to the medical supply store, for example).
Care staff/Users
Care staff/users are skilled persons who, based on their training, experience or briefing,
are qualified to operate the care bed on their own authority or to carry out work with the
care bed, or have been instructed how to handle the care bed. Furthermore, they are
able to recognise and avoid potential hazards and assess the clinical condition of the
resident.
Residents
In this instruction manual, the term resident is defined as a person who is infirm or in
need of care and occupies this care bed.
When the bed is used in a private, domestic setting, it is strongly recommended that the
operator or his representative instruct each resident on how to use the bed functions
that are important for him/her.

operation of this bed.
•If any additional devices (such as compressors for positioning systems) are attached,
ensure that these are securely fastened and are working properly. Pay particular
attention to:
oSafe routing of all loose connector cables, tubing etc.
oEnsuring that no multiple socket outlets are located under the bed (fire hazard due
to ingressing liquids).
oChapter 2.3.2 of this instruction manual

Instruction Manual for Lenus Care Bed
Page 11
2.2.3 Safety information for users and residents
•Ensure that the operator/your medical supply store instructs you in the safe
operation of this bed.
•Ask a healthcare professional for advice if you are uncertain about a possible
application of safety sides or about the necessity of activating the locking functions
of the electrical adjustments.
•Check each time before using the bed to ensure that it is in perfect working order
(see also chapter 3.10.1). Ensure that no obstacles, such as bedside cabinets,
supply rails or chairs could impede adjustments to the bed.
•If any additional devices (such as compressors for positioning systems) are
attached, ensure that these are securely fastened and are working properly. Pay
particular attention to:
-Safe routing of all loose connector cables, tubing etc.
-Do not use multiple socket outlets placed loosely on the floor. These could
cause electrical hazards due to damaged mains cables or the ingress of liquids.
If anything is unclear, please contact the manufacturer of the device.
•If any damage or malfunction is suspected, take the bed out of service:
-Unplug the power adapter from the mains socket immediately.
-Indicate clearly that the bed is “OUT OF ORDER”.
-Report this immediately to the operator responsible/your responsible medical
supply store (see the address on the back cover of this manual).
•Route the cable of the power adapter, and also all other cables, in
such a way that they cannot be pulled, driven over or damaged by
moving parts when the bed is operated.
•Never leave unsupervised toddlers or babies alone with the bed!
oThere is a strangulation hazard due to the possibility of
entanglement in exposed connecting cables (such as the
power cable and handset cable).
oThere is a risk of suffocation from swallowing small parts
which may have become detached from the bed.
•Lock the electrical adjustment functions of the bed if their
unsupervised use could put staff or other persons at risk.
•The power adapter cable is fitted with a mains cable holder.
-Before moving the bed, always make sure that you have
unplugged the power adapter from the mains socket. Hang it
on the bars of the safety side with the mains cable holder to
ensure the power adapter will not fall off and the cable does not
trail on the floor.
•Do not place multiple socket outlets under the bed. This could cause
electrical hazards due to damaged mains cables or the ingress of
fluids.

Instruction Manual for Lenus Care Bed
Page 12
•Adjust the mattress base to its lowest position before leaving the
resident unattended. In this way, you considerably reduce the risk of
injury to the resident due to a fall when getting in or out of bed.
•Always ensure that the castor brakes are applied when the bed is
not being moved.
•When not in use, stow the handset in such a way that it cannot
inadvertently fall off (hang it up by the hook). Make sure that the
cable cannot be damaged by moving parts of the bed.
•Adjustments must only be performed by, or in the presence of, a
trained person.
•Before carrying out any adjustments, make sure that there are no
people, limbs, pets or objects in the way, in order to avoid
entrapment hazards and/or damage to property. This applies
particularly when mattress base sections are adjusted to a lower
height.
•To safeguard against unintentional motorised adjustments, lock the
relevant functions of the handset if:
-the resident is unable to operate the bed safely or to free
himself/herself from potentially dangerous situations.
-the resident could be at risk due to unintentional motorised
adjustments.
-The safety sides are raised (danger that the person's limbs could be
trapped when adjusting the backrest and thigh rest).
-children are left unsupervised in the room with the bed.
•Always ensure that the bed is in its lowest position before leaving
the resident unattended in bed. In this way you can minimise the risk
of injury should the patient fall out of bed.
•At regular intervals, carry out a visual inspection of the power
adapter and cable to check for mechanical damage (scuffing, cracks
in the housing, exposed wires, kinks, indentations etc.). Perform
such a check:
-Whenever the cable has been subjected to any mechanical load,
e.g. has been driven over by the bed itself or by an equipment
trolley.
-Whenever the cable has been bent, stretched or violently pulled,
e.g. due to the bed rolling away while it is still plugged into the
switch-mode power supply.
-Whenever the bed has been moved or relocated and before
plugging the power adapter back into the mains socket.
-Regularly, but at least once a week, by the user when the bed is
in constant use.
•Check the strain relief of the power adapter cable regularly to ensure
that it is securely fixed.
Observe the safety information found in this instruction manual!

Page 16
2.3.8 Special mechanical features (optional equipment)
–Removable comfort mattress base comprises 50 individual spring elements. These
elements are designed to mould themselves closely to the shape of the body and help to
ventilate the mattress. Their flexibility also ensures that the pressure is optimally distributed.
The comfort mattress base also significantly contributes to preventing pressure ulcers.
Bed extension, integral, extends the bed by approx. 20 cm. In this case, longer safety side
bars and side panels and a support base will be needed for the bed.If required, please
consult our sales department (see chapter 6.4)
2.3.9 Materials used
For the most part, the bed is manufactured from steel profiles whose surfaces are finished with
a polyester powder coating or a metal coating of zinc or chrome.
The head and footboards and safety sides are made of wood or wood-based material with
sealed surfaces. All surfaces that can be touched during normal use have been tested for bio-
compatibility and are harmless to humans when in contact with the skin.
2.3.10 Structural design
Mattress base
The mattress base is divided into a backrest, a fixed seat section, a thigh rest and a lower leg
rest. The rests are adjustable. The mattress base can be raised and lowered horizontally or set
to the reverse-Trendelenburg position with the foot end lowered (optional Trendelenburg

Remove the safety side bars and the patient lifting pole from the storage aid and
set them aside for the time being.
Remove the two halves of the mattress base frame from the storage aid.
Carefully place the head-end half and the foot-end half of the mattress base
frame onto the floor. The four mattress retainer bars should face upwards, while
the two drives face downwards.
Then fit the two halves of the mattress base frame together.
Set the long side of the mattress base frame on the floor and rest the frame
against the wall.
Remove the four long screws from the storage aid and use them to fix the two
halves of the mattress base frame together (in the middle).
Now carefully lay the assembled mattress base frame flat on the floor.

3.5 ASSEMBLING THE CHASSIS
Danger due to Trendelenburg position
Failure to comply could result in serious injury to the person lying in bed.
The two chassis [1] and [9] should not be confused! A mix-up will lead to an
unwanted Trendelenburg position instead of a reverse-Trendelenburg
position.
•Take care not to confuse the two chassis when assembling the bed.
•Observe the different labels for identification of the two chassis. These
are located centrally on the cross tubes, near the holder for the drive
motor and centrally on the cross tubes of the mattress base frame.
Adhesive label on the head section chassis
Adhesive label on the foot section chassis
Proceed as follows to attach the two chassis to the mattress base frame:
Remove both chassis from the storage aid
−To do so, pull the chassis out of the storage aid.
Connect the head section chassis [9] to the mattress base frame [17]. Make sure
that the adhesive labels match!
−To do this, lift the mattress base frame at the head end and slide the two
connection pieces of the head section chassis into the tubes of the mattress base
frame as far as they will go.
−Pull the head section chassis back out by approximately 10 mm until the holes
are aligned one above the other.
Fix the mattress base frame to the head section chassis with 2 long screws (M6x60,
supplied with the bed).
Repeat steps 2 and 3 with the foot section chassis [1].
Check to ensure that the two chassis are securely fixed to the mattress base frame.
Remove the plastic screws that secure the two chassis (see 1).
−Use a 5 mm Allen key to remove them.
−Save the plastic screws in case they are needed at a later date.
Use the supplied plugs to seal the holes in the chassis (see 2).
Note: The plugs can be found in the bag with the instruction manual.
