⚫Do not place dangerous materials within 30cm of the centrifuge.
⚫Prepare all necessary safety measures before using samples that are toxic, radioactive or contaminated
with pathogenic micro-organisms. Use of these is at your own responsibility.
⚫If the centrifuge, rotor and accessories that have been contaminated by solutions with toxic,
radioactive or pathogenic materials, clean it according to the decontamination procedure as specified.
⚫If you require service at site, please sterilize and decontaminate the centrifuge in advance, and then
notify the service center the details of the materials and procedure.
⚫To avoid electrical shocks, insure hands are dry before handling the power cord or turning on/off the
power switch.
⚫For safety purposes, do not enter within 30cm around this centrifuge when it is in operation.
⚫While the rotor is rotating, never release the door lock.
⚫Unauthorized repairs, disassembly, or modifying the centrifuge except by our service center are
strictly prohibited.
CAUTION
⚫This centrifuge must be located on a firm and level table.
⚫Make sure the centrifuge is horizontal before running.
⚫Do not move or relocate the centrifuge when it is running.
⚫If fluid spills in the rotor chamber, please promptly clean and dry with a dry cloth to avoid sample
contamination.
⚫Ensure to remove any objects and fragments of the tubes dropped inside the rotor chamber before
running the centrifuge.
⚫Cautions with rotor
(1) Always check for corrosion and damage on the rotor surface before using it. Do not use the rotor
if an abnormality is found.
(2) Do not set the speed beyond the allowable minimum speed of the rotor kits (rotor and adapters).
Make sure to run it below the allowable maximum speed.
(3) Do not exceed the allowable imbalance.
(4) Use the rotor and tubes within their actual capacities.
If any abnormal condition occurs during operation, please stop it immediately and contact our
service center. Notify the service center is a warning code if displayed.
⚫Vibrations are likely to damage the centrifuge, contact our service center if abnormality observed.

5.Installation
This section describes the instructions that you should abide when install the centrifuge to ensure your
safety and the optimum performance. Before moving the centrifuge, the rotor must be removed.
WARNING
⚫Improper power supply may damage centrifuge.
⚫Make sure the power source conforms to the required power supply before connecting.
5.1 Location
（1）Place this centrifuge on a firm、flat and level surface, ensure the four feet of this centrifuge stand on
the counter firmly. Avoid installing on a slippery surface or surface prone to vibration.
（2）Ideal ambient temperature is 20℃±5 ℃, avoid placing the centrifuge in direct sunlight if temperature
exceeds 30℃.
（3）Keep clear of the centrifuge at least 10cm on both sides and at least 30cm behind it to guarantee the
cooling efficiency.
（4）Keep away from heat or water to avoid sample temperature issues or centrifuge failures.
5.2 Connection of the power cord and grounding
WARNING
⚫To avoid electrical shocks, ensure your hands are dry when touching the power cord.
⚫This centrifuge must be grounded properly.
An minimum 10A outlet providing a sufficient ground is required, and this must meet local safety
requirements.

⚫Do not exceed the actual capacity allowed in the user manual.
8.3 Keep the tubes balanced
⚫Although the centrifuge can accept sample balancing by eye, we recommend that you keep this
centrifuge in a well-balanced condition to extend its life expectancy.
⚫Never intentionally run the centrifuge under an unbalanced condition even though the allowable
imbalance is not exceeded.

service center.
⚫Only manufacturer’s rotors must be used with the unit.
8.5 Symmetrically load centrifuge tubes into rotor
CAUTION
⚫Make sure the rotor lid is securely fixed on the rotor, as well as the rotor and shaft are tightened.
Otherwise, the rotor may be moved off while rotating and cause damage to the centrifuge and rotor.
⚫Firmly tighten the rotor lid to the rotor.
9. Operation
9.1 Normal operation
Turn on the power switch, centrifuge will display the running interface last time after passing the
self-diagnostic checks.
CAUTION
⚫Do not overload samples into the centrifuge which will cause leaking.
CAUTION
⚫Do not push or lean against the centrifuge while it is running.
⚫Do not run the centrifuge when fragments or sample solutions are left in the centrifuge chamber.
Always keep the centrifugal chamber clean.
⚫If the centrifuge makes strange noise during operation, stop it immediately and contact our service
center. Notify them of the warning code if displayed.
