Warnings to avoid contamination and to ensure hygiene:

 

-

For hygienic reasons, the breast pump is only intended for repeated use by a 

single user.

 

-

Clean and disinfect all parts before first use and after each use.

 

-

Do not use antibacterial or abrasive cleaning agents to clean the breast 

pump parts as this may cause damage.

 

-

Wash your hands thoroughly with soap and water before you touch breast 

pump parts and breasts to prevent contamination. Avoid touching the inside 

of containers or lids.

Warnings to avoid breast and nipple problems including pain:

 

-

Always release the handle before you remove the pump body from your 

breast in order to release the vacuum.

 

-

If the vacuum is uncomfortable or causes pain, stop pumping and remove 

the breast pump from your breast.

 

-

Do not continue pumping for more than five minutes at a time if you do not 

succeed in expressing any milk. Try to express at another time during the day. 

 

-

If the process becomes very uncomfortable or painful, stop using the pump 

and consult your healthcare professional.

 

-

Only use accessories and parts recommended by Philips Avent.

 

-

No modification of the breast pump is allowed.

Warning: 

If you are infected with Human Immunodeficiency Virus (HIV) or 

Hepatitis B or C, using the breast pump will not reduce or remove the risk of 
transmitting the virus to your baby through breast milk.

Caution

Caution to prevent damage to and malfunctioning of the breast pump:

 

-

Keep the parts away from heated surfaces to avoid deformation of these parts.

Preparing for use

Disassemble, clean and disinfect all parts before you use the breast pump 
for the first time and after every use.

 Caution: Be careful when you remove and clean the white valve. Do not 

insert objects into the white valve, as this may cause damage.

Cleaning and disinfecting

Step 1: Disassembling

Disassemble the breast pump and bottle completely. Also remove the white 
valve from the pump body and the stem from the silicone diaphragm.

Step 2: Cleaning

The parts can be cleaned manually or in the dishwasher. 

Step 2A: Manual cleaning

Rinse all parts under a running tap with lukewarm water.

Clean all parts with a cleaning brush in warm water with some mild 

dishwashing liquid.

Thoroughly rinse all parts under a running tap with cold clear water.

Leave all parts to air-dry on a clean tea towel or drying rack.

Step 2B: Cleaning in the dishwasher

 Note: Food colorings may discolor parts.

Place all parts on the top rack of the dishwasher.

Put dishwashing liquid or a tablet in the machine and run a standard program.

Leave all parts to air-dry on a clean tea towel or drying rack.

Step 3: Disinfecting 

 Caution: During disinfection with boiling water, prevent the bottle or 

other parts from touching the side of the pot. This can cause irreversible 

product deformation or damage that Philips cannot be held liable for.

Fill a household pot with enough water to cover all parts and place all parts 

in the pot. Let the water boil for 5 minutes. Make sure the parts do not touch 

the side of the pot.

Allow the water to cool down.

Gently remove the parts from the water. Place the parts on a clean surface, 

tea towel or drying rack to air-dry.

Assembling the breast pump

Make sure you have cleaned and disinfected the parts of the breast pump 
that come into contact with milk. 

 Warning: Be careful, when you have disinfected the breast pump 

parts by boiling them, they can be very hot. To prevent burns, only start 

assembling the breast pump when disinfected parts have cooled down.

Check the breast pump kit parts for wear or damage before use and replace 
them if necessary.

 Note: Correct placement of the cushion and the silicone diaphragm is 

essential for the breast pump to form a proper vacuum.

Insert the white valve into the pump body from underneath. Push the valve 

in as far as possible (Fig. 2).

Screw the pump body clockwise onto the bottle (Fig. 3) or storage cup (Fig. 4) 

until it is securely fixed. 

 Note: If you use a storage cup, you have to screw the adapter for cup onto 

the storage cup first (Fig. 4).

Push the stem into the silicone diaphragm fully to the end (Fig. 5).

Insert the silicone diaphragm into the pump body from above. Make sure it 

fits securely around the rim by pressing down with your fingers to ensure a 

perfect seal (Fig. 6).

Attach the handle onto the diaphragm with stem by hooking the hole in the 

handle over the end of the stem. Push down the handle onto the pump body 

until it clicks into place (Fig. 7).

Place the cushion into the pump body (Fig. 8) and make sure that the rim 

covers the pump body. Push the inner part of the cushion into the funnel. 

Make sure that you push the cushion inwards completely, up to the line 

indicated with an arrow on the pump body (Fig. 9).

 Note: Place the cushion cover (SCF430/10, SCF430/13, SCF430/15) over the 

cushion to keep the breast pump clean while you prepare for expressing.

Using the breast pump

 Warning: Always use the breast pump with the cushion.

 Note: Contact your healthcare professional in case of questions or if you 

experience side effects.

Operating the breast pump

Wash your hands thoroughly with soap and water and make sure that your 

breast is clean.

Press the assembled pump body against your breast. Make sure that your 

nipple is centered, so that the cushion creates an airtight seal.
