DHW CONNECTIONGeneral remark• The circuit illustrations are basic principle diagrams only.Essential recommendation for safety• The hot water output may reach temperatures in excess of 60°C, which can causescalding! It is therefore necessary to install a thermostatic mixing valve after theappliance.• The installation must be fitted with an approved safety group, comprised of a 7 barsafety 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 theinstallation instructions.• Make sure to install a pressure reducing valve set at 4.5 bar if the mains supplypressure is in excess of 6 bar.• It is recommended to install an expansion vessel in the DHW circuit to prevent thesafety valve from opening constantly and reduce the water hammer effect in thesystem.• If the appliance is used as a domestic hot water preparation tank, a primaryexpansion vessel of at least 16 litres must be fitted in the heating circuit, if there isno built-in expansion vessel.HEATING CONNECTIONTypical connection - high temperatureDescription1.
