Setup and Installation

- Identify Part: Determine which part of your breast pump needs replacement (e.g., duckbill valve, diaphragm, tubing).
- Remove Old Part: Gently detach the worn or damaged part from your breast pump. Be careful not to damage other components.
- Install New Part:
- Duckbill Valve: Carefully push the new duckbill valve onto its designated connector on the pump body. Ensure it is seated firmly and flat for proper suction.
- Diaphragm: Place the silicone diaphragm onto the pump body, ensuring the edges are securely sealed all around. A proper seal is crucial for maintaining vacuum.

Maintenance and Care
Cleaning
- Immediately After Use: Disassemble all parts that come into contact with breast milk.
- Washing: Wash parts in warm water with mild dish soap. Use a soft brush for hard-to-reach areas. Rinse thoroughly with clean water.
- Drying: Air dry all components completely on a clean drying rack or use a clean cloth. Ensure parts are fully dry before storage to prevent mold or bacterial growth.
Sterilization
Regular sterilization is recommended for all parts that come into contact with breast milk.
- Boiling: Place parts in a pot of boiling water for 5 minutes.
- Steam Sterilizer: Use a microwave or electric steam sterilizer according to its instructions.
- UV Sterilizer: Follow the manufacturer's guidelines for UV sterilization.
Inspection
Regularly inspect all accessories for signs of wear, tear, discoloration, or damage. Replace parts immediately if any damage is observed to ensure hygiene and optimal pump performance.
Troubleshooting
- Loss of Suction:
- Check the duckbill valve for any tears or debris, and ensure it is seated correctly. A damaged or improperly seated valve is a common cause of suction loss.
- Inspect the silicone diaphragm for any tears or holes, and ensure it forms a complete seal around the pump body.
- Verify that all tubing connections are secure and that the tubing itself is not kinked, pinched, or damaged.
- Pump Not Working Efficiently: If suction is weak or inconsistent, review the above points. Ensure all parts are clean and dry before assembly.
