4.4 Assembly Instructions
Follow these steps to correctly assemble your Lulia Hands-Free Breast Pump:
- Step 1: Connect the suction bowl to the tee fitting and install the duckbill valve at the bottom of the tee fitting. Ensure it is fully seated.
- Step 2: Attach the tee fitting to the flange. Make sure the tee fitting and flange are aligned as marked and pushed in firmly. The suction bowl and tee fitting must be aligned according to the marked lines.
- Step 3: Align the flange with the milk bowl at the position of the central milk inlet. The flange and milk bowl need to be aligned with the milk pouring spout for installation. Press firmly on the middle part of the flange to ensure the suction bowl fully enters within the marked line. The suction bowl must be fully pushed into the marked line to achieve a sealing effect.
- Step 4: Gently press the edge of the flange until it is tightly sealed.
- Step 5: Finally, align the main unit (motor) with the protruding port on the milk bowl for installation.
