6.1.6 Flexible water coil pipes considerations
Process for coil pipes connection (to avoid leakage).
1 Put a gasket inside the nut.
a)
Nut
Gasket
c)
2 Check that the nut turns free.
3 Be sure that the tube is aligned with the connection.
4 IMPORTANT! Ensure that the gasket is in contact and it is
seating uniformly with the connection.
5 By hand, rotate smoothly the nut and screw it into the
connection. The screwing may be easy and it should not
offer too much resistance, so if that happens, loosen the nut
and check that the pipe and the gasket position are correct
and proceed again with point 3 and 4.
6 With a spanner, finish the screwing process of the nut until
firm but without damaging the gasket.
