This electronic storage water heater is sold with a thermal disinfection cycle function not enabled for default; as a
consequence, if, for any reason, one of the above said "Conditions for Legionella growth" could occur; it's hardly
recommended to enable such function by following the instructions mentioned in this booklet [see par. 7.7].
However, this thermal disinfection cycle is not able to destroy any Legionella bacteria in the storage tank; so, if this
function is then disenabled, Legionella bacteria growth might re-take place again.
Note: when this software carries out the thermal disinfection treatment, the energy consumption of the storage water
heater is expected to increase.
Warning: when this software has been carrying out the thermal disinfection treatment, water temperature can cause
severe burns instantly. Children, disabled and elderly are at highest risk of being scalded. Feel water before
bathing or showering.
