Anti-Freeze Function - Ariston ABS VLS EVO POWER 30 Instructions For Installation, Use, Maintenance

ANTI-FREEZE FUNCTION

The anti-freeze function is the appliances automatic protection to avoid damages caused by very low
tempe ratures below 5 °C, in the event in which the product is turned off during winter. It is recommended
that the product remains plugged in to the mains power, even if iiis inactive for a long time. The function
is enabled; activation is displayed on the display with "AF". For all models, once the temperature rises to
a safer level such as to avoid damage from ice and frost, the water heating is switched off again.
THERMAL DISINFECTION FUNCTION (ANTI-LEGIONELLA)
The anti-Legionella function is activated by default. It consists of a water heating/60°C temperature main-
tenance cycle for 1 hour which has a thermal disinfection action on the relative bacteria.
The cycle starts when the product is started up and when it is restarted after a power outage. If the
product always functions at temperatures lower than 55°C, the cycle is repeated after 30 days. When the
product is switched off , the anti-Legionella function is deactivated. If the equipment is switched off during
the anti Legionella cycle, the product switches off and the function is deactivated. At the end of the cycle,
the use temperature returns to the temperature previously set by the user.
To activate or deactivate the function, press the "FAST/ " knob for 5 seconds; the display will show
"A0" (deactivated) or "A1" (activated). Turn the knob to change the setting.
To confirm the activation/deactivation, the product will return to the normal operating status after 5
seconds.
