Installation Instructions - DEHN (UK)

2. Connection / installation of the HVI conductor
The rafter holder allows two different installation options:
Installation option 1
The HVI conductor / HVI conductor light in the
supporting tube (3.2 m in length with air-termination
tip) or DEHNcon-H is installed above the roofing and
routed to the earth-termination system along the
wall (see also Fig. 16, page 15).
Before installing the supporting tube on the rafter
holder, the prewired HVI conductor / HVI
conductor light has to be led through the supporting
tube (see Fig. 7).
Proceed as follows:
- Insert (if required, slightly turn) the HVI
conductor light in such a way that the
threaded head piece (M10) protrudes from the
supporting tube.
- Securely tighten the lock nut (M10) against
the threaded bolt.
- Firmly fix the hexagonal connector (M10/M10)
with the lock nut.
- Firmly connect the air-termination tip to the
hexagonal connector and tighten (see Fig. 7).
