Domestic water
Water may drip from the safety valve’s
overflow pipe. The overflow pipe must be
routed to a suitable drain, so hot water
splashes cannot cause harm. The entire
length of the overflow pipe must be inclined
to prevent water pockets, and must also be
frost-proof. The overflow pipe must be at
least the same size as the safety valve. The
overflow pipe must be visible and its mouth
must be open and not placed close to elec-
trical components.
VVM 310 must be installed via an isolator
switch. The cable area has to be dimen-
sioned based on the fuse rating used.
