Does a water separation system have to be installed between the water supply and the device?

The ear irrigation system may only be installed by a service technician authorized by ATMOS. Attention is thereby paid to compliance with national standards. In Europe, EN 1717 requires a suitable protective device to protect drinking water. ATMOS offers the water supply system ATMOS Aqua clean for this purpose.

Why does water run continuously through the ear irrigation system?

To heat the water for ear irrigation, a highly sensitive electronic control is necessary that requires a constant flow of water in the water heater. As long as the irrigation handle is removed from its support but not activated, the water in the hose returns to the device and is passed on to the wastewater. This is the only way to ensure the temperature stability that is important for the patient.
