2. Lay the connection pipes up to the roof penetration and fix in
position (e.g. with clamps).
3. Carefully cut open or cut off the thermal roof insulation under
the roof penetration box so the return flow pipe (VA18 Solar)
can be pulled out and laid with sufficient gradient to the roof
penetration box.
4. Run the connecting pipes through the roof at the points pro-
vided. To ensure uninterrupted thermal insulation (also within
the roof structure), the insulation must be resealed at the pen-
etration points (e.g. with adhesive tape).
5. Cut off the thermal insulating hoses of the connecting pipes
so that the pipes can be passed through the individual roof
penetrations.
6. Pull the inflow pipe (top on the flat solar panel/VA15 Solar) as
well as the return flow pipe (bottom on the flat solar
panel/VA18 Solar) through the M32 screw fitting of the re-
spective roof penetration box. Next, push the equipotential
bonding cable and the solar panel temperature sensor cable
through the respective M16 glands from inside.

For on-roof mounting:
Cover the roof penetrations.
– The roof tiles at the side and above must overlap the roof
penetration.
– The corrugated flashing must overlap the roof tile under-
neath and be shaped to match the roof tile.

Step 2
The connecting cable for the solar panel temper-
ature sensor is drawn into the heat insulation hose
together with the inflow connecting pipe. At the joint
of the inflow and return flow connecting pipes, it
must be pulled out of the pre-fabricated connecting pipe
CON… and routed along the return flow connecting pipe to
the bottom panel connection.
For flat roof mounting:
In order to keep the pipe laying as short as possible
in the frost-endangered area (outdoors), ROTEX
recommends installing two separate flat roof penetration
boxes for two-way connection of the solar panel array for the
roof penetration box of the inflow and return flow pipes.
With 3 and more solar panels, the two-way solar panel array
must be connected with 2 flat roof penetration boxes. The
CON FE (
16 47 09) roof penetration box required for
this is equipped with seals for the cable screw fittings. They
must be converted to match the connection type.
