7. PRODUCT FUNCTIONALITY
Compressor (Fig. 1)
The compressor aggregate (1) draws in air through an inlet filter (8) and compresses it through a check
valve (3) into an air tank (2) from which the appliance draws compressed air. If the pressure in the air tank
drops to the switching pressure, the pressure switch (4) turns on the compressor and the compressor
supplies compressed air to the air tank until it reaches the switch off pressure, at which time the compressor
switches off. The pressure hose is vented through the relief solenoid valve (13) once the compressor unit is
shut off. The safety valve (5) prevents the pressure in the air tank from rising above the maximum allowed
value. The drain valve (7) drains condensate from the air tank. Compressed, oil-free filtered air is stored in
the air tank ready for use.
Condensate must be drained from the air tank at regular intervals (see Chapter 18).
Compressor with membrane dryer. (Fig. 3)
The compressor aggregate (1) draws in air through an inlet filter (8) and compresses it, feeding it to the
cooler (14) through the filter (15) to the dryer (9) and the dry, clean air is then fed through the check valve
(3) into the air tank (2). A portion of the air bypasses the dryer with the captured moisture, which is
manifested as a gentle stream of air along the body of the dryer (9). Condensate from the filter is
automatically drained at regular intervals into the vessel via the condensate drain solenoid valve (16). The
dryer ensures continuous drying of the compressed air. The drain valve (7) drains condensate from the air
tank when drying performance is checked. Compressed, oil-free filtered air is stored in the air tank ready for
use.
The compressor with dryer requires no operator. The pressure vessel does not need to be drained.
Compressor with condensate and filtration unit (Fig. 2)
The compressor aggregate (1) draws in air through an inlet filter (8) and compresses it through a check
valve (3) into an air tank (2). Compressed air from the air tank flows through a cooler (10) that cools the
compressed air. The condensed moisture is trapped in the filter (11) and automatically separates as
condensate (12) into the vessel. Compressed, oil-free filtered air is ready for use.
Condensate must be drained from the air tank at regular intervals (see Chapter 18).
Compressor enclosure
The soundproof enclosure is compact and allows sufficient cooling air exchange. The design makes it
suitable for in-office installations in a way that blends in with other furniture. The fan under the compressor
aggregate ensures sufficient cooling for the compressor and runs with the compressor motor or when the
temperature switch is activated at temperatures above 40 °C.
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.
The 10 bar compressor model is equipped with an hour meter (Fig. 4).

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
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 by the
attached appliance (see the Malfunctions chapter)
9. SWITCHING THE COMPRESSOR ON
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.
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!
The dryer will suffer damage if operated at ambient temperatures above the maximum
working temperature!
(Fig. 5)
Turn the compressor on at the pressure switch (2) by rotating the
main switch (3) to the “I” position. Check the position of the breaker
switch, it must be in the “I” position. If it is in the “0” position, turn
the switch to the “I” position (Fig.3 – position 18). The switch (Fig. 4
– position 22) in the case of DK50-10 S/M 10bar compressors is on
the front side of the enclosure; the indicator lights up green. The
compressor switches on and begins to fill the air tank until the
pressure reaches the switching pressure and the pressure switch
turns the compressor off. The compressor then operates in
automatic mode and is controlled by the on and off pressure
settings on the pressure switch based on compressed air usage.
This pressure may be monitored on the pressure gauge (5). A
tolerance of 10% is acceptable. The pressure in the air tank may
not exceed the permitted operating pressure.
Changing the switching pressures on the pressure
switch is prohibited on any compressor.
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.

15. COMMISSIONING
(Fig. 10)
Make sure all transport stabilizers were removed.
Check that all pressurized air line connections are secure.
Check to ensure power is connected correctly to the compressor.
Check the position of the main switch; it should be in the “I” position; if the switch remains in the “0”
position, turn the main switch to the “I” position. (Fig. 3)
Check to see if the DK50-10S/M enclosure (8-10 bar models only) is connected to the compressor using
the cable with the connector.
The compressor is not equipped with a backup power supply.
16. SWITCHING THE COMPRESSOR ON
(Fig. 10)
3
Turn the compressor on using the pressure switch (2) by rotating
the selector (3) to the “I” position. Check the position of the
breaker switch, it must be in the “I” position. If it is in the “0”
position, turn the switch to the “I” position (Fig.3 – position 18).
2
5
The switch (Fig. 4 – position 22) in the case of DK50-10S/M 10bar
compressors is on the front side of the enclosure; the indicator
lights up green. The compressor switches on and begins to fill the
air tank until the pressure reaches the switching pressure and the
pressure switch turns the compressor off. The compressor then
operates in automatic mode and is controlled by the on and off
pressure settings on the pressure switch based on compressed air
usage. This pressure may be monitored on the pressure gauge
(5). A tolerance of 10% is acceptable. The pressure in the air
tank may not exceed the permitted operating pressure.
Fig. 10
Adjustments to the pressure range on the compressor’s pressure switch are prohibited.
The pressure switch (2) was set up by the manufacturer and only a qualified technician
trained by the manufacturer may make any changes to its settings.
Compressor – when first started and placed into service, the compressor fills the air tank until the switching
pressure and the pressure switch turn off the compressor. The compressor operates in automatic mode,
switched on and off by the pressure switch, depending on compressed air usage.
Compressor with dryer – the compressor operates in the same manner as above, only the compressed air
passes through a cooler to remove moisture from the compressed air.
Compressor with a condensate and filtration unit (KJF-1) - during usage by the appliance, the
compressed air passes through the KJF-1 unit, where the air is cooled, filtered and condensed liquid is
captured and automatically drained into a vessel.
17. COMPRESSOR SHUT-DOWN
Compressor shut-down for service or any other reason is performed at the pressure switch (2) by turning the
selector (3) to the “0” position and pulling the mains plug from the socket. This disconnects the
compressor from power. Then open the drain valve (Fig. 1) to vent the pressure in the air tank to zero.

Check the ambient temperature – the ambient temperature must be below the temperature limit (40
°C). Cool the space if the temperature is high.
On the compressor with dryer – open the plug on the condensate vessel to drain the condensate
18.3. Leak check compressed air connections and inspect the equipment
Leak check:
Leak check the compressed air lines when the compressor is running and under pressure (not during
regeneration venting).
A Use a leak analyser or soapy water to check all joints and connections for leaks. Tighten or reseal
the connection where leaks are found.
Equipment inspection:
Check the condition of the compressor aggregate for normal operation and noise levels.
Fan operation check - the fans must be running during the defined compressor work cycles
Check of temperature switch operation (B2) – heat the temperature switch to a temperature above
40°C (e.g. using a heat gun, being careful not to warp any plastic pieces nearby). Fan EV1 (and EV2
for a compressor with dryer) will start up once the temperature reaches 40°C so long as power is
connected to the compressor.
Check filter condition – the filters must be undamaged and sufficiently clean.
Check the condition of the aggregate itself and ensure there is no contamination inside the crankcase
or play in the crankshaft
Replace any defective parts as needed.
18.4. Inspection of electrical connections

condensate drain on the air tank condensate drain to allow the
condensate to drain without operator intervention (see the
Scope of Delivery – Accessories chapter).
Compressors with air dryer (Fig.13)
Condensate from compressors with air dryers is automatically
drained into a vessel. The vessel must be drained regularly, see
Chapter 18.2
Fig.13
THE FOLLOWING IS REQUIRED BEFORE ANY FOLLOW-UP CHECKS:
For DK50-10S and DK50-10S/M compressors with an enclosure - remove / lift up the enclosure.
For the DK50-10S/M 10 bar compressor model with an enclosure - remove the cover of the
enclosure, disconnect the enclosure connector from the compressor connector and remove / lift up
the enclosure.
18.6. Safety valve check
(Fig. 14)
When the compressor is operated for the first time, make sure that
the safety valve is working properly. Turn the screw (2) on the
safety valve (1) several rotations to the left until the safety valve
releases air. Let the safety valve vent for only a few seconds. Turn
the screw (2) to the right until it seats, closing the valve.
Never use the safety valve to vent air pressure in
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!
