Flange Size Chart

4.1.1 Stimulate The Nipple

1. Stimulate your nipple to get a full size (do not skip this step!).
2. Place the nipple into the smallest hole you can comfortably fit into without forcing it.
3. Select the hole that can comfortably fit the very base of your nipple.
4. Get your measurement based on the size chart.

4.1.2 Test The Flange Fit

1. To find the suitable flange size, first, you need to make sure you place the flange in the right place on your breast.
2. Please press the flange on your breast until there is no gap. Make sure your nipple is right in the middle of the flange.

Too small: During pumping, if your nipple continues to rub against the inner wall of the flange, then this flange is too small for you.
Good Fit: During pumping, if your nipple moves smoothly without rubbing or touching the inner wall of the flange, and almost no areola is sucked inside, then this flange is right for you.
Too large: During pumping, if a large area of areola is sucked inside, then this flange is too big for you.
4.2 Get The Right Bra

PUMPING

5.1 Assembly

1. Wash your hands thoroughly with soap and water.
2. Install the valve to the milk collector, paying attention to the direction of installation.
3. put the silicone diaphragm into the milk collector, and press it with your hands ‘to make the edges fasten tightly to ensure a perfect seal.
4. Connect the flange with the main body. Make sure that the flange fits securely around the rim by pressing it down with your thumbs.
5. Install the main body of the breast pump on the milk collector, align the notch under the main body with the silicone diaphragm, and assemble it downward tofit the milk collector to ensure a complete seal.

5.2 Alignment

1. In the process of pumping, please make sure the pump is pressed tightly.
2. To align, hold the flange against to your breast so you can see whether your nipple is centered in the flange tunnel or not. You may need to bend forward.
3. After you’ve aligned, look through the flange to confirm your nipple is centered before connecting the pump. The tip of your nipple should not touch the top, sides or bottom of the flange tunnel. If it does, try again.

IMPORTANT:

• Correct nipple alignment is key to comfort expression and performance.

• Nipple must be positioned correctly in Flange Tunnel before pumping to avoid discomfort.

• See Section 4.1. GETTING STARTED-Select Flange Size.
  5.3 Secure Pump In Bra

  2. Secure pump in place by bra, taking care to keep pump pressed firmly against breast. If necessary, tighten bra to keep pump securely in place and start pumping.

5.4 Turn On Pump

Long press the On / Off / Pause button to turn on or turn off the pump.
Tip: Momwills pump gets warm during running. Don’t worry! This is normal.
5.5 Vacuum Pressure Settings
Momuwills pump has 9 vacuum pressure settings for each mode, giving you control over what feels comfortable and works most efficiently in both stimula- tion and expression modes.
Once you can feel the vacuum pressure on your nipple, use the Increase/De- crease button to adjust vacuum pressure to find your preferred setting in both modes. The remote controller LED display will be off after no operation for 20 seconds, press any button can activate the LED display.
Tip: A higher vacuum pressure does not always mean a higher volume of milk. Putting your nipple under excessive stress can reduce milk production.
Always ensure you are pumping at a comfortable level. If you don’t feel suction, please check the pump is assembled correctly (see section 5 PUMPING-5.1 Assembly).
