Follow these steps to assemble your Medela Pump in Style Pro breast pump before first use:
- Clean and Sanitize: Before initial use, wash and sanitize all parts that come into contact with breast milk according to the "Cleaning and Care" section.
- Assemble Breast Shields and Connectors: Attach the appropriate size PersonalFit Plus Breast Shield (21mm or 24mm) to a connector. Ensure the membrane is securely in place on the connector.

4. Operating Instructions
The Medela Pump in Style Pro offers two distinct pumping modes and 16 vacuum levels for personalized comfort and efficiency.
4.1 Pumping Modes
- Stimulation Mode: This mode mimics a baby's initial fast, light sucking to stimulate milk let-down. The pump will automatically start in this mode.
- Expression Mode: Once milk begins to flow, switch to expression mode, which uses slower, deeper suction to efficiently remove milk.
4.2 Adjusting Vacuum Levels
The pump features 16 adjustable vacuum levels. Begin pumping at a comfortable vacuum level and gradually increase it until you find the maximum comfortable suction that allows for efficient milk flow. The pump unit has clear level indicators to help you track your settings.

4.3 Pumping Session
- Ensure all parts are clean, assembled, and connected correctly.
- Center your nipple in the breast shield tunnel.
- Turn on the pump. It will start in stimulation mode.
- Once milk begins to flow, press the mode button to switch to expression mode.
- Adjust the vacuum level to your comfort.
- Pump for approximately 15-20 minutes, or until milk flow significantly slows.

5. Cleaning and Care
Proper cleaning and care of your breast pump parts are crucial for hygiene and optimal performance.
5.1 Parts to Clean After Each Use
All parts that come into contact with breast milk (breast shields, connectors, membranes, bottles, lids) must be cleaned after each use.
- Disassemble: Separate all parts that came into contact with milk.
- Rinse: Rinse parts under cool running water to remove milk residue.
- Wash: Wash parts in warm, soapy water using a mild dish soap. Use a clean brush dedicated for feeding equipment.
- Rinse Thoroughly: Rinse all parts thoroughly under running water.
- Air Dry: Place parts on a clean paper towel or drying rack and allow them to air dry completely. Do not use a cloth towel to dry, as this can transfer germs.
5.2 Sanitizing
Sanitize parts at least once a day, especially for infants younger than 3 months, those with weakened immune systems, or those born prematurely.
- Boiling: Place disassembled, cleaned parts in a pot of boiling water for 5 minutes.
- Steam Sterilization: Use a microwave steam sterilizer bag or a dedicated electric steam sterilizer according to manufacturer instructions.
5.3 Pump Unit and Tubing
The pump unit and tubing do not come into contact with breast milk and therefore do not require washing or sanitizing. If the tubing becomes visibly dirty or moldy, it should be replaced. Wipe the pump unit with a clean, damp cloth as needed.
