  • Page 52: 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 53: Maintenance

    Maintenance the only maintenance required is periodic inspection and cleaning of the steam boiler components. this should be carried out at least every six months, 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 54: Electric Heaters

    Electric heaters Jupiter units can be equipped with electric heaters. For each model there are two levels available: standard and improved. The fi nned elements are characterised by maintaining low power density of the surfaces in a highly effi cient way, therefore limiting overheating of the elements and consequently increasing their lifespan.

  • Page 55: 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 capacity of the electrical heaters is subdivided into more elements, each with a capacity equal to 2 or 3 kW based on the size of the unit.

  • Page 56: Connection To Fresh Air Intake

    Connection to fresh air intake The unit can be made ready for the intake of fresh air through an optional filter. The optional module for the fresh air intake, containing the filter cartridge, must be applied on the left side of the unit during the installation phase and correspond to the holes which introduce the air into the fan compartment.

  • Page 57: Discharge Temperature Threshold Sensor (Only On Chilled Water Models)

    Discharge temperature threshold sensor (only on CHILLED WATER models) An ntC temperature sensor is an optional accessory which maintains the supply air temperature of the unit above a threshold value. the sensor is connected to the microprocessor control system as described in the electrical diagram of the unit.
