5.3.2. Safety valves:
The safety valves are fi tted to the tank inlet using a T (see diagram below).

No non-return valve or fl ap should ever be fi tted between the safety valve or safety unit
and the tank.
A non-return fl ap preceded by a valve must be fi 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.
