Procedure
1.
Close the manual condensate drain valve(s) if present.
2. Open the air outlet valve (AV).
3. Switch on the voltage.
4. Press the start button on the Elektronikon® controller.
5. The motor starts and stops automatically depending on the air pressure.
6. On compressors equipped with a refrigerant dryer, the dew point of the refrigerant dryer will be
reached after a few minutes.
7. On compressors equipped with an additional (membrane or desiccant) dryer, the latter will start
drying the compressed air. Note that at the first startup, it can take several minutes before its dew
point has stabilized to a final value.
6.3 During operation
Procedure
1. Check the Elektronikon® display to check pressure setting.
2. On compressors with a built-in refrigerant dryer, check the Elektronikon® display or the temperature
gauge (Gd) on the control pane to check the dew point.
Check that condensate is discharged regularly by the automatic drain of the dryer. The amount of
condensate depends on the operating conditions of the unit and the humidity of the air.
Open the manual drain valve from time to time to remove eventual impurities (see also section
Preventive Maintenance schedule).
3. On compressors equipped with the optional desiccant dryer (CD), regularly check the pressure
difference indicator of the PD 20
+
filter in front of the compressor. Replace the filter element if the
indicator shows red. Open the manual drain valve from time to time to remove eventual impurities
(see also section Preventive Maintenance schedule). Check the status of the LED's on the dryer
control panel at regular intervals.
If the Warning/Alarm LED is alight, consult the section Problem solving.
4. On receiver mounted compressors, open the manual drain valve of the air receiver regularly to
remove the water (specially in case of compressors without dryer). See also section Preventive
Maintenance schedule).
The dew point will deviate from nominal when the nominal conditions are exceeded. If
the dew point remains too high or unstable, consult section Problem solving.
