Assembly
Before first use, disassemble, clean, and sterilize all parts that come into contact with breast milk. Ensure all parts are completely dry before assembly.
- Insert the duckbill valve firmly into the bottom of the pump body.
- Place the diaphragm onto the top of the pump body, ensuring it is seated securely.
- Attach the upper cover over the diaphragm, pressing down until it clicks into place.
- Screw the 24mm flange onto the pump body. If using the 21mm insert, place it inside the 24mm flange before attaching.
- Screw the milk bottle onto the bottom of the pump body, ensuring a tight seal.
- Connect one end of the air tube to the port on the upper cover of the pump body.
- Connect the other end of the air tube to the corresponding port on the motor unit. For double pumping, connect both tubes. For single pumping, connect one tube and ensure the other port on the motor is sealed (if applicable, or use a single-port setup).

Figure 6: The 4 distinct pumping modes.
- Suction Level Adjustment: Each mode has 9 adjustable suction levels. Use the "+" and "-" buttons to increase or decrease the suction intensity to your comfort level. Start with a lower level and gradually increase.
- Memory Function: The pump automatically remembers your last used mode and suction level for convenience.
- Auto Shut-off: For safety and convenience, the pump will automatically turn off after 30 minutes of continuous operation.
- Pumping Session:
- Ensure flanges are centered on your nipples for proper suction.
- Begin with a massage mode to stimulate let-down for 2-5 minutes.
- Once milk begins to flow, switch to an expression mode and adjust suction to a comfortable yet effective level.
- Pump until breasts feel empty or milk flow significantly slows.
