Maintenance
Check the filters regularly as explained below in order to prevent untreated condensate from
entering the sewer.
Sample the condensate weekly.
•
If the filters are not installed properly, oil-containing condensate can leave the OSC.
•
When
new activated carbon filters are placed, the outgoing water may initially look black
(caused by carbon dust). This is not harmful.
•
Each new filter is provided with a label. The correct position is marked on the label.
•
Used filters can be heavy.
•
See to it that no condensate comes into contact with eyes, mouth, …
Checking the condensate
Every week, a test sample should be collected during compressor operation.
1.
Open the test valve and collect the condensate in the test bottle.
2. Compare the turbidity of the sample with the 15 ppm turbidity reference bottle.
Test/sample bottle (1) and turbidity reference bottle (2)
Oleophilic filter
If the activated carbon filter has to be replaced, do this first (see section Activated carbon
filters).
Initially, the oleophilic filter will float almost completely on the condensate and only the bottom part will act
as
filtration medium. By sorbing more and more oil, the filter will sink and new filter material will be exposed
to the condensate.
