Condition
1
Aftercooler (WSD in case of a water-
cooled compressor)
2 Air tube to OSCi vessel 2
3 Soleniod valve
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 acase-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.

Remedy
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 airtube 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.
