1. Check that the duckbill valve is not sealed shut by pressing on the sides with your fingers. It’s completely normal for it to look ‘closed’ at rest, but if it is sealed shut even when you press on the sides as shown, contact us or try the spare that is in your Perifit Pump accessories!
2. Check that the duckbill valve is properly pushed into the connector
3. Make sure the flange is fully inserted into the connector
4. Check the positioning of the flange in the connector. To allow the milk to flow, the small hole should face towards the top of the connector (towards the diaphragm), and the large hole should face the bottom of the connector (towards where the milk bottle will screw on).
To make sure the flange is inserted correctly, please connect the 2 dots from the connector to the 2 dots from the flange.
5. Make sure you have a small seal joint/ring around your connector and that it is securely in place. If you lose it, there is a spare in the accessory bag.
6. Slide your connector assembly into the shell. Start by lining up the circular part at the top of the connector, with the ring inside the shell. Rotate the bottom of the connector slightly towards the front of the hub. You will hear a small click!
7. Check that the diaphragm is tightly pressed against the shell wall
8. Finally, screw the bottle onto the bottom of the connector. You are ready to pump!
