Warning! If a solar energy solution is installed, the water temperature can rise very quickly. Preventive
measures must be taken for the piping connections.
Note! If the water pressure is too high (above 5 bars), a pressure reducer should be installed at the water
inlet. This is the installer´s responsibility.
In principle, arrange the water pipes connections as illustrated in the above figure example.
Note! A safety valve should be installed at the water inlet of the unit.
