n

Pressure reducer

If the mains pressure exceeds 80% of the calibration of the valve or

safety unit (e.g. 5,5 bar (0,55 MPa) for a safety unit calibrated to 7 bar

(0,7 MPa)), a pressure reducer must be installed upstream of the

appliance. Install the pressure reducer downstream the water meter

in such a way as to ensure the same pressure in all of the installation

pipes.

n

Measures to take to prevent hot water flow return

Fit a one-way valve to the domestic cold water circuit.
