1. Open the test valve and collect the condensate in the test capsule stored in the
compartment on the cover.
2. Compare the turbidity of the sample with the 10 ppm reference side on the test capsule.
Oleophilic filter
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
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.
Replacement instructions
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
), 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.
4. Remove the diffuser and pull out the mufflers. See section
.
5. Fit the new mufflers and diffuser.
6. Go to section
Filter replacement instructions
7. Fit the new filter (white label), observing the position.
Do not push the filter below the
water surface.
8. Fit the cover on the housing.
On QOCS 5300:
Repeat the instructions once for the left side of the unit and once for the right
side of the unit.
Filter
Replacement instructions
1. Open the test valve and empty the cartridge into a bucket. Drained condensate can be
poured back into the housing later.
2. Remove the screws of the cartridge and pull it away from the housing. It is not required to lift
the cartridge of QOCS 1325 – QOCS 5300 as they are provided with wheels.
3. Remove the ball valve at test outlet and place it to the new cartridge.
4. Remove the plugs from the new cartridge and place them to used one. This would make the
used cartridge leak tight.
5. Place the cartridge near housing close to housing almost at installation location but enough
gap to fill the new cartridge with clean water. Start filling the cartridge till the water starts
flowing out of the condensate outlet.
6. Push the cartridge into the housing and secure it with screws.
7. Pour back the drained condensate in the first step into the housing.
8. Fill the housing with clean water till water starts flowing out of condensate outlet.
9. Inspect for leaks at the connection between housing and cartridge.
