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.
1. Place the mattress
on the bed base.
Secure the mattress to
the bed using the
fastening straps on the
underside of the
mattress.
If the mattress is used on an adjustable bed, the
fastening straps at the middle of the mattress
shall be fastened at the bed’s unmovable parts.
The straps at the head end and foot end shall be
fastened in the parts of the bed that may be
raised or lowered.
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
Technical specification, section 11).
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
(min -25°C, max 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.
•Check the air cells to ensure they are
correctly assembled.
•The mattress should only be used lying in
the lengthwise direction on the mattress
with the feet at the end, marked 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 bed.
3Common operations
Following operations apply to the Cirrus system
regardless of which control unit 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 or 5 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.
3.7 Automatic Setting
The mattress system regulates the mattress's
internal pressure independently and without
manual adjustment to different values based on
the user's weight and position. No manual action
is required to affect the internal pressure of the
mattress. This function works in the following
three ways:
1. The control unit carries out an automatic setting
immediately after switching the system on.
2. During usage, if any significant change occurs,
the control unit will perform an automatic setting.
3. When in use, the control unit will carry out
automatic settings at fixed intervals to ensure
correct control of the pressure in the mattress at
all times.
Once the automatic setting has completed, the
control unit will start in the Pulsating mode.

CuroCell® A4 Cirrus

Note!
•
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 weighing must start over.
•
The mattress must be inflated before the user
can lie on the mattress.
•
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.
4Operation CuroCell® A4 Cirrus
Operation CuroCell® A4 Cirrus (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 minutes depending on the size of the mattress.
While the mattress is inflating, the ”mute the 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 pulsating mode setting is pre-
set. If a different setting is desired, it can be selected when the
user is placed on the mattress.
4. The control unit sets the inner pressure of the mattress according to the weight, length, and
position of the user. This takes about 20 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
adjusted according to the user.
5. Perform a hand check to ensure that the settings are correct.

4.1 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.
4.2 Programs
There are three programs to choose from:
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.
Choose 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. 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.
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 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.
4.4 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.
4.5 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.
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.

6Product description
6.1 Control unit (A4/IQ)
CuroCell® A4 and CuroCell® IQ are automatic air mattress systems used as an aid to prevent and
treat pressure ulcers/pressure injuries. The automation means that the control unit’s built-in
sensors use software to adjust the inner pressure of the mattress according to the user’s weight,
height, position, and change in position. This means that no manual action needs to be performed
to adjust the inner pressure of the mattress to conform to the user.
With CuroCell® A4 there are three programs to choose from. CuroCell® IQ uses the pulsating
mode which is a combination of the alternating mode and CLP mode.
Any of these two control units are compatible with the CuroCell®Cirrus mattress.

cloth and mild cleaning solution for this
purpose: such as alcohol with or without
tenside surfactants, oxidizing solutions, chlorine
max 1 % or hydrogen peroxide max 1,5 %.
MATTRESS COVER
Covers can be wiped off with a mild
cleaning solution for this purpose such
as: alcohol with or without tenside
surfactants, Isopropanol 70 %, oxidizing
solutions, chlorine max 1 % (max 10% for cover
Stone) or hydrogen peroxide max 1,5 %.
Excrement and blood stains must be removed as
soon as possible using cold water. Carefully
follow local instructions and the instructions for
