4.4. Hydraulic Installation
It is necessary to install a safety device at the cold water inlet of the appliance. The
safety device must be in compliance with the standard EN 1487:2002, maximum pres-
sure 7 bar (0.7 MPa)Water must not be stopped from flowing from the safety device
to the deposit by any sort of accessory.
The safety device must be connected with piping whose diameter is not less than the
WARNING
cold water inlet coupling. The discharge must be connected to a sewage siphon or,
if this is not possible, elevated to a distance of at least 20 mm from the pavement to
allow visual inspection.
To prevent high pressure from main water supply, install a pressure reduction valve
set to 3 bar (0.3 MPa).
The Manufacture is not responsible for damage related to not following these recom-
mendations/ warnings.
