Condition Fault Remedy
No enough air flow
during the test.
Disconnect the strainer (4-View of OSCi inlet) and take out
the strainer. Clean the strainer and the nozzle with
compressed air and dry tissue. Check that the air tube does
not touch any other components and is not hindered in any
way. Repeat the test procedure.
If the airflow coming out of the air tube is still not sufficient,
order a spare part solenoid valve (3-OSCi air injection).
In case there was enough airflow during the test, check to
see if there is a thick oily condensate present in all 3
vessels. Then check the oil separator element and the
scavenge line flow of the compressor and order the
corresponding service kits in case these components are
not working correctly.

cooled compressor)
4 Strainer

3 Solenoid valve 6 Air tube to EWD
Automatic as well as manual safety devices to prevent overflow are present. Besides the
automatic overflow switch (7-View of OSCi), which is mounted in a side-chamber on the second
vessel and gives an alarm when condensate level is too high, the customer can check for high
condensate level through the sight glass. On a case-by-case basis, it can be decided to
automatically shut down the compressor in case of an overflow alarm. When overflow occurs, the
resulting waste water must be treated as oil-containing water and must be disposed of according
to local regulations.
