Heat pump water heater – OPERATING AND MAINTENANCE INSTRUCTIONS
7.8 Anti-legionnaire's disease protection (function activated only through the installer menu)
If activated, the water heater automatically carries out the anti-legionnaire's
disease protection function. The water is brought to a temperature of 65 °C on a
monthly basis and for a maximum time of 15 minutes, so as to avoid germs from
developing in the water tank and piping (provided the water has not been
brought to T>57 °C at least once for at least 15 minutes). The first heating cycle
is performed 3 days after the function has been activated. As these temperatures
may cause burns, it is advisable to use a thermostatic mixer.
During the cycle of anti legionnaire's will be displayed "ANTI_B" alternately to the
mode of operation, once the cycle is done the set temperature remains the
original one.
To stop press "on/off".
