Compare the turbidity of the sample with the 10 ppm reference side on the test capsule

Sign off on the condensate check

Initially, the oleophilic filter will float almost completely on the condensate and only the bottom part will act as filtration medium. By absorbing more and more oil, the filter will sink and new filter material will be exposed to the condensate.

The filter must be replaced when the service indicator (see section Introduction) approaches the lid of the housing or when the condensate from the test outlet is less transparent than in the reference test capsule.

The lifetime of the filter depends on the amount of oil in the condensate.

Both filters should be replaced while servicing the unit. Filters should be replaced at least once per year irrespective of the loading.

1. Stop the compressor and close the air outlet valve. Switch off the voltage. Depressurize the outlet piping by opening the manual condensate drain.

2. Remove the lid of the housing and take out the oleophilic filter.

3. Only if necessary (see Problem solving, item 1), clean the inside of the condensate treatment device with water and tissue.

Do not use any form of soap or detergents as they could contain dispersants which deteriorate the ability to break oil/water emulsions.

Open the test valve and empty the cartridge into a bucket

Remove the screws of the cartridge and pull it away from the housing

Remove the ball valve at test outlet and place it to the new cartridge

Remove the plugs from the new cartridge and place them to used one

Place the cartridge near housing and start filling the cartridge with clean water

Push the cartridge into the housing and secure it with screws

Pour back the drained condensate into the housing

Fill the housing with clean water till water starts flowing out of condensate outlet

Inspect for leaks at the connection between housing and cartridge
