6. PRODUCT DESCRIPTION
6.1. Model variations and their uses
Compressors are the source of clean, oil-free compressed air used to drive dental appliances and
equipment.
Compressors models are designed for the following uses:
Dental compressors DK50
2V/50 - are designed for independent placement of the compressor in any
area.
Dental compressors DK50 2V/50/M - are designed for independent placement of the compressor in any
area and feature a membrane dryer.
Dental compressors DK50 2V/50S - feature soundproof boxes suitable for placing in the dentist‘s
surgery.
Dental compressors DK50 2V/50S/M - feature soundproof boxes and a membrane dryer.
DK50 2V/50 SKRINKA
Withou
t additional filtration equipment, the compressed air from a compressor is not suitable
for the operation of breathing appliances or similar equipment.
7. FUNCTIO
N
Compressor (Fig.1)
The compressor (1) draws in air through a filter (8) 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.
After compressor aggregate is switched off, pressure hose shall be pressure-release solenoid valve (10).
Safety valve (5) prevents the pressure in air chamber from rising above the maximal allowed value. The
drain valve (7) releases the condensate from the air nozzle. Compressed, clean air free from oil traces is
stored in the air tank ready for use.
Compressor with membrane dryer (Fig.3)
The compressor unit (1) pulls in outside air through the inlet filter (8) and compresses it through the cooler
(11), filter (13) and micro-filter (12) to the dryer (9) and on through the check valve (3) as dry clean air in the
air tank (2). Condensate from the filter and micro-filter is automatically drained into the collection vessel. The
dryer provides continuous drying of the compressed air. Dry, clean compressed air free from oil traces is
stored in the air tank ready for use.
Compressor box (Fig.4)
The soundproof box is compact yet allows sufficient exchange of cooling air. It can be placed in a dentist’s
office. The ventilator (14) under the aggregate of a compressor provides cooling of compressor and it is in
operation at the same time with an engine of the compressor. After a prolonged operation of the compressor,
when temperature in a casing rises above 40°C, the cooling ventilator of the casing (22) shall be switched
on automatically. After the area in housing is cooled down under ca 32°C, the ventilators shall be
automatically switched off.
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 case.
If placing the compressor on a soft floor such as carpet, create space for ventilation
between the base and floor or the box and floor, e.g. underpin the footings with hard pads.

INSTALLATION
8. USE
The appliance must be installed and operated in a dry, well ventilated and dust-free area where ambient
temperature is within the range of +5°C to +40°C and relative air humidity does not exceed 70%. Otherwise,
failure-free operation of the compressor cannot be guaranteed. The compressor must be installed so that it
is accessible at all times for operation and maintenance. Please ensure that the appliance label is
accessible.
The appliance must stand on a flat, sufficiently stable base. See paragraph 5 (Technical data) when
positioning or lifting the compressor.
Compressors cannot be exposed to outdoor environments. The appliance cannot be used in moist or wet
environments. Do not use the compressor in the presence of explosive gases, dust or combustible 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 use other than that described in this manual is not covered by the guarantee, and the manufacturer is
not liable for any damages that may result. The operator/user assumes all risk.

9. INSTALLATION
Only qualified personnel can install and start up the appliance and train operating
personnel in its correct use and maintenance. 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.
Caution! When in operation, the compressor is hot. Burns or fire may result if contact is
made by the operator or any flammable material.
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.
9.1. Placement of the compressor
Dental compressor DK50 2V/50, DK50 2V/50/M
(Fig.4)
After removing all packaging material, place the product on the floor and remove stabilization parts Y (Detail
A). Connect output hose with end-piece to the appliance. Plug the mains cord plug into a socket.
Dental compressor in box DK50 2V/50S (Fig.3, Fig.4)
After unpacking, place the product onto the floor in a room, release it from packaging materials and remove
fixation parts (Y) - detail A. Place a wall end stop (21) 2 pcs on compressor casing in the rear, upper part of
the casing and fit in the casing on the required place.The end-stops shall ensure the sufficient distance of the
casing from the wall for thorough ventilation. For fitting the compressor in the place to the casing it is
necessary to disassemble the casing door and take off the connecting reinforcement (28) in the front bottom
part of the casing. Protrude the pressure hose under the casing and fix it to the appliance in a suitable
manner. Grasp the compressor at its handle and using the transport mechanism (20) and the built-in
castors (15) place it to the casing. Embed the hose (27) of manometer (25) of the casing to fast-on coupling
on the compressor, place back the connecting reinforcement (28) and connect output pressure hose to the
compressor.
Connect the connector (26) of casing to the compressor and connect the electric mains plug to mains socket.

Fig.5)
Dental compressor in DK50 2V/50S/M, (Fig.3, Fig.4)
After removing all packaging material, place the product on the floor and remove stabilization parts Y (Detail
A). Place the compressor into housing similarly as in the previous paragraph. Prior to placing the
compressor into housing, protrude house for condensate drain via hole in housing and connect it to a bottle
(18). Magnetic holder (19) with a vessel (18), for entrapping the condensate from the dryer may be fitted
onto any vertical part of casing, or from front on its door. When fixing the holder with a vessel at the housing
side it is necessary to consider a space of at least 11 cm between the housing and furniture. Distance
smaller than the specified one may cause problem with handling of the vessel.
9.2. Compressed air outlet
(Fig.6)
Lead the pressure hose from the output of compressed air (1) to the
appliance – dental set.
9.3. Electrical connection
Plug the electrical cord into the mains.
The appliance is equipped with a grounded plug. Make sure this connection complies
with local electrical codes. The mains voltage and frequency must comply with the data
stated on the appliance label.
(Fig.7)
Keep the socket easily accessible to ensure that in an emergency the
appliance can be safely disconnected from the mains.
Connection to the power distribution box must be max.16 A.
The connection of the earth ground pin 6mm (1) with other
appliances must be completed in accordance with local electrical
codes. The female socket (2), which is not included in the standard
set, is an optional accessory.
Electrical cable may not contact the hot parts of a compressor. Insulation could be
damaged!
If any electrical cord or air hose is damaged it must be replaced immediately.
