tank connector diameter
Safety valve/non-return ap/valve
A non-return ap preceded by a valve must be tted 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.
No non-return valve or ap should ever be tted between the safety valve or safety unit
and the tank.
