10.2.1 Checking the seals of the ED12

The seals in the ED12 may age faster under aggressive ambient
conditions. Defective seals will lead to pneumatic leaks and non-
compliance with the IP 65 protection class.
Every now and then, check that the seals on the pressure
regulator are in perfect order.
A damaged seal can be recognized by parts of the seal visibly
protruding from the housing gaps.
