SILEX return system
When the conductivity meter indicates that the quality of the SILEX produced water is too low, it is time to replace the cartridge.
If the inlet water is tap water quality, you can use the return system to replace the cartridge. Ship the depleted cartridge to your EUROWATER office and we will return a regenerated cartridge back to you.
Follow the instructions for a smooth and quick replacement.
Step-by-step guide
How to replace the SILEX cartridge
1. Close valves
Shut the valves on the inlet (a) and outlet (b). Slowly release the pressure with the air screw (c).
2. Open the lid
Unscrew the hand screws and remove the lid. Hold on to the o-ring.
3. Remove exhausted cartridge
Lift the used cartridge out of the SILEX-unit.
4. Drain the cartridge
Hang it to let it drip-dry for 60 minutes.
5. Empty the SILEX-unit
Dismount the SILEX-unit and tip it to drain the remaining water completely. For SILEX 2BS, use the outlet drain valve.
6. Load new cartridge
Carefully lower the cartridge into the unit using the plastic bag as a funnel.
7. Smoothing the cartridge
Carefully tug at the top of the cartridge to stretch it a bit.
8. Get the cartridge to settle
If possible, tap the unit to make the cartridge settle completely. Remount the vessel.
9. Be sure of good water quality
Tugging and tapping ensures a snug fit for the cartridge - essential for successful operation.
10. Add water and release air
Open the inlet valve until the vessel is filled. Let all air expel from the cartridge. It may take up to 10 minutes.
11. Close the lid
Make sure that gasket, O-ring and bearing surfaces are completely clean, then remount the lid and tighten the hand screws.
12. Open valves
Open the air screw (c), open the inlet valve (a). Close the air screw when it expels water. Open the outlet valve (b).
