1.1 General
Please read these operating instructions carefully in order to prevent damage during assembling and
before placing the health care bed with slatted frame into operation
Only accessories from Fa. Müller Kranken- und Pflegeeinrichtungen Werner Mühle GmbHwhich were
delivered with the bed (accessory kit) or were ordered as special equipment are to be used. The list for
special equipment is in 5.0
The user has to assure oneself of the good order and condition of the health care bed. On long-term
application (every 12 months) or reuse after storage it is necessary to check its functions and look for
visible damages.
The health care beds are produced following DIN EN 1970 – 2000 (standard for health care beds)
as well as
DIN EN 60601-2-38 (= standard for nursing beds / in dependence on)
The drive units comply with the EN 60601-1 specification.
Certain constellations, like positioning the bed next to other electrical equipment – like radio or
television - may lead to electro-magnetic interferences. In this case remove the devices or change the
position of the bed.
Storage condition:
The health care bed should always be used under the following conditions:
Storage temperature: + 10° to max. + 40 ° C
Relative air humidity : 30 to 75%
Air pressure : 700 – 1000 Hektopascal
When your bed has the special feature „Trendelenburg-position“it is possible to move the bed
with the charged accumulator battery only (without any further external power supply)
This shall secure the prone positioning in case of power blackout while Trendelenburg position.
If the bed is to bed stored for a longer period, a patient is transported in the bed or the power
supply is cut for security reasons it is absolutely necessary to unplug the connection from the
accumulator battery to the laying surface motor in order to prevent any unwanted displacing of
the health care bed. (see photo)
1. Remove the cap with a standard Phillips head screw driver
2. Here the accumulator battery is connected!
3. Unplug the plug and disconnect the accumulator power supply!
Finally you have to screw the cap back on the multiway connector!

1.5 Purpose / Range of use
The health car bed „Medial“ is especially designed for the home care area. The health care bed shall
facilitate the care of indigent or older people at home. It is not designed to be connected with other
medical electric devices. The health care bed is not fitted to be employed in hospitals or other fields of
medical care.
The safe workload is 1700 N (~ 170 kg) which include mattress (20 kg) as well as accessories
(15 kg). This leads to a maximum permitted weight of the patient of 135 kg.
The health care bed is not suitable for patients who measure less than 150 cm or more than 190 cm
(based on a lying surface length of 200 cm).
It is furthermore necessary to indicate the possible risk of crushing for emaciated patients since in this
case the standard security distance won’t be sufficient. For security reasons we advise you to put a
side-rail protection or protective cushions/ hose in use. This can be ordered via our service hotline or at
the specialised rehabilitation supply dealers.
Before operating make sure that the side-rails are in perfect condition and fully functioning
(see also 2.4).

The use of the side-rails is limited to securing members not to fall off laterally. To access and get out of
the bed it is absolutely necessary to put the wooden side-rails in its lowest position
There are no electro medical appliances in our beds permitted!
1.6 Basic materials in use
Several components of the health care bed are partly made of permanently powder- coated steel. The
derived timber products all have a high-quality surface-coating. All side rails are made of sheathed solid
plywood (spruce fir).
The solid wood is coated with an environment- and skin-friendly varnish. The sprung slats are made of
special surface-sealed plywood
1.7 Maintenance and recommended cleaning products
In order to ensure the economic life-time of your health care bed we strongly recommend as follows:
•Clean all metallic and wooden parts with a damp cloth only
•The same applies for the electrical engine; this one must not be cleaned with a high-pressure
cleaner.
•Due to hygienic reasons we recommend not to use any lubricants for the moveable parts.
•Do not use any tools like palette-knifes, knifes or similar.
•Do not use coarse-grained scouring agent
Please only use by the Robert Koch institute certified and approved disinfecting agents (Sagrotan) for
disinfecting the health care bed.
These are to be applied with a spray bottle and/or a cloth (made of cotton or microfiber) on the inlay
frame in order to clean and disinfect it. Apply the disinfecting agent through wiping with the cloth. We
strongly recommend removing the disinfecting agent after its residence time in order to avoid any
possible skin irritation. Always wear rubber gloves when disinfecting or cleaning the health care
bed!

1.8 Design and construction
It is possible to dismantle your health care bed into several portable parts which makes it easier to be
transported.
The health care bed can be completely assembled with the included tools (Allen key).
The lying surface is equipped with an electronically adjustable slatted frame. The backrest and the
knee-kink are individually adjustable and permit a comfortable position for the patient and the nursing
person respectively
A level adjustment (height adjustment) is possible via the head and food section (front) of the bed. It is
possible to choose between a parallel adjustment and a tangential deviation on the handset.
These parts of the bed are produced with welded steel tubing which has a varnish-annealed surface.
1.9 Mattress
Please use a special health care mattress RG 35 in accordance with DIN EN 597 of low flammability
with the following measurements:
Height: 120mm
Length: 2000 mm
Width: 900 mm
The measurements of length and width change accordingly to any changes of the lying surface,
i.e. 90 x 210 cm
This means that the mattress has got a length of 2100 mm.
It is recommended to install the heightened side-rails from our accessories-catalogue if other kinds of
back supports are used.
2.0 Assembly instructions
2.1 Assembling the health care bed
1. Operate the step-levers of the two front-modules as described in 4.4 and place them flat
against the wall – the square iron bars showing to the room-centre.
2. Both parts of the lying surface have to be stuck together at the butt joints and then tightened
manually with the enclosed winged screws (2 parts). The butt joints of the lying surfaces-halves
are the ones without a cross-iron bar at the outer frame
Grub Screws
(Enclosed in the accessories kit)
Winged bolt
3. We recommend placing both halves of the lying surface side-by-side on the floor and fitting the
parts in this position together. In addition to the winged

5. Repeat this procedure for the other front-module (Raise the lying surface and insert it on the
rectangular tubes, etc.) and make sure to get a securely attached connection of the front
module and lying surface.
6. Finally the 4 location points to the front modules behind the winged bolts have to be screwed
tight with one grub screw each (Allen key of the accessories kit).
2.4 Installation of the side-rails
1. There are 2 side-rails on each bedside needed.
Caution: Rounding points upwards!
2. First of all it is necessary to attach the 2 guide pushers to the front section ( push the
lower snap fastener and insert the guide pusher head-up through the lower opening
of the aluminium-rail; the guide pusher has to slide easily back and forth the two
snap fasteners).

3.5 Dismantling
Warning: When shutting down the bed (without mattress) it is
possible that the hoisted leg rest won’t be lowered down –
even when the motor is moving to its back position since
the unlade leg rest is too light. The leg rest can fall down at
any indefinite point in time.
Note: The health care bed should only be shut down when the lying surface is
at a levelled position.
For dismantling the health care bed please follow the instructions in reverse order – that means from
3.3 to 2.1!
3.6 Emergency lowering device
The health care bed disposes of mechanical equipment for a so-called emergency handling.
With this device it is secured that in case of a power blackout the front end of the health care
bed can be lowered down manually.
For executing the emergency lowering device it is necessary to operate the red emergency lowering
device-lever at the lying surface engine (see illustration below).
Should the bed dispose of the special feature „Trendelenburg positioning” it is possible to lower the
headrest via the emergency lowering device lever, and additionally, the emergency lowering of the
bed height and inclined position through an integrated rechargeable battery pack in the engine.
For this it is highly recommended to take notice of the following points:
If the health care bed is stored away for a longer period, an in-patient is transported or the
electric power supply is cut off for other reasons it is imperative to unplug the plug and socket
connection from the rechargeable battery pack to the lying surface engine ( refer to pages 4+5!)
so that no unintentional kinetic moving of the health care bed is possible.
-Before the initial operation the rechargeable battery pack has to be charged for at least
10 hours (through Power plug – socket connection) so that the full operability of the
emergency lowering device is guaranteed.
-The state of charge of the rechargeable batty pack can be seen at the pilot-light on the
manual control switch ( refer to illustration below)
