Treat the water in the installation to limit corrosion, calcium and
limescale deposits, sludge, microbiological contamination, etc..
CAUTION
An uncleaned installation or an installation using water of
unsuitable quality may bring about the cancellation of the
warranty.
For an optimum functioning of the boiler, the water of the installation
must comply with following characteristics:

Recommendations:
4 Reduce the quantity of oxygen in the heating circuit to the
minimum.
4 Limit the annual quantity of water added to the circuit to 5% of the
total water volume in the installation.
4 New installation
- Completely clean the installation of all residues (plastic waste,
installation parts, oils, etc.).
- Use an inhibitor in combination with a softener.
4 Existing installation
If the water quality in the installation is insufficient, several options
are possible:
- Install one or more filters.
- Completely clean the installation to evacuate any impurities and
deposits in the heating circuit. To do this, a considerable and
controlled flow rate is required.
- Clean the boiler (dirt, deposits, calcium, etc.).
