Collectors must be connected in series through connectors and seals. Series far end: if hoses as connection elements are not provid-
ed, it is recommended to provide connection ducts with suitable devices for compensation of deformations caused by temperature
inversions (dilatation arches, hoses, compensation connectors). In these cases it is possible to connect max. 6 collectors in series.
Check the proper positioning of flat seals in their seat.

Do not fix the ends of lines of solar collectors rigidly: leave them free to absorb thermal expansion. If this is not possible, fit an
expansion joint at each end.

If copper pipes are used, joints must be hot brazed.

We recommend the use of stainless steel pipes specially made for solar collectors for the outlet, return and probe pipes. The
probe cable should be of the shielded type.

Do not use plastic or multistrate pipes. Operating temperature can exceed 180°C.

Pipe lagging must be able to resist high temperatures (180°C).
