Pumping; Device Operation - Medela Harmony Mode D'emploi

3. Pumping

Caution
• Wash hands thoroughly with soap
and water before touching the
breast and pump parts.
• Always inspect breast shields,
valves and membranes prior to use
for cleanliness. If dirty, see
Section 1.2.
• Contact your healthcare
professional or breastfeeding
specialist if you can express only
minimal or no milk or if expression
is painful. See Section 7 for more
information.
• Do not try and express with
vacuum that is too high and
uncomfortable (painful). The pain,
along with potential breast and
nipple trauma may decrease milk
output.
• Step 2: Do not hold the pump
kit by the bottle. This can lead to
blockage of the milk ducts and
engorgement.
