Emptying the boiler

It is advisable to drain the water from inside the
boiler if the boiler is idle for a certain period of time,
especially in low temperatures.
It is sufficient to disconnect the water supply input
connection (see paragraph 5).
N.B.: It is important to empty the system
in case of low temperatures in order to
avoid the water freezing.
If the product is not being used for a long
period, beside empting the boiler it is
advisable to unplug the socket since the
equipment is provided with an anti-frost
function that could start uselessly, even if
the boiler is empty.
