line. Please note that, depending on the static pressure, you
may also need a pressure reducing valve.
f Size the drain so that water can drain off unimpeded when
the safety valve is fully opened.
f Connect the hydraulic connections with flat gaskets.
f Fit the discharge pipe of the safety valve with a constant
downward slope and in a room free from the risk of frost.
