Header connection
Information on laying the header pipes can be found in
the complete station installation instructions.
The pipework connection to the header pipes is made
using the long flexible connection pipes. It is not permit-
ted to connect a fixed header pipe directly to the collec-
tor.
i
USER NOTE
Use standard ventilation tiles or lead
flashing when laying the connection pipes
under the roof.
Use a specialist company to route
the connection pipes under the roof.
i
USER NOTE
Feed the sensor cable together with the
flow line through the ventilation tile under
the roof.
i
USER NOTE
If you intend to vent the solar heating sys-
tem with an automatic air-vent valve (ac-
cessory) at the highest point of the
system, run the flow line rising to the air-
vent valve and the return line rising to the
collector array.

De-airing through pressure filling
If venting of the solar heating system is carried out using
a pressure filling pump, no vent is required on the roof.
B Push connection pipe (1.000 mm, Fig. 53, Item 1)
onto the flow connection on the collector array and fix
in place using bracket (Fig. 53, Item 4).
B Feed connection pipe together with the sensor cable
through the ventilation tile (Fig. 53, Item 3) and
through the roof insulation.
B Connect header pipe to the compression fitting
(Fig. 53, Item 2).
Perform the same procedure with the return connection.
