by absorption and reflection from structures, objects and people.
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. PRODUCT DESCRIPTION
8.1. Prevedenia
Compressor models are designed in the following variants:
Dental compressor DK50
oil-free compressor embedded on a base covered with a compact
housing with an efficient noise suppression.
Upon customer request the compressor is provided with rubber feet or casters (2 with brakes (22) in
front and 2 without brakes (23) in the back).
Without additional filtration equipment, the compressed air from a compressor is
not suitable for the operation of breathing devices or similar equipment.
he compressor is not equipped with an emergency power supply.
9. FUNCTION
(Fig.1)
The compressor (1) draws in air through a filter and compresses it through a check valve (3) into
an air tank (2). The connected apparatus draws the compressed air from the air tank until the
pressure drops to a default preset level on the air-pressure switch (4) switching the compressor on.
The compressor again compresses air into the nozzle until the maximum pressure is reached and
the compressor switches off. Safety valve (5) prevents the pressure in air chamber from rising
above the maximal allowed value. The drain valve (8) releases the condensate from the air
nozzle.
The soundproof box is compact yet allows sufficient exchange of cooling air. Fan (6) provides for
the compressor cooling. After a prolonged operation of a compressor, temperature in the casing
can rise above 40°C, at that time the ventilator shall be in operation also after the compressor is
switched off after the space within the casing is cooled down under ca 32°C. Fastener (14)
ensures the power cord and its possible release from the connector (10).
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 space for
ventilation between the base and floor or the cabinet and floor, e.g. underpin the
footings with hard pads .

INSTALLATION
11. 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.
he 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.
Ambient operating conditions
Temperature: +5°C to +40°C,
Max. relative humidity: 70%,
Max. absolute humidity: 15 g/m3.
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!
Electric cord for connection to electric mains and air hoses may not be broken.
The power cord may not be exposed to pulling, pressure and excessive heat
