Safety Reminder
Symbol is the general internationally safety sign, please read carefully and fully
understand the following safety precautions.
⚫Read all safety Warnings and Cautions in this manual carefully.
⚫Safety messages are labeled as followings. The safety symbol is in combination
with words of “WARNING” and “CAUTION” to notify users the potential danger; The
definitions of this two combination are as follows:
WARNING: Personal dangerousness
Warning notes indicate any condition or practice, which if not strictly observed, could
result in personal injury or possible death.
CAUTION: Instrument damage
Caution notes indicate any condition or practice, which if not strictly observed or
remedied, could result in damage or destruction of the equipment.
NOTE: Notes indicate an area or subject of special merit, emphasizing either the
product’s capability or common errors in operation or maintenance.
⚫Do not use the centrifuge in the way which does not mention on this manual, Please
contact Dynamica technician if you have any question.
WARNING:
⚫This centrifuge is not explosion-proof. Never use explosive or flammable samples.
⚫Do not install the centrifuge in or near places where inflammable gases are
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.
⚫Do not touch the power cord or switch with wet hands to avoid electrical shocks.
⚫Users or any hazardous materials are recommended to keep 30cm away from the

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
sample.
⚫Keep the chamber clean and remove any objects before running the instrument.
⚫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. Before moving the
centrifuge, the rotor must be removed.
WARNING:
•This centrifuge may be damaged if it is connected to an improper power source.
•Check if the power source meets the requirements.
3.1 Location
1）Locate the centrifuge on a firm and level table, ensure the feet of the centrifuge stand
on the table firmly. Avoid installing on the slippery table-board 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 10 cm on both sides and 30cm behind it to ensure its cooling
efficiency. After installing, this distance should be marked around the centrifuge to ensure
its cooling efficiency.
4）Do not install nearby a heat-generating device or waterworks from where water may
drip or splash. Such location may cause sample temperature fluctuation or malfunction of
the centrifuge.
WARNING: No any hazardous materials are within 30cm around the centrifuge to
avoid leaking due to heavy vibration of the centrifuge.
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 grounded.
1) This centrifuge is equipped with a 3P flat plug. Grounding can be done by plugging the
3P plug into the outlet.
2) The outlet must have bigger current capacity than 10Aand its earth terminal is installed
properly.
