HOW TO REPLACE THE CARTRIDGES
1. Close the water supply tap.
2. Close the tank tap by turning it 90 degrees.
3. Release the system pressure by opening the clean water tap.
4. Use a special key (included in the package) to unscrew the first filter housing.
5. Remove the used cartridge.
6. Thoroughly clean the inner surface of the housing using a brush.
7. Install a new cartridge. Be sure to remove the packaging from the new cartridge! Make sure that the O-ring is in its place, and tighten the housing clockwise.
8. Replace the remaining filter elements in the same way.
9. To replace the membrane, follow these steps:
- Disconnect the post-filter from the membrane housing.
- Disconnect the water inlet tube from the membrane housing. To do this, remove the locking clip and disconnect the tube by tightening the ring.
- Unscrew the membrane housing cover.
- Remove the packaging from the membrane.
- Install the membrane in the housing.
- Screw the membrane housing cover on
- Install the post-filter on the fixing clips.
- Insert the water supply tube and the locking clip into the membrane housing cover.
10. Before starting the system after changing the filter elements, it is necessary to rinse the pre-treatment cartridges. To do this, disconnect the water supply tube to the membrane and direct it into any container. After the water with coal dust stops flowing from the tube, turn off the water supply to the system and connect the tube to the membrane housing. This is necessary to extend the life of the membrane.
11. Open the water supply tap and the clean water tap. Allow the water to drain for at least 10 minutes. Close the clean water tap. Open the storage tank tap. Check the tightness of the connections.
