4. HYDRAULIC CONNECTION

The installation must be done according to current standards.
Do not forget to put a deaerator or a purger at the top of the primary water tank.

4.1. Water quality

From installation until the end of the tank's life cycle, the composition of the water used must
conform to the recommendations for the boiler used with the tank.
• Water supply
The water supply can cause corrosion related to:
• Acidity at the source,
• The presence of oxygen,
• The heterogeneity of metals present
To avoid these phenomena, the water supply must be treated, according to the following
parameters:
• PH: 8.2 to 9.5
• Oxygen scavenger: in excess.
The chemical products used must be carefully and thoroughly introduced. We suggest that
you hire the services of a business specialized in water treatment; they are able to offer:
• Appropriate treatment for the nature of the installation.
• A follow-up contract and performance guarantee.
4.2. Renovation of boilers
For old boilers being renovated, before installing a new element in the unit, be sure to rinse
the tank fully to eliminate all airborne and waterborne particles.
This procedure can be insuffi cient, especially with very old units equipped with heating
fl oors.
A complete sludge removal might then be necessary.
Like with water treatment, this procedure must be carried out by a specialized company that
can defi ne, prescribe and implement treatment products, according to a prior analysis of the
water source parameters and the risk of leaks in the water distribution system.
Before proceeding with the water connection, it is essential to clean the water-supply pipe
properly to avoid introducing metallic or other particles in the tank.
We recommend cold pressure of 1 bar. Check that the hot pressure does not exceed 4 bars
on default settings (or 8 or 10 bars depending on the option chosen).
