5.4.5 Domestic water hygiene
If no hot water is used for several days and the storage tank temperature of the Solaris system does not reach at least 60 °C,
we recommend that for reasons of hygiene (legionella protection), the stored water should be heated once to over 60 °C or that
the stored hot water should be drained (see technical data in the storage tank manual).
