SAFETY INSTRUCTIONS
General remarks
• Connections (electrical, hydraulic) must be carried out in accordance
with applicable standards and regulations, by an approved installer.
• The start-up and commissioning must be carried out by an approved
installer.
• If the water drawing off point is far from the tank, installing an auxiliary
DHW loop can allow to get hot water more quickly at all times.
Essential instructions for the correct operation of the system
• The appliance must be installed in a dry and protected area.
• Install the appliance to ensure easy access at all times.
• Before fixing the appliance to the wall, make sure that the wall can bear
the weight of the appliance filled up with water.
• In the case of hydraulic connection to a water system made of brass, it
is compulsory to use reduced dielectric sleeves or equal male-female
sleeves made of malleable cast iron. Should the thread of the tubes,
which are not provided with such sleeves, be attacked by corrosion, our
warranty will be void.
• Make sure to install a pressure reducing valve set at 4.5 bar in the DHW
circuit if the supply pressure is higher than 6 bar.
• Do not expose the appliance to pressure exceeding 7 bars, otherwise
the appliance will suffer irreparable damages. Install an approved safety
group, comprised of a safety valve set at 6 bar, a check valve and a stop
valve.
• Make sure that the outlet of the safety unit goes directly to the sewer to
avoid any potential damage and that the drain pipe is never obstructed
and protected from freezing.
• Do not install the safety group above the tank to avoid water discharge
on to the appliance.
• If one or several mixing valves are used, a check valve is to be mounted
to the cold water column supplying the mixing valves. A stop valve must
be installed on the cold water supply of the appliance.
