4. Setup
- Prepare Tubing: Connect appropriate tubing (e.g., 3mm ID x 5mm OD) to the inlet and outlet ports of the pump head. Ensure connections are secure to prevent leaks.
- Mounting: Secure the pump in a stable position using the integrated mounting points.
- Power Connection: Connect the pump to a stable DC 12V power source.
- Connect the positive (+) terminal of the power supply to the positive wire of the pump.
- Connect the negative (-) terminal of the power supply to the negative wire of the pump.
- Note: Reversing the polarity will reverse the direction of liquid flow.
- Initial Test: Before connecting to your main system, perform a brief test with water to ensure proper operation and check for any leaks.

5. Operating Instructions
Once the pump is properly set up and connected to a 12V DC power source, it will begin to operate. The flow rate is determined by the internal motor speed and the dimensions of the pump tube used.
- Starting the Pump: Apply 12V DC power to the pump.
- Stopping the Pump: Disconnect the 12V DC power supply.
- Changing Flow Direction: Reverse the polarity of the 12V DC power connection to change the direction of liquid flow through the pump.
- Flow Rate Control: The pump operates at a fixed motor speed. To adjust flow rate, you may need to use a variable voltage power supply (within the 12V DC limit) or select different tubing sizes as indicated in the specifications.
6. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your peristaltic pump. The snap-type design facilitates easy access for cleaning and tube replacement.
- Pump Tube Replacement:
- Disconnect power from the pump.
- Gently press the pump head to release the snap mechanism.
- Carefully remove the old pump tube.
- Insert a new, compatible pump tube, ensuring it is correctly seated within the pump head.
- Snap the pump head back into place until it is secure.
- Cleaning:
- For general cleaning, wipe the exterior of the pump with a damp cloth.
- If the pump head or rollers require cleaning, disassemble the pump head as described above and clean components with a mild detergent and water. Ensure all parts are dry before reassembly.
- Avoid using harsh chemicals or abrasive materials that could damage the pump.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power or incorrect voltage. | Verify the 12V DC power supply is connected correctly and is active. Check wiring for loose connections. |
| No liquid flow | Blocked tubing, air in the line, or incorrect tube installation. | Check tubing for kinks or blockages. Ensure tubing is properly seated in the pump head. Prime the pump if necessary by manually drawing liquid through the inlet. |
| Inconsistent flow rate | Air bubbles, worn pump tube, or external pressure variations. | Check for air leaks in the tubing system. Replace the pump tube if it appears worn or damaged. Ensure consistent liquid supply. |
| Liquid leaks from pump head | Improperly installed pump tube or damaged tube. | Ensure the pump tube is correctly installed and the pump head is securely snapped into place. Replace the pump tube if it is damaged. |
