1 Foreword
Dear client,
you are now reading the user manual of the arsos® plus therapeutic support system of
ADL® GmbH.
arsos® plus is a multi-cell foam mattress with combined air-foam-cells. This air-foam
technology enables the mattress to adjust itself to the weight and feeling of comfort of
the patient by means of air support. The functions are based upon known reliable mecha-
nisms. On the one hand, it is a soft foam mattress with reinforced edges. On the other
hand, arsos plus is a static air filled mattress with a 21 cm safety soft foam mattress,
which prevents the patient from sinking to the bed base level in case of system failure.
To be operated with alternating pressure, the soft foam mattress is connected to the
alternating pressure power unit dexos light® wdm. The range of indications is extended by
a wide variety of diseases. This modular system combines advantages concerning safety
aspects and therapeutic purposes.
We are addressing the health professionals as well as the end users. Before the utilization,
please keep in mind that the first set-up is to be done by an instructed person. The end
user should also receive a briefing and read the entire user manual if used long-term.
With writing this user manual, the product management of the ADL GmbH has set itself
the goal to create a good and understandable aid and guidance to maximize the use of
the system. If, nevertheless, questions remain, please ask your provider for direction and
assistance, or contact ADL GmbH in Amt Wachsenburg directly.

2 Safety instructions
The system may not be used in presence of open flames, heaters et cetera. Protect the
equipment against humidity. Operate it only in dry areas. No combustible gases or liquids
may enter into the system.
EXPLOSION DANGER!
Warning! Note! The compressor is energized as soon as the power supply plug is put in.
Before opening the housing of the compressor, please unplug the power plug. Repairs must
be performed only by qualified technical personnel. The compressor may only be used for
its purpose. Please double check daily that the system is functioning flawlessly. In case
of damage to the compressor, the power supply plug must be unplugged immediately.
The damaged power supply cord should be replaced immediately. Only room temperatu-
res of 0 – 35 °C provide assurance to good compressor operation. Only use the system in
dry rooms. A multi-cell anti-decubitus-system does not replace the manual positioning
support from the nursing staff. Do not remove cells from the system (except for repair). If
applicable, batteries and accumulators must be disposed of properly. They do not belong in
the household waste!
Obligation to report:
There are legal regulations in the EU that mandate the patients and users to report any
product defects or unwanted side effects that worsened the patient’s state of health while
using the medical product. Immediate reporting to the manufacturer and the national
bureau is mandatory.

4 Introduction
The arsos® plus + dexos light® wds is a mattress replacement system, which means no
additional treatment nursing mattress is required. The system is suitable for patients with
a body weight of 40 – 150 kg. (Please note that these weight indications are applicable
for patients in a laying position. Other positions will result in a different weight distribution.)
The core of soft foam adapts to the shape of the human body which results in maximum
surface support and maximum pressure relaxation. The reinforcements of the foam edges
are an advantage for the sense of feeling and mobility of the patient. The ‘bottoming out’
of the patient onto the bed base is prevented by the 21 cm foam core of the arsos plus-
module.
This also helps to ensure compliance and conformity to DIN EN 1970:2000 because even
with full air pressure in the cells, the safety function of the bed rails remain unchanged. In
every instance, the standard DIN EN 1970:2000 must be complied with (view page 7).

6 Installation and setting up the mattress
Remove the existing nursing mattress.
Put the arsos® light mattress on the bed base frame and fasten it with the fixation
straps to the bed (to the “up and down” moving parts of the bed). If not properly
attached to the bed this can result in damage to the bed and mattress.
Place the mattress in such a way that the tubes are located at the foot end of the
bed.
Check the CPR function. It must be locked. For systems with a screw cap, it should
be in horizontal position when closed; in systems with a plug closure, ensure all
plugs are firmly in the socket.
The dual stretch and breathing cover made of polyurethane is to be fixed to the
base with the double-sided zipper.
Link the connector of the mattress to the pumping unit. The connector must give a
clear clicking sound.
Please note: Occasionally check the O-rings from the connector. To disconnect the
connector from the power unit without damaging the construction, press both
springs at the connector with your thumb and pointing finger before pulling it out.

Plug in the power cord und turn on the unit. The unit is preinstalled. When the display
lights are lit, the unit is operational. The power unit is pre-adjusted, so without the
need of selecting a certain level, the pressure in the system builds up to between
the minimum and maximum pressure levels. The unit starts up in alternating mode
with a 5-minute cycle. After half an hour, the system is inflated, and the patient can
be placed on the mattress.
The person lying on the mattress should always be placed to reach maximum contact
surface. This will reduce the pressure at the patient’s skin to a minimum. It is impe-
rative to check the pre-adjustment with a “hand check”. Try to move your hand under
the knee-joint, the lumbar and the neck lordosis to check if supporting material is
present. When pressure is too high, there will be a lack of supporting material in
those areas. The pressure must be reduced at the power unit. If the pressure is too low,
the “hammock effect” takes place. The patient’s buttocks are sinking to the bed base
level (view page 10).
You must attach the bed mount to the power unit before placing it to the back of the
bed. Slide the mount into the attachment at the bottom of the power unit.
Make sure that the air hoses are not bend or pinched in.
Turn on the system by pressing the power button .
The red alarm light will blink, and the system will begin to fill up with air (the
light will turn off automatically after this step). The filling process with arsos® plus
takes approximately 15-20 minutes.
The red alarm light should cease when the mattress is strained. When a certain level
of pressure is reached over a longer time, such as 2 minutes, the red alarm light will
blink constantly. That means the system should be checked for leakage (also view
page 10 under troubleshooting). A short flashing of the alarm light is of no impor-
tance. In addition to the visual alarm function, the unit has an acoustic alarm, which
activates automatically after a certain time period. By pressing the alarm button ,
the acoustic alarm can be switched on or off.

The optimum pressure can be set by pressing the pressure control button . The
scale is divided into eight setting options. If one diode is lit, the mattress has the
lowest possible pressure; if all eight diodes light up, the mattress has reached the
largest possible pressure (view table below on page 9). The adjustable pressure is in
the range of 5 and 40 mbar. After switching on the unit, the initial pressure is in the
scale center, which corresponds to about 20 mbar. An optimal setting of the system
must be checked by the “hand check”. The sinking behavior of the patient does not only
depend on his or her weight but also on the body stature. Try to move your hand under
the knee-joint, the lumbar and the neck lordosis to check if supporting material is
present. When pressure is too high, there will be a lack of supporting material in
those areas. If the patient is sinking in too deep, the “hammock effect” takes place,
which should be avoided (view page 10).
When pressure is too high, there will be a lack of supporting material underneath the
cranial lordosis of the body. In this instance, reduce pressure by pressing once or
several times the left pressure control button .
If pressure is too low (“hammock effect), press once or several times the right pressure
control button .
Each time you change the pressure level, you must wait for the set cycle to be done
until the new pressure can be reached. Then you can check the contact area again.

8 CPR-Function
Please make sure that the CPR flap (Cardiopulmonary Resuscitation) is always closed.
This CPR flap is located on the head side of the pad and is equipped with a red flag with
the inscription CPR. To check the CPR closure, open the cover of the pad. The lid of the
CPR should be tightly closed. To do this, the lid must be pressed firmly into the CPR
base. When lowering the bed rail, avoid accidentally opening the CPR closure.
In an emergency, the system is vented by jerkily pulling on the CPR flap. The patient lies
on the firmer foam after about 30 – 60 seconds. Please note that the Cardiopulmonary
Resuscitation cannot be performed on foam mattresses. The patient must lie on a solid
surface (e.g. a special resuscitation board).

9 Settings
The system can be switched to static mode by pressing button which is the middle
blue button on the right edge of the control panel. The display changes to the green
diode (static). “Static“ means that all cells of the pad are being filled with air and increase
to the set pressure value. It should be noted that due to the pressure distribution on
all cells, the maximum pressure is reduced by one or two scale points to ensure the
proper positioning. As long as the right position for the static has not been reached,
the green light diode flashes. The diode is lit permanently in the static position.
To turn off the static function, press button again. The display changes again to
the blue diode (alternate). “Alternate” means that the system is back in the alternating
pressure function. Now 2 out of 3 air chambers are filled with air, and the third
remains without pressure. Any changes made in the static function must be reversed.

Furthermore, the cycle time can be changed on the power unit. The adjustable range
is between a minimum of 5 and a maximum of 20 minutes. By pressing button ,
cycle time can be changed from the default value of 5 minutes in equal steps of 5
minutes to a maximum of 20 minutes. The cycle time is the time that is necessary for
the system to inflate and deflate the 3 air chambers.
The alarm has two modes. The basic setting is both the visual and acoustic alarm,
meaning that the red alarm light is blinking, and a beeping signal is audible. When
pressing the alarm button for approximately 5 seconds, the acoustic signal is switched
off. The switch-off is confirmed by a beep signal. Only the visual alarm is activated now,
the red alarm light lights permanently in case of emergency. The acoustic alarm can be
reactivated by pressing the power button or the alarm button .
Please note: During the initial setup, the acoustic alarm will only be activated after
30-40 minutes to prevent the acoustic alarm during the filling process. When using
the lowest possible pressure of 5 mbar, it is possible that the alarm starts. When the
alarm sounds for more than 1 minute, it is advised to check the system for leakages.

unintentional changes to the set values. The key lock is released by simultaneous
pressing the following buttons (alarm button & pressure button – or +).
After this, the settings can be changed.
2. Brightness of the display
The brightness of the display can be set in 3 modes with
the key combination alarm button and static/alternate button . The initial
setting is the brightest display. The display dims when pressing the key combination.
3. Power failure alarm
When the power supply to which the unit is connected fails,
there is a power failure alarm and the red alarm light flashes. The acoustic alarm
can be disabled with the alarm button or the power button . When the power
supply is restored, the alarm will also be disabled.
4. Memory function
The unit has a memory function. This means, when the power is interrupted, the
unit will remember the set values up to about 24 hours.
5. Reset function
By pressing the alarm button and the cycle button , the device can be put
back to factory settings. All previous settings are lost. The factory settings are
alternating pressure mode with pressure at 20 mbar, cycle time at 5 minutes,
audible and visual alarm.

(only possible with appropriate equipment)

6. Care function
When taking care of a patient, you have the option to activate this function by
pressing the static button for about 3 seconds. The alternating pressure system
switches now to the patient care function, which is indicated by the flashing of
the active cycle display and the green display for static. The alternating pressure
system is now changing to the static setting with a maximal possible pressure for a
duration of 30 minutes. After this time, it automatically returns to the original
settings. During the patient care function, the buttons for the pressure settings and
static settings are deactivated. When you need to leave the patient care setting
earlier, you can do this by pressing the reset function (press alarm button and cycle
button simultaneously) or the power button .
