11�2 Choose operational mode
When 2 or more compressed air stations are connected
to the same network then one compressed air station
must run in main operating mode, all others must be set
to run in auxiliary operating mode� The factory setting is
for main operating mode�
In order to use more than one compressed air
station connected to a single display panel, all
the units must be connected to one network�
• Set the appropriate operational mode of the compressed
air station at the display panel�
11�3 Document acceptance test
• Check the compressed air station according to the
final testing/handover examination and record
• (See appropriate form in Appendix�)
11�4 Measuring dew point (optional)
Only carry out dew point measurements after approx� 4
complete fillings of the pressure tank (approximately 16
m
3
) have been used�
• The compressed air for the dew point measurement should
be taken from the measuring connection point (1)�

• If the refrigerant dryer does not automatically switch
on, use the operating panel and switch it on from
here�
Once the refrigerant dryer is switched on the
dew point temperature is shown�
After approximately 60 seconds the compressor aggre-
gate start up one after the other�
After two to 3 minutes the refrigerant dryer displays
a temperature between 32°F /0 °C and 39,2°F /+4 °C�
Once the cut off pressure has been reached the com-
pressor aggregates switch off one after the other�
• Check all compressed air connections and lines for
any signs of leakages�
• Open the shutoff valve to the compressed air network�
