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.
6.1 Water inlet and outlet pipes
The specification of the water inlet or outlet (internal) thread is DN20 (RC3/4”). Pipes must be heat-resistant and
durable.
