The collectors in a line are connected so that the heat transfer fluid goes through them in parallel. Therefore the four
copper tubes between the collectors are connected between them by brass compression fittings for copper pipes. Two
out of four of the copper tubes of the extreme collectors of the line must be sealed with brass compression stop ends.
The connection with the heat transfer circuit that goes toward the heat exchanger must be the one near the sensor pocket
of the last collector of the line. The connection with the circuit that comes back from the heat exchanger must be at the
bottom of the first collector of the line (see the picture above).
It is also possible to connect more then one line of solar collectors using brass compression elbows or welding the tubes
of the circuit.
Multi-collector installations must consist of strings of the same number of collectors (see the following sample diagrams).
