Instructions for replacing the water filter
9.4.4 OPERATING TIME OF THE OSMOSIS FILTER
Over time, the osmosis membrane is blocked by small particles, impeding the passage of the pure water. For reasons of operational
safety and for hygienic reasons, the osmosis filters should therefore be replaced when its maximally recommended operating time is
reached, however, once every 2 years at the latest.
In the course of the osmosis filter replacement, the rotation lamellae and the humidifier tank should also be cleaned.
