Page 78: Operating Principle
Operating principle In the electrode boiler humidifier, the current flowing between the electrodes in the water in the cylinder generates the heat necessary to boil the water. By controlling the water level and the concentration of salt measured in the steam cylinder (U1) using the feed water solenoid valve (U8) and the boiler cylinder electric drainage valve (U9), the electric current is regulated by means of an amperometric transformer (U11). -
Page 79: Maintenance
Maintenance The only maintenance required is periodic inspection and cleaning of the steam boiler components. This should be carried out at least once a year, preferably before the summer holiday shutdown. BOILER CYLINDER Limescale deposits must be cleaned periodically from the electrodes and particles of limescale must be removed from the filter at the base of the cylinder. -
Page 80: Electric Heaters
Electric heaters Leonardo Evolution units can be equipped with electric heaters. For each model there are two levels available: standard and improved. The finned elements are characterised by maintaining low power density of the surfaces in a highly efficient way, therefore limiting overheating of the elements and consequently increasing their lifespan. -
Page 81: Temperature And Humidity Sensor
Replacing the electrical heaters WARNING! Before replacing the electrical heaters, disconnect the power supply from the unit. Make sure that it is not possible for the power to be turned on again while they are being replaced. WARNING! The heaters must only be replaced by a qualified electrician. The total power of the electrical heaters is divided into different elements, each of 3 kW. -
Page 82: Connection To Fresh Air Intake
Connection to fresh air intake The unit can be fitted with an optional fresh air filter. During installation, connect the intake of the fresh air filter to the nearest external air inlet with a flexible hose which has a diameter of 100mm and secure the hose to the fresh air intake with a fastening collar. The connection from the unit to the external air inlet must have the shortest and straightest path possible. -
