4. Setup
4.1. Cleaning Before First Use
Before using your breast pump for the first time, and after each subsequent use, all parts that come into contact with breast milk must be cleaned and sterilized. The breast flanges are dishwasher-safe.
- Disassemble all parts that come into contact with breast milk (e.g., breast flanges, valves, bottles).
- Wash these parts in warm, soapy water using a mild dish soap. Use a dedicated brush for breast pump parts.
- Rinse thoroughly with clean water.
- Sterilize by boiling in water for 5 minutes, using a steam sterilizer, or a dishwasher (if applicable for specific parts).
- Allow parts to air dry completely on a clean surface or use a clean cloth.
- The main pump unit and tubing should not be washed or sterilized. Wipe the main unit with a clean, damp cloth.
4.2. Assembling the Pump
Follow these steps to assemble the breast pump for use:
- Ensure all parts are clean and dry.
- Attach the valve to the bottom of the breast flange.
- Screw the milk collection bottle onto the breast flange.
- Connect the tubing to the breast flange connector and the main pump unit. Ensure a secure fit.
- Repeat for the second breast flange assembly if using in double pumping mode.
4.3. Powering the Pump
The pump can be powered via the included power adapter.
- Connect the power adapter to the main pump unit and plug it into a wall outlet.
- The pump also has an internal rechargeable battery for portable use. Ensure the battery is charged before use if not connected to a power outlet. The battery indicator on the display will show the charge level.
5. Operating Instructions
5.1. Getting Started
- Find a comfortable position.
- Center the breast flange over your nipple, ensuring a good seal around your breast.

5.2. Selecting a Mode
The pump defaults to Stimulation Mode upon startup. You can switch between modes using the dedicated mode button (often indicated by a droplet icon or "Expression / Stimulation" label).

- Expression Mode: Once milk flow begins, switch to Expression Mode. Adjust vacuum levels (1-10) and speed levels (1-6) for efficient milk expression.
5.3. Adjusting Suction and Speed
Use the '+' and '-' buttons for both "Speed Adjustment" and "Suction Adjustment" to customize your pumping experience. Start with lower settings and gradually increase to a comfortable, effective level. Pumping should never be painful.
5.4. Using UIS (Unique Independent Settings)
The UIS feature allows you to set different vacuum and rhythm controls for each breast when double pumping. Consult the on-screen indicators and specific buttons (if available) to adjust each side independently.
