1 KANMED Baby Warmer - Quick instruction
Always leave the unit switched on so that it is ready for the next baby!
Refer to the Users manual whenever in doubt. Se also the Baby Warmer Video “Handling Instructions”
Filling the water mattress
1. Use the filling tube to fill the water mattress with warm water (about 350C).
2. Fill to the level mark. Check by standing the water mattress upright. If the bed is to be tilted please read
chapter 3 Water Mattress, in the users manual.
3. Add one complete bottle of KANMED anti algae, preferably via the filling tube.
4. There must be no air in the water mattress. Place the water mattress on a flat surface. Grip the open mattress
nipple to lift the mattress up a bit and press all air bubbles out. Lower the nipple and close it.
Inserting the Heating Pad and Nest
1. Place the water mattress on a flat surface to insert the heating pad.
2. Turn the water mattress upside down and insert the Heating Pad in the pocket with its printed text towards the
water.
3. Turn the water mattress over again.
4. Insert the water mattress with heating pad into the nest pocket. Use the opening in the head end of the nest to
assist in fitting the Nest to the water mattress.
Preparing the bed
1. Ensure that the bed has holes in the bottom.
2. Place the Baby Warmer on the cot mattress.
3. Place the Baby Warmer in the KANMED Baby Bed or any other suitable bed.
4. Protect the Nest with a sheet that is soft but not too thick.
Connecting the Control unit
1. Connect the Heating Pad at the back of the Control Unit. Don’t over tighten.
2. Connect the power cable at the back of the Control Unit and switch it on.
3. Hang the Control Unit in a safe place where it can be seen.
4. Press the start button on the front panel and observe that it starts at 370C after a short self test.
Placing the baby
1. Only when the desired temperature is reached, you can place the baby in the nest.
2. Position the lightly dressed baby (diaper, long arm T-shirt, bare legs and a cap on very small ones) on its back
in the nest.
3. Adjust the nest size by pulling the string. Hide the cord under the mattress.
4. Cover the baby with suitable cover, such as 1-3 layers of cotton blankets.
Temperature setting
1. All babies are individuals and their temperature must be controlled frequently until you are familiar with the
baby’s reaction to the water temperature. Overheating is often caused by covering the baby too much.
2. 370C is a good starting temperature for slightly hypothermic babies and for babies weighing less than 1000g.
3. 36.50C is the most common temperature for babies weighing more than 1000g
4. As the baby’s weight increases, the temperature is primarily controlled by changing the amount of blankets that
cover the Baby and secondly by changing the temperature in 0.50C increments.
5. When the lightly dressed and covered baby is maintaining body temperature with a water temperature of about
35.5 - 360C, then the baby is most often ready for a standard cot that has no warming.
Maintenance
1. Wash the nest at maximum 900C. Preferably 600C. Dry tumble it. KANMED recommends you to change the
Baby Nest once a year.
2. Surface disinfect the water mattress and the heating pad
3. Change water every 3 months and add a new bottle of anti algae.
4. See the user’s manual for further maintenance instructions and periodical safety checks.

Avoid bending the Heating Pad.
The design and construction of the Heating Pad has reduced magnetic and electrical fields to normal
background levels and thereby making them harmless.
The voltage to the Heating Pad is SELV (24V DC, Safe Extra Low Voltage).
See technical data for information about warming up times.
Explanation of the drawings on the Heating Pad
Please make them available while reading this
1. Heating Pad BW-50-002 may only be connected to Control Unit BW-50.
2. Never place a baby or a child directly on the Heating Pad.
3. The Heating Pad must be inserted in the pocket under the Water Mattress.
4. The correct amount of water is obtained by filling the Water Mattress to the level mark.
5. The Heating Pad must be inserted into the pocket of the Water Mattress with its illustrations facing
the Water Mattress. This is best done if the Water Mattress is placed upside down on a flat surface.
6. The Heating Pad and the Water Mattress shall not be exposed to sharp objects.
7. For cleaning and disinfecting see user’s manual.
8. The Heating Pad must be stored flat or rolled with a diameter of at least 10 cm (4"). Do not fold

User Manual BW-50-070/10

The Water Mattress
When filled to the level mark it contains about 4.5 litres of water. If you plan to tilt the bed then add 2 cm
of water. Fill by using the filling tube. Add Anti Algae every 3 months. Water molecules diffuse through the
material. This is normal. Therefore the water level should be checked regularly
NOTE: Do not tilt the Water Mattress if the temperature must be higher than 37OC. The very
sensitive over temperature circuit can alarm and switch off the warming.
When tilting during warming up, too little water will make the over temperature alarm go off.
Explanation of the drawings on the Water Mattress
9. The level mark on the Water Mattress indicates standard water amount. If tilting is required please
add 2 cm more water.
10. Place the Water Mattress in an upright position and fill it with the enclosed Filling Tube. When the
desired level has been reached, add Anti Algae carefully through the filling hole or via the Filling
Tube. Follow the caution instruction on the Anti Algae package. NOTE: Air pressure may build
while filling. Interrupt filling and release air if necessary.
11. Remove air bubbles, Very Important. Place the Water Mattress on a flat surface and lift the filling
hole 5 to 10 cm upwards. Press the air bubbles towards the hole repeatedly until all major air
bubbles are expelled.
12. Lower the filling hole while pressing the Water Mattress so that no air enters and insert the plug.
13. Turn the Water Mattress upside down and insert the Heating Pad in the pocket.
14. The Water Mattress and the Heating Pad is inserted into the KANMED Baby Nest.
The KANMED Baby Nest
Different types of KANMED Baby Nests are available. Please check with your supplier or on internet
www.KANMED.se
The KANMED Baby Nest is intended to prevent the baby from rolling off the water mattress, to facilitate
correct positioning and to create a tight and cosy environment around the baby.
By pulling the strings one can adjust the collar from being wide open and flat to become a tight raised wall
around the baby. The Baby Nest consists of a bag into which the Water Mattress and Heating Pad is
inserted.
Note: Check the Baby Nest regularly for damages. To reduce the risk of a nest splitting during washing we
recommend that the nest is used for only one year.

4 Description of functions
Start and self test
Every time the Control Unit is switched on it performs a self test of all functions and the internal safety
circuits. (See chapter 10 for a detailed description of the self test). If the Control Unit does not detect any
faults, the warming will start automatically at a factory pre-set temperature of 37 OC.
That the Unit is warming is indicated by a temperature lamp being lit. (Wait about 10 seconds after start)
If the unit do not self test exactly as described in this manual- then you must not use it!
Warming can only start if no faults are detected.
Temperature indication and selection
The actual water temperature is indicated by a blinking lamp and the selected by a constantly lit lamp.
That the selected temperature is reached is indicated by a constantly lit temperature lamp.
The temperature lamps have different colours as described below.
Lamp Colour Temperature range Comment Symbol(s)
Green 35 - 37 oC Selected by pressing the temperature
button
Yellow 34, 34.5, 37.5 and 38 oC Can only be selected if the temp lock
key is pressed and hold in at the same
time
+
Red 20- 30 and 39-42 oC Only for indication
Alarms
Description and checks of the function of alarms is found in the technical section.
Stop the acoustic alarm by pressing the alarm button or switch the unit off by pressing the Start/ Stand By
button. Only ∆Tcan be cancelled for 10 minutes by pressing the alarm button.
Try to rectify the cause for an alarm (see section trouble shooting) and switch on the unit again.
If the alarm still goes on - contact a qualified technician.
5 Getting ready for the baby
Please follow the Quick Start instruction on page 3.
Ensure that all parts are available and in good condition.
See also the video “Handling Instructions”
Always place the KANMED Baby Warmer on the ordinary mattress of a baby cot or any other surface that is
heat insulating.
6 Daily use and practical hints
Always leave the unit switched on, even in the storage room, so that the water mattress is warm and
ready.
Delivery Wards
•Use it for children that for different reasons have lost heat after the delivery.
•Low birth weight or premature babies that do not need all the resources of an intensive care
department can thanks to the KANMED Baby Warmer be kept with the mother in the ward.
•In rooms with low temperatures.
Transport of babies inside the hospital
If the child is normally covered and in a standard cot, the water temperature will only drop about 1.50C
per hour when the power is disconnected.

User Manual BW-50-070/10
Page 9 of 16
When transporting in an ambulance (ground or air)
The KANMED Baby Warmer can be powered from a 12 - 24 Volt battery. During transport it will keep the
baby warm and provide a soft chock absorbing support.
NOTE: When powering with 12V battery the warming capacity is reduced, see technical section. Note that
local restrictions and rules apply for transport of patients.
In Maternity Wards it allows more children to stay with their mother and will save costs.
"In between" babies, that are babies between 2000 and 2500 gram, born around pregnancy week 35 - 38,
are often not capable of maintaining a normal body temperature during their first days after birth. KANMED
Baby Warmer keeps them at normal temperature and allows them to stay with their mothers.
Uneasy, stressed and screaming babies can often find a soothing and relaxing environment on the warm
water mattress thereby relieving the staff or mother.
Neonatal intensive care departments
KANMED Baby Warmer can be used to reduce the time the baby needs to spend in an incubator.
KANMED Baby Warmer can replace the incubator when the baby is mostly in need of the warming.
Vital signs monitoring can easily be continued in the KANMED Baby Warmer and the KANMED Baby Bed
The KANMED Baby Warmer can also be used inside an incubator to help obtain correct body temperature,
especially in older single wall units. This has not been tested by KANMED and is the sole responsibility of
the hospital.
NOTE: The function and temperature regulation of the KANMED Baby Warmer is not influenced by the
incubator.
Try it for children in need of a soft warm support, for instance children suffering from hydrocephalus,
fractures or headaches after delivery with a forceps or a suction device, colicky pains, etc.
NIDCAP, Developmental Care and Kangaroo care
In these treatment forms the sleeping and rest as well as positioning of the baby plays an essential role.
The warm soft water mattress resembles the warmth of a mothers skin making the KANMED Baby Warmer
the ideal tool to ensure quality sleep. Kangaroo care is encouraged in open systems.
Photo therapy
KANMED Baby Warmer is very suited for Photo therapy by using an overhead lamp and especially for new
blue lights that do not give any heat.
