● Do not commission the device until it has been mounted completely and connected in accordance with the information
in Chapter "Technical data (Page 27)".
● Before commissioning take the effect on other devices in the system into account.

areas.
WARNING
Water in compressed air line
Device damage and possibly loss of type of protection. The factory setting for the purging air selector is "IN". In the "IN"
position, water from the compressed air line may enter the device from the pneumatics during initial commissioning.

If you cannot be sure that there is no water in the compressed air line:
● Set the purging air selector to "OUT". In this way, you prevent water from the compressed air line from penetrating the
device.
● Only set the purging air selector to "IN" again when all water has been discharged from the compressed air line.
