WATER CHARACTERISTICS

The characteristics of the water used to fill the system are very important to prevent the build-up of mineral
salts and the formation of incrustations along the pipes, in the boiler and in the heat exchangers.
Therefore, please ASk YOUR PLUMBER FOR HIS ADVICE CONCERNING:
Hardness of water circulating in the system, to prevent problems of incrustation and
limescale, especially in the domestic water heat exchanger. (\x3e 25° French).
Installation of a water softener (if water hardness exceeds 25° French).
Filling the system with treated water (demineralised).
Possibly providing an anti-condensation circuit.
Installation of hydraulic shock absorbers to prevent water hammering along the fittings
and pipes.
If you have very extensive systems (with a large amount of water) or which require frequent refilling, the
installation of water softening systems.
It should be remembered that incrustations drastically reduce performance due to
their extremely low thermal conductivity.

GENERAL PRECAUTIONS

Electrical safety of the system is ensured only when it is properly connected to an efficient earthing system
made in compliance with the safety standards in force: gas, water or heating systems pipes are not suitable
as earth connections.
One must check this essential safety requirement; if in doubt, request an accurate inspection of the electrical
system to be carried out by qualified personnel, because the boiler manufacturer is not responsible for any
damage caused by failure to earth the system.
Have professionally qualified personnel check the electrical system is suitable for the maximum power
absorbed by the heating system, ensuring in particular that the diameter of cables is appropriate for the
power absorbed by the loads.
The use of any component that is powered by electricity entails compliance with some basic rules such as:
• do not touch the appliance with wet and/or damp body parts and/or bare feet;
• do not pull the electric cables;
• do not leave the appliance exposed to weathering (rain, sun, etc.);
• do not allow the appliance to be used by children or inexperienced persons.
230V electrical power supply connection
Installation of the boiler accessory electrical components requires electrical connection to a 230 V – 50 Hz
