12. FIRST OPERATION
(Fig.98)
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 in the box turn the switch (24) (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
- In addition, adsorption dryer takes out humidity from the previous compressed air
during operation in the device and it blows out the entrapped condensate via condensate outlet on the dryer,
which is audible as a short hiss when compressor stops, or during the operation while switching the dryer
chambers.
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
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.
13. SWITCHING THE COMPRESSOR ON
(Fig.9)
Switch on the compressor at the pressure switch (2) by turning the knob
(3) to position “I.”, (for compressor in the box switch (24) 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 switching-off 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.
