Do not use Teflon® tape to seal threaded connections in
solar installations, because the change in the creep behav‐
iour of the water glycol mixture may result in gradual leaki‐
ness.
Instead, use properly manufactured hemp packages.
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

ments is not permitted.
