Pipe installation
Pipe installation must be carried out in accordance with
current norms and directives.
VPB/VPBS must be fitted with the requisite valves, such
as a safety valves, shut-off valves, non-return valves and
vacuum valves.
VPB/VPBS must be supplied with a mixing valve, which
limits the temperature of outgoing hot water to 60 °C.
If this valve is not fitted, some other measure must be
taken to prevent the risk of scalding.
Internal support bushes must be fitted when a plastic
or annealed copper pipe is used. An overflow pipe must
be routed from the safety valve to a suitable drain. The
overflow pipe must be the same size as the safety valve.
Route the overflow pipe from the safety valve, sloping

The mouth of the overflow pipe must be visible and not
placed close to electrical components.
Ensure that incoming water is clean. When using a
private well, it may be necessary to supplement with
an extra water filter.
