Setup Instructions
Initial Preparation
- Wash Hands: Before handling any breast pump components, thoroughly wash your hands with soap and water.
- Clean Components: Although the pump comes fully assembled, it is recommended to disassemble and clean all parts that come into contact with breast milk before first use. Refer to the "Maintenance and Cleaning" section for detailed instructions.
- Charge Battery: Ensure the breast pump is fully charged before initial use. Connect the provided USB cable to the charging port located on the side of the pump and plug it into a suitable USB power source.
- Select Flange Size: The pump comes with 28mm flanges pre-installed, along with 21mm and 24mm inserts.

Operating the Breast Pump
Powering On/Off
- To turn on the pump, press and hold the power button (usually indicated by a circular icon) on the top of the unit until the indicator light illuminates.
- To turn off the pump, press and hold the power button again until the indicator light turns off.
Mode Selection
The NCVI breast pump offers multiple modes to suit your needs. Press the 'M' button to cycle through the available modes:
- Massage Mode: Designed to stimulate milk let-down with gentle, rapid suction patterns.
- Normal Mode: Provides a steady, consistent suction for efficient milk expression.
- Pacifier Option (Simulation Mode): Mimics a baby's natural suckling rhythm and pattern.
- Combination Mode: Alternates between light and stronger suction patterns.
Intensity Adjustment
Each mode has 9 adjustable intensity levels. Use the '+' and '-' buttons to increase or decrease the suction strength to your comfort level.
Milk Collection
The transparent milk collection cup has measurement markings on the side. When the milk reaches the maximum fill line, the pump should be paused, and the milk transferred to a storage container to prevent overflow.
Care and Maintenance
Proper cleaning and maintenance are crucial for the longevity and hygiene of your breast pump. All parts that come into contact with breast milk are BPA-free and easy to clean.
Disassembly for Cleaning
- Separate the pump motor from the milk collection cup by pressing the release button on the front of the pump.
- Twist off the lid of the milk collection cup.
- Carefully pull out the diaphragm and flange insert from the main flange unit.
- Disassemble any other removable parts as indicated in the detailed manual.
Cleaning Guidelines
- Wash all disassembled parts (excluding the pump motor and USB cable) with warm, soapy water immediately after each use.
- Rinse thoroughly with clean water.
- Air dry on a clean drying rack or use a clean cloth. Ensure all parts are completely dry before reassembly.
- The pump motor and USB cable should not be submerged in water. Wipe them clean with a damp cloth if necessary.
Reassembly
Once all parts are dry, reassemble the pump by reversing the disassembly steps. Ensure all components are securely fitted to maintain proper suction.
