No non-return valve or flap should ever be fitted between the safety valve or safety unit
and the tank.
A non-return flap preceded by a valve must be fitted to the cold water inlet if the tank is
equipped with a safety valve. To avoid scaling of these components, operate the safety unit
at least once a month by moving its controls to various positions.
