Removing the check valve plate
Before reassembling the check valve plate, you should replace the drying agent.
Replace drying agent
The service life of the drying agent is usually approx. 3 to 5 years. However, in
favourable installation conditions, the change of drying agent may be carried out
at a substantially later date (for notes on the installation site, see also page 20).
The change interval is determined by the degree of contamination of the
compressed air (which can be minimised by regularly replacing upstream filter
elements). Oil, dust, and dirt particles cover the drying agent surface and reduce
its effective surface, in part quite irreversibly. If in doubt, have a sample of your
drying agent assessed by specialists.
Comply with the following safety notes when changing the drying agent:
Wear eye protection and dust mask due to increased dust generation!
When emptying the drying agent, increased dust generation may occur.
In order to avoid any eye irritations, wear protective goggles!
In order to avoid any dust inhalation, wear dust mask!
