IMPORTANT INFORMATION
CONFORMITY WITH THE REQUIREMENTS OF EUROPEAN UNION DIRECTIVES
This product conforms to the requirements of the Medical Device Directive (93/42/EEC) and the
Machinery Directive (2006/42/EC), and is safe for the intended use if all safety instructions are
followed.
INTENDED USE
The compressor is used as a source of clean, oil-free compressed air to power dental unit,
instruments, and devices in laboratories where the parameters and properties of the compressed
air are suitable for the specific application.
Compressed air supplied by the compressor is unsuitable for use with artificial
lung ventilation devices without further filtration
Any other use of the product beyond its intended use is considered an incorrect use. The
manufacturer is not liable for any damages or injuries resulting from the incorrect use.
CONTRAINDICATIONS AND SIDE-EFFECTS
There are no contraindications or side-effects known.
WARNINGS AND SYMBOLS
The following symbols are used in the user manual, device and its packaging to denote important
details and information:

STORAGE AND TRANSPORT
The compressor is shipped from the factory in a transport packaging. This protects the device from
damage during transport.
The original compressor packaging must be used for transport whenever possible.
Transport the compressor in an upright position, always secured with transport
fixation.
Protect the compressor from moisture, dirt and extreme temperatures during transport
and storage. Store the compressor in its original packaging in a warm, dry, and dust-free
area. Do not store near any chemical substances.
Keep the packaging material, if possible. If not, please dispose of the packaging material
in an environmentally-friendly way. Packaging cardboard can be recycled with old paper.
The compressor may only be transported when all air pressure has been vented.
Before moving or transporting the compressor, release all air pressure from the
tank and hoses and drain condensate from the air tank.
Storing or shipping the equipment in any conditions other than those specified
below is prohibited.
Ambient conditions for storage and transport
Products may only be stored and transported in vehicles that are free of any traces of volatile
chemicals under the following conditions:
Temperature: –25°C to +55°C, 24 h at up to +70°C

aField strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the equipment is used exceeds the applicable RF compliance level above, the equipment should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the equipment.
bOver the frequency range 150 kHz to 80 kHz, field strengths should be less than 3 V/m.

8.2.4. Condensation and filtration unit (KJF)
The compressor may be additionally fitted with a condensation and filtration unit (KJF-1 or KJFR-1).
The KJF-1 or KJFR-1 ensure that the compressed air from the air tank is cooled in the cooler and
the condensate is captured in the filter and automatically separated from the pneumatic distribution
system. The compressed air is filtered at the same time.
PRODUCT FUNCTIONALITY
Compressor (Fig. 1)
The air pump (1) draws in atmospheric air through an inlet filter (8) and compresses it through a
non-return valve (3) into an air tank (2) from which the device draws compressed air. If the pressure
in the air tank drops to the switch-on pressure, the pressure switch (4) turns on the compressor and
the compressor supplies compressed air into the air tank until it reaches the switch-off pressure,
when the compressor switches off. The pressure hose is vented through the relief solenoid valve
(13) once the air pump is shut off. The safety valve (5) prevents the pressure in the air tank from
rising above the maximum allowed value. The drain valve (7) drains condensate from the air tank.
Compressed, oil-free filtered air is stored in the air tank ready for use.
Condensate must be drained from the air tank at regular intervals (see Chapter 19.1).
Compressor with membrane dryer (Fig. 2)
The air pump (1) draws in atmospheric air through an inlet filter (8) and compresses it, feeding it
through the coolers (14) and the filter (15) into the dryer (9) and the dry, clean air is then fed through
the non-return valve (3) into the air tank (2). A part of the air is released from the dryer with the
captured moisture, which is manifested as a light air stream along the body of the dryer (9).
Condensate from the filter is automatically drained at regular intervals into the collecting bottle via
the condensate drain solenoid valve (16). The dryer ensures continuous drying of the compressed

Compressed, oil-free filtered air is stored in the air tank ready for use.
The pressure vessel does not need to be drained.
Compressor cabinet
The soundproof cabinet provides compact covering of the compressor, allowing sufficient exchange
of cooling air. With its design It can be placed in a dentist’s office as a part of furniture. The fan
under the air pump of a compressor provides cooling of compressor and it is in operation at the
same time with an engine of the compressor. After prolonged use the temperature in the cabinet
may rise above 40°C, causing the cooling fan blower to automatically turn on. After cooling the
cabinet area down to 32°C the fan blower turns off automatically.
Make sure that nothing impedes the free flow of air under and around the
compressor. Never cover the hot air outlet on the top back side of the cabinet.
If placing the compressor on a soft floor such as carpet, create spacefor ventilation
between the base and floor or the cabinet and floor, e.g. underpin the footings with
hard pads.
The 8-10 bar compressor model is equipped with an hour counter (Fig. 3).

INSTALLATION
CONDITIONS FOR USE
Compressors may only be installed and operating in dry, well-ventilated and clean environments
with environmental parameters that meet the requirements specified in Chapter 7, Technical data.
The compressor must be installed so that it is accessible at all times for operating and
maintenance. Please ensure that the label on the device is readily accessible.
The compressor must stand on a flat, sufficiently stable base (be aware of the weight of the
compressor, see Chapter 7, Technical data).
Compressors may not be operated outdoors or in otherwise wet or damp environments. Do not
use the compressor in the presence of explosive gases, dust or flammable liquids.
Before connecting the compressor to medical equipment, the supplier must confirm that it meets
all requirements for its use. Refer to the technical data of the product for this purpose. When a
unit is to be built-in, classification and evaluation of compatibility must be done by the manufacturer
or supplier of the product to be used.
Any other use or use outside this framework is not considered as intended use. The manufacturer
is not responsible for any damages arising from such use. The operator/user assumes all risks.
Only a qualified professional may install the compressor and place it into operation
for the first time. This professional is obliged to train operating staff as to the use
and maintenance of the device. Installation and training of all operators shall be
confirmed by the installer’s signature on the certificate of installation.
Prior to installation, ensure that the compressor is free of all transport packaging
and stabilizers to avoid any risk of damage to the product.
Parts of the air pump may be hot and reach hazardous temperatures during
compressor operation and may pose a contact risk for operators or materials. Burn
or fire hazard! Caution! Hot surface!
Ambient operating conditions
Temperature: +5°C to +40°C,
Max. relative humidity: 70%,
Max. absolute humidity: 15 g/m3.
