HYDRAULIC CONNECTIONS
General remark
• The circuit illustrations are basic principle diagrams only.
Essential recommendations for safety
• The hot water output may reach temperatures in excess of 60°C, which can cause
scalding! It is therefore necessary to install a thermostatic mixing valve after the
appliance.
• The system must be fitted with an approved safety group, comprised of a 7 bar
safety valve, a check valve and a shut-off valve.*
Essential recommendations for the correct operation of the appliance
• Flush the system before connecting the domestic hot water circuit. Refer to the
installation instructions.
• Make sure to install a pressure reducing valve set at 4.5 bar if the mains supply
pressure is in excess of 6 bar.
• It is recommended to install an expansion vessel in the DHW circuit to prevent the safety
valve from opening constantly and reduce the water hammer effect in the system.
• If the appliance is used as a domestic hot water preparation tank, a primary
expansion vessel adapted to the boiler power/size and to the type of system must
be fitted in the heating circuit (if there is no built-in expansion vessel, or if the built-
in expansion vessel size is not sufficient).
