In presence of water with max hardness 25 °Fr, is prescribed an appropriate
treatment of the heating water, in order to avoid limescale problems and also an
expansion tank.
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
connections. Equally important is to do a pressure test during the operation.
Exceeding above listed limits may cause damages to module and impair warranty
