4. Setup and Installation

1. Unpacking: Carefully remove the centrifuge from its packaging. Inspect for any visible damage. Retain packaging for future transport or storage.
2. Placement: Place the centrifuge on a sturdy, level, and vibration-free workbench. Ensure there is adequate space (at least 10 cm) around the unit for ventilation.
3. Power Connection: Connect the power cord to the centrifuge's power inlet and then to a grounded electrical outlet (USA Plug). Ensure the voltage matches the instrument's requirements.
4. Rotor Installation:
   • Open the centrifuge lid.
   • Carefully place the As24-2 Aluminum Alloy Rotor onto the motor shaft, ensuring it sits firmly.
   • Secure the rotor using the provided rotor nut/tool, tightening it clockwise until snug. Do not overtighten.
5. Initial Check: Close the lid. Power on the unit using the main power switch. The display should illuminate.

5. Operating Instructions

5.1. Loading Samples

1. Ensure the rotor is clean and dry.
2. Load samples into the rotor tubes. Always balance the rotor by placing tubes of equal weight directly opposite each other. Uneven loading can cause vibration and damage.
3. Close the rotor lid (if applicable) and then close the centrifuge main lid securely.

5.2. Setting Parameters

Use the control panel buttons and knob to set the desired parameters:

• Speed (RPM/RCF): Adjust the rotational speed.
• Time: Set the centrifugation duration.
• Temperature: Set the desired temperature for refrigeration. The pre-cooling function will activate to reach this temperature quickly.
• Acceleration/Deceleration: Select appropriate ramp rates (if available).

5.3. Starting and Stopping

1. Press the START button to begin the centrifugation cycle.
2. The display will show the current status (e.g., actual speed, remaining time, temperature).
3. To stop the cycle prematurely, press the STOP button.
4. Once the cycle is complete and the rotor has come to a complete stop, the lid will unlock automatically or can be opened manually.
5. Carefully remove your samples.

6. Maintenance and Care

6.1. Cleaning

• Exterior: Wipe the exterior surfaces with a soft cloth dampened with mild detergent or disinfectant. Avoid abrasive cleaners.
• Rotor Chamber: Clean the rotor chamber regularly to prevent accumulation of dust or spills. Use a soft cloth and mild cleaning solution. Ensure it is dry before next use.
• Rotor: Clean the rotor and accessories after each use. Autoclave or sterilize as per laboratory protocols and manufacturer guidelines.

6.2. General Care

• Regularly inspect the power cord for damage.
• Check the rotor and rotor chamber for any signs of corrosion or wear.
• Ensure proper ventilation is maintained around the unit.
• Store the centrifuge in a dry, dust-free environment when not in use for extended periods.
