1.7 Evacuation instructions
Evac is a mattress cover with a built-in function for
evacuation of bed-bound users. In case of fire or other
emergency, there is no time to think about what to do next.
Therefore, it is very important that the safety equipment, as
well as the evacuation procedures, are well planned and
known in advance.
The Evac cover is equipped with three handles on the head
and foot end. On the sides, there are handles with velcro
straps. These straps are to be used to fixate the user to the
mattress before commencing the evacuation. The straps are
folded in the protective pockets on the side of the mattress
with the ends sticking out to ensure that they are easy to pull
out.
Evacuation instructions
Down from the bed
• Inform the user about what will happen.
• Lower and lock the bed in position.
• Disconnect the tubes from the control unit.
• Pull out and fasten the velcro straps.
• Use the outer handles at the foot end of the mattress and turn the
mattress out from the bed.
• Slowly pull the user down on to the floor.
On an even surface
• Pull on the outer handles at the foot end
of the mattress.
• Working position should be a little bit
leaning back.
Down the stairs
• Walk backwards until the main part of the mattress has slide pass
the top stair.
• Turn the back to the user and look in the moving direction.
• Hold one hand on the stair handle and
pull with the other hand
on the middle handle of the mattress.
• Walk down the stairs. It is important to
maintain speed, without running.
Training/practise
To bear in mind when training.
Pulling down from the bed:
• The user in the bed should not be at the very top of the mattress.
There could be a risk of hitting the head in the bed when pulling
down.
Pulling in the stairs:
• Start with pulling an empty mattress down the stairs, in order to
practice the technique.
• When training with a person on the mattress, a string or rope can be
fasten in the handles at the head end. Another person can then walk
behind the mattress and help out if problems should occur.
• It is advisable to practice in the same stairs where an evacuation can
be necessary.
General:
• The main purpose of the training is not to reach high speed, but to
learn the correct technique.
Training covers
• Because of the heavy strain on the equipment when evacuating,
always check the seams and handles at the end of training. We
recommend that equipment used for training is marked with
“Training equipment” and is only used for this purpose.
Explanations
• If the velcro straps are not used, there is a risk of the user
sliding/rolling down from the mattress.
• Pulling at the foot end reduces the strain on the puller, which means
faster and safer evacuation is possible.
• Pulling in the stairs is the most difficult part of the evacuation and
should be practiced extra carefully.
• The arms of the user shall be inside of the velcro straps. This way
reduces the risk of the user grabbing hold to something out of fear.
NOTE!
When using wider mattresses, make sure that the evacuation
routes are clear (size of doors etc.). Responsible personnel
have to ensure that the evacuation can be performed safely. To
ensure proper function of the Evac cover, it is important to
regularly check the quality of the mattress. Check for damages
that could cause problems when evacuating.
WARNING!
Person to perform an evacuation needs to have the necessary
training. Always check the equipment, cover and mattress
before commencing, to make sure an evacuation can be
carried out safely. It is the user’s responsibility to ensure that
it is safe to use for evacuation.

When unpacking, check that no parts are damaged. If any damage is found, contact Care of Sweden or your local distributor
before using 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.
Note:
•Make sure that the mattress is the correct size for the
bed.
•Make the bed with sheets for added comfort.
•If an adjustable bed is used the mattress should be fixed
only to the moving parts of the bed.
•Check the cells and press studs to ensure they are
correctly assembled.
2. Hang the control unit on the
foot end of the bed or place it
on a level, steady surface.
3. 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. If the cable
holder is not used: 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
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 must be 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.
2. Assembly/installation
.
NOTE:
.
Do not hold the 12 V plug on the power supply while touch-
ing the user.
Plug the power supply into an easily accessible socket if
there will be a need to unplug the power supply and com-
pletely cut the power to the control unit.

7
3.1 Start
1. Set the On/Off switch on the side of the control unit to position 1 (On).
2. Air will start to be pumped into the mattress. During the inflation
period, the mute diode and the notification diode to the right will
remain orange. When the orange lights are extinguished, the mattress
system is fully inflated.
3. The diode over the checkmark will blink during the inflation. Depending
on its size, it takes approximately 20–30 minutes for the mattress to
inflate fully.
4. When the green diode over the checkmark is constant, the system has
adapted the settings to the user’s individual needs and the system can be taken
into use. This takes approximately 20-30 minutes.
3. Operation
NOTE:
•During the automatic setting, try to avoid larger movements on
the mattress, otherwise, the automatic setting time will be
extended.

3.2.1 Automatic Setting
The control unit is equipped with a function that
automatically sets the pressure based on the user’s weight,
posture and position. 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.
3.2.2 Programs
CuroCell®IQ Cirrus is preset with a Pulsating mode, a
comfort mode that combines Constant low pressure
(CLP) with Alternating mode. A cycle period of 10
minutes is default.
3.2.3 Maximum pressure (caring mode)
With this function, the entire mattress is
inflated and provides firmed support. This
function automatically reverts to the
previous setting after approx. 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.
3.3 Hand check (function control)
The hand check is used to ensure that the mattress is
working properly. This must be performed regularly; we
recommend once per shift, or every eight hours.
Open the cover and insert a hand between the upper cells
beneath the user’s sacrum (center of the mattress). Check
to ensure that there is a gap to the underlying surface so
that the user does not ‘bottom out’. If you can feel the
user’s sacrum resting in the palm of your hand, the gap is
too small. Make a new automatic setting or see section 8
Troubleshooting.
3.4 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 3.3). For additional support, positioning
pillows can be used. We recommend that a sitting position
only shall be used for short periods of time.
3.5 CPR (Cardiopulmonary 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.
3.6 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.
The notification code is shown on the
four different diodes above the wrench
symbol. For more information about
the different notification codes, see section 3.6.1.

10
3.6.1 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.

7.1 General
The CuroCell® IQ Cirrus hybrid mattress is a medical
device, in accordance with Medical Device Regulation
MDR (2017/745), that is used as an aid in preventing and
treating pressure ulcers/pressure injuries. For this reason,
we recommend that the control unit be regularly serviced
and inspected to maintain functionality and performance.
Like other technical devices, a control unit that is properly
cared for works better and lasts longer.
Servicing and maintenance must always be performed by
Care of Sweden or one of its authorized technicians. Only
use spare parts that have been approved by Care of
Sweden. Use of non-approved spare parts invalidates the
warranty. For more information, see the CuroCell® IQ
Cirrus service manual.
Faults and defects regarded as warranty faults are fixed
free of charge.
A warranty claim must be submitted to Care of Sweden be-
fore the product is returned
After the product is used, check that:
1. The power cable and power supply are undamaged.
2. The connecting tubes (marked CPR) on the side of the
control unit are positioned correctly and not leaking.
3. The hygiene cover is intact and the cover and cells are
correctly assembled.
4. No tubes or connectors are damaged or jammed.
Contact Care of Sweden or your local distributor if any spare
parts are required.
7.2 Replacing the air filter
Before any maintenances are done, make sure that the
control unit is turned off. Services shall not be done while
using the product.
7. Maintenance
To replace the air filter:
1. Loosen the small protective plate on the rear of the
control unit using a size T10 Torx screwdriver.
2. Remove the filter from the holder.
3. Place the new filter in the holder with the pink side facing
outwards. Put the protective plate back in place and secure
using the screws.
If the control unit is used in a
very dirty environment the
filter should be checked regularly.

16
Problem Solution
The control unit does not
start
Check that the power supply has been connected to the mains supply. Check
that the LED on the power supply is showing green.
The user is ‘bottoming out’ Restart the control unit. See section 3.9. The control unit will initiate an automatic setting. Wait until the
automatic setting is complete.
Perform a further hand check (see section 3.3). If the gap is still too small, raise the comfort setting in
stages.
If the problem keeps occurring, contact Care of Sweden or your local distributor.
The mattress moves around Check that the mattress is fastened to the bed frame with the straps underneath (two at the head end and
two on each of the long sides).
Some cells have less air This is normal with a Pulsating or Alternating mode, as the air supply switches between alternating cells
for a predetermined cycle period (one cycle = 10 minutes).
The control unit makes a
noise; vibrations can be
felt
Check how the control unit is hung on the bed. Resonance can occur, vibrations are felt in parts of the bed.
Remove the control unit and listen to see whether this makes a difference. Can be resolved by putting the
