This series of sound emitters is very reliable and actually has just one moving part – the membrane. For sound emitters to always provide full effect, however, they must be regularly serviced.
Symptom:
The sound emitter produces audibly lower acoustic effect.
Corrective action:
The membrane may be worn. Remove the cover and check the membrane.
Picture of worn membrane
Om det finns en nersliten "grav" i membranet måste membranet bytas. Byt samtidigt även packningen. Om ljudsändaren inte går bättre trots byte av membran måste lockets och husets toleranser kontrolleras (rätt mått finns i instruktionsboken). Vid eventuella frågor, kontakta Kastrup & Genberg. Om delarna måste svarvas om går det bra att skicka dem till:

Symptom:
The sound emitter does not start.
Corrective action:
The sound emitter's membrane has cracked and must be replaced. Alternatively, the membrane in the solenoid valve may be damaged and require replacement.
Symptom:
A hissing sound is emitted from the air preparation devices filter section, alternatively, the filter section is full of liquid.
Corrective action:
The automatic drainage mechanism is not working and must be replaced. This drainage mechanism should be considered as a wear part and must be periodically replaced.
Note:
This sound emitter's membrane should be considered as a wear part and must be periodically replaced. Even if a sound emitter is functioning properly, preventive service should be performed once a year. Contact Kastrup & Genberg.
