Maintenance

Oleophilic filter
Initially, the oleophilic filter (3 - Condensate flow scheme) 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. When the top of the filter reaches the surface of the
condensate in the first vessel, the filter is saturated and needs to be replaced. This is automatically
transmitted to the Elektronikon® regulator via the level sensor (1 - View of OSCi inlet), but the customer
can also check this visually through the sight-glass.
Quality check of the condensate
Every week, a test sample should be collected during compressor operation.
1. Open the condensate sample valve at the side of the compressor (drain plate) for 5 seconds and
dispose of the collected condensate according to local regulations for oil-containing water (this is the
water that remains in the test outlet tube between the OSCi and the compressor back panel).
2. Re-open the test valve and collect the condensate in the test bottle.
