error). Please refer to 7. Trouble Shooting.

4.4. Drain Hole
This centrifuge is equipped with a drain hole which allows
water or condensate to be discharged from inside the
chamber. Before the centrifuge starts, check if the drain hole
on the left side of the instrument is completely tightened. If
not, refrigeration efficiency could be getting lowered.
