- Clean and Sanitize: Before first use and after each subsequent use, thoroughly clean and sanitize all parts that come into contact with breast milk (breast flange, milk bottle, backflow protector, duckbill valve). Refer to the "Cleaning & Maintenance" section for detailed instructions.
- Assemble Backflow Protector: Ensure the silicone diaphragm is securely seated within the plastic casing of the backflow protector.
- Attach Duckbill Valve: Firmly insert the duckbill valve into the bottom of the breast flange.
- Connect Bottle: Screw the milk bottle onto the bottom of the breast flange assembly.
- Attach Tubing: Connect one end of the tubing to the top of the backflow protector and the other end to the port on your Spectra breast pump.

3. Operation

- Position the breast flange correctly on your breast, ensuring your nipple is centered.
- Begin pumping at a comfortable suction level and adjust as needed.
- For double pumping, you will need two accessory kits.
4. Cleaning & Maintenance
Regular cleaning and proper maintenance are essential to ensure the longevity and hygienic operation of your Spectra accessory kit. Always clean parts immediately after each use.

Cleaning Instructions:
- Disassemble: Separate all parts of the accessory kit.
- Wash: Wash all parts that come into contact with breast milk (breast flange, milk bottle, backflow protector, duckbill valve) with warm soapy water. Use a dedicated brush for cleaning breast pump parts.
- Rinse: Rinse all parts thoroughly under clean 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.
- Tubing: Do not wash the tubing. If moisture or milk gets into the tubing, it should be replaced. The backflow protector prevents milk from entering the tubing and pump motor.
- Dishwasher: This product is not dishwasher safe. Hand wash only.
Replacement Schedule:
To maintain optimal performance and hygiene, certain parts of your accessory kit should be replaced periodically.

Image: A visual guide recommending replacement intervals: Spectra Duckbill Valves every 6 to 8 weeks, and Spectra Backflow Protectors every 3 to 4 months. It also advises purchasing two sets for double pumping.
- Duckbill Valves: Replace every 6 to 8 weeks, or sooner if you notice a decrease in suction or visible wear.
- Backflow Protectors: Replace every 3 to 4 months, or if you notice any damage or milk residue inside.
- Tubing: Replace if milk or moisture enters the tubing, or if it becomes discolored or damaged.
5. Troubleshooting
If you experience issues with your Spectra accessory kit, consider the following common troubleshooting steps:
- Low Suction:
- Check that all parts are assembled correctly and securely.
- Inspect the duckbill valve for tears or stretching; replace if necessary.
- Ensure the silicone diaphragm in the backflow protector is not torn or misaligned.
- Verify that the tubing is not kinked, damaged, or has moisture inside.
- Milk Leaking:
- Ensure the milk bottle is securely screwed onto the breast flange.
- Check the duckbill valve for proper seating and any damage.
- Discomfort During Pumping:
- Re-evaluate your flange size. An incorrect size can cause pain or inefficient milk expression.
- Adjust the suction level on your pump to a comfortable setting.
