1.  If the automatic operation LED (8-Fig. 1.11) is alight, the regulator is automatically controlling the 

compressor modules (starting/stopping). 

2.  Check the readings on display (2-Fig. 1.11). In case of a warning or shut-down condition, see 

section 8.3. 

3.  Check that condensate is discharged automatically from outlet (2-Figs. 1.9) during running. 
 
Note: The dewpoint will deviate from nominal when the nominal conditions are exceeded.  If the 

dewpoint remains too high or unstable, consult section 6. 

 

1.  Check the starting and stopping pressures (1-Fig. 1.10). 
2.  Regularly open the drain valve underneath the air receiver for a few seconds, close the valve after 

draining. 

 

1.  Press stop button (9-Fig. 1.11). 
2.  Close air outlet valve (3-Figs. 1.5/1.6). 
3.  Switch off the voltage. 
4.  Open condensate drain valve (1-Fig. 1.9). 
 

1.  Move switch (2-Fig. 1.10) to OFF.   
2.  Close air outlet valve (2-Figs. 1.2/1.4). 
3.  Switch off the voltage. 
4.  Open the condensate drain valve underneath the air receiver (if provided) for a few seconds, close 

the valve after draining. 

 

 
1.  Stop the compressor and close the air outlet valve. 
2.  Switch off the voltage and disconnect the compressor from the mains. 
3.  Open the condensate drain valve.  Depressurize the compressor 
4.  Shut off and depressurize the part of the air net which is connected to the outlet valve.  Disconnect 

the compressor from the air net. 

5.  Disconnect the condensate piping from the local condensate drain system.
