1. The centrifuge should be placed on a flat and sturdy ground or experimental platform, and should not be tilted. The voltage of the external power supply system should match and require a good grounding wire. Before starting up, check whether there are any foreign objects falling into the machine cavity and whether the rotor is fixed properly.

2. When centrifuging volatile or corrosive liquids, a covered centrifuge tube should be used and the liquid should not leak outside to prevent erosion of the machine chamber or accidents. If there is any leakage, it needs to be cleaned up in a timely manner.

3. Do not exceed the maximum speed of the rotor during operation. The maximum speed and capacity of the rotor are related, especially for high-speed centrifuges. Please carefully read the instructions before use.

4. After using the freeze centrifuge, the water vapor inside the chamber should be wiped dry. To prevent water vapor from entering the motor and causing malfunctions.

5. If the user's voltage is unstable, it is recommended to equip the machine with a fully automatic electronic AC voltage stabilizer to avoid damaging the centrifuge; The centrifuge should be installed on a sturdy, stable, and level ground, with a certain amount of space around the chassis and good ventilation maintained.

6. The time interval between each shutdown (power off) and restart of the refrigeration machine model should not be less than 5 minutes to avoid compressor blockage and damage.

7. The centrifuge casing should be kept clean and dry, and can be cleaned with a dry/wet cloth. Neutral detergents can be used, but acidic/alkaline detergents cannot be used.

8. The centrifuge chamber should be kept clean and dry. When there are foreign objects in the centrifuge chamber, please use a cloth or tweezers to remove the debris from the chamber. You can use a dry/wet cloth to scrub, and if necessary, use a neutral detergent to clean, then rinse with water and wipe dry. But acidic/alkaline solvents that corrode materials and chlorine containing detergents and disinfectants cannot be used. During normal operation, condensation may occur due to the contact between air and the low-temperature centrifugal chamber wall. It should be wiped dry in a timely manner to prevent frosting. If frosting occurs, the rotor can be removed, the centrifugal chamber door can be closed, and the temperature set to 25 ℃. When the temperature reaches 20 ℃, the chamber door can be opened, the centrifugal chamber wall can be wiped dry, the rotor can be installed, and the desired temperature can be set.

9. After each use of the centrifuge, the door cover should be opened, the condensed water wiped off, and then naturally dried; Before and after centrifugation, the rotor must be gently lowered or lifted vertically to avoid colliding with the shaft and the rotor itself.

10. Rubber sealing rings are installed at the contact between the upper part of the centrifuge chamber and the door cover, as well as at the rotor seat and the bottom of the centrifuge chamber. Over time, deformation should be regularly observed to prevent external heat from seeping in and affecting the centrifugation results due to poor temperature control. If deformation or aging is found, it should be replaced in a timely manner.

11. Regularly use compressed air (vacuum cleaner) to remove dust from the ventilation windows and condenser located at the front and rear of the centrifuge, ensuring ventilation and heat transfer efficiency of the condenser, and improving cooling and heating effects.

12. When the centrifuge is not in use for a long time, the rotor body should be removed and rust proof oil should be applied to the rotor seat (or drive shaft) to prevent poor fit between the rotor seat and the rotor body after rusting, which may affect the balance effect of the instrument during operation. If necessary, desiccants can be placed in the centrifuge chamber to absorb moisture and prevent rusting of the rotor seat (or drive shaft).

13. The pneumatic support rod of the door cover should be checked regularly to ensure that it works properly and the connection is intact. If there are cracks or other problems, please replace it immediately.

14. Special safety measures must be taken when centrifuging toxic, radioactive, or contaminated samples.

15. Attention to safety precautions for operators: The rotor should be fixed in the accurate position, the fixing screws should be tightened, and the rotor and other accessories should be checked for cracks and corrosion, as well as the contact of the ground wire.
