. For example: antifreeze,
water softeners, products to increase or reduce the pH
value, chemical additives and/or inhibitors. These may
cause faults in the boiler and damage the heat exchanger.

For untreated water, the pH value of the water in the
installation must be between 7 and 9 and for treated
water between 7 and 8,5.
4
The maximum hardness of the water in the installation
must be between 0,5 - 20,0 °dH (Depending on the
total installed heat output).

For more information, refer to our publication water
quality rules. The rules in the aforementioned
document must be respected.
5.11.2. Filling the system
CAUTION
Before filling, open the valves on every radiator in the
