Step 1: Before feeding, gently squeeze the anti-colic air vent to ensure it is open.
Step 2: Place the Collar over the Teat, ensuring that the Hegen logos on both items are aligned.
Step 3: Pull the Teat through the Collar until it is snugly fitted.
Step 4: Turn the Collar up and press on all four undersides of the Teat to ensure that it is fully secured.
Step 5: Place on the Transparent Cover for hygiene purposes.
Step 6: Press-To-Close to assemble the PPSU bottle to the Feeding Head (the assembled collar, teat and transparent cover).
For a leak-resistance experience, tighten the collar by turning it clockwise to secure the bottle.
Now your bottle is ready for use!
