3.3.2
Potential equalisation
DANGER!
Danger due to electrical current
An electric shock can lead to burns and serious injury and
even death.
Because all metallic piping systems conduct electricity,
unintentional contact with a live part can lead to the whole
piping system and components connected to it (e. g. radia-
tors) becoming energised.
– Only allow electrical work to be carried out by qualified
electricians.
– Always integrate the metallic piping system into the
potential equalisation.
It is the fitter of the electrical system who is responsible for
ensuring that the potential equalisation is tested and
secured.
3.3.3
Permitted exchange of sealing elements
Important instruction
With their material-specific qualities, sealing elements in
press connectors are adapted for use with the corre-
sponding media and/or the areas of use of the piping sys-
tems and are generally only certified for them.
The exchange of a sealing element is generally permitted.
The sealing element must be exchanged for a designated
spare part for the intended application
Ä
Chapter 2.3.4
„Sealing elements“ on page 15. The use of other sealing
elements is not permitted.
If the profile sealing element in the press connector is obviously dam-
aged, it should be exchanged for a Viega replacement profile sealing
element made of the same material.
3.3.4
Space requirements and intervals
The minimum distance to welding seams and bending points must be
3 x D – however at least 100 mm.
