Setup
Follow these steps to prepare your Medela Pump in Style for use:
- Wash Hands-free Collection Cups' parts: Before first use and after each use, wash all parts that come into contact with breast milk.
- Sanitize Hands-free Collection Cups' parts: Before first use and once per day, sanitize these parts. Refer to the cleaning section for detailed instructions.
- Assemble dry Hands-free Collection Cups' breast pump kit parts: Ensure all parts are completely dry before assembly to maintain hygiene and proper function.
- Insert tubing: Connect the tubing to the collection cups and the pump motor unit for either single or double pumping.
- Power your breast pump: Connect the power adapter to the pump and a wall outlet. Alternatively, you can use 8 AA batteries (not included) with the battery pack for portable use.
Operation
Once assembled and powered, your Medela Pump in Style is ready for operation. The pump utilizes 2-Phase Expression Technology to simulate a baby's natural nursing pattern, starting with a fast stimulation phase to initiate milk flow, followed by a slower expression phase for efficient milk removal.
Pumping Steps:
- Ensure breast shields are properly positioned on your breasts, creating a comfortable seal.
- Turn on the pump. It will automatically start in the stimulation phase.
- Once milk begins to flow, or after about two minutes, switch to the expression phase.
- Adjust the vacuum level to your comfort. The highest comfortable vacuum setting is recommended for optimal milk expression.
- Pump until milk flow slows or stops, typically 15-20 minutes per session.
- Turn off the pump and carefully remove the collection cups.

Cleaning and Maintenance
Proper cleaning and maintenance are crucial for the hygiene and longevity of your breast pump. All parts that come into contact with breast milk are dishwasher-safe.
Cleaning Instructions:
- After each use: Disassemble all parts that come into contact with breast milk (collection cups, breast shields, membranes). Rinse them with cold water immediately after use to remove milk residue. Then, wash them with warm, soapy water using a clean brush dedicated for breast pump parts. Rinse thoroughly with clean water.
- Daily sanitization: Sanitize the washed parts once per day. This can be done by boiling them in water for 5 minutes, using a steam sterilizer, or placing them in the top rack of a dishwasher.
- Drying: Allow all parts to air dry completely on a clean paper towel or drying rack. Do not use a cloth towel as it may transfer germs.
- Motor unit and tubing: The motor unit and tubing do not come into contact with breast milk and should not be washed or sterilized. Wipe the motor unit with a clean, damp cloth as needed. If milk gets into the tubing, replace it.

Troubleshooting
If you encounter issues with your Medela Pump in Style, refer to the following common troubleshooting tips:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not turning on or stops unexpectedly | Loose power connection, depleted batteries, faulty power adapter/battery pack. | Ensure power adapter is securely plugged into the pump and wall outlet. If using batteries, replace with fresh AA batteries and ensure proper insertion. Check for damage to the power cord or battery pack. |
| Low or no suction | Improper assembly of parts, damaged tubing, incorrect breast shield size, worn membrane. | Disassemble and reassemble all parts, ensuring a tight seal. Check tubing for kinks, cracks, or milk residue. Verify you are using the correct breast shield size for your nipple. Inspect the membrane for tears or damage and replace if necessary. |
| Collection cups unclip or leak | Parts not securely connected, damaged O-rings or seals. | Ensure all components of the collection cups are clicked into place firmly. Inspect O-rings and seals for wear or damage and replace if needed. |
| Insufficient milk expression | Incorrect flange size, low suction setting, infrequent pumping, stress. | Ensure your breast shield size is correct. Increase the vacuum level to the highest comfortable setting. Pump regularly and frequently. Try to relax during pumping sessions. If issues persist, consult a lactation professional. |
