3.5 EMC

The electric breast pump complies with the limits for group 1, class B of a medical electrical device (according to CISPR 11).

Electromagnetic compatibility (EMC) refers to the ability of a device to function properly in its electromagnetic environment without inducing inadmissible electromagnetic interferences. Such interferences can be transmitted among others by connecting cables or air.

Inadmissible interference from the environment can lead to incorrect behaviour of the medical device. Likewise, in certain cases the electric breast pump can cause such interferences with other devices. To resolve the problems, one or more of the following measures should be taken:

• Change the orientation or distance of the device to the source of the interference.
• Use the electric breast pump in a different location.
• Please contact our customer service for further information.

The electric breast pump must not be used directly next to or stacked with other appliances. If such operation is required, the electric breast pump must be observed in order to check its intended operation in this arrangement.

Further precautions with regard to electrical disturbances to maintain basic safety during expected service life are not provided.

Note:

The electric breast pump has no essential features according to EN 60601-1. The system may be interfered with by other devices, even if these devices comply with the emitting requirements specified in CISPR 11 (Comité international spécial des perturbations radioélectriques - International Committee on Radio Interference).

Warning!

Portable HF communication devices (radio devices) (including their accessories, such as antenna cables and external antennas)

should not be used at a distance of less than 30 cm (or 12 inches) to the parts and pipes of the electrical breast pump. Failure to do so may result in a reduction in the performance of the equipment.

Warning!

Modifications or extensions to the device or the use of non-recommended accessories (E.g. mains adapter or USB cable) can result in increased electromagnetic interference or a reduced electromagnetic immunity of the device and lead to a faulty operation.

9 Breast shield

10 Silicone cushion

11 Lip valve

12 Breast milk container

15 Feeding teat

16 Screw ring

17 Protective cap

18 Sealing disc

Warning! Milk residues may damage the product and result in microbial growth.

Caution! The parts should not be cleaned in a dishwasher – dishwasher detergents can cause product damage.

Note: When rinsing with dishes (for example), certain foodstuffs may discolour the material (e.g. carrot juice) or affect its odour (e.g. fennel tea). This has no effect on the fitness for use or safety of the bottle.

1. Next, sterilise all parts (see "5.2 Sterilising" on page 28).

2. Wipe the pump unit 3 with a damp cloth.

5.2 Sterilising

Before sterilising, clean as described in the section entitled "5.1 Cleaning").

Warning! Risk of scalding during sterilisation.

Caution!

- Dismantle each part into its individual components for boiling or steam-sterilizing (temperature above 80 °C) and leave open, otherwise deformation can result.

- The pump unit 3 and the mains adapter 13 must never be sterilised in this way, as this can damage the electrical contacts and cause deformation.

• Incorrect treatment can damage the parts.
• Before using again, allow the sterilised parts to cool and dry completely before reassembling.

• Only use water and steam for sterilisation:

• Use a NUK Steam Steriliser, following the operating instructions of the device.

Alternatively,

1. sterilise the parts in boiling water for 5 minutes.

Ensure there is sufficient water in the pan to avoid damage.

Alternatively,

1. use a NUK Micro Express Plus Microwave Steam Steriliser for sterilisation in your microwave oven.

- Only use the NUK Micro Express Plus Microwave Steam Steriliser for microwave sterilisation. Follow the operating instructions of the device.

5.3 Special cleaning of tube and filter

1. If milk enters the tube 4, switch the device off immediately.
2. Dismantle the device as shown in figure B, proceeding in reverse from 7 to 1.
3. Remove the filter 6 (see figure C).
4. Clean the following parts with lukewarm water and a little washing-up liquid and/or NUK Rinsing Agent:

-rinse filter 6;
- flush tube 4 with tube connector plug 7.

1. Reassemble according to figure C or B in reverse order and then use the blow-dry function (see "5.4 Tube blow-dry function" on page 29) of the device to dry the tube 4 and the tube connector plug 7.

Note: Since the filter 6 would be a virtually impermeable barrier while wet or damp, it would inhibit the blow-dry function and the pump suction. Insert the dry replacement filter instead. Leave the freshly cleaned and rinsed damp filter to air-dry for at least 4 hours.

5.4 Tube blow-dry function

1. Assemble the device as shown in figure B. Do not insert a filter that is still damp, but use a dry replacement filter instead.
2. To start the blow-dry function press the master power switch 126 and then simultaneously touch the buttons 22 and 11 25.

The blow-dry function runs for 5 minutes.

1. Check that the tube is completely dry (no droplets visible inside), before starting the next pumping session.

If the tube is not yet completely dry, start the blow-dry function again.

You can pause the blow-dry function by touching the Pause button 25 and continue it later by touching the Pause button 25 again.

1. To stop the blow-dry function, switch the pump unit off by pressing the master power switch 26.

6 Assembling the pump

1. Assemble the device as shown in figure B.

Note: Make sure the silicone cushion 10 fits snugly in the breast shield 9 and the lip valve 11 is properly mounted, as the pump can otherwise draw in air, which will prevent it from working properly.

Starting the pumping session

1. Position the breast shield 9 with the fitted silicone cushion 10 on your breast so that your nipple is in the centre of the shield. Gently press the breast shield in place in order to ensure a good seal for expressing your milk. In doing so, take care to keep

the breast milk container 12 attached to the breast shield in an upright position.

Caution! To ensure the required results, never allow the milk level to rise beyond the lower rim of the lip valve 11.

1. To start pumping, touch either of the buttons ⏻ 22, — 23, or + 24.

Pumping will start with the fastest suction rhythm and the lowest suction strength (default setting).

Setting the suction strength

1. Use the buttons - 23 and + 24 to adjust the suction strength to one of 4 levels.

Touch-and-hold will cause the suction strength to adjust step by step up to the maximum or minimum level respectively.

The selected suction strength is displayed with 31 (First Choice ^+ ) or 38 (Nature Sense).

You can adjust the suction strength any time during the pumping session.

Setting the suction rhythm

1. Touch the 📄 22 button once to adjust the suction rhythm to the next level.

Touch-and-hold will cause the suction rhythm to adjust step by step until you release the button.

The selected suction rhythm is displayed with 27 (First Choice ^+ ) or 32 (Nature Sense).

You can adjust the suction rhythm any time during the pumping session.

Pause mode

1. Touch the Pause button 25 to place the pump unit into pause mode. To continue pumping, touch the Pause button 25 again.

Memory function

The memory function can be used to save the sequence of a pumping session from the moment it is started.

1. To save a pumping session, you must first change to pause mode by touching the Pause button 25.

2. Then touch the Memory button 21 for at least 2 seconds.

While the session is being saved, the symbol 28 (First Choice ^+ ) or 33 (Nature Sense) will flash.

Once the session has been saved, the pump will return to start-up mode.

1. To start the saved session, touch the Memory button 21 while the pump unit is in start-up mode after being switched on. The symbol 28 (First Choice ^+ ) or 33 (Nature Sense) is lit.

5. If you used the mains adapter 13, unplug it in order to ensure that the device is completely disconnected from mains power.
6. Unscrew the breast milk container 12 from the breast shield 9.

Make sure you hold the breast milk container upright while doing so.

1. Clean the necessary components immediately after completing your pumping session (see "5 Cleaning and Sterilising" on page 28).

8.2 Automatic switch-off

If no buttons are touched during operation (during an active pumping session), the pump unit will automatically switch to start-up mode after 30 minutes.

This does not apply when the Memory function is being used. In other words, once started, a saved pumping session will always run through until the end before the device switches to start-up mode.

If no buttons are touched when the pump unit is in start-up mode or pause mode, it will automatically switch off after 15 minutes.

8.3 Mobile operation

You can also use the pump while moving about your room, using the shoulder strap to carry it.

The shoulder strap is securely fixed to the pump unit.

1. Should the shoulder strap need cleaning, detach it from the lug 1, wash it in water with a little soap or gentle detergent, and air dry it

2. before reattaching it to the lug 1 on the pump unit.

Note: The shoulder strap 20 must not be sterilised.

8.4 Feeding expressed milk

Screw the feeding teat 15 onto the breast milk container 12 using the screw ring 16.

9 Tips for Successful Expressing

Correct expressing takes practice. You will first need to get used to your new pump.

9.1 Frequency

How often you need to express depends on the reason for expressing. If you will be apart from your child and/or want to sustain milk production, the natural breastfeeding rhythm should be maintained. You should therefore express 6 to 8 times daily, including once during the night. In all other cases you should express entirely according to your personal wishes and requirements.

9.2 Method

Milk should be expressed from each breast in turn. The different settings you can choose for your pumping session allow you to emulate the natural suckling action of your baby as closely as possible.

• In the "stimulation phase", the rhythm is rapid and urgent to stimulate the milk flow reflex. This emulates the suckling action of most babies, which will initially suck rapidly and avidly at the start of feeding.
• In the "milk flow phase", suction is slow and strong to ensure maximum milk flow.

Again, this corresponds to most babies' natural behaviour. As soon as a baby's initial appetite is satisfied, it will change to a calm, slow and intensive sucking action while drinking its fill.

If the milk flow drops:

• Change breast
• Alternatively, you can repeat the "stimulation phase" in order to stimulate your milk flow reflex anew.

The amount of time needed to express milk will vary considerably from one person to another.

9.3 Quantity of milk

Don't be surprised if it takes a little while for the milk to start to flow properly at first. This is not unusual. In fact it is quite normal because

milk production adapts itself to daily requirements.

This means that the quantity of milk produced may vary considerably.

• Ensure you drink plenty of liquid yourself.
• Do not set suction strength too high. A higher suction strength does not increase the quantity of milk produced.

9.4 Let-down reflex

During natural breastfeeding, placing the baby on the breast stimulates the let-down reflex and milk begins to flow. You can also stimulate the let-down reflex as follows:

• Find yourself a quiet place to sit, where you can relax fully when using the breast pump.
• Adopt a comfortable and relaxed sitting position.
• Place a warm compress on your breast for a few minutes, to relax the tissue, and massage your breast.
• The let-down reflex triggers milk flow in both breasts simultaneously. You can use the NUK Breast Shell Set to collect breast milk leaking from the breast you are not currently expressing.

10 Hygiene tips

Hygiene is particularly important when using the breast pump. This applies to all the individual pump components as well as to your own personal hygiene. We recommend regularly washing your nipples in clean water. Where possible, avoid using soap on your nipples, as this can cause irritation.

11 Storing Milk

11.1 With Breast Milk Container

Breast milk may be chilled, frozen and defrosted in the breast milk container 12. The breast milk container 12 may also be used for warming and feeding. It is important that you follow the instructions about handling breast milk which is provided in “11.2 Important notes for handling breast milk” on page 34.

Warning! To ensure adequate hygiene at all times:

If your collected breast milk is not for immediate use, firmly seal the filled breast milk container 12 with the sealing disc 18 and screw ring 16 and store it in your refrigerator or freeze it.

Using a suitable pen or label, write the date and the time when the breast milk was expressed. Be sure to note the retention periods in “11.2 Important notes for handling breast milk” on page 34.

Caution! To avoid damage:

- When freezing breast milk, do not fill the breast milk container 12 with more than 150 ml (5 fl oz), as breast milk expands as it freezes and the container could burst.

For a spacesaving solution you can use NUK Breast Milk Bags for freezing and storage of breast milk.

11.2 Important notes for handling breast milk

Breast milk Storage location Storage periods
Freshly expressed	At room temperature Max. 6-8 hours
	Refrigerator (not in door) 72 hours at 4 °C
	Refrigerator freezer compartment 2 weeks
	Upright/chest freezer 6 months at -18 °C
Defrosted, unopened	Refrigerator (not in door) 24 hours at 4 °C
Defrosted, opened	Refrigerator (not in door) 12 hours at 4 °C
Defrosting milk	Gradually in refrigerator	Approx. 24 hours at 4 °C
	At room temperature followed by immediate feeding
	If time is short, defrost container with breast milk in lukewarm water (max. 37°C), then feed immediately.

Warning! To ensure adequate hygiene at all times:

If transporting chilled breast milk make sure that it stays chilled at all times, otherwise the milk could go off and be harmful to your baby. Use a cooler bag with ice packs, for example.

Defrosted, warmed or unused milk must be disposed of and not refrozen.

Warning! Risk of scalding and risk of destroying valuable nutrients:

Do not use a microwave to defrost breast milk, as this can destroy valuable nutrients and damage the container material (risk of explosion). Uneven heating may result in scalding!

If milk is heated excessively, you risk destroying the vitamins and other valuable nutrients it contains. There is also a risk of scalding for your baby.

Always check the temperature of your warmed up breast milk before feeding it to your baby.

1. To achieve the correct drinking temperature of approx. 37 °C, put the container of defrosted breast milk in the baby food warmer.

Caution! The container must be open to prevent pressure build-up as the milk warms up.

1. Shake the milk gently before feeding so that milk and milk fat are properly mixed again.

2. If you express breast milk more than once within a period of 24 hours, the freshly expressed milk may be added to the previously cooled breast milk.

However freshly expressed milk must be cooled down before being added to milk that is already cool. The temperatures must be the same (cold on cold).

Notes:

• Consult your health visitor, midwife, doctor or pharmacist for detailed information about long-term storage.
• You can find more information about breastfeeding on our NUK website (www.nuk.com).

12 Troubleshooting

Problem Reason Remedy
Pump does not work	No power supply Battery operation	on: Check that the battery is adequately charged (see "7.3 Battery operation (Nature Sense model only)" on page 30).
		For mains operation: check that the mains plug and mains adapter are correctly inserted
		External power bank: Check that the power bank is adequately charged.
	Lip valve missing, incorrectly positioned or damaged	Check that the lip valve is correctly positionedIf it is damaged, use the replacement lip valve supplied
	Breast milk container is full and lip valve is already contacting the expressed milk	Replace breast milk container
	No suction or suction level too low	Check that the lip valve is correctly fitted.
		Make sure that the breast shield forms a complete seal around your breast.
	Filter is wet Remove filter and a	low more time to dryor use dry replacement filter (see "5.3 Special cleaning of tube and filter" on page 29).
Pump suction is weak	Low battery power Check whether battery power is sufficient (see "7.3 Battery operation (Nature Sense model only)" on page 30).
	Suction strength is set too low Increase the suction strength until you achieve the best results (see "Setting the suction strength" on page 31).
	Silicone cushion incorrectly positioned and not properly flush with the breast shield	Ensure that the silicone cushion is completely flush with the breast shield
	No vacuum can be built up Ensure that the breast shield is completely flush with the breast
	Filter blocked Clean or replace filter (see "5.3 Special cleaning of tube and filter" on page 29).
	Filter is wet Remove filter and a	low more time to dryor use dry replacement filter (see "5.3 Special cleaning of tube and filter" on page 29).
Pump suction too strong	Suction strength is set too high Reduce suction strength (see "Setting the suction strength" on page 31).
Pump making strange noises	Lip valve unable to cope with milk flow volume	Reduce suction strength (see "Setting the suction strength" on page 31). If you have a high milk flow volume, a low suction strength will be perfectly adequate to achieve good results.
		Check whether the breast milk level has already reached the lip valve. If so, replace the breast milk container with an empty one.
	Milk has entered the tube Imme	diately switch off the pump unit and clean the tube and the filter (see "5.3 Special cleaning of tube and filter" on page 29).
Nature Sense:The display shows symbol!First Choice+:Symbol X is lit in the display	Inadequate power supply: Not enough current supplied through mains adapter or power bank	Mains power operation:Check that the mains adapter is properly plugged in to the power supply socket and the USB connector is firmly pushed into the port on the pump unit.Check that you are using the correct mains adapter included in the delivery package.
		External power bank: Check that the USB cable is connected to the 2A output of the power bank and that the power bank is adequately charged.
