2Assembly and installation
Check that no parts are damaged. If damage is found, contact Care of Sweden or your local
distributor before using the product. Do not use sharp objects when unpacking as it might damage
the product.
When using an overlay mattress (CuroCell®
OP10 or CuroCell® CX10):
1a. Place the overlay
mattress on the base
mattress. Secure the
mattress to the base
using the straps on
the corners of the
mattress.
When using a full replacement mattress
(CuroCell® CX15, CuroCell® CX16 or CuroCell®
CX20):
1b. Place the mattress
on the bed base.
Secure the mattress to
the bed using the
fastening straps on the
underside of the
mattress.
2. Hang the control unit on
the foot end of the bed or
place it on a level, steady
surface.
3. If the mattress is equipped
with a cable holder, place the
power cable in the cable holder by opening
the press studs, placing the cable in the gap
and closing the press studs again. Otherwise,
place the power cable so there is no risk of
stumbling over it, running over it with the bed
wheels, or getting it jammed when raising or
lowering the bed.
4. Open the lid on the air tube connector
(marked CPR) and connect it to the side of the
control unit.
5. A click is heard and
felt when correctly
connected. Secure that
both sides of the
connection are closed.
6. Check that the switch
on the side of the control unit is
set to ’0’ (off). Plug the power
supply into an approved and
easily accessible electrical
socket (100– 240 V).
7. Check that the power cable
has been correctly connected to
the control unit and that the correct power
supply has been used. (See section 9.1
Technical specification).
The correct P/N is shown on the label on the
power supply. The power supply is part of the
equipment and may not be replaced.
If the control unit has been stored in its
minimum or maximum storage temperature (-
25°C to 70°C), wait at least 1 hour before
starting it. This time is based on an ambient
temperature of 20°C.
Note!
•Make sure that the mattress is the correct size
for the bed.
•Make the bed with sheets.
•If an adjustable bed is used with a full
replacement mattress with fastening straps
(CuroCell CX15, CuroCell CX16 or CuroCell CX20),
the mattress should be fixed only to the moving
parts of bed.
•Check the cells and press studs to ensure they
are correctly assembled.
•The mattress should be
used lying in the lengthwise
direction on the mattress,
with feet at the end, market with the feet
symbol.

5
Note!
•When using a lift to place the user in the
bed and the head end of the bed is raised,
make sure that the user is not placed too
high on the mattress. Otherwise, there is a
risk of shear.
•When the alternating or pulsating
program is used and the head end of the
bed is raised, make sure that the user
and/or the mattress is not moving
downwards due to the movement in the
mattress. Also raise the foot end of the
bd
3Common operations
Following operations apply to CuroCell® M4,
CuroCell® A4 and CuroCell® IQ regardless of
which mattress that is used.
3.1 Sitting positioning in bed
When raising the head end of the bed into a
sitting position, always secure the user´s
position. To ensure the product functionality,
we always recommend to perform a hand
check (see section 4, 5 or 6 depending on the
pump and mattress of interest). This function
is recommended to use for short periods only.
For additional support, positioning pillows can
be used.
3.2 CPR (Cardipulmonary resuscitation)
In case of an emergency where CPR
(Cardiopulmonary resuscitation) is necessary,
remove the connection (marked ‘CPR’) from
the control unit
and leave the
lid open in
order to empty
the mattress of
air quickly.
3.3 Transport function
If the user needs to be moved in bed, either:
•Unplug the CPR connection, close the lid,
place the CPR connection at the end of the
bed and remove the control unit from the
bed. The mattress will retain air for at least
12 hours.
Or
•Remove the power supply from the wall
socket and leave the control unit hanging on
the bed during transport. The mattress will
retain air for at least 12 hours.
We recommend using this function for short
periods only.
3.4 Restart
If a restart is required, set the On/Off switch
on the side of the control unit to 0 (Off). Wait
for approx. 10 seconds and restart the control
unit.
3.5 Maximum pressure notification
When the function Maximum
pressure has been used for a long
time, the Maximum pressure diode
will blink. If the use is intentional, ignore the
notification.
3.6 Power failure
In the event of a power failure, unplug the CPR
connection, close the lid, place the CPR
connection at the end of the bed and remove
the control unit from the bed. The mattress
will retain air for at least 12 hours. Perform a
hand check to make sure the pressure of the
mattress is not too hard or too soft.

4Operation CuroCell® M4
Following operations apply only to CuroCell® M4 regardless of which mattress that is used.
Operation CuroCell® M4 (how to get started)
1. Set the On/Off switch on the side of the control unit to position 1 (On). See figure 1.
2. Use the weight settings to set a suitable air pressure.
3. The mattress starts to inflate. This takes about 20-40 minutes depending on the size of the
mattress. While the mattress is inflating, the “mute the information signal” and “information signal”
diode light up in orange. When these diodes goes out, the user can be placed on the mattress.
4. The pulsating mode setting is pre-set. If a different setting is desired, it can be selected when the
user is placed on the mattress.
5. When the user is placed on the mattress and the desired program is selected, the inner pressure of
the mattress is adjusted according to the selected weight setting. This takes about 10 minutes. During
this time, the diode above the selected program flashes. When the diode stops flashing, the mattress
is set and the inner pressure has reached the selected value.
6. Perform a hand check to ensure that the settings are correct.
7. If the mattress is too soft or too hard, adjust the weight setting.
8. Perform another hand check.
Figure 1.On/Off switch.
Note!
•Each time the system starts up, it will operate
as follows:
When using a mattress without an air safety
mattress (CuroCell® OP10, CuroCell® CX10 or
CuroCell® CX16), the control unit will adjust to
the set weight.
•When using a mattress with an air safety
mattress (CuroCell® CX15 or CuroCell® CX20),
the control unit always begins by completely
inflating the safety mattress, followed by the
other cells, and then perform an automatic
setting.
•When using a mattress with a safety mattress
in foam (CuroCell®CX16), the user can lie on
the mattress even when not inflated.
•When using a mattress with an air safety
mattress (CuroCell®CX15 or CuroCell®CX20),
this must be inflated before the user can lie on
the mattress. In both cases, the safety
mattress will carry the load when the orange
diode goes out.

4.1 Function
At start-up, the inner pressure of the mattress
must be set manually based on the weight and
height of the user. The mattress system
maintains the pre-set inner pressure regardless
of movement and position changes. This means
that when the user changes position, for
example, the mattress’s inner pressure must be
adjusted manually. The weight settings on the
control unit are used to change the inner
pressure.
4.2 Programs
There are three programs to choose from:
Constant low pressure (CLP) means that the air
pressure in all of the air cells is the same in the
whole mattress.
Alternating mode means that the air pressure in
the air cells are different and alternates
regularly after chosen cycle periods.
Pulsating mode combinates CLP with the
alternating function.
Chose program by pushing the button for the
program. We recommend the Pulsating mode
which is also the preset mode.
1. Constant low pressure mode
(CLP)
No cycle period is needed.
2. Alternating mode. The cycle
period can be changed according to
the user needs and requirements.
Choose between 10, 15, 20 or 25
minutes. The longer the cycle period, the slower
the alternations. We recommend a basic setting
of 10 minutes.
3. Pulsating mode. The cycle period
can be changed according to the user
needs and requirements. The longer
the cycle period, the slower the
alternations. We recommend a basic setting of
10 minutes.
4.3 Maximum pressure (caring
mode)
With this function, the entire
mattress is inflated and provides
firmed support. This function reverts to the
previous setting after approximately 20 minutes.
The function should be used when caring the
user, shifting the user’s position, or moving the
user in or out of bed. When the function has
been used for a long time, the diode will blink. If
the use is intentional, ignore the notification.
4.4 Seating function
The alternating mode switches to
pulsating mode when the seating
function is activated. A visible and audible
notification is generated when the seating
function has been active for two consecutive
hours, notifying that repositioning of the
individual may be necessary. The control unit
will also notify if an attempt is made to switch
on the system while seating function is active.
4.5 Panel lock
Press the Panel Lock button to lock or
unlock the control panel. The button
indicates when the panel has been
locked. The screen locks automatically if left
untouched for five minutes. This is to prevent
the settings being changed accidentally. To
unlock, press the button for 2 seconds.

4.6 Hand check (function control)
Hand check is performed to ensure that the
mattress system works properly and to ensure
that the weight setting is correct. Hand check
should be performed regularly; for CuroCell®
M4, we recommend once per work shift as well
as after installation of the system.
For manual systems hand check should also be
performed when moving from lying to seating
position in bed, in case of positioning changes
and when changing the comfort setting (and/or
the weight setting).
When using an overlay mattress system
(CuroCell® OP10 or CuroCell® CX10):
1a. Open the cover and identify a cell with less
air at the user’s sacrum. Insert a hand, with the
palm facing up, between the overlay mattress
and the underlying mattress. The hand is
inserted beneath the user’s sacrum (center of
mattress).
When using a full replacement mattress
(CuroCell®CX15, CuroCell®CX16 or CuroCell®
CX20)
1b. Open the cover and identify a cell with less
air at the user’s sacrum. Insert a hand, with the
palm facing up, between the top cells and the
underlying safety mattress. The hand is
inserted beneath the user’s sacrum (center of
mattress).
2. Ensure there is a gap between the user and
the underlying mattress so that the user does
not ‘bottom out’.
3. If you can feel the user’s sacrum resting in the
palm of your hand, the gap is too small. See
section 8 ‘Troubleshooting’.

Note!
Each time the system starts up, it will operate as follows:
•When using a mattress without an air safety mattress
(CuroCell® OP10, CuroCell® CX10 or CuroCell® CX16), the
control unit will completely inflate the main cells and then
perform an automatic setting.
•When using a mattress with an air safety mattress
(CuroCell® CX15 or CuroCell® CX20), the control unit always
begins by completely inflating the safety mattress, followed
by the other cells, and then perform an automatic setting.
•During the automatic setting, try to avoid larger
movements on the mattress. Otherwise, you will get a
notification on that the desired value could not be reached
within the time limit and the weighting must start over.
•When using a mattress with a safety mattress in foam
(CuroCell® CX16), the user can lie on the mattress even
when not inflated. When using a mattress with an air safety
mattress (CuroCell® CX15 or CuroCell® CX20), this must be
inflated before the user can lie on the mattress. In both
cases, the safety mattress will carry the load.
•Once automatic setting is complete, the control unit
switches to a basic setting of Pulsating mode (when
used for the first time) or to the previous setting. For

5.1 Function
The mattress system independently and
without manual adjustment controls the inner
pressure of the mattress according to the
weight, height, and position of the user. No
manual action needs to be performed to adjust
the inner pressure of the mattress. This
function works as follows:
1. At start-up, automatic setting of the inner
pressure of the mattress is always carried out
according to the weight and height of the user.
2. If the user moves noticeably or changes their
position, the system will independently control
the inner pressure of the mattress.
3. The system performs an automatic setting at
fixed intervals even if no significant changes
have occurred.
After automatic setting of the mattress inner
pressure, the system returns to the previously
selected program. At start-up, Pulsating Mode is
always pre-set.
5.2 Programs
There are three programs to choose from:
Constant low pressure (CLP)means that the air
pressure in all of the air cells is the same in the
whole mattress.
Alternating mode means that the air pressure in
the air cells are different and alternates
regularly after chosen cycle periods.
Pulsating mode combinates CLP with the
alternating function.
Chose program by pushing the button for the
program. We recommend the Pulsating mode
which is also the preset mode.
1. Constant low pressure mode (CLP)
No cycle period is needed.
2. Alternating mode. The cycle period
can be changed according to the user
needs and requirements. Choose
between 10, 15, 20 or 25 minutes. The longer
the cycle period, the slower the alternations.
We recommend a basic setting of 10 minutes.
3. Pulsating mode. The cycle period
can be changed according to the user
needs and requirements. The longer
the cycle period, the slower the alternations.
We recommend a basic setting of 10 minutes.
5.3 Maximum pressure (caring mode)
With this function, the entire
mattress is inflated and provides
firmed support. This function reverts
to the previous setting after 20
minutes. The function should be used when
caring the user, shifting the user’s position, or
moving the user in or out of bed.
5.4 Panel lock
Press the Panel Lock button to lock or
unlock the control panel. The button
indicates when the panel has been
locked. The screen locks automatically if left
untouched for five minutes. This is to prevent
the settings being changed accidentally.
To unlock, press the button for 2 seconds.
5.5 Comfort settings
The pressure can be
increased in two
steps depending on
the user’s comfort
requirements. This increase is made based on
the automatic setting in 5.1.
The selected setting is shown by a green light.
5.6 Hand check (function control)
Hand check is performed to ensure that the
mattress system works properly. Hand check
should be performed regularly; for CuroCell® A4,
we recommend once per work shift as well as
after installation of the system.
Note!
•When only parts of the mattress are
under load, for example, in the case of
amputees – it may be necessary to raise
the setting using the comfort settings.

When using an overlay mattress system
(CuroCell® OP10 or CuroCell® CX10)
1a. Open the cover and identify a cell with less
air at the user’s sacrum. Insert a hand, with the
palm facing up, between the overlay mattress
and the underlying mattress. The hand is
inserted beneath the user’s sacrum (center of
mattress).
When using a full replacement mattress
(CuroCell® CX15, CuroCell® CX16 or CuroCell®
CX20)
1b. Open the cover and identify a cell with less
air at the user’s sacrum. Insert a hand, with the
palm facing up, between the top cells and the
underlying safety mattress. The hand is
inserted beneath the user’s sacrum (center of
mattress).
2. Ensure there is a gap between the user and
the underlying mattress so that the user does
not ‘bottom out’.
3. If you can feel the user’s sacrum resting in the
palm of your hand, the gap is too small. See
section 8 ‘Troubleshooting’.

5.13 Notifications
Different notifications exist based on
how serious the warning is. With a
malfunction or an error, a notification
will be given by way of a flashing warning
triangle. To mute the warning signal, press the
mute button.
When a notification
occurs, the current cycle
time diode will turn off
and a notification code is shown on the four
different cycle time diodes (10, 15, 20, 25). To
read the cycle time during the error notification,
unlock the control panel.
5.14 Maximum pressure notifications
See 3.5
5.15 Table of notifications
Information about each notification is shown in
the notification table:
Notifications from 1-10 are both audible and
visual. The error code will be displayed until the
error has been rectified. If the mute button is
pressed the audible warning will crease for a
period of 5 minutes and will return until the
error has been rectified. The notifications 11-13
have no audible alarm. The error code is shown
until the system is restarted.
Note!
•Make sure that the mattress system is
filled, which is shown by a green light
from the diode, before performing a
hand check.
•How to perform a hand check depends
on which mattress is used.

6Operation CuroCell® IQ
Following operations apply only to CuroCell® IQ regardless of which mattress that is used.
Operation CuroCell® IQ (how to get started)
1. Set the On/Off switch on the side of the control unit to position 1 (On). See figure 1.
2. The mattress starts to inflate. This takes about 20-40 minutes depending on the size of the mattress.
While the mattress is inflating, the “silent information signal” and “information signal” diodes light up in
orange. When these diodes goes out, the user can be placed on the mattress.
3. The control unit sets the inner pressure of the mattress according to the weight, length, and position
of the user. This takes about 20-30 minutes. During this time, the diode above the “check symbol”
flashes. When the
diode stops flashing, the mattress is set and the inner pressure has adjusted according
to the user.
4. Perform a hand check to ensure that the settings are correct.
Figure 1. On/Off switch.
Note!
•Each time the system starts up, it will operate as
follows:
When using a mattress without an air safety
mattress (CuroCell® OP10, CuroCell® CX10 or
CuroCell® CX16), the control unit will completely
inflate the main cells and then perform an automatic
setting.
•When using a mattress with an air safety mattress
(CuroCell® CX15 or CuroCell® CX20), the control unit
always begins by completely inflating the safety
mattress, followed by the other cells, and then
perform an automatic setting.
•During the automatic setting, try to avoid larger
movements on the mattress. Otherwise, you will get
a notification on that the desired value could not be
reached within the time limit and the weighting must
start over.
•When using a mattress with a safety mattress in
foam (CuroCell® CX16), the user can lie on the
mattress even when not inflated. When using a
mattress with an air safety mattress (CuroCell® CX15
or CuroCell® CX20), this must be inflated before the
user can lie on the mattress. In both cases, the safety
mattress will carry the load.
