Notes on further maintenance work
Every 12 months
Replacing pilot valves
The pilot valves are part of every service kit and must be replaced every 12
months.
Every 24 months
Replacing inlet valves (V1/V2) and check valves (V5/V6)
The inlet valves (main valves) and the check valves are part of the 24-month
service kits. Replace them every 2 years as a precautionary measure.
Expansion valves (V3/V4)
In addition to the inlet valves and the check valves, the expansion valves have to
be replaced every 24 months as a precautionary measure.
Replacing solenoid coils
Solenoid coils come with the 24-month service kits. Replace them every 2 years.
Every 48 months
In accordance with national regulations, a pressure vessel inspection may be
prescribed to be carried out at regular intervals by an independent supervisory
office.
For an inspection of the pressure vessels, the drying agent must be removed.
When inspecting the pressure vessels, it is recommended to check the condition
of all fittings such as e.g. sieve bottoms and dust sieves, including gaskets. If
necessary, these fittings must be cleaned or renewed.
In the event of comprehensive maintenance or repair tasks, contact the
manufacturer.
Renew 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. The change interval depends very significantly from
the degree of contamination in the compressed air (or the quality of the
compressed air upstream filters). Oil, dust, and dirt particles cover the drying
agent surface and reduce its effective surface, in part quite irreversibly.
