1.1 INSTALLATION
RECOMMENDATIONS.
Only professionally enabled companies are au-
thorised to install Immergas appliances.
e place of installation of the appliance and
relative Immergas accessories must have suitable
features (technical and structural) such to allow
(always in safety, efficiency and comfortable
conditions):
- installation (according to the provisions of the
technical legislation and technical regulations);
- maintenance operations (including scheduled,
periodic, routine and special maintenance);
- removal (to outdoors in the place for loading
and transporting the appliances and compo-
nents) as well as their eventual replacement
with appliances and/or equivalent components.
Installation must be carried out according to
regulation standards, current legislation and
in compliance with local technical regulations
and the required technical procedures. Before
installing the storage tank unit, ensure that it is
delivered in perfect condition; if in doubt, contact
the supplier immediately. Packing materials (sta-
ples, nails, plastic bags, polystyrene foam, etc.)
constitute a hazard and must be kept out of the
reach of children.
If the storage tank unit is installed inside or
between cabinets, ensure there is sucient space
for normal servicing. It is advisable to leave an
adequate gap between the storage tank casing
and the sides of the cabinet.
In the event of malfunctions, faults or incorrect
operation, turn the storage tank o and contact
an authorised company (e.g. the Authorised
Technical Assistance centre, which has specical-
ly trained sta and original spare parts). Do not
attempt to modify or repair the appliance alone.
Failure to comply with the above implies personal
responsibility and invalidates the warranty.
• Installation standards: check the features of the
installation area in advance, in terms of overall
dimensions and weight of the cylinder, setting
up a supporting surface under the storage tank
if necessary, to optimise weight distribution.
ese storage tanks have been designed for
oor installation only; they must be used for
the storage of domestic hot water and similar
purposes. ey have not be designed for wall-
installation. Ensure that the useful heat output
of the generator is at least 15% higher than the
heat output that can be absorbed by the stor-
age tank, and that the volume and factory-set
pressure of the expansion tank of the secondary
circuit are suitable for the system;
Attention: this storage tank unit is designed to
produce and store hot water, it must therefore
be connected to a heating system, to a domestic
hot water distribution network and to the water
system, compatibly with its specications and
heat output. e materials used for installation
and connection must be fully compatible with the
minimum characteristics required for solar use.
It must also be installed in rooms where the
temperature cannot fall below 0°C. It must not
be exposed to the eects of the weather.

1.3 CONNECTION.
Hydraulic connection. Before making the
connections, all of the system piping must be
washed thoroughly to remove any residues that
could compromise the proper operation of the
storage tank. Water connections must be made
in a rational way.
Attention: to preserve the duration and eciency
of the domestic hot water exchanger it is recom-
mended to install the “polyphosphate dispenser”
kit (or other device in compliance with Standard
in force and perfectly) in the presence of water
whose characteristics can give rise to scale deposits
(in particular, and as an example, the device is
recommended when water hardness is higher than
25 French degrees).

1.4 FILLING THE SYSTEM.
When the storage tank has been connected, ll
the system. Filling is performed at low speed to
ensure releasing any air bubbles contained in the
water through the vents installed on the central
heating system.
Close the lling valve when the boiler manom-
eter pointer indicates approx. 1.2 bar (see boiler
instruction book).

1.5 DOMESTIC HOT WATER STORAGE
TANK UNIT.
e storage tank unit must be connected to a
boiler and a solar panel system. It contains large
coiled heat exchanger pipes, which help notably
reduce hot water production times.
- Boiler protection:
- Vitried steel Storage Tank Units: treatment
with glazed enamel (also called vitrication),
gives the product a high capacity of inalter-
ability of the chemical-physical features of
the domestic hot water.
Additional quality support is provided by
magnesium anodes installed, by standard, on
the product. On request it is possible to install
impressed current anodes.
- Eciency: the coiled heat exchange surface is
sized to supply large quantities of hot water.
- Heat insulation: the storage tanks with a capac-
ity of 1000, 1500 and 2000 litres are insulated
with exible polyurethane with a thickness of
100 mm., CFC and HCFC-free.
- External casing: this is made of a coupled PVC
sheath.
N.B.: every year a skilled technician (e.g. Au-
thorised Aer-sales Service), must check the
eciency of the storage tank unit's Magnesium
Anode. e storage tank unit is prepared for
introduction of the domestic hot water pump
tting.
1.6 KITS AVAILABLE ON REQUEST.
• Recirculation kit (on request). e storage tank
unit is prepared for application of the pump

2USE AND MAINTENANCE INSTRUCTIONS
2.1 CLEANING AND MAINTENANCE.
e user is advised to service the storage tank
unit on an annual basis.
is ensures that the optimal safety, performance
and operation characteristics of the storage tank
unit remain unchanged over time.
2.2 OPERATION.
is storage tank allows easy provisioning of
water for domestic use and industrial use.
e storage tank is connected to the water dis-
tribution network via the cold water tting and
to the utilities via the hot water tting.
If a utility withdraws hot water, the cold water
enters the tank where it is heated to the tempera-
ture set on the thermostat.
It is recommended to adjust the temperature
between 60 and 65°C because this temperature
guarantees the best performance of the storage
tank unit and at the same time ensures:
- maximum hygiene
- maximum savings
- delay in lime scale formation
e DHW in the storage tank is heated with
the passage of CH/solar water, which circulates
inside the coils inside the storage tank unit itself.
In all cases the maximum temperature inside the
storage tank unit must not exceed 99 °C.
2.3 EMPTYING THE STORAGE TANK
UNIT.
To drain the storage tank, use the special drain-
ing valve in the lower part of the storage tank.
Before draining, ensure that the DHW inlet
valve is closed.
2.4 CLEANING THE CASE.
To clean the outer parts of the storage tank, just
use a cloth dampened with product suitable for
the purpose that can be found on the market.
Abrasive, solvents, petrol and alcohol products
are not recommended.
2.5 DECOMMISSIONING.
In the event of decommissioning the storage
tank, contact an authorised company for the
relative operations, among other things making
sure that water supply is disconnected.
At the end of its service life the appliance must
not be disposed of like normal household waste
nor abandoned in the environment, but must
be removed by a professionally authorised
company. Contact the manufacturer for disposal
instructions.

3.2 YEARLY STORAGE TANK UNIT
CHECK AND MAINTENANCE.
e following checks and maintenance should
be performed at least once a year.
- Check for water leaks or oxidation from/on the
ttings;
- Visually check that the safety and control
devices have not been tampered with, in par-
ticular:
- adjustment probes;
- expansion vessel;
- safety valve on D.H.W. side;
- Check the integrity of the storage tank Magne-
sium Anode.
- In case of particularly hard water it is advisable
to remove the lime scale from the storage tank
at least once a year. To do so, it is necessary to
empty the tank from the draining valve, remove
the ange to access the inside, and then use a
plastic or wooden spatula to remove the most
stubborn sediments, then clean and rinse again
with a jet of water.
- During cleaning, be very careful not to damage
the protection inside the tank.
3.3 STORAGE TANK UNIT TECHNICAL DATA
- When you have completed the process, put the
ange back in place using the gasket (it if is
damaged, replace it with a new one), close the
draining valve and ll the tank ensuring that
neither ange or valve are leaking.
