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. (> 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.
EXAMPLE INSTALLATION DIAGRAMS
The following diagrams are to be used only as a guideline. For proper connection, always follow the notes for the
plumbing and heating installer. The plumbing system must meet local, regional or national requirements in force.
Installation and verification of operation are to be performed only by specialised and authorized personnel. The
manufacturer will not be held liable for non-compliance with the provisions listed above.
