- Step 1: Attach Diaphragm to Flange. Press the silicone diaphragm firmly onto the top of the flange, ensuring the edges seal completely without any gaps.
- Step 2: Insert Valve. Push the valve into the designated opening at the bottom of the flange. Ensure it is securely seated.
- Step 3: Connect Flange to Milk Collector. Align the assembled flange with the milk collector and press them together, ensuring a tight seal around the connecting edges.
- Step 4: Attach Pump Motor. Place the pump motor onto the top of the assembled milk collector and flange unit. Press down gently until it clicks into place, forming a secure connection.
Choosing the Correct Flange Size:
Selecting the correct flange size is crucial for comfort and pumping efficiency. Use the included nipple measure tool to determine your size.
