FIRST OPERATION

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."(Fig.10)
 For cabinet-mounted compressors, turn the switch (37) in Fig. 5 on the front side of the equipment cabinet
into the "I" position; a lighted switch indicates the equipment is in operation.
 Compressor - At first operation the air tank is pressurized until it reaches a preset level when the
compressor automatically switches off.
switched on or off by the pressure switch.
 Compressor with dryer – Compressor operation is the same and the moisture from the compressed air is
removed as it passes through the dryer.
For M2 and NDL - the condensate is also blown out of the drain on the dryer, which can be heard as a brief
whoosh sound when the compressor shuts down or when the drying chambers switch.
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.
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
