When do I have to clean the macro filter?


The macro filter should be cleaned each time you replace the dual filter (WP3990).

Cleaning instructions:

  1. Switch off the pure water dispenser.
  2. Turn off the water supply to the pure water dispenser.
  3. Unscrew the water inlet connector (hold it in vertical position to avoid water spillage) and pull out the macro filter.
  4. Rinse the macro filter under a running tap. Remove the dirt from the mesh.
  5. Put the macro filter back in its original position.
  6. Reattach the water inlet connector
