Introduction
For your safety and the safety of your patients
These operating instructions are intended to explain how to use your product. However,
we must also warn of possible dangerous situations. Your safety, the safety of your team
and, of course, the safety of your patients are very important to us.
Please observe the safety instructions!
Intended purpose
This treatment unit is used for the diagnosis and therapy of children and adults in the field of dentistry.
Improper use can damage the treatment unit and thus pose risks and
hazards to the patient, user and third parties.
Qualification of the user
The DKL treatment unit may only be used after medically, professionally and practically trained
personnel have been instructed. The development and design of the treatment unit were geared
towards the target group of dentists, dental hygienists, qualified dental employees (prophylaxis) and
dental assistants.
Production according to EU directive
The medical device complies with the provisions of regulation (EU) 2017/745.
0123
Responsibility of the manufacturer
The manufacturer can only be held responsible for the impact on the safety,
reliability and performance of the treatment unit if the following instructions
are observed:
> The dental unit must be used in accordance with these operating
instructions.
> If assembly, additions, new settings, changes or repair work is carried out
by DKL or trained technicians authorised by DKL or personnel of authorized
dealers trained by DKL.
> The electrical installation of the room must comply with the regulations of
the IEC 60364-7-710 standard („Erection of electrical installations in rooms
used for medical purposes“) or comply with the regulations applicable in
your country.
> The recommended annual maintenance is carried out and any repair work
in this context meets the requirements of EN 62353.
> „Repeat tests and pre-commissioning tests of medical electrical equipment
and systems – general regulations“are fully complied with.
> The national legal regulations are observed when using the device, in
particular the applicable health and safety regulations and accident
prevention measures.

6
Electromagnetic Compatibility (EMC)
Medical electrical equipment is subject to special precautions with regard to EMC and
must be installed and commissioned in accordance with the EMC instructions. DKL
guarantees that the dental unit complies with the EMC guidelines only if original DKL
accessories and spare parts are used. The use of accessories and spare parts not
approved by DKL may lead to an increased emission of electromagnetic interference or
to a reduced resistance to electromagnetic interference.
The EMC manufacturer declaration can be found on page 42.
HF communication equipment
Do not use portable and mobile HF-communication equipment (such as mobile
telephones) during operation. These can affect medical electrical devices.
Risks due to electromagnetic fields
The functionality of implantable systems, such as cardiac pacemakers and
implantable cardioverter defibrillators (ICD), can be influenced by electric, magnetic and
electromagnetic fields.
> Before using the product, ask the patient and user about implanted systems and
check the use.
> Perform a risk-benefit analysis.
> Do not place the product near implanted systems.
> Do not place the instruments on the patient‘s body.
> Take appropriate emergency precautions and respond immediately to health changes.
> Symptoms such as increased heart rate, irregular pulse, and dizziness may be signs
of problems with a pacemaker or ICD.

7
Safety notes – General
> Before being put into initial operation, the treatment unit must be kept at room
temperature for 24 hours.
> Before each application, check the treatment unit and the instruments with cables for
damage and loose parts.
> Do not operate the treatment unit if it is damaged.
> Check the set parameters each time you restart the unit.
> Carry out a test run before each application.
> The application and timely shutdown of the system is the user’s responsibility.
> Make sure that in the event of a device or instrument failure, the treatment can be
completed safely.
> Use only original DKL fuses.
> Never touch the patient and the electrical connection at the treatment unit at the same
time.
> Do not lean on the the assistant‘s device, the tray or the operating lamp.
> When moving the treatment chair, the doctor‘s device, the assistant‘s device, the tray or
the operating lamp, pay attention to the patient and the practice personnel.
> Always switch off the treatment unit before leaving the practice.
Hygiene and care before using the device
> Clean and disinfect the device immediately before or after each treatment!
> Wear protective clothing.
The treatment unit is classified as an „ordinary device“ (closed device without protection
against water ingress).
The treatment unit is not suitable for use in an explosive atmosphere or in explosive
mixtures of anaesthetics with oxygen or nitrous oxide.
The treatment unit is not suitable for use in rooms with an oxygen enriched atmosphere.
Safety notes – Patient chair
> Not suitable for patients who cannot remain in a resting position due to mental or
physical disabilities.
> The patient‘s arms and legs must rest on the upholstered parts of the chair.
> Do not exceed the maximum patient weight of 150 kg.
> Do not sit on the head or foot rest of the horizontally aligned patient chair.
> Position changes must always be carried out under the surveillance of the person
giving treatment.
> Watch patients while moving the treatment chair.
> Make sure that there are no objects under the treatment chair.
Observe your country-specific guidelines, standards and specifications for
cleaning, disinfection and sterilisation.

8
> Before putting the device into initial operation and after downtimes (weekends,
(public) holidays etc.), flush the water lines intensively.
> Flush all instrument connections for 2 minutes before starting work.
> Press the glass fill button several times before starting work.
> Rinse used instruments for 20 seconds after each treatment.
Risk of injury or infection caused by instruments that are not in use:
The arrangement of the instruments may cause injury or infection to the hand and
forearm when accessing the tray or the display.
Therefore, when accessing the tray or the display, pay attention to the arrangement of
the instruments.
> Do not exceed the maximum permissible load of 2 kg on the assistant’s
device.
Highly immunosuppressed patients or patients with specific lung diseases should not
get into contact with the water of the treatment unit.
It is recommended to use sterile solutions.

Media Requirements
• Perform the installation according to the national installation requirements (e.g. EN 1717).
• For the reduction of microorganisms in the water supply pipe, please observe the following when laying this pipe to the
treatment unit:
- Avoid long stub lines to the treatment unit.
- Select the installation in such a way that other essential consumers (e.g. washbasin) are as far as possible
behind the connection of the treatment unit can be supplied from the same pipe.
- Avoid laying the hot water supply pipes in parallel.
• Recommendation: For the water supply of the treatment unit, install an angle valve with 2 outlets and 2 stop cocks. The
second outlet allows easy sampling of water for microbiological analysis.
Clean air and water pipes before installing the unit.
Chips and other foreign substances could be flushed or blown into the treatment unit.
Metal chips can interfere with the function of pneumatic components. Filters are clogged by foreign substances.
• When assembling, make sure that there are no chips or other foreign substances in the pipes.
• Flush the water pipes.
• Blow out the air ducts.
• Make sure that no further foreign substances get into the pipes and ducts after rinsing or blowing out.
Before the treatment unit is installed, the microbiologically perfect water quality of the domestic water supply
should be ensured and documented in the form of a microbial count.
Sampling and microbial count should be carried out by a competent laboratory.
Connection to the public drinking water supply
The treatment unit with a water separation unit complies with the requirements of EN 1717 (free outlet with separation
distance ≥ 20 mm) and the DVGW (German Technical and Scientific Association for Gas and Water). It is intrinsically safe
in accordance with worksheet W540 and therefore also meets the requirements of W270 and KTW (guideline for hygienic
assessment of organic materials in contact with drinking water).
When the treatment unit is equipped with a cuspidor, the bowl rinser ensures the free outlet with a separation distance
≥ 20 mm. When the treatment unit is equipped with a Bottle Care System, the spray supply of the instruments is separate
from the public water supply.
