condair Electrode Steam Humidifier EL20

The Nortec EL steam humidifier control software monitors the performance of the cylinder and indicates when a cylinder is full of scale and no longer able to achieve full output.

When the control software detects the cylinder can no longer achieve full output, the "Cylinder Spent" warning message appears on the Home screen. Replace the steam cylinder(s) – refer to "Removal and Installation of Steam Cylinder" on page 66.

Note: If the steam cylinder is not replaced, and the maintenance counter is not reset within 72 hours (run time), a corresponding fault message appears.;
