Safety Reminder
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 safety 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 services 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 handle the power cord or turn on or off the POWER switch with wet hands
to avoid electrical shocks.
Users or any hazardous materials are recommended to keep 30cm away from the
centrifuge when it is operating.
While the rotor is rotating, never override the door lock.
Unauthorized repairs, disassembly, and other services maintenance applied to the
centrifuge except by our service personnel are strictly prohibited。
When this product encounters disturbance of severe electrostatic discharge or
surge, it might have some degradation of performance like resetting or random errors
and so on. The operator should restart the equipment to recover the normal operation.
This is a class A product. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.

iv
CAUTION:
The centrifuge must be located on a firm and level table.
Be careful not to get your finger or hands caught between the door hook and the
table when closing the door.
Do not move or relocate this centrifuge while the rotor is rotating.
If dew drops found in the rotor chamber, drain out the fluid through the drain hole to
prevent the sample to get mixed up with them and prevent them from leaking into the
drive unit.
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 tolerance.
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. 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 specified on the plate at the
rear of this centrifuge.
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 otherwise the centrifuge will
have a bigger vibration.
2）Ideal environment temperature is 20℃±5℃. Temperature should not be over 30℃.
Avoid direct sunlight to the instrument.
3）Keep 300 mm distance on both sides and back of this centrifuge. This is a safe
distance of the centrifuge. After installing, this distance should be marked around the
centrifuge to ensure its cooling efficiency.
4）Make sure there is no water or heat around the centrifuge. Otherwise, it will result in
sample’s temperature increasing or malfunction of 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, 1Pof 3P is for grounding. Grounding can
be done by plugging the 3P plug into the outlet.
2) The outlet must have bigger current capacity than 10A (for 220V instrument) or 25A(for
110V instrument), and its earth terminal is installed properly.

3.3 Horizon adjustment
1) Turn on the power switch. After initialization, open the cover and turn off the power
switch. If the machine is not connected to the power supply, user may refer to the method
explained in section 12.1, and then open the cover.
2) Put the Level on the axis crown (see the following figure), and revolve the axis crown
for at least one circle and observe whether the air bubble is always in the central of the
level to check whether the centrifuge is horizontal.
3) If the centrifuge is not horizontal, adjust the four support feet under the bottom plate
(see the following figure) until the air bubble stay in the central of level. During adjustment,
user should rotate the axis crown continuously and check the position of air bubble. To
adjust the level, unscrew anticlockwise the lock screws to loosen them. Turn the support
feet clockwise to lower the centrifuge, vice verse. (Use the wrench in the accessory box if
needed.)
4) When the instrument is horizontal, make sure four support feet are firmly standing on
the table. Any suspended support foot is not allowed. Slightly press the top of the
Adjustable support feet
