1Preface and general instructions
The various bed systems from Hermann Bock meet special requirements for the use in
care and treatment facilities as well as for home care. Reliable functionality and a long
product life make each bed particularly valuable. Our beds need little maintenance with
proper operation and care. Each bed from Hermann Bock must pass quality testing in a
final inspection before it is shipped anywhere. The beds are manufactured according to
the current standards for medically used beds and tested accordingly.
The beds comply with the EN 60601-2-52 standard. The electrical building components
comply with safety standard EN 60601-1 for medical devices. Nursing care beds are med-
ical devices and are to be assigned to Class 1.
These standards divide the beds in five different areas of use:
1. Intensive care in a hospital; intensive care bed
2. Short-term care in a hospital or other medical facility
Furnishings, patient bed in hospital
3. Long-term care in medical environment; stationary nursing care bed
4. Care at home, pure so-called “HomeCare bed”
5. Home-care nursing service
1.1 Intended purpose
The nursing care bed is suitable for persons (adults) in need of
care who are at least 146 cm tall. The person's weight may not
exceed 155 kg and must be over 40 kg. The body mass index
(BMI = weight of the person (kg) / body height of the person (m)2)
must be greater than or equal to 17.
The nursing care bed may be used in homes for the elderly or nursing homes and rehabil-
itation facilities. It is used to alleviate a disability and/or to facilitate the lives of people
who are in need of care or to make the work of their caregivers easier. Furthermore, the
nursing care bed was also designed as a convenient solution for the home care of frail and
elderly people as well as for home care of people with disabilities. Accordingly, the nursing
care beds are designed to be used for the application areas 3 to 5. Any other use is con-
sidered improper and is excluded from a possible liability claim.
The Trendelenburg function may be used exclusively under supervision of medical profes-
sionals. The beds, which are determined for environment type 4, are equipped with a
hand control which is unable to operate the Trendelenburg function.

5
The nursing care bed is not suitable for use in hospitals. It is also not designed to transport
patients. The beds can only be moved within the patient's room - even during patient
positioning - for cleaning or better access to the patient, for example.
The bed is suitable for the re-use. Please observe the instructions for cleaning, care and
disinfection in these assembly and operation manual. Special attention must also be paid
to the information regarding the inspections.
A special transport and storage system has been developed for the transport of this nurs-
ing care bed, which is also described in this assembly and operation manual.
Attention: The beds come with no special connection options for a potential equalisation.
Electrical medical devices connected to the patient intravascular or intracardiac may not
be used. The operator of the medical products has to ensure that the combination of the
equipment meets the requirements of EN 60601-1:2006.
This user manual contains safety instructions. All persons working with the beds must
be acquainted with the contents of these instructions. Improper operation can result in
personal injuries.
1.2 Definition of person groups
Operator
Operators (e.g. medical supply stores, specialist dealers, facilities and cost units) include
all physical or juridical persons, who use the beds or have the beds used for medical pur-
poses. The briefing on the use of the product shall generally be conducted by the operator.
User
Users are persons whose training, experience or briefing on the product allows them to
operate the nursing care bed or carry out works on it. The user is able to recognize possible
hazards and/or to avoid them and to assess the health condition of the patient.
Patient/resident
Person with one or more disabilities, one or more activity restrictions, one or more par-
ticipation restrictions or a combination thereof.
Qualified personnel
Employees of the operator are referred to as qualified personnel. They are entitled to
deliver the nursing care bed, assemble, dismantle and transport it, on the basis of their
training or instructions. Besides knowing how to operate, mount and demount the nursing
care bed, these persons must be instructed according to the guidelines concerning the
cleaning and disinfection of the nursing care bed.

1.3 Safety instructions
The intended use/operation of all moving parts is as important for the safety of the person
in need of care as well as for the relatives and the caregivers/nursing staff to avoid poten-
tially dangerous situations. This requires the correct installation and operation of the bed.
The individual physique of the person in need of care as well as type and the extent of
their disability must be taken into account by all means when operating the bed.
Avoid dangers, accidental motor adjustments and incorrect operation by using the disa-
bling function. When the operator, e.g. the caregivers or the care providing relative leaves
the room, the entire operating functions of the bed should be disabled via the hand con-
trol. This is achieved by operating the key of the hand control. First, lower the lying surface
to the lowest position and activate the lock function with a twist of the key (located in the
key lock on the backside). Remove the key and check the function of the hand control for
safety reasons. Make sure that it is indeed locked.
These recommendations apply particularly:
-if the person in need of care cannot operate the hand control safely due to cer-
tain disabilities;
-if the person in need of care or the caregivers could be at risk due to those acci-
dental adjustments;
-if the side rails are in a raised position and there could be danger of trapping and
crushing,
-if children are unsupervised in the room with the bed.
Always make sure that the hand control (when not in use) is securely hooked in the sup-
port hook at the bed and cannot drop.
As a general rule, the bed should be operated by instructed nursing staff/caregivers, rela-
tives or in attendance of instructed persons.
When adjusting the lying surface, it is particularly important to ensure that no limbs are
placed within the adjustment range of the side rails. If the side rails are adjusted, pay
attention to the correct lying position of the person in need of care.
Prior to making any electrical adjustment, it should, as a general rule, be made sure that
no limbs are positioned in the adjustment range between the chassis and the head or foot
part, especially that there are no persons/animals in the area between the floor and the
raised lying surface. Danger of being crushed is particularly high in these areas.
The permitted person’s weight depends on the total weight of the equipment that has
been mounted to the bed (mattresses and other electronic medical devices). For safe
working load, please refer to the type plate on the lying surface frame of the bed.

1.4 Service life / warranty
This nursing care bed was developed, designed and manufactured for safe operation over
a long period of time. With proper operation and maintenance,
this nursing care bed has an expected service life of 7 to 10 years. The service life depends
on operating conditions and frequency.
Attention: Unauthorised technical changes to the product voids all warranty claims.
This product is not approved for the North American market, particularly not for the
United States of America (USA). Distribution and use of the nursing care bed in these
markets, including through third parties, is prohibited by the manufacturer.
1.5 Requirements for the installation location
The company Hermann Bock GmbH is not liable for damages which might arise from the
daily usage on the floor.
To avoid floor indentations, floor should correspond to the recommendations of the FEB
- Fachverband der Hersteller elastischer Bodenbeläge e. V. (Association of Elastic Floor
Coverings Manufacturers). To do this, the technical information FEB No. 3 can be refer-
enced.
Hazard note by Bock
Simultaneous use of electrical appliances particularly in the vicinity of the operational bed may
result in small electromagnetic interactions of these electric devices, e.g. static noise in the ra-
dio. In such rare events, increase the distance of the devices. Do not use the same socket or
temporarily switch off the interference source and/or the disturbing or disturbed device.
If the bed should be operated with electrical medical equipment (contrary to its intended use),
the functions of the bed must first be disabled via the integrated locking function in the hand
control for the duration of the application.

2General description of the functions
Construction design and function
Corrosion protection
The Hermann Bock GmbH nursing care beds are developed and constructed in such a way
that they can function long and safely. For this reason, all materials that may corrode are
protected accordingly. All metal parts are equipped with a surface protection. The steel
parts are either galvanised or stove-enamelled with a PES powder coating and the alumin-
ium profiles are anodised.
The lying surface with 4 function areas
The lying surface consists as standard of a slatted comfort frame (can alternatively be fit-
ted with aluminium slats or special suspension systems) and is divided into four functional
areas: Backrest, solid seat, upper and lower leg rest.
The comprehensive lying surface frame is welded from a steel tube. The steel tubes are
stove-enamelled with a PES-powder coating. The electric variable height adjustment of
the lying surface is carried out with protective low-voltage DC motors (29 to 35V), and
controlled with the smooth keys of the hand controller. The backrest can be adjusted elec-
trically. The leg part consists of a foot support that is divided into two parts. With a touch
of a button on the hand control, each individual position can be adjusted continuously. In
case of power failure, the back and/or leg part can manually be lowered through discon-
necting the motor mountings (locking pin).

11
The chassis
The height adjustment of the bed takes place through two height-adjustable manual con-
trols. The surface of the tubular steel structure is stove-enamelled with a PES-powder
coating.
The side rail
Each nursing care bed can be equipped on both sides with two side rails at a special safety
height. The side rails can be lifted and lowered through a rail. The sliding pieces run par-
ticularly smoothly and quietly with an impact damper, and each end is fitted with a func-
tional cap. The side rail can be easily operated through an ergonomically designed release
button.
The operation of the continuous side rail
The release button for the adjustment of the continuous side guard rail is located on the
upper side rail beam in the guide rail (Fig. 1).
If the side rails are to be lowered, grasp the provided gripping groove of the upper side
guard rail, lift the side rail slightly and press the release button on one side of the head
or foot part (Fig. 2). The side rail opens at the corresponding place and can be easily low-
ered downwards as far as it will go. The side rail is now diagonal. To lower the other side
as well, carry out the previously described steps on the opposite end. The side rail is now
in the lowered position.
Fig. 1 Fig. 2
Please observe:
Be sure to raise the side rail slightly, and only then press the release but-
ton! Failure to do so will result in damage to the release.
If the side rails are to be brought into the upper position as protection against falling out,
grasp the upper side guard rail in the middle of the gripping groove and pull the side rail
upwards until it audibly engages at both ends. The side rail is now in a pulled-up position.

12
The side rails first and foremost serve as a fall prevention. In the case of very emaciated
persons in need of care, this protection is no longer sufficiently provided by the side rails
and additional protective measures must be taken, e.g. by adding a sliding side rail pad-
ding (accessory). The distances of the continuous side rails must be less than 12 cm. When
using the continuous side rails, they may not remain in a diagonal position.

Hazard note by Bock
Use only original Bock side rails, which are available as accessories for every nursing care beds.
Use only technically flawless and non-damaged side rails with the permissible gap dimensions.
Make sure that the side rails are engaged securely.
Before installation of the side rail and each new use, inspect all mechanical parts on the bed
frame, and all parts of the side rails, and all parts which secure the side rails, for any possible
damages.
The operation of the side rail should be done with great care. Fingers can be quickly pinched
between the longitudinal pieces.

3Electric parts
3.1 The drive unit
The drive unit consists of individual drives for the electrical adjustment of the back and
leg rest part. The level adjustment is divided via two individual drives, which are attached
to the manual controls elements. The motors and the hand control are connected to the
inner control box. In the plug-in power supply, the input voltage is converted into a pro-
tective low voltage of maximum 35 VDC direct current. The motors and the hand control
function with this non-hazardous low protective voltage. The cables are double-insulated
and the mains plug has a primary fuse.
Internal emergency lowering is carried out by loosening the locking pin on the motor
mountings. Furthermore, power adjustment allows for constant speed of the functions.
Therefore, the safety functions comply with protection class II and the moisture barrier
protection type IPX4.
The maximum duty cycle is specified on the (type plate) of the bed. For example, 10% duty
cycle (2 min. ON / 18 min. OFF) means that any electronic adjustment can be performed
for a max. of 2 minutes within a timeframe of 20 minutes (protection against overheating).
If the maximum setting time of two minutes is exceeded by two minutes (e.g. someone
plays continuously with the hand control), which could lead to overheating of the drives,
the thermal fuse immediately shuts off the power supply to the bed. After a cooling down
time of approx. one hour, the power will be automatically supplied again.
3.2 Caution: Electric drive
The electrically operated nursing care bed enables the person in need of care to support
the recovery process psychologically and physically and at the same time relieve pain
through its various functions. Electrically operated beds that are medical products need
special care in regards to constant safety checks. This includes safety-conscious handling
of the bed, daily inspection of electrical equipment and proper maintenance and clean-
ing.
To prevent damages to the cables, wiring should be conducted outside of the area in
which damages could be caused. Furthermore, avoid touching the sharp parts. To prevent
injury through an electric shock, avoid the possibilities of too high contact voltages. These
circumstances may especially be the case if the power cable is damaged, if inadmissible
and excessive leakage currents exist, or if liquid was spilled into the motor housing, e.g.
during improper cleaning. This damage can cause malfunction of the control, which could
result in unwanted movements of single bed elements, posing a risk of injury for the op-
erator and the person in need of care.

16
3.3 Drives
Hermann Bock GmbH equips nursing care beds with drive systems from DewertOkin
GmbH.
Each drive consists always of four main components.
–Housing
–Motor
–Gear
- Spindle with nut
The housing principle of the individual drive guarantees the permanent function of all
drive components. Through a detailed interior structure, the construction of the housing
interior creates an essential prerequisite for the precise integration of the drive technol-
ogy, as well as a trouble-free assembly/disassembly.
3.4 The external switch mode power supply SMPS
The plug-in part of the external switch mode power supply (SMPS) is an electronic trans-
former, which warms up only to a minimum degree under load and it is equipped with
electronic performance monitoring. The result is a constant voltage up to the maximum
load (no loss of speed) and a high level of protection against overloading. The external
transformer ensures safety right from the socket because it converts the voltage directly
into the 29V safety low-voltage which is used to actuate the bed. It is connected via plug
coupling to the mains supply line feeder cable and can be replaced separately if defective.
The plug-in part of the external switch mode power supply complies with the European
directives for electrical household appliances. In standby mode, it also has a low energy
consumption of maximum 0.5 Watt and can be used internationally with variable input
voltages from 100 V to 240 V. Electromagnetic alternating fields are not measureable on
the SMPS adapter.

3.5 The control
The domiflex 2 / domiflex 2 wash is
equipped with a controller from
DewertOkin GmbH. Four drives can
be connected to the controller
(sockets 2,3,4 and 5), socket 1 is
used to connect the hand control.
Further information on colour cod-
ing can be found in chapter 4 "As-
sembly and operation".
Hazard note by Bock
All drive components must not be opened!
Troubleshooting or exchanging single electrical components may be performed only by special
qualified and authorized personnel.
Hazard note by Bock
The motors meet the water protection standard IPX4. Do not squeeze/crush the cables. Adjust-
ment of moving parts may only be used for the intended use. Hermann Bock GmbH assumes no
liability for unauthorized technical changes.
.
Hazard note by Bock
Do not try to fix failures on the electrical equipment itself. It could be fatal! Either call the cus-
tomer service of Hermann Bock GmbH or an authorised/licensed electrician who conducts the
troubleshooting in compliance with all relevant VDE regulations and safety regulations.

18
3.6 The hand control
The hand control is equipped with a built-in locking device, which allows the caregivers to
lock the hand switch via a key completely or partially for its operation.
The lockable hand control, first-fault protected
The basic functions can be controlled via the hand control at the touch of a finger on the
eight (standard hand control) or ten (hand control with special functions) operating keys.
The individual keys are marked with corresponding symbols. The servomotors run until as
long as a corresponding key is pressed and held. A coiled cable allows the necessary free-
dom of movement while operating.
With the rear-mounted suspension unit, the hand control can be attached to the side rail
- particularly when cleaning and during the maintenance of the bed. Thus, a possible dis-
ruptive position of the hand control can be avoided by simply attaching it to any preferred
spot on the bed.
