Each side has its own motor and controls. Check both batteries and start with clean, fully dry collection pieces.

1. Attach the valve horizontally. Fit the diaphragm with its notch facing the flange/breast side, then press its rim firmly into place.
2. Align the pour spouts, press the flange firmly around its entire edge and close the spout cover.
3. Align the underside of the motor hub with the diaphragm and press it into an airtight connection. Keep the pump upright and steady in your bra.

If suction seems weak or absent, check the charge, component orientation and complete flange seal before changing settings. Stop if pumping hurts; seek qualified help for pain or feeding concerns.

Have a milk-storage container ready before removing the pumps:

1. Turn the pump off and release the breast seal gently with a finger.
2. Keep it upright while taking it out of your bra, then remove the motor hub before tilting it to pour.
3. Pour through the slot at the top of the collection cup, keeping the flange tunnel facing up.

Label and store the milk using the fresh and thawed milk limits. In-bra collection still requires somewhere to transfer milk and handle used equipment.

Wash the collection pieces

Keep the motor hub out of water. Rinse washable pieces in cold water after use, then hand-wash in warm soapy water in a dedicated basin. A brush may be used on hard plastic, but not on silicone pieces.

Dry before packing

Rinse with clean water and let the pieces air-dry fully without rubbing them dry. Do not assemble or seal damp pieces in a bag. Flow's care instructions prohibit microwave disinfection.

Charge between uses

The pumps cannot operate while charging. Use the supplied cables with a 5V 2A supply; do not use fast-charge cables or adapters. Check each hub's charge before relying on it for another session.

For repeated sessions away from home, allow drying time or bring a complete clean, dry collection set for each side you will use. Extra inserts alone do not make a complete set. See the cleaning routine and complete-kit inventory.
