generated or chemicals are stored.
⚫Make sure to prepare necessary safely measures before using samples that are
toxic, radioactive or contaminated with pathogenic micro-organisms.
⚫If the instrument, the 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 specified.
⚫If the contaminated equipment requires service of Dynamica or authorized agency
of Dynamica, either at the customer’s site, Dynamica or at the agent facilities, sterilize
and decontaminate it in advance. Make sure to notify the service representatives of the
use of such materials.

iv
centrifuge when it is operating.
⚫Never forcedly release the door lock while the rotor is rotating.
Unauthorized repairs, disassembly, and other services applied to the centrifuge are
strictly prohibited.
CAUTION:
⚫The centrifuge must be located on the firm and level table.
⚫Be careful not to get your fingers or hands caught between the door hook and the
table when closing the door.
⚫When opening the door, make sure the angle between door and the shell is more
than 70 degree.
⚫Do not move or relocate this centrifuge while the rotor is rotating.
⚫If there is liquid in the chamber, towel off it immediately to avoid contaminating the

⚫Cautions on rotors:
1）Always check for corrosion and damages on the rotor surface before using it. Do
not use the rotor or bucket if such abnormality is found.
2）Do not run this centrifuge over the allowable maximum speed of the rotor, buckets,
and adapters. If their maximum speeds vary, run it at the lowest maximum speed
among them.
3）Do not exceed the allowable imbalance.
4）Make sure the tubes and bottles within their actual capacities.
5）Make sure all the buckets are the same type at all times.
6）If the rotor is provided with a cover, make sure it is tightly rotated on the rotor
before the operation.
7）Use recommended rotors only.
⚫If any abnormal condition occurs during operation, stop it immediately and contact
our service representative. Notify the service representative the error code.
⚫Earthquakes may cause damage to the centrifuge. Contact our service
representative if abnormality observed.

3 Installation
This section describes the instructions that you should abide by when installing the
centrifuge to ensure your safety and the optimum performance.
WARNING:
•This centrifuge may be damaged if it is connected to an improper power source.
•Check if the power source meets the requirements.
•Must take out rotor before moving the centrifuge.
•When transporting the machine, need to use trolley or need 2persons to move the
machine together.
3.1 Location
1）Locate this centrifuge on a firm and level table, ensure the four feet of this centrifuge
stand on the table firmly.Avoid installing on the slippery table that conveys vibration.
2）Ideal environment temperature is 20℃±5℃. Temperature should not be over 30℃.
Avoid direct sunlight to the instrument.
3）Keep clearances of 10cm on both sides of the centrifuge and 30cm behind it to ensure
its cooling efficiency.
4）Do not install near by a heat-generating device or waterworks from where may drip or
splash. Such location may cause sample temperature fluctuation or malfunction of the
centrifuge.
WARNING: Users or any hazardous are recommend keeping 30cm away from the
centrifuge when it is running.
3.2 Connection of the power cord and grounding
WARNING:
•Do not touch the power cord with wet hands to avoid electrical shocks.
•This centrifuge must be properly earthed.
1) This centrifuge is equipped with a 3P flat plug. Grounding can be done by plugging the
3P plug into the outlet.

6 Preparation of Rotor
WARNING:
•This centrifuge is not explosion-proof. Never use explosive or flammable samples.
•There is restriction on the usage of biological samples and radioactive substances
that require biological isolation such as pathogens and recombinant DNA for safety
purposes. User must prepare necessary safety measures before treating with samples
containing such substances.
1) Prepare the sample
2) Put the sample into tubes or bottles
CAUTION: Sample may leak from the gap between the bottle and its cap if the
bottle is fully filled up.
◼Do not exceed the capacity specified in the instruction manual.
3) Balance the centrifuge tubes or bottles
CAUTION: There are some cases where samples of different composition due in
different precipitation levels by centrifugation even if they are equal in volume, and such
operation may increase the level of imbalance. Properly arrange the tubes or bottles so
that the same sample is placed symmetrically.
◼See Table 6.1 for imbalance tolerance of each rotor.
◼Although this centrifuge can accept sample balancing by eye, we recommend that
you use this centrifuge in a well-balanced condition to prolong its life expectancy.
◼Never intentionally run the centrifuge under unbalanced condition even though the
allowable imbalance tolerance is not exceeded.
4) Inspect the rotor
CAUTION:
⚫If any abnormality such as corrosion or scratches is found, stop using the rotor and
contact our service representative.
⚫Only use the rotors we recommended.
◼Check whether the rotor and the bucket have corrosion or scratch before use.
◼Check whether the swinging bucket rotor swings smoothly by slightly spinning the
rotor manually. Perform periodic maintenance on the rotor.
5) Set balanced tubes or bottles symmetrically on the rotor or rotor frame

12
CAUTION: Make sure that the cover is put on the rotor and fixed securely.
Otherwise, the rotor or its cover may be dropped off while the instrument is running.
That might damage the centrifuge or the rotor.
6) Confirm the ID code of the rotor
◼This instrument can identify rotors automatically. There is magnetic steel embedded
at the bottom of rotor.
◼Each rotor is assigned with an ID code. After the rotor is identified, the optimum
temperature can be automatically controlled, and the function of over-speed protection
and the speed/RCF display can be realized.
◼The list of available rotor’s ID code, see Table 6.1.

7 Operation
WARNING:
•Do not push or lean the machine when it is running.
•Do not run the centrifuge with fragments of tubes or dew drops left in the rotor
chamber. Those matters may get mixed with sample or may cause the rise of the rotor
retention temperature. Always keep the rotor chamber clean.
•If the centrifuge makes abnormal noise during its operation, stop it immediately
and contact our service representative. Notify the error code if displayed.
7.1 Normal Operation
1) Turn on the power switch.
◼The LCD screen displays a welcome interface and shows the accumulative total
running time, in the meantime, this centrifuge starts a self-checking process for
preparation. (see Figure 7-1).
Initializing…
V X.XX
Figure 7-1 Initialization interface
◼If the self-checking fails, the screen displays an error code on its right bottom corner.
Please refer the error code in the table 11-1.
NOTE: When the power is turned on, this centrifuge will take 7 seconds to self-check.
During this time, the centrifuge will have no response to the buttons.
◼This centrifuge will move to a preparing screen after passing the self-checking step,
and display the running parameters of the last time. For example, the Figure 7-2 shows
that the speed was set to be 14000rpm, the running time was 2 hours and 30 minutes, the
acceleration rate was 9, the deceleration rate was 7, the rotor ID was 19, and the program
group number was 9.
Figure 7-2 is only an example. User’s setting parameters and running parameters may be
different from that in the figure.
