ATTENTION
A magnesium anode, that is placed inside the
tank, protects the whole appliance against
galvanic corrosion. It has to be replaced every 8 -12
months for warranty purposes.
A pressure relief and non return valve protects the
tank against excessive pressure due to the volume
increase of water while heating; moreover it prevents
domestic hot water from flowing back into the cold
water circuit. The lack of a suitable pressure relief
valve causes the warranty on the storage tank to be
invalided.

SAFETY DEVICES

Pressure relief and non return valve
The pressure relief and non return valve (1) supplied
with the appliance protects the tank against possible
excessive pressure due to the volume increase of water
while heating; moreover it prevents domestic hot water
from flowing back into the cold water circuit.
The protection from
foresees the expulsion of a given mass of water in case
the pressure inside the tank exceeds 6 bar in order to
bring the pressure back to optimum values. At the same
time a given mass of cold water will get into the tank
lowering the temperature of water.
ATTENTION
If the appliance is installed in Italy, the
pressure relief
appliance must be replaced with a safety group in
accordance with the UNI rule EN 1487:2002 (as

overpressure or overheating
valve supplied with
required by The Memorandum N° 9571 dated 2 6/03/03
issued by Ministry of Productive Assets - G.U. N° 87
of 14/04/03). In case of non-installation of a safety
group in compliance with the rule EN 1487, the
manufacturer will be exempted from any warranty
claim on the tank.
ATTENTION
If the
overpressure may damage nearby objects, we
suggest to foresee a suitable draining system in
order to avoid any problem.
The water inside the tank can reach very high
temperatures (over 60 °C): for this reason in order to
avoid any risk of burning it is necessary to install a
water mixer expecially when we foresee to use the
hot water taking it directly from the panel.
ATTENTION
DANGER OF SERIOUS BURNS
If the appliance is located in a place easily
accessible to people, do not approach it during the
day because there could be a high temperature. Keep
children away from the water heater, fencing the
appliance if necessary.
Warning labels
Some labels stuck on the appliance highlight some
important warnings.
Each dangerous point is marked with a suitable label.
Keep the labels clean and legible; replace those that are
missing or damaged.
