Connecting the domestic cold water
Make the connection to the cold water supply according to the
hydraulic installation diagram.
The components used for the connection to the cold water supply
must comply with the prevailing standards and regulations in the
country concerned.
4
Install a water drain in the boiler room and a funnel-siphon for the
safety unit.
4
Fit a one-way valve to the domestic cold water circuit.
n
Pressure reducer
If the mains pressure exceeds 80% of the calibration of the valve or
safety unit (e.g. 8 bar (0,8 MPa) for a safety unit calibrated to 10 bar
(1,0 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
Domestic hot water circulation loop
To guarantee the availability of hot water as soon as the taps are
turned on, a circulation loop between the draw-off points and the
recirculation pipes in the DHW calorifer can be installed. A non-return
valve must be included in this loop.
Run the domestic hot water circulation loop via the boiler
control system or an additional timer program to optimse
energy consumption.
n
Measures to take to prevent hot water flow return
Fit a one-way valve to the domestic cold water circuit.
