▪ Fill the pipes with nitrogen gas to avoid copper corrosion
during brazing.
▪ Braze the connections. Cool the copper tubes during brazing
with a wet rag.
3Install the sealings.
▪ Remove the adhesive release paper from the sealing.
▪ Install the sealing around the correct branch. As the
diameter of the copper tubes differ for each branch, make
sure to use the correct sealing set for each branch.
