1. Safety instructions
Â
HVI Conductors
may only be installed under the conditions shown and referred to in these instal-
lation instructions.
Â
Only qualified and trained personnel (lightning protection specialists) may install
HVI Conductors
.
We recommend to visit a special training course on
HVI products
held by DEHN.
Â
For safety reasons, installation work must be stopped as soon as a thunderstorm approaches/is
noticed.
The components of the
HVI system
have been tested as a complete system. Mixing compo
-
nents of the
HVI system
with components from other manufacturers is not permitted.
Â
Prior to installation,
HVI Conductors
must be examined for good order and condition. If damage or
any other defect is found, the
HVI Conductor
must not be installed. The black sheath of
HVI
Con-
ductor
must not be damaged by compressive deformation or cuts.
Â
When using
HVI Conductors
in potentially explosive atmospheres, fire and explosion protection
measures must be taken.
Â
If
HVI Conductors
are installed on thatched roofs (e.g. reed, straw), special installation conditions
must be observed for these flammable locations. These special installation conditions for
HVI
Con-
ductors
are described in our Lightning Protection/Earthing main catalogue (HVI Lightning Protecti
-
on for Thatched Roofs).
Â
If the supporting tube is led through a roof, the roof must be properly sealed. Warm roofs must be
properly sealed and insulated.
Â
HVI Conductors
are suitable for outdoor use and can be installed downstream of the sealing end
e.g. on roofs, in walls, under plaster, in concrete or on facades/facade constructions. Only
HVI Con-
ductors
with an additional
grey sheath
may be installed in the soil, e.g. to connect the down con
-
ductor installed on the building to the ring earth electrode over a length of max. 2 m.
HVI Conduc-
tors
must not be used to locally increase the potential gradient area in the soil (risk of step voltage).
Â
Soiled
HVI Conductors
can be cleaned with a cloth soaked with a special cleaning agent (Part No.
297 199). To be able to comply with dangerous goods regulations, this product is only transported
within Germany and Austria. ISOPROPYL ALCOHOL (99.1 to 99.9 %) (CSA No. 67-63.0) can be used
as an alternative!
