Medela Lactina and Classic Breast Pump General Instructions User Manual

When freezing, do not fill containers more than 3/4 full 

to allow space for expansion. Label containers with the date

of pumping.

• To inhibit the growth of bacteria, breastmilk which is not

used immediately should be refrigerated. Milk can be

refrigerated 5-7 days or, if longer storage is needed, milk

can be frozen.

• In the freezer compartment inside a refrigerator, breast-

milk can be stored for approximately six months.

• In a separate -20° C freezer, breastmilk can be stored for

approximately 12 months.

• Thaw frozen breastmilk by holding the container under

warm water. Thawed milk is safe to use for 24 hours. Gently

shake the container to blend any fat that has separated.

• Do not thaw frozen breastmilk in a microwave or in a

pan of boiling water.

• If adding expressed breastmilk to container of already

frozen breastmilk, make sure to add a smaller amount

than the amount that is already frozen.

Inspect tubing after each pumping session for condensation

and or milk.

To eliminate condensation after you have completed pump-

ing, continue running the pump with the tubing attached for

another 1-2 minutes or until dry.

1.  Turn off the pump and unplug from power source.
2. Remove and disassemble the tubing, pump connector, 

piston, cylinder and barrier filter (parts vary by pump

used). Except for barrier filter, wash in soapy water then

rinse in cold clear water. The barrier filter may be cleaned

by rinsing in warm water without soap.

3. Shake water droplets out of tubing and hang to air-dry.

For faster drying, attach tubing to pump and run pump 

1-2 minutes or until dry, or pour a small amount of 

isopropyl alcohol through the tubing to dry.

The inside of the cylinder has to be smooth at all times. If a

buildup of mineral deposits or a white film is evident inside

the cylinder, such buildups must be removed to prevent wear

on the rubber

seal. For this pur-

pose, clean cylin-

der again with

lukewarm soapy

water or a vine-

gar and water

solution. Rotate the piston in the cylinder every so often to

ensure that the rubber seal is worn evenly. Washing the rub-

ber seal and the vacuum regulator ring with warm soapy

water will also prolong the life of these parts. Only

sterilize/sanitize these parts when milk is evident on them. Be

sure the rubber seal is completely dry before using.
