CAUTION:
The system operating pressure must always be above the expansion tank preload:
2 bar for the expansion tank 1,5 bar.
CAUTION:
The Thermocell must also be connected only to 220V - 50Hz power supply"; the adjustments of Sensor S1 and Sensor S2
must be controlled by the heater / boiler and not by the Thermocell electric panel.
For this purpose connect 2 thermocouples (optional code no. 60010695) to the cable clamps of Sensor 1 and Sensor 2" of
the generator.
CAUTION:
Sensor S1 must be set at 65°C (over 65°C it switches off the boiler ). Sensor S2 must be set at 40 - 45°C (under 40 - 45°C it
switches on the boiler ).

Caution: it is mandatory to earth the heater / boiler. If this instruction is not observed serious damage, which is not
covered by warranty, will result to the body of the heater / boiler. Have an electrician check the earthing. There
must be no electric potential (volts) between the earth of the generator and the actual earth of the plant. To prevent
electrochemical corrosion of the boiler body do not use galvanised pipes and fittings. Dedicated ground wires must
be used to ground all other materials .
