made from metal. Other metal parts of the cylinder that can be
touched and that are in contact with water must be permanently
and reliably connected with the earth conductor.
The max. permissible pressure must not be exceeded (see chapter
"Specification / Data table" and cylinder specification).
f Install a type-tested safety valve in the cold water supply f
line. For this bear in mind that, depending on the static pres-
sure, you may also need a pressure reducing valve.
f Size the drain so that water can drain off unimpeded when f
the safety valve is fully opened.
f Fit the discharge pipe of the safety valve with a constant f
downward slope and in a room free from the risk of frost.
