LEGIONELLA BACTERIA FUNCTION
Legionella are small rod shaped bacteria which are a natural constituent of all fresh waters. Legionaries'
disease is a pneumonia infection caused by inhaling of Legionella species. Long periods of water stag-
nation should be avoided; it means the water heater should be used or fl ushed at least weekly.
The European standard CEN/TR 16355 gives recommendations for good practice concerning the pre-
vention of Legionella growth in drinking water installations but existing national regulations remain in
force.
This electronic storage water heater is sold with a thermal disinfection cycle function enabled by default.
Every time the product is switched on and every 30 days, the thermal disinfection cycle runs to heat the
water heater up to 60°C.
Warning: when this software has been carrying out the thermal disinfection treatment, water tempera-
ture can cause burns. Feel water before bathing or showering.
