5. Applications
For installations of domestic hot water provide for a filter to protect the safety of
the systems. It is suggested to install a check valve and an expansion in AFS line
as shown in par. 5
In presence of water with hardness above 25 ÷ 30 ° Fr, is prescribed an appropri -
ate 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
connections. Equally important is to do a pressure test during the operation.
Exceeding above listed limits may cause damages to T_FAST-I module and impair
warranty terms consequently
