The solar storage cylinders IDRA N DS,with a double coil and
a capacity of 1500 and 2000 litres, can be integrated into solar
systems for producing domestic hot water with collectors.
The main technical elements of the design of the solar storage
cylinder are:
- the careful study of the geometries of the tank and the coils that
allow you to obtain the best performance in terms of stratifica-
tion, heat exchange and reactivation times
- the internal vitrification, bacteriologically inert, to ensure maxi-
mum hygiene of the water processed, to reduce the possibility
of limestone deposit and make cleaning easier
- the regulation of the connections to various heights for employ-
ing various types of heat generators, without influencing the
stratification
- the polyurethane insulation without any CFC and the elegant
outer covering to limit dispersion and to improve efficiency
the use of the flange to facilitate cleaning and maintenance,
and the magnesium anode with an "anti-corrosion" function
The IDRA N DS storage cylinders can be equipped with a spe-
cific solar regulator and they can easily be inserted into solar
equipment where the boilers or thermal systems act as auxiliary
producers of heat.
The IDRA N DS solar storage cylinders can be identified by:
b Tampering, removal, lack of identification labels or anything else which does not
permit the safe identification of the product, makes any installation and mainte-
nance operation difficult.

b Having completed the assembly, attach the serial number,
the technical data label and the product label which enable
a secure identification of the storage unit (see positions on
page 6).
The IDRA N DS solar storage cylinders can be installed in all rooms where a level of electrical protection of the appliance above IP
X0D is not required.
bThe room where it is installed should be dry, to prevent rust forming.
b In order to make the installation, assembly, inspection and ordinary and extraordinary maintenance operations easy, the minimum
distances must be maintained and the installation room of the storage cylinder must be easily accessible. In particular, access to
the room must allow, among other things, the possible total removal and re-installation at the end of the storage cylinder's useful
life. The user is, therefore, responsible for any costs for removal of masonry work or anything else making it impossible or hard to
access the installation room of the storage cylinder.

Schematic diagram
b When using unsoftened water, it is recommended that the
maximum temperature of the storage cylinder be set at
60°C, since at higher temperature limestone will deposit
with the resulting deterioration of the heat exchange.
b Before commissioning the solar equipment, the boiler
must be filled with water.
b If a solar storage unit is being used with network pressure
greater than 4 bar, plan to use a pressure reducer.
b Be careful not to get burned when opening the vent valves
of the solar equipment.
b The expansion tank must resist high temperatures and
the membrane must not come into contact with the water-
glycol mixture.
b IT IS OBLIGATORY that the sanitary system include the
expansion tank, the safety valve, the automatic vent valve
and the storage cylinder discharge tap.
b The safety valve outlet must be connected to a suitable
collection and venting system. The manufacturer of the
storage cylinder waives all liability for any flooding caused
by the intervention of the safety valve.
b To limit the temperature of the domestic hot water use a
thermostatic mixer valve.
b If there is a drop of pressure in the solar equipment DO
NOT fill with water but with water-glycol mixture: risk of
freezing.
b All the piping installed including the collectors, the
exchangers and the hydraulic devices, must undergo seal
tests.
b The selection and the installation of the components of
the system is referred to the expertise of the installer, who
must operate according to the rules of good technique and
current Legislation.

Before the start-up and before testing the
the storage cylinder, it is absolutely necessary to check that:
- The water supply taps of the domestic water circuit are open
- The water connections to the respective boiler and to the water
unit of the solar equipment have been carried out correctly
- The procedure for washing and filling up of the solar heating
circuit with the water-glycol has been carried out correctly, and
the equipment has been de-aerated at the same time.
The transfer of heat into the solar heating circuit takes place
when the temperature of the solar collector is higher than that of
the storage cylinder. Therefore in managing the solar equipment
the exact temperature is not important, but rather the tempera-
ture difference.
- Set the temperature difference between the collector and the
storage cylinder (see the instruction manual of the regulator).
- Commission the boiler for the auxiliary heating of the storage
cylinder.

lector surface
- The solar heating circuit is completely vented
- The cold pressure of the equipment is about 3 bar
- The safety valves intervenes at 6 bar
- The piping of the hydraulic supply are insulated in full respect
of current regulations.
