  • Page 131 5. STARTING, CONTROL AND SHUTDOWN IMPORTANT WARNINGS: 1. Before starting the unit, check that the humidifier is in good condition, that there are no water leaks and that the electrical parts are dry. 2. Do not power the appliance if it is damaged or even partially wet! When installation is completed, flush the supply hose for around 30 minutes by piping the water directly into the drain without sending it into the humidifier.
  • Page 132 6. MAINTENANCE AND SPARE PARTS Replacing the cylinder IMPORTANT WARNING: the cylinder may be hot. Allow it to cool before touching it or use protective gloves. To access the cylinder: • completely drain the water contained in the cylinder; • turn the appliance off and open the mains power disconnecting switch (safety procedure); •...
  • Page 133 Maintenance of the other components in the water circuit IMPORTANT WARNINGS: • when cleaning the plastic components do not use detergents or solvents; • scale can removed using a solution of 20% acetic acid and then rinsing with water. The steam humidifier has just one part that requires periodical replacement: the steam production cylinder. This operation is necessary when the lime scale deposits that form inside the cylinder prevent the sufficient passage of current.

  • Page 138 7. OPERATING PRINCIPLE, CONTROL AND OTHER FUNCTIONS Operating principle In an electrode humidifier the production of humidity is obtained inside a cylinder (boiler) containing water that is heated to and then held at boiling temperature. The water that evaporates over time is automatically replaced with water from the mains supply. The heat required to boil the water is produced by passing an electrical current through the cylinder.
