Water connection

Risk of damage
Carry out all water connection and installation work in
accordance with regulations.
If the water pressure is higher than 0.5 MPa, install a
pressure reducer in the cold water inlet.
ª Thoroughly flush out the cold water line before connecting
the appliance, so that no foreign matter gets into the cylinder
or safety valve.
ª Route the drip water outlet of the safety valve to a drain free
from the risk of frost, with a constant slope to ensure the
unrestricted flow of the water to the drain. The drip water
outlet must always remain open to the atmosphere.
