4. ALIGNING THE PUMP
Bring Pump to your breast, centering your nipple in the Flange tunnel.
IMPORTANT: Correct nipple alignment is key to
comfort, output and performance
• Nipple must be positioned correctly in Flange
tunnel before pumping to avoid discomfort
• If you still experience discomfort with proper
placement, you may need a dierent Flange
size. Use the Nipple Sizing Tool to help select
the appropriate Flange size.
• Use a full-coverage nursing bra with nursing
ap that supports the Pump rmly at top and
bottom. For best support, you do not need to
go up a cup size.
