NOTICE
In case of plastic pipes, make sure they are fully oxygen diffusion tight according to
DIN 4726. The diffusion of oxygen into the piping can lead to excessive corrosion.
▪
Connecting piping - Legislation. Make all piping connections in accordance with
the applicable legislation and the instructions in the "Installation" chapter,
respecting the water inlet and outlet.
▪
Connecting piping - Force. Do NOT use excessive force when connecting the
piping. Deformation of the piping can cause malfunctioning of the unit.
▪
Connecting piping - Tools. Only use appropriate tooling to handle brass, which is
a soft material. If NOT, pipes will get damaged.
