Notes on further maintenance work
Note:
In accordance with national regulations, a pressure vessel inspection may be
prescribed to be carried out at regular intervals by an independent supervisory
offi ce.
For an inspection of the pressure vessel, the purifying- and drying agent must
be removed.
When inspecting the pressure vessel, it is recommended to check the conditi-
on of all fi ttings such as e.g. sieve bottom and dust sieve, including gaskets. If
necessary, these fi ttings must be cleaned or renewed.
In the event of comprehensive maintenance or repair tasks, contact the manu-
facturer.
Every 12 months
Replacing pilot valves
The pilot valves are part of every service kit and must be replaced every 12 months.
Renew purifying agent
Note:
To the layers of different purifying agent in chamber, you fi nd an overview of
technical data in annex.
The active surface of the purifying agent can be reduced by oil residue and other contami-
nants. The purifying agent must therefore be replaced once every 12 months (after approx.
8,500 operating hours). If the compressed air is insuffi ciently dried before it reaches the
adsorber (see technical data in the appendix), the service life of the purifying agent can be
considerably shortened. In this case, the agent must be replaced every 6 months (after ap-
prox. 4,000 operating hours).
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 signifi cantly from the degree of contamination in the
compressed air (or the quality of the compressed air upstream fi lters). Oil, dust, and dirt parti-
cles cover the drying agent surface and reduce its effective surface, in part quite irreversibly.
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 re-
placed every 24 months as a precautionary measure.
Replacing solenoid coils
Solenoid coils come with the 24-month service kits. Replace them every 2 years.
