3.4 Notes for the Breast Milk

Container and Teat For your child’s safety and health: WARNING!

• Always use this product with adult supervision.

• Never use feeding teats as a soother.

• Continuous and prolonged sucking of fluids will cause tooth decay. This applies in particular to sweetened drinks and fruit/vegetable juices.

• Always check food temperature before feeding.26

• Always check the teat for signs of excessive wear by pulling the teat in all directions before each use especially when the child has teeth. Replace when sticky from use, visibly damaged or showing signs of tears or bites to avoid the danger of small parts being swallowed.

• For safety and hygiene purposes, replace the teat after 1-2 months use.

• Do not expose the teat to direct sunlight/ heat or leave in sterilising solution for longer than the stated time as this can damage the teat.

• Store hygienically in a dark and dry place.

• Do not dip the teat in in medicine!

• If the bottle/breast milk container is damaged on the inside (e.g. scratches), it should be replaced for reasons of hygiene.

• Keep all components not in use out of the reach of children. Note: NUK Bottles and Teats are compatible only with the corresponding product range (First Choice

or Nature Sense). NUK Product complies with EN 14350. Caution! Ignoring this warning can cause minor personal injury and/or property damage:

• Do not microwave bottles filled with feed or water (risk of explosion/product damage). Uneven heating may result in scalding!

• Never heat closed bottles as they may explode!

• Before each use, softly squeeze the teat vent and drinking hole to ensure they are open.

• Cooling down a plastic bottle that has been filled with hot liquid (> 80 °C) and sealed with the lid, could cause the bottle to deform permanently.

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

nvironment 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 dev ice 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

irectly 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

isturbances to maintain basic safety during expected service life are not provided. Note: The electric breast pump has no essential

eatures 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 (Co mité international spécial des perturbations radioélectriques - International Committee on Radio Interference). Warning! Portable HF communication dev ices (radio devices) (including their accessories, such as antenna cables and external antennas)27 should not be used at a distance of less than 30 cm (or 12 inches) to the parts and

pes 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. 4 Designation of Components and functional Elements (Figure A) 1 Lug for shoulder strap 2 USB port for charging (cover removable) 3 Pump unit 4 Tube 5 Protective cap 6 Filter (plus 1 replacement) 7 Tube connector plug 8 Tube connector on breast shield 9 Breast shield 10 Silicone cushion 11 Lip valve (plus 1 replacement) 12 Breast milk container 13 Mains adapter (breast pump must only be used with the mains adapter included in the delivery package) 14 USB cable 15 Feeding teat 16 Screw ring 17 Protective cap 18 Sealing disc 19 Stand 20 Shoulder strap Control buttons of the pump unit 21 Memory button 22 Change suction rhythm 23 Reduce suction strength 24 Increase suction strength 25 Pause button 26 Master power switch First Choice

Warning! To avoid the risk of elec- tric shock: Unplug mains adapter 13 from the wall socket before cleaning. Caution! To avoid damage, carefully clean the lip valve 11. We recommend just rinsing off the lip valve and boiling it to sterilise. Cle aning implements may lead to damage.

1. Dismantle the device as shown in figure B,

roceeding in reverse from 7 to 1. Warning! Never su bmerge the pump unit 3, the mains adapter 13, or the USB cable 14 in water, as this will damage the electrical con tacts.

2. Clean the following parts with warm

water and a little washing-up liquid (or NUK Rinsing Agent). Then rinse the parts in running water: 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.

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

Before sterilising, clean as described in the section entitled “5.1 Cleaning)”. Warning! R isk 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.29

• 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:

1. Use a NUK Steam Steriliser, following the

operating instructions of the device. Alternatively,

2. sterilise the parts in boiling water for 5

minu tes. Ensure there is sufficient water in the pan to avoid damage. Alternatively,

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

• If the power supply supplies a current

ess than 2 amperes, an error message will appear in the display when the pump is switched on and you will hear a beep. Nature Sense model display: Symbol 37 First Choice

• No further check of the power supply is made once the device is in operation.

Warning! Only the mains adapter included in the delivery package must be used for operation from mains power. To disconnect from the mains supply, unplug the mains adapter from the socket.

A power bank is not included in the delivery package. The power bank must provide an output current of at least 2 amperes. Otherwise, an error will be visually and audibly indicated when the pump is switched on. Use the USB cable 14 to connect the power bank with the USB port 2 of the pump.

7.3 Battery operation (Nature

Sense model only) If no mains adapter is connected, the device will run off the integrated battery. To this end, the battery must be adequately charged (at least 2 bars shown in battery charge symbol), so that at least one pumping session can be completed. The battery charge state is displayed by the

attery charge symbol 36. Fully charged (4 bars in the battery charge

mbol 36), the battery power will last for three full pumping sessions of 30 minutes

ach. Note: While connected to mains power or a power bank, the battery will also be charged during operation. 8 Operation

21. Clean the necessary components

imm ediately after completing your pumping session (see “5Cleaning and Sterilising“ on page28).

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 funct ion 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 uni t 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 s houlder 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.

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.

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

apid 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.33 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:

Alternatively, you can repeat the"stimulation phase" in order to stimulate your milk flow reflex anew. The amount of time needed to express milk

ill 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 req uirements. This means that the quantity of milk

oduced 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.

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

mportant 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! T o ensure adequate hygiene at all times: If your collected breast milk is not for immed iate 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

he 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 34.34 Caution! To avoid damage:

• When freezing breast milk, do not fill the

reast 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

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 mus t be disposed of and not refrozen. Warning! Risk of scalding and risk of destroying valuable nutrients: Do not use a microwave to defrost

reast 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

isk destroying the vitamins and other valuable nutrients it contains. There is also a risk of scalding for your baby. Always check the temperature of

our warmed up breast milk before feeding it to your baby.

1. To achieve the correct drinking

emperature 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.

2. Shake the milk gently before feeding so

that milk and milk fat are properly mixed again.

3. 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,

octor or pharmacist for detailed information about long-term storage.

• You can find more information about breastfeeding on our NUK website (www.nuk.com).

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 positioned If 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 allow more time to dry or use dry replacement filter (see “5.3Special cleaning of tube and filter“ on page29). Pump suction is weak Low battery power Check whether battery power is sufficient (see “7.3Battery operation (Nature Sense model only)“ on page30). Suction strength is set too low Increase the suction strength until you achieve the best results (see "Setting the suction strength" on page31). 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 “5.3Special cleaning of tube and filter“ on page29). Filter is wet Remove filter and allow more time to dry or use dry replacement filter (see “5.3Special cleaning of tube and filter“ on page29). Pump suction too strong Suction strength is set too high Reduce suction strength (see "Setting the suction strength" on page31).36 13 Technical Data The mains adapter included in the delivery and the breast pump form a medical electrical system in accordance with EN 60601-1. All devices in the ME system comply with the requirements of EN 60601-1 or EN 60950-1. Pump making strange noises Lip valve unable to cope with milk flow volume Reduce suction strength (see "Setting the suction strength" on page31). 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 Immediately switch off the pump unit and clean the tube and the filter (see “5.3Special cleaning of tube and filter“ on page29).
