11. FIRST OPERATION
(Fig.8)

Make sure that all stabilizers used during transport were removed.

Check that all pressurized air line connections are secure.

Connect to the mains.

Start compressor at pressure switch (2) by turning switch (3) to position “I.“

For kompressor DK50 PLUS S turn the switch (28) (Fig.4) at the front part of the soundproof box to the
position “I“ – green light indicates that the appliance is on.
Compressor - At first operation the air tank is pressurized until it reaches a preset level when the
compressor automatically switches off. As the air is used, the compressor works in automatic mode,
switched on or off by the pressure switch.
Compressor with dryer - during operation the accessory dryer removes moisture from the compressed air
passing through it.
Compressor with condensation and filtration unit - Model KJF-1 filters and dehumidifies the air and
automatically releases condensed liquid through the filter´s discharge valve.
The compressor is not equipped with an emergency power supply.
OPERATION
In case of emergency, disconnect the compressor from the mains (pull out the mains
plug).
The compressor has hot surfaces.
Burns or fire may result if contact is made.
During prolonged operation of the compressor, the temperature in the box may increase to
over 40°C. At this point the cooling fan automatically switches on. After cooling the
space to under 32°C, the ventilator switches off.
Automatic start: when pressure in the tank drops to the pressure switch’s lower limit level,
the compressor automatically switches on. The compressor automatically switches off
after reaching the pressure switch’s upper limit level.
Compressor with dryer
A correct function of the drier depends on the compressor’s operation and no attendance is required. The
pressure vessel need not be sludged, because the pressure air entering the air chamber is already dried.

It is forbidden to alter the working pressures of pressure switch set by manufacturer. The operation of the
compressor at working pressure lower than the switching pressure demonstrates the overload of the
compressor (high air consumption) by the appliance, leakages in pneumatic distributions, failure of
aggregate or drier.

Prior connecting drier to air chamber, that was used with compressor without drier, it is necessary to clean
interior surface of air chamber and perfectly remove condensed liquid. Then interconnect electric part of
drier with compressor according to wiring diagram in accord with valid regional regulations.
Required drying performance can only be achieved when following the defined operating
conditions!
Drying performance will decline and the achieved dew point will drop if the dryer is
operated at any pressure below the minimum working pressure!
Dryer operation at a pressure of 0.5 Bar below the minimum working pressure can lower
the dew point at the outlet by more than 10°C!
The dryer will be irrevocably damaged and need replacement if operated at any
temperature above the maximum working temperature!
