7. PRODUCT FUNCTION
7.1. Compressor
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 (13). Safety valve (5) prevents the pressure in air chamber from
rising above the maximal allowed value. The time of work of a compressor is recorded on an
operation clock. 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.
7.2. Compressor cabinet
The soundproof box is compact yet allows sufficient exchange of cooling air. It can be placed in a
dentist’s office. The ventilator 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 prolonged use the
temperature in the case may rise above 40°C, causing the cooling fan blower to automatically turn
on. After cooling the case area to 32°C the fan blower turns off automatically.
PRODUCT DESCRIPTION
06/2023 11 NP-DK50 B-A-2_06-2023
Risk of compressor overheating.
Make sure that there are no obstacles at the cooling air inlet into the cabinet
(around the bottom part of the cabinet) and at the hot air outlet on the top back
side of the cabinet.
If the compressor is placed on a soft floor, e.g. carpet, create space between the
base and the floor or the cabinet and the floor, e.g. underlay the footings with
hard pads to ensure sufficient cooling of the compressor.

during compressor operation that may harm materials or operating staff.
You may notice a “new product” odour when you first place the product into
service (for a short period of time). This odour is temporary and does not impede
the normal use of the product. Ensure the space is properly ventilated after
installation.
The compressor must be installed so that it is accessible at all times for operating and
maintenance. Please ensure that the nameplate 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 the Technical Data chapter).
Before connecting the compressor to 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.

OPERATION
ONLY TRAINED PERSONNEL MAY OPERATE THE EQUIPMENT!
Risk of electric shock.
In case of emergency, disconnect the compressor from the mains (pull out the
mains plug).
Burn or fire hazard.
Portions of the air pump may be hot and reach hazardous temperatures during
compressor operation that may harm materials or operating staff.
Warning compressor is controlled automatically.
Automatic start-up. When pressure in the pressure tank drops to switch-on
pressure, the compressor automatically switches on. The compressor
automatically switches off, when pressure in the air tank reaches the switch-off
pressure.
Potential for damage to pneumatic components.
The working pressure settings for the pressure switch set by the manufacturer
cannot be changed. Compressor operation at a working pressure below the
switching pressure indicates high air usage (see the Troubleshooting chapter).
During prolonged operation of the compressor, the ambient temperature around
the compressor may increase to over 40 °C. At this point the cooling fan
automatically switches on. The fan switches off once the space is cooled to
around 32 °C.
OPERATION
NP-DK50 B-A-2_06-2023 18 06/2023
14. SWITCHING ON THE COMPRESSOR
Fig. 5: Switching the compressor
Switch on the compressor at the pressure switch (1) by turning the knob (2) to position “I.” The
compressor sends pressurized air to the air tank. As the compressed air is used, the pressure in
the air nozzle drops to a preset level, the compressor switches on and the air nozzle files with
compressed air. After reaching the cut-off pressure the compressor turns off automatically and the
cycle is repeated. Check the value of switching-on and switching-off pressure on pressure gauge
(3). The values may be within a tolerance of 10%. Air pressure in air chamber must not exceed
maximal permitted operation pressure.
Risk of damage to pneumatic parts.
The pressure switch (1) was set up by the manufacturer and any other changes
to it settings may be performed only by a qualified technician trained by the
manufacturer.
15. SWITCHING OFF THE COMPRESSOR
Switching off the compressor due to service or any other reason shall be performed using the
pressure switch (1) by turning the switch (2) to position „0“ and pulling out the mains plug from
the socket. This disconnects the compressor from the mains supply.(Fig. 5)
Vent the pressure in the air tank to zero by opening the drain valve.

PRODUCT MAINTENANCE
16. PRODUCT MAINTENANCE
The operator should carry out device checks regularly in the intervals defined by
applicable regulations. Test results must be recorded.
The equipment has been designed and manufactured to keep maintenance to a minimum. The
following work must be performed to preserve the proper and reliable operation of the compressor.
Unauthorised interference hazard.
Repair work outside the framework of standard maintenance (see Chapter 16.1)
may only be performed by a qualified technician (an organisation authorized by
the manufacturer) or the manufacturer’s customer service.
Standard maintenance work (see Chapter 16.1) may only be performed by the
operator’s trained personnel.
Only use manufacturer-approved replacement parts and accessories.
Danger of injury or equipment damage.
Prior to commencing compressor maintenance, it is necessary to:
- check if it is possible to disconnect the compressor from the appliance in
order to avoid any risk of injury to the person using the appliance or other
material damage;
- turn off the compressor;
- disconnect it from the mains (pulling the cord out of the mains socket);
- vent the compressed air from the air tank.
Venting compressed air poses an injury hazard.
Wear eye protection, i.e. goggles, when venting compressed air from the
compressed air circuit (air tank) and from the dryer chamber.
Burn hazard.
Pump components (head, cylinder, pressure hose) have high temperature during
and shortly after compressor operation do not touch these components!
Let the device cool before any product maintenance, service or connection/
disconnection of pressurized air!
