Page 3: Introduction
DEAR CUSTOMER You have just become the owner of a direct heating electric boiler which was designed for central heating systems with a user friendly regulation option for thermal comfort. PROTHERM wants your electric boiler to serve you at a high level of efficiency. In order for it to do so, it is necessary to adhere to certain principles when installing and operating the boiler. -
Page 4: Boiler Characteristics And Equipment
2. BOILER CHARACTERISTIC AND EQUIPMENT 2.1. CHARACTERISTICS PROTHERM electric boilers are designed for usage in heating warm-water systems with forced water circulation. They serve as heaters of heating water, which is then pumped and distributed through central and level heating systems to heating bodies. -
Page 5: Control And Signalling
3. Control and signalling The electric boiler is designed for unmanned operation. After switching on of the main power supply switch there is a green signal light lit on the control panel (see the picture of the control panel) signalling, that the electric boiler is connected to the mains. -

water in the system. A pressure drop is also signalized by a yellow signal light. The type of failure can be identified according to the integrated pressure meter/thermometer reading. In order to achieve maximum operation efficiency (minimalized electricity costs) it is necessary to add an appropriate regulating mechanism to your heating system, which maintains the required temperature when you are at home and will lower the indoor temperature automatically at night or when nobody is at home. -

Page 10: Maintenance
8. Maintenance The electric boiler does not require maintenance. It is recommended, however, that a service company check the boiler once a year, preferably before the heating period (this is not included in the warranty). The skilled control should to tighten all the electric and water connections, to clear a pump, a safety and a deaeraling valve, to check safety components and in ending globally to attest a correct function of the boiler. -
