1.3 HYDRAULIC CONNECTION.
Before making the connections, all of the system piping must be
washed thoroughly to remove any residues that could compromise
the good functioning of the storage tank. Water connections must
be made in a rational way.
N.B.:
while performing the connection, set up a drain fitting and
an interception cock at the cold water inlet (AF) to facilitate main-
tenance operations. The storage tank safety valve outlet must be
connected to a draining funnel. If this is not the case, the storage
tank manufacturer declines any liability in the event of flooding
if the drain valve cuts in.
Unused DHW side hydraulic connections are to be closed with
hydraulic seal caps.
All connection fittings must be adequately insulated to minimise
heat dispersion.
Insulated caps to be applied on unused fittings during installation
are standard supplied.
Attention:
to preserve the duration of the D.H.W. heat exchanger’s
efficiency features, we recommend the installation of a device to
reduce the formation of lime scale in presence of water whose char-
acteristics can lead to lime scale deposits.
1.4 SYSTEM FILLING.
On connection of the storage tank, fill the system. Filling is per-
formed at low speed to ensure release of air bubbles in the water
via the heating system vents.
The filling valve must be closed when the pointer on the boiler
manometer indicates about 1.2 bar (see boiler instruction book).
1.5 DOMESTIC HOT WATER STORAGE TANK UNIT.
The storage tank unit must be connected to a boiler, solar panel
system or heat pumps.
Storage tanks are insulated with high-performing insulating
materials that can limit heat dispersion. The insulating material
on Inoxstor 200 and 300 litre models is about 60 mm thick and
about 80 mm thick on Inoxstor 500 litre model.
- Boiler protection: this storage tank is manufactured with a stain-
less steel casing and bottom, which guarantees a long life. The
assembly concepts and welding (T.I.G.) are implemented to the
minimum detail to ensure maximum reliability.
- Efficiency: the coiled heat exchange surface is sized to supply
large quantities of hot water.
- The storage tank has two seats to include the sacrificial anode,
which is supplied as standard to protect the inner part of the
storage tank against corrosion; one is on the upper part and the
other is on the side of the storage tank.
N.B.:
annually check (e.g. the Authorised Technical Assistance
centre) efficiency of the sacrificial anodes.
