6.2. Optional accessories
Products may be equipped with optional accessories that are not
included with the basic product and must be ordered separately:
Filter regulator / set 604012967-000 /
The filter regulator filters out impurities in the compressed air down to a size
of 5 m. The use of this accessory on a compressor without a dryer partially
reduces moisture content in the supplied compressed air. Filtered
compressed air is suitable for use anywhere its parameters meet the
stipulated requirements. The regulator ensures a supply of output air at a
constant pressure (so long as the pressure value set on the regulator is not
higher than the switching pressure set on the pressure switch).
Regulator / set 604022073-000 /
The regulator ensures a supply of output air at a constant pressure (so long
as the pressure value set on the regulator is not higher than the switching
pressure set on the pressure switch).
Automatic condensate drain / set 604011998-000 /
The automatic condensate drain automatically drains condensate from the compressor's air tank based on a
pre-set time interval.
The drain automatically opens a solenoid valve at a pre-set time interval to drain condensate from the air
tank.
A timer is used to set the time between actuation of the solenoid valve (approximately 30 minutes).
The time between actuations of the solenoid valve can be adjusted to a lower value if excessive amount
of condensate is generated.
- The TEST button (2) is used to check the actuation of the solenoid valve, and when pushed the
solenoid valve should open (ON) and the time between actuations of the solenoid valve begins from this
point.
- The LED (1) lights up to signalize the valve is open(ON).

7. FUNCTION
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 (9).
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, dry and clean air is then ready for
additional use in the air tank.
Compressor with membrane dryer (MD) (Fig. 2)
The compressor (1) draws in air through an inlet filter (8) and compresses it through a check valve (3) into a
cooler (10). The air then passes through a filter (33) and micro-filter (34) into the dryer (35) with the dry and
clean air passing through a check valve (3) to the air tank (2). Condensate from the filter and micro-filter is
automatically released into a drainage vessel. The dryer ensures continuous drying of the compressed air.
Compressed, dry and clean air is then ready for additional use in the air tank.
Compressor with NDL dryer (Fig. 3)
The compressor (1) draws in air through an inlet filter (8) and compresses it through a check valve (3) into
the cooler (10). The air then proceeds through the condensate separator (15) and the drying chamber (11)
with the adsorbent media where moisture is removed and then on to the air tank (2). The adsorbent media
regenerates when the drying chamber is being evacuated, always after the compressor is switched off by the
pressure switch. The air is then released from the adsorption chamber via the open solenoid valve as it is
evacuated using dry compressed air. Air drying occurs in one chamber while regeneration occurs in the
other chamber. The mode of each chamber changes in regular cycles and the drying and regeneration
processes are then performed in the alternate chamber. Compressed, dry and clean air is then ready for
additional use. Constant output pressure is maintained by the pressure regulator (12).
The pressure switch (13) protects the dryer from damage if the compressor operates for an extended period
of time at low pressure (less than 5 bar)
Compressor cabinet (Fig. 4)
The soundproof cabinet itself is compact yet allows sufficient exchange of cooling air.
The fan (18) underneath the compressor aggregate and the cabinet fans (26) cool the compressor and the
space inside the cabinet. The fans operate when the compressor motor is running. The cooling fans
automatically start if the temperature in the cabinet reaches over 40°C, even when the compressor is not
running. The fans automatically switch off once the cabinet temperature drops to around 32°C.
An indicator (29) located on the front of the cabinet indicates maintenance is needed on the compressor with
the NDL dryer unit (see the Maintenance Interval chapter)
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.

12. FIRST OPERATION
(Fig.17)
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 cabinet-mounted compressors, turn the switch (28) in Fig. 4 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. As the air is used, the compressor works in automatic mode,
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 NDL - expanding regeneration air is vented out of the noise muffler on the dryer, which is audible as a
short hiss when the compressor stops or when the dryer chambers switch when the compressor is running.
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

13. SWITCHING THE COMPRESSOR ON
(Fig.17)
Switch on the compressor at the pressure switch (2) by turning the
knob (3) to position “I.” (for compressor in the box switch (28) Fig.4), on
the front part of the compressor box), 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 cutoff pressure the compressor turns off automatically and
the cycle is repeated. Check the value of switching-on and switchingoff pressure on pressure gauge. The values may be within a tolerance
of 10%. Air pressure in air chamber must not exceed maximal
permitted operation pressure..
Never tamper with the pressure switch (2). Adjustments are not allowed. The pressure
switch (2) has been set by the manufacturer and further setting of switching on and off
pressure may be carried out only by a qualified expert trained by the manufacturer.

Prior to any maintenance or repair work, switch off the compressor and disconnect it from
the mains (pull out the mains plug).
TO ENSURE THAT THE COMPRESSOR WORKS CORRECTLY, PERFORM THE FOLLOWING
MAINTENANCE TASKS AT REGULAR INTERVALS (CHAPTER 14).:
THE CABINET MUST BE OPENED ON CABINET-MOUNTED COMPRESSORSBEFORE
CONDUCTING THE FOLLOWING CHECKS.
15.1. Equipment cleaning
The equipment, in particular the cooling fan must be kept clean to ensure the long-term efficiency of the
cooler – the cooling fins must be cleaned occasionally to remove any dust.
15.2. Condensation drain valve
Compressors (Fig.18)
Switch off the compressor at the mains. Reduce air pressure in the
appliance to max. 1 bar by releasing air via a connected device.
Install the hose (062000492-000) provided with the standard product into
the valve (1) and drain condensate from the tank into the vessel by
opening the drain valve (1). Wait until all condensate is drained from the
pressure tank. Then close the drain valve (1), remove the hose by
compressing the plastic ring (2) and pulling it out of the valve.
Cabinet model compressors
Compressors with air dryer
In the case of a regular operation condensate is automatically excreted via air dryer and it is entrapped in a
bottle. Take out the bottle from a holder, release cap and pour out the condensate.
15.3. Check of dryer function
Check for proper dryer function by opening the vent valve. No condensate should leak out. Seek
professional assistance if condensate appears during such venting!
15.4. Safety valve check
(Fig.17)
When the compressor is operated for the first time, make sure that the safety valve is working properly. Turn
screw (4) of safety valve (1) several rotations to the left until the safety valve releases air. Let the safety
valve blow out for only a few seconds. Turn screw (4) to the right until it seats, closing the valve.
The safety valve must never be used for depressurizing the air tank. It could damage the
safety valve. The valve is set to the maximum permitted pressure by the manufacturer.
Adjustments are not permitted.
