the systems. It is suggested to install a check valve and an expansion in AFS line.
In presence of water with hardness above 25 ÷ 30 ° Fr, is prescribed an appropriate
treatment of the heating water, in order to avoid limescale problems. It should
be noted that even a small quantity of limescale, could reduce the performances
of the domestic side.
The materials of construction are in compliance with the Directive 98/83 EC.
Despite the fittings are mounted at the factory, it is advisable to monitor all screw
