Collector Supply and Return Piping
For the piping connecting the collectors to the Solar

Divicon pumping station, Viessmann recommends the
use of commercial copper pipe and bronze fittings, or
non-galvanized steel pipe. (PEX or other plastic pipes
are not suitable for solar collector supply and return
piping).
Use only high temperature solder or brazing material

when connecting the copper pipes in the collector
piping. The melting temperature should be above
450°F (232°C).
When laying out the collector array, ensure that air

can be properly vented.
